     FIELD OF THE INVENTION 
       [0002]    The invention relates to In-Building Communications (IBC) systems, distributed antenna systems (DAS), public safety communication systems, and emergency communication systems with portable, uninterruptible, hot swappable power systems. 
       BACKGROUND OF THE INVENTION 
       [0003]    Problems with In-Building Communication are described in the Phoenix Fire Department Radio System Safety Project, Final Report, Version 1.7, dated Oct. 8, 2004, which is hereby expressly incorporated by reference and in the National Public Safety Telecommunications Council, NPSTC, Best Practices for In-Building Communications, dated Nov. 12, 2007, which is hereby expressly incorporated by reference. 
         [0004]    During an emergency, fire department communications depend on land mobile radio systems. Land mobile radio systems are allowed to operate in portions of the radio spectrum under rules administered by the FCC. Portions of the spectrum are divided into bands where land mobile radio systems operate with frequencies in the 30 MHz (VHF low), 150 MHz (VHF high), 450 MHz (UHF), 700 MHz, and 800 MHz bands. Fire department communication systems may also use 154,280 (MHz) as this frequency is designated by the FCC as a mutual-aid radio channel. The bandwidth of radio channels, the amount of radio spectrum used by the signal transmitted by the radio, is set by the FCC to include a maximum and a minimum bandwidth for channels in each frequency band. A frequency number indicates the center of each radio channel with half of the bandwidth located on each side of the center. 
         [0005]    Based on the limited radio spectrum, permitted bandwidth has been decreasing. Previously, channel bandwidths were 25 kHz. Newer rules require reducing bandwidths to 12.5 kHz. As the bandwidth has become more crowded, there is increasing difficulty to ensure quality reception. The reduced bandwidth means reduced energy to carry the same amount of information over the same distance increasing the challenge of reliable communications. The 800 MHz band is typically considered to have reduced naturally occurring interference. However, the large number of cellular phone company and other spectrum users has led to increasing man-made interference in the 800 MHz band. 
         [0006]    During land mobile radio communications, a radio signal is sent from a transmitter to a receiver starting when the transmitter generates electromagnetic energy. This electromagnetic energy is converted by an antenna into electromagnetic waves. One type of electromagnetic radiation used in communication is commonly referred to as radio waves or radio signals. Radio waves sent outward from the antenna of the transmitter to the antenna of a receiver are considered downlink transmissions. The antenna of the receiver converts the electromagnetic waves back into energy, which is directed through a transmission line to a receiver. Radio waves then sent from the receiver to the original transmitter are considered uplink transmissions. When both the uplink and downlink transmissions are transmitted on the same frequency, it is considered simplex communication. Typically, one radio user may communicate directly with another radio user using simplex communications. In duplex mode of operation, when a radio user transmits a message, the message is received by a tower, which then retransmits the radio signal to other portable radio users. In half duplex operation or repeated radio communication, two radio frequencies are used for communication. The transmitting radio transmits on a first frequency to a repeater. The repeater then repeats the transmission on a frequency 2 and the signal is received by the receiving radio. Line-of-Sight (LOS) describes an unobstructed free-space link from a source antenna to a receiving antenna. 
         [0007]    Variations in the signal level at the receiver may be due to manmade sources or natural structures including multipath interference, internal noise in the electronic circuit, structures blocking or obstructing pathway of the radio waves, natural noise, near-far interference, intermodulation interference, receiver desensitization interference, or receiver overload. 
         [0008]    Typically, one of the most important factors for effective radio coverage is the location and orientation of the antenna to provide a direct path between the transmitter and the receiver. Important properties of the antenna include operating frequency, polarization, and radiation pattern. Optimizing these properties of the antenna in the desired range may provide improved radio coverage in desired areas and reduce interference in undesired directions. In particular, a directional antenna such as a Yagi antenna or a panel antenna may be used to provide a signal with increased gain near the front of the antenna and a weaker signal from the back. 
         [0009]    In typical fire service operation, portable handheld radios powered with rechargeable or replaceable battery packs are used to communicate with base station radios, which may be powered by AC utility power. Mobile radios are designed for use in vehicles and may be powered from the vehicle&#39;s electrical system. Repeaters are capable of transmitting and receiving signals at the same time and can be used to extend the coverage of portable or mobile radios. Analog radios use frequency modulation to transmit a signal directly correlated to the microphone audio. Digital radios may also be used which have better spectrum efficiency than analog radios and have increased radio reception range in weak signal conditions relative to analog radios. 
         [0010]    The Association of Public Safety Communications Officers (APCO) developed P25 as the standard in digital radio communications in preparation for the move to digital technology. While P25 was intended to serve as a common digital language for the radios and system infrastructures, system manufacturers developed proprietary features resulting in a loss of interoperability. Further, due to difficulty of digital radios to distinguish between high background noise levels and spoken voice data has led to P25 digital portable radios not being recommended for fire-fighting applications when an SCBA facepiece is being used. Analog modulation is preferred for situations where an SCBA (Self Contained Breathing Apparatus) facepiece is used, while law enforcement operations and emergency medical incidents and support functions by the fire department are likely to utilize digital radio technology. As a result of these different functional needs and preferences among the different personnel arriving at the scene of an emergency, different choices in radio equipment has been made increasing concerns over interoperability between different agencies using different models and radios from different manufacturers at the scene of a single event. 
         [0011]    Free-space loss (FSL) is the loss in signal strength of an electromagnetic wave that results from a line-of-sight path through free space, which assumes no obstacles in the path to cause reflection or diffraction. The FSL is proportional to the square of the distance between the transmitter and receiver and also inversely proportional to the square of the wavelength and proportional to the square of the frequency. Other factors like the gain of antennas used by the transmitter or receiver or the loss associated with hardware imperfections are typically not considered in the FSL calculation. The equation for FSL is as follows: 
         [0000]      FSL=(4π d /λ) 2  
 
         [0000]      FSL=(4π df/c ) 2  
 
         [0000]    where λ is the signal wavelength in meters; 
         [0012]    f is the signal frequency in hertz; 
         [0013]    d is the distance from the transmitter; and 
         [0014]    c is the speed of light in a vacuum, 2.99792458×10 8  meters per second. 
         [0000]    FSL may also be expressed in terms of decibel (dB). 
         [0000]      FSL(dB)=10 log 10 (((4π/ c ) df ) 2 ))
 
         [0000]    In radio applications, using f, in units of MHz and d in units of km provides the following relationship. 
         [0000]      FSL(dB)=20 log 10 ( d )+20 log 10 ( f )+32.45 
         [0015]    As the electromagnetic energy in the radio wave spreads out over free space there is a reduction in power of the signal. This is shown by the following equation. 
         [0000]        S=P   t (1/(4π d   2 ))
 
         [0000]    where:
 
S is the power per unit area or power spatial density (in Watts per meter squared) at distance, d, and P t  is the total power transmitted (in Watts).
 
         [0016]    The receiving antenna&#39;s aperture is a measure of how well an antenna can pick up power from an incoming electromagnetic wave. This relationship for an isotropic antenna is shown in the following equation: 
         [0000]        P   r   =Sλ   2 /4π
 
         [0000]    where P r , is the received power. The total loss is given by the following equation: 
         [0000]      FSL= P   t   /P   r    
         [0017]    Additionally, as the radio wave travels from the transmitter to the receiver, different paths traveled by the electromagnetic waves before reaching the receiver may affect the signal quality. Objects in the path of the radio waves such as buildings, trees, or local terrain will reduce the strength of the waves by absorbing or interrupting the signal. The density, size, shape, and type of material obstructing the path of the waves will determine if the waves are reduced, blocked, absorbed, or reflected before reaching the receiver. The final engineered system should consider all the gains and losses in a specific structure to provide a more realistic expectation of coverage according to the following equation: 
         [0000]        R×P=T×P+T×G−T×L− FSL−ML+ R×G−R×L  
 
         [0000]    where: 
         [0018]    R×P=received power in dBm; 
         [0019]    T×P=transmitter output power in dBm; 
         [0020]    T×G=transmitter antenna gain in dBi; 
         [0021]    T×L=transmitter losses (coax, connectors . . . ) in dB; 
         [0022]    FSL=free space loss or path loss in dB; 
         [0023]    ML=miscellaneous losses (fading, body loss, polarization mismatch, other losses); 
         [0024]    R×G=receiver antenna gain in dBi; 
         [0025]    R×L=receiver losses (coax, connectors) in dB. 
         [0026]    In order for a radio user to communicate when they are in a building or other structure, the radio waves must be strong enough after traveling through space to penetrate the structure of the building. Increased distance from the communications tower where the radio waves are generated can lead to weakened radio signals making it difficult for the radio waves to provide coverage inside a building. In-building coverage level (the coverage of a radio system in the interior of a building) is affected by the type of materials used in the construction of the building as well as the distance from the radio tower. Generally, the heavier the construction materials, the higher the dB level needed for the radio waves to penetrate into the structure to provide in-building communication. 
         [0027]    The National Public Safety Telecommunications Council (NPSTC) issued a Best Practices for In-Building Communications publication on Nov. 12, 2007 to provide reliable communications methods inside buildings, basements, stadiums, and tunnels. In this publication, the three primary methods for attaining In-Building Communication are: 1) utilizing additional antenna sites within a jurisdiction to increase signal level; 2) supplementing coverage in a specific building with a permanent system to boost the signal received and boost the signal transmitted to the outside; and 3) deploying a system on a temporary basis to boost coverage in a building for a specific incident scene. 
         [0028]    Increasing signal strength with additional antenna sites is typically limited by the cost, spectrum availability, approval, as well as structural obstacles preventing certain building structures from receiving adequate signal necessary for in-Building Communication. Supplemental coverage in specific buildings may add additional expense for treating each building separately and these individual systems may create problematic interference. Most importantly, permanent building specific solutions may not be reliable during an actual event at the building location. For example, a building fire may damage these systems or the antenna or power lines essential for communications. 
         [0029]    Deployable communications systems provide a practical approach to improving radio coverage and backup existing systems during an incident. Bi-directional amplifier communications systems are subject to oscillation when there is inadequate isolation (path loss) between the transmitting and receiving antenna. Because this type of oscillation can lead to serious interference disrupting other communications in the nearby area, it is illegal to operate a signal booster that oscillates and the FCC (FCC) may impose fines and confiscate equipment. 
         [0030]    According to CFR 47 Section 90.7 of the FCC, a signal booster is “a device at fixed location which automatically receives, amplifies, and retransmits on a one-way or two-way basis, the signals received from base, fixed, mobile, and portable stations, with no change in frequency or authorized bandwidth. A signal booster may be either narrow band (Class A), in which case the booster amplifies only those discrete frequencies intended to be retransmitted, or broadband (Class B), in which case all signals within the passband of the signal booster are amplified.” 
         [0031]    Under this designation, class A signal boosters are considered to be channelized amplifiers. 
         [0032]    An RF amplifier that is able to select what frequencies are to be amplified in the downlink and uplink paths and increases the RF signal strength in both directions is known as a bi-directional amplifier. 
         [0033]    Typically, the desired signal strength delivered to the facility is at least −95 dBm through at least 95 percent of the facility in non-critical areas and 99% of the facility in critical areas such as fire control rooms and exit corridors. The in-building environment should be isolated from the outside of the building to prevent detrimental oscillations. Typically, 15 dB more than the gain of the deployable communication system booster is an appropriate amount of isolation between the two inside and outside. For a 90 dB gain booster/BDA, the ideal isolation situation would be at least 105 dB of isolation for example. 
         [0034]    While the FSL is governed by the equations listed above when the wave travels through free space, when the wave encounters a solid object such as a building wall the wave can be further weakened significantly. A radio wave may lose as much as 40 dB or more in signal strength when passing through the wall of a building. Transmission of radio signals through wire or cable must also be evaluated independent of FSL. Generally, radio signal strength losses at 800 MHz frequencies, typically used in public safety radio systems, may be about 4 dB or more per approximately 100 feet of low loss type coaxial cable. The losses realized by sending radio waves through a wall via a low loss cable may be advantageous compared to the loss attributable to building wall attenuation realized when sending radio waves through thick walls as an entirely wireless transmission, especially when the former is combined with an amplifier system. 
         [0035]    U.S. Pat. No. 4,476,574 to Struven describes a method of providing multiple channels of mobile-to-mobile radio communication in tunnels, mines, buildings, and other confined spaces using radiating transmission lines. 
         [0036]    U.S. Pat. No. 4,905,302 to Childress et al. describes a method for using a trunked radio repeater system in a public service trunked (PST) system and special mobile radio (SMR) application. 
         [0037]    U.S. Pat. No. 6,032,020 to Cook et al relates to the operation of multiple repeaters utilizing a single communication infrastructure as a fixture within a building to provide communications past a barrier. 
         [0038]    US Pat. Pub. No. 20060148468 to Mann relates to the field of in-building radio communication coverage enhancement utilizing a primary external antenna, an ancillary external antenna, a donor site diversity system, an internal antenna, and a bi-directional amplifier. 
         [0039]    US Pat. Pub. No. 20070099667 to Graham discloses an in-building wireless enhancement system for high-rises with an emergency backup mode of operation including a wireless base station, a backbone coupled to the base station, a plurality of coupler units connected to the backbone, a first plurality of antennas, a plurality of amplifiers connected to the backbone, a second plurality of antennas, and optionally an emergency access port coupled to the backbone. 
       SUMMARY OF THE INVENTION 
       [0040]    An In-Building Communication (IBC) System is disclosed which permits communication in underground structures such as parking garages, basements, or tunnels, tall buildings such as sky scrapers, buildings having thick walls of concrete or metal, and/or any structure which may have dead zones due to shielding of electromagnetic radiation necessary for radio communications. 
         [0041]    The SIPS-BDA (Scaleable Intelligent Power Supply—Bi-Directional Amplifier) In-Building Communication System provides a highly effective communication system to eliminate communication dead zones in buildings during emergency situations or emergency response events. The SIPS-BDA system has its own portable lightweight power supply to power a bi-directional amplifier or other type of signal booster to overcome communications barriers in buildings, tunnels, or other radio obscuring structures during emergencies or whenever radio communications coverage is required. The invention is intended to provide radio coverage enhancement during emergency events such as fire, explosion, terrorist or violence related incidents, as well as whenever public safety or other security requirements for two-way radio coverage are present such as conventions, special events, and other public gatherings. The invention includes in various combinations and configurations a completely portable coverage enhancement system including portable outdoor (donor) antenna equipment, portable indoor antenna or antenna array equipment including the use of radiating cable or other radiating distribution components, a portable, autonomously powered signal booster system, a standardizable In-Building Communication interface box or unit, and various antenna and signal booster components which are fixed and built in to the building or structure requiring coverage enhancement. 
         [0042]    In one embodiment, the invention includes: a) an outdoor antenna system attached to the building or mounted separately outside the building, b) an indoor antenna system mounted inside the building, c) a standardized, In-Building Communication (IBC) interface box mounted on the exterior of the building, and d) a portable SIPS-BDA kit. The IBC interface box may have connections to fixed antennas in the interior of the building and an antenna directed to the exterior of the building. The portable SIPS-BDA kit is connected to an outdoor antenna system and an indoor antenna system. The portable BDA may be connected to the outdoor antenna system directly or connected via the IBC interface box. The portable BDA may be connected to the indoor antenna system directly or connected via the IBC interface box. 
         [0043]    During operation, the fire department may carry the portable bi-directional amplifier (BDA) kit, which may be powered by a lithium-ion battery pack (or other battery type or independent, portable, and/or wireless energy source). The BDA may be connected to the exterior of the building when the building is experiencing an incident such as a fire, earthquake, or an act of terrorism which requires emergency and fire personnel to report to the scene quickly. When called to a building, the fire department personnel may connect their portable, lithium-ion battery powered, bi-directional amplifier (BDA) system to the building&#39;s standardized, IBC interface box on the outside of the building. Once the BDA is connected, communications between the outside and inside of the building are enabled and communication dead zones may be significantly reduced. The connection/setup time in this embodiment is estimated to be under one (1) minute, enabling communications without having to enter the building until communications between the outside and the inside of the building are established. 
         [0044]    As an additional embodiment, the SIPS-BDA system may function independent of existing communication infrastructure. In an alternative embodiment, the invention includes: a) a portable outdoor antenna system mounted outside the building or mounted facing outside the building from within; b) a portable indoor antenna system mounted inside the building; and c) a portable SIPS-BDA kit outside or inside the building. In this embodiment, a portable outdoor antenna system and/or a portable indoor antenna system may be used as a backup in place of existing infrastructure or as the sole means of coverage enhancement in the absence of existing infrastructure. In the absence of building equipment or in the event of a building equipment failure, for instance, if the indoor antenna or cabling to the antenna has been destroyed or its status is uncertain during an incident, the portable system may be used to establish or re-establish excellent communications. It does so independent of any fixed coverage enhancement system, which may be inoperable or damaged during an emergency event. 
         [0045]    The SIPS-BDA system includes a portable outdoor antenna and a portable indoor antenna. In this embodiment, the SIPS-BDA is attached to a portable outdoor antenna that is located on the outside of the building. The SIPS-BDA is placed in a suitable location in the building and is attached to a portable indoor antenna also placed in the building. 
         [0046]    In an additional embodiment, the SIPS-BDA system may function independent of existing communication infrastructure. In an alternative embodiment, the invention includes: a) an outdoor antenna system attached mounted outside the building, b) an indoor antenna system mounted inside the building, and c) a portable SIPS-BDA kit located inside the building. The system is able to provide excellent communications capabilities independent of the fixed antenna system dependent on existing infrastructure. The SIPS-BDA system includes a portable outdoor antenna and a portable indoor antenna. In this embodiment, the SIPS-BDA is attached to a portable outdoor antenna that is located on the outside of the building. The SIPS-BDA is placed in a suitable location in the building and is attached to a portable indoor antenna also placed in the building. The outdoor antenna system may also be located in the building where it may be positioned facing outside a window or other opening in the direction of a communications tower and where suitable isolation may be obtained from the other antenna also located within the building. 
         [0047]    Other examples may be used where the SIPS-BDA is used in different combinations with the interface box and the indoor set-ups discussed above. 
         [0048]    One aspect of the system is the reduced expense and increased flexibility in comparison to fixed building treatments. The community fire department may own one or more of the SIPS-BDA portable kit(s) which can serve any number of buildings due to the standard IBC interface box on the building and standard connection to the SIPS-BDA portable kit. In addition, the SIPS-BDA portable kit may be used separately from the interface box. The SIPS-BDA portable kit may also be used by bringing it into any building upon the fire department&#39;s arrival at an event to provide effective In-Building Communication coverage when the fixed communication infrastructure connected to the IBC standard interface is damaged or not working properly. 
         [0049]    In this embodiment, the SIPS-BDA can be brought to a building experiencing an emergency by fire, emergency medicine, police, or rescue personnel to ensure communications between the inside and outside of a building regardless of the condition of the site power or communication infrastructure.

The portable amplifier kit  101  has an AC/DC output connector  109 A in the upper right portion of the amplifier kit which acts as a port allowing line power input from outside the amplifier kit into the kit. Line power input which enters the kit through  109 A is then received by AC/DC conversion module for AC input  171 A which is able to convert an AC input to a DC power output. Underneath the AC/DC output connector is a DC/DC input connector  109 A which is able to receive power from a DC source such as a vehicle or solar panel. Once a DC input enters the amplifier kit from  109 A it is routed to a DC/DC conversion module  171 B which is able to convert the power to a level of DC power which can be more effectively utilized in the amplifier kit. Both the AC/DC conversion module for AC input  171 A and the DC/DC conversion module for DC input  171 B are connected to a common line which has a connection to a DC/AC inverter module  171 C. This inverter module  171 C has a connection to the bi-directional amplifier  141 B to provide power to the BDA. The common line which interconnects the AC/DC conversion module  171 A for AC input, the DC/DC conversion module  171 B for DC input, and the DC/AC inverter module  171 C to power the bi-directional amplifier together extends further to interconnect to the DC/AC inverter module  171 D convenience AC output power and an energy subsystem rack interface  172 . The DC/AC inverter module  171 D connects to an AC/DC output connector  109  on the outside of the amplifier kit which is able to provide convenience AC output power to devices located where the amplifier kit is deployed. The amplifier kit is able to act as a wireless portable energy source at a site providing power in the event of an energy outage at the location in need of communication enhancement, or to reduce the need for extension cords increasing safety and reducing response time when using the amplifier kit. In this way, the amplifier kit may significantly lighten the load for an emergency responder providing a faster response time. 
         [0219]    Adjacent to and interconnected to the DC/AC inverter module  171 D is an energy subsystem rack interface  172 . The energy subsystem rack interface  172  is connected to the energy subsystem rack  140 R which houses individual battery energy modules  140 B. The energy subsystem rack interface  172  labeled ESS Interface manages power received from these battery modules, from the AC/DC conversion module  171 A, DC/DC conversion module  171 B, DC/AC inverter module  171 C, and DC/AC inverter module  171 D and the power interchanged between these different power modules and/or power sources. Both the BDA  141 B and the AC/DC output connector  109  can receive power from the battery modules through the energy subsystem rack interface  172 . The BDA  141 B and the AC/DC output connector  109  can receive power from a line power input, vehicle, or solar panel input (power sources from outside the amplifier kit) or from the battery modules  140 B (power source located inside the amplifier kit) located in the energy subsystem rack  140 R. The ESS interface  172  has intelligence in the form of at least one controller to manage power effectively and direct power to provide optimum energy storage capacity in the battery modules  140 B stored in the energy subsystem rack  140 R. The ESS interface  172  follows a predetermined series of steps to manage power optimally to the BDA  141 B, convenience power input  109 , converter modules  171 A,  171 B,  171 C,  171 D, and the battery modules  140 B. The ESS interface  172  follows a predetermined series of steps to manage power optimally from the line power input, vehicle or solar panel input, converter modules, and the battery modules. The predetermined series of steps optimally manages power based on the temperature, environmental conditions, performance requirements of the BDA, performance history of the batteries, and other conditions required by the application. The predetermined series of steps to optimally deliver energy can be programmed based on the energy source in the battery modules. Additional information on the process steps is found in U.S. patent Ser. No. 11/672,853, having a file date of Feb. 8, 2007 which is hereby incorporated by reference. 
         [0220]    The amplifier kit  101  includes a scalable intelligent power supply which can receive, store, and deliver power from a variety of sources. A variety of methods and circuitry to interconnect the circuitry within the amplifier case may be used. Pulse width modulation is one preferred method for managing power from a variety of inputs. 
         [0221]    The battery modules  140 B each are individually connectable and removable to and from the energy subsystem rack  140 R. Each of the battery modules has electrical connections to the energy subsystem rack  140 R which in turn is connected to the ESS interface  172 . The ESS interface can measure and control the state of charge, power, and energy storage within each battery on an individual battery module basis. The energy subsystem rack  140 R has electrical connections interconnecting the battery modules to each other and allowing them to share power to balance their state of charge for optimum energy storage or power delivery. Individual batteries may be removed from the energy subsystem rack  140 R without interrupting or interfering with the power to any of the other components in the device. Individual batteries may be inserted into the energy subsystem rack  140 R without interrupting the power to any of the other components in the device. As a result, the amplifier kit has an uninterruptible, hot swappable power supply. The power supply in the amplifier kit may be able to provide power to the BDA  141 B or convenience power output  109  with all or none of the battery modules engaged into their respective slots in the energy subsystem rack  140 R. Preferably, the battery modules  140 B have sufficient energy to supply the BDA  141 B with at least 12 hours of continuous run-time. 
         [0222]    The battery modules  140 B may also have their own intelligence in the form of controllers programmed with a series of steps to provide optimum energy storage or power delivery. Power may be received from the batteries in a sequential, proportional, alternate, step wise, or all-or-nothing manner based on the series of steps programmed in each battery module taking into account the power requirements for each application and environmental conditions. Additional information on the process steps is found in U.S. patent Ser. No. 11/672,853, having a file date of Feb. 8, 2007 which is hereby incorporated by reference. 
         [0223]    The batteries have an effective energy density, so that the amplifier case remains light-weight to be carried by one person quickly with at least 12 hours of continuous run time for the bi-directional amplifier. In one embodiment, the energy source of the battery modules are lithium-ion cells have a very high energy density allowing the amplifier kit to remain lightweight and portable and provide continuous power sufficient to operate the bi-directional amplifier for at least 12 hours. In addition, less battery modules may also be supplied if a line power is available or shorter battery run time is allowable. Optionally, more battery modules may be supplied if longer battery runtime is desired. The battery modules may all have the same energy source or different energy sources. In particular, battery modules having the same lithium-ion cells with same cell structure may be used or different lithium cells may be used within the battery modules used in the same energy subsystem rack  140 R. 
         [0224]    The batteries are interoperable with other portable equipment that may utilize a portable energy source. In particular, the batteries may also be used to supply power to portable radios, repeaters, lights, cameras, vehicles, hand tools, telephones, amplifiers, computers, medical equipment, electric equipment, inverters, or alarms which may be used at the site of an event in the case of a power outage. The lightweight high energy density of the power supply provides an important versatility advantage by being able to power other equipment. The power supply is self-contained within the amplifier kit and easy to carry, transport, and ship. Cords for transmission of power or Internet connectivity are not essential. 
         [0225]    The safety, reliability, and utility benefits of the amplifier kit are significant. The batteries may power other equipment while they remain in the amplifier kit or by being removed from amplifier kit. More information on the battery modules and charging mechanisms are found in U.S. patent Ser. No. 11/672,853, having a file date of Feb. 8, 2007 which is hereby incorporated by reference. 
         [0226]    The portable amplifier kit  101  holds the bi-directional amplifier  141 B which is connected via an outdoor antenna cable  121  to an outdoor antenna  122  aimed at a radio site. The bi-directional amplifier  141 B is connected via a cable  141 C inside the amplifier kit to an indoor cable short segment  121 B outside of the amplifier kit which is connectable to an indoor antenna system. 
         [0227]    The amplifier kit is also connected to a management gateway  176  which connects the amplifier kit to a wireless Internet Protocol (IP) network  177 . The power supply of the amplifier is accessible remotely over the Internet. The energy content of the batteries as well as the overall power supply of the amplifier kit may be monitored remotely using a standard web browser interface program. The remote web monitoring of the power status of the amplifier kits enables a single individual to monitor more than one kit and efficiently attend to the interchange of battery modules or other power sources as necessary in a multiple system deployment using more than one portable enhancement system. In one embodiment, the amplifier kit has a specific IP address assigned to it that is accessible by at least one user to monitor the power supply and run time available based on the energy content and energy inputs in real time. 
         [0228]    Further, important controls such as on/off power would also be accessible and controllable remotely providing quick communication enhancement as necessary for intermittent problems. Additionally, in the event of problematic oscillation or other forms of interference the BDA may be easily powered off through this remote access feature. In the event this amplifier kit were deployed in a larger multiple system deployment with one or more units which may be susceptible to cause interference, any unit may be powered off or on remotely as needed or desired to diagnose the best possible location to provide enhanced coverage and reduced likelihood of interference from a variety of locations. 
         [0229]      FIG. 2  is a flow chart  200  showing a method for deploying portable radio coverage. In step  201 , arrival at scene with portable coverage system occurs. A tentative location for the outdoor antenna  122  of the antenna kit  102  is selected in step  202 . A portable radio is used to perform a coverage check at the tentative location in step  203 . The results of the check are obtained in step  204 . If coverage as checked with the portable radio is not adequate at this location (negative result), the set up requires an additional testing step in step  205  to try an alternate outdoor location. In the negative result pathway step  203 , perform check using portable radio, is then repeated. 
         [0230]    Once an acceptable check result is obtained, the step  206  of laying the portable antenna kit aimed at structure entry is performed. This is depicted graphically in  FIG. 1E . Tripod legs are extended in step  207  as depicted graphically in  FIG. 1F . The tripod is stood upright with the cable organizer aimed at structure entry in step  208  as shown in  FIG. 1G . A grid map  300  at tripod base is oriented to the North using a compass in step  209 , also shown in  FIG. 1G .  FIG. 1H  depicts the following steps: The top and bottom cable retention straps are removed in step  210 . The donor antenna is aimed at a selected radio site in the next step  211 . The portable amplifier kit is placed near the tripod based in step  212 . In step  213 , the donor antenna cable is connected to the amplifier outdoor antenna port. The indoor antenna cable is connected to the amplifier indoor antenna port  214 . Although not shown explicitly as a step in  FIG. 2 , the telescoping sections of the tripod stand can also be raised to increase the height of the outdoor antenna if desired at this point. As part of step  215 , the amplifier power button is held for at least 2 seconds for delayed startup of the bi-directional amplifier. The duration of the time delay is preconfigured by software and stored in nonvolatile memory of the onboard amplifier kit microcontroller. It will typically range from several tens of seconds to several minutes depending on user requirements. The indoor antenna is pulled from clips securing it to the spine of the cable organizer and the indoor antenna is carried into the structure. Optional step  217  includes extending indoor antenna distance from the amplifier with additional cable segments. Optionally, an extended antenna kit may be inserted and taken further into the structure. Use of extended antenna kit(s) allow additional indoor antennas to be coupled and enabled creating a distributed antenna array as deployment progresses. As part of step  219 , the indoor antenna is ultimately positioned near the center of coverage area or in location to provide optimal coverage of the area in need of coverage enhancement. In some cases, it may be advantageous to select a location for the indoor antenna that is out of the way of traffic or above an area that has not yet been cleared for passage. The intelligence embedded in the amplifier kit enabling the turn on delay is activated by holding down the button provides safer, more effective operation of the BDA and communication coverage enhancement by reducing the opportunity for oscillation and resulting radio system interference due to their being inadequate isolation between the sending and receiving antennas until the indoor antenna has been taken some distance away from the outdoor antenna and into the attenuating structure. 
         [0231]      FIG. 2A  is a flow chart  200 A showing a method for deploying portable radio coverage. Initially, the power button  106  is pressed in step  201 A. The power button is held for less than 2 seconds as part of step  202 A, the power button is released as part of step  203 A, and the amplifier kit is ready without delay to operate in step  204 A. This series of process steps may be used once the amplifier kit, the outdoor antenna, and the indoor antenna, are all set up and connections to the cables connecting the amplifier kit and the outdoor antenna and the indoor antenna have all been made. The amplifier kit has storage capability to use a different process to power the BDA corresponding to different methods of actuating the power button switch. This variety of start-up sequences helps to provide effective coverage enhancement, while avoiding and reducing the opportunity for oscillation or other problematic sources of interference. A variety of different methods of actuating the power to the BDA may be used including pressing the power button in a specific sequence, holding the power button, etc. A variety of button configurations may be used on the outside of the amplifier kit. In a preferred embodiment, a button is used on the outside of the case and a variety of different start-up sequences may be initiated by using a single power button. The power to the controller intelligence in the amplifier kit may be enabled independently of powering on the amplifier in order to access important diagnostic information, while preserving battery life and reducing potential for interference. In one embodiment, the intelligence embedded in the amplifier kit and activated by holding down the button for less than two seconds. In another embodiment, the BDA may be powered up immediately to more quickly provide communication coverage enhancement more quickly based on the particular site configuration. 
         [0232]      FIG. 2B  is a flow chart  200 B showing a method for deploying portable radio coverage. A method for deploying portable radio coverage is shown in which the BDA can be powered up with a delayed start. This delay start is actuated with a single button. Further, the delay start option can be communicated using an indicator light on the outside of the amplifier case. The delay start provides the opportunity to operate the BDA safely and effectively and establish communications quickly with minimal instrumentation while avoiding problematic oscillation or automatic shutdown of the BDA. The operator can choose the best timing sequence for powering the BDA based on the conditions on site. Multiple powering sequences can be used and can be actuated simply using an amplifier kit with the same configuration and instrumentation. In all scenarios, the BDA has embedded intelligence to respond with the proper start-up and power sequence. 
         [0233]    In step  201 B, the power button  106  is pressed. The power button is held for more than 2 seconds in step  202 B. The indication that the power sequence has been started is provided with the green light illuminating in step  203 B. This start-up sequence is further actuated with the power button being released after less than 5 seconds has elapsed in step  204 B. A green light flashes for time delay start in step  205 B. The amplifier kit now may be operated as part of step  204 A. 
         [0234]    Holding the power button more than 2 seconds powers up the amplifier kit and the embedded intelligence. Once the amplifier kit is powered up information may be received from the amplifier kit intelligence by providing another command with the power button. In this embodiment, releasing the power button before 5 seconds has elapsed initiates a delay start-up mode. The embedded intelligence of the amplifier kit communicates that the delayed start-up mode has been initiated by flashing the green light. 
         [0235]      FIG. 2C  is a flow chart  200 C showing a method for deploying portable radio coverage. In step  201 C, the power button  106  is pressed. In this embodiment, an additional alternate start-up mode is initiated once the power of the amplifier kit has been turned on. This alternate start-up sequence is initiated by holding the power button down more than 2 seconds in step  202 C. The green light illuminates in step  203 C. Step  204 C includes the operation of continuing to hold the power button more than 5 seconds. In step  205 C, the green light goes out indicating the BDA in the amplifier case is not powering on, however, the intelligence in the amplifier case is powered on. In step  206 C, the power button is released. The red light on the outside of the amplifier case flashes showing state of charge in step  207 C. Indication of safe shipping status is provided in step  208 C with the illumination of the green light. Step  209 C is a step in which waiting occurs before the next button push. 
         [0236]    In this embodiment as shown in view  200 C of the flow chart, information on the energy level of the batteries is provided with the actuation of a single button. Further, important safety information is also communicated to the outside of the box from inside the box utilizing the intelligence embedded in the amplifier case and connections to the battery modules in the inside of the case. The case does not need to be opened and safety mechanisms of the battery are easily reported as functioning or non-functioning without requiring lengthy inspection. 
         [0237]      FIG. 2D  is a flow chart  200 D showing a method for deploying portable radio coverage. In addition to alternate start-up sequences, the intelligence in the amplifier kit also provides important information during operation of the amplifier. Step  204 A, the amplifier case begins operation. Green light  106  illuminates steadily in step  201 D. In an alternative embodiment, the green light illuminates mostly steadily, momentarily flashing off then quickly on again, simulating a heartbeat as an indication of normal, active operation status. The portable amplifier kit  101  is operating in step  202 D. An indication of operational status is provided by a red light  107  and a green light  106 . In the event, the red light is not flashing in  203 D, evaluation by the operator may continue to examine the green light  106  in  208 D. In the embodiment, where the green light  106  is not flashing, the portable amplifier is operating  202 D. However, in the embodiment the green light is flashing slowly with equal on and off times, the intelligence of the amplifier kit is communicating a low battery warning  212 D. The portable amplifier kit may continue to operate in step  202 D. 
         [0238]    However, in the event following  202 D, single flashes are being produced by the red light  107  as in  204 D, a Warning-Error 1 (e.g. AGC operating)  209 D is provided. Following warning  209 D, the portable amplifier kit  101  is operating as shown in  202 D. 
         [0239]    During operation of the portable amplifier kit  101  in  202 D if a red light  107  is flashing  203 D an evaluation step for double flashes  205 D occurs. In the event of an affirmative response to the double flash evaluation step  205 D, a Warning Error 2 (e.g. isolation failure) is indicated in  210 D. The portable amplifier kit  101  is operating as shown in  202 D. 
         [0240]    Following operation of the portable amplifier kit  101  in  202 D an evaluation for red light  107  flashing  203 D takes place. A positive result for triple flashes indicates a Warning Error 3 (e.g. overload shutdown) by  211 D. The suspension of the amplifier operation  213 D may then occur. A system error following triple flashes is provided by  207 D. 
         [0241]      FIG. 3  is a view  300  of a regional radio system grid map  300  identifying several alternate radio system site locations  303 ,  304 ,  305 ,  306 ,  307  in proximity to a particular location requiring radio coverage enhancement  302 . The regional radio system grid map  300  has a North direction indicator  301 , longitude indications  309 , latitude indications  310 , and all the radio system site locations identified over the entire county region  308 . The map also provides the direction to aim outdoor antenna  311  to communicate with the preferred radio system site location  303 . This directional indication would be provided specific to each site. Each site has a specific plot that is stored in a location accessible by the personnel using the antenna kit and the amplifier kit. 
         [0242]      FIG. 3A  shows a flow chart  300 A for aiming the outdoor antenna. Initially, the latitude and longitude of location  302  is established in step  301 A. Location  302  is identified on the map  300  in step  302 A. North direction  301  at the location  302  in need of communication coverage enhancement is determined in step  303 A. Based on topography of the area surrounding location  302 , the building location, entrance location, infrastructure, emergency concerns, evacuation routes, equipment limitations, optimal location for cable length, and to reduce the amount of time to enter building to establish communications, the preferred radio site  303  is determined  304 A. The map  300  is then oriented with north aligned beneath tripod  100 G in this step  305 A. In this step  306 A, the antenna  122  is aimed in the direction of the radio site  303 . The antenna elements  122 A are checked for alignment and correctly oriented (e.g. vertical in the case of a Yagi directional antenna) as part of this step  307 A. The remaining components of the coverage system are deployed and the coverage system is enabled during this step  308 A. 
         [0243]    A check may be performed using a portable radio to confirm that coverage has been enabled in step  309 A. In one test, a first portable radio may have its portable antenna removed. The first portable radio attempts to transmit to a second portable radio. (The amplifier&#39;s power is off during this test). Once an error message is received by the first radio indicating that the signals to a second radio cannot be received, the amplifier is turned on. At this point, the first radio should attempt to transmit a signal to the second radio. The signal from the first radio to the second radio should be able to be received once the amplifier has been turned on. Another suitable test procedure could be used in place of this method to test the system quickly. 
         [0244]    The results of the check are evaluated as part of step  310 A. If the results of the test are positive, the system is providing coverage in step  310 A. If the results of the test are not positive, an alternate radio site (e.g.  304  is determined in step  312 A and steps starting with the aiming of the directional antenna step  306 A in direction of the radio site  303  are repeated in sequence until a positive result for step  310 A is obtained. 
         [0245]    The system can establish communications rapidly through quick deployment and a simple set up configuration. The set up has simple orientations to ensure reliable set up with accuracy. Additionally, the set up can take place with a single person. The set up may also use a database of preferred radio sites instead of a regional grid map identifying the preferred local radio sites. 
         [0246]      FIG. 4  shows a view of typical system deployment  400  for building coverage enhancement at a location requiring radio coverage enhancement  302  at a building  401  having multiple floors. The portable antenna kit with the outdoor antenna raised  100 J is located outside the building  401  on the ground  402  at the geographic location requiring radio coverage enhancement  302 . The building  401  has a roof  403 , windows  405 , ground floor  407 , interior doorway seen through window  404 , and an exterior wall  419 . The building has floors second  408  through seventh  413  which are considered as part of the system deployment. 
         [0247]    Based on the regional radio system grid map  300  or the operator&#39;s own understanding of geography, the antenna kit may be oriented towards the building entranceway to dispense cable most safely and effectively. After orienting the gridmap  300  in the northward direction  301 , the regional radio system grid map  300  is used to determine the direction to aim outdoor antenna  311 . The outdoor antenna is aimed in the most acceptable line-of-sight path to the preferred radio system site location  303 . The double ball joint on the amplifier kit may be useful in orienting the antenna boom in the proper direction  311  while simultaneously aligning the vertical elements coincident with the vertical plane. 
         [0248]      FIG. 4A  shows a closer perspective view  400 A of a typical system deployment for building coverage enhancement at a location requiring radio coverage enhancement  302  (a building  401  having multiple floors). A closer view of a typical system deployment for building coverage enhancement  400 A shows the outdoor antenna raised  100 J and connected with an outdoor antenna cable  121  to the amplifier kit. The tripod has a telescoping section  135  which is in raised position. The antenna kit is also connected to the amplifier kit with a short segment of an indoor antenna cable  121 B. The long segment of the indoor antenna cable  132  leads into the main entrance door  415  of the building  401 .  121 B and  132  are segments of an otherwise continuous cable connecting the amplifier with the indoor antenna. 
         [0249]    The regional radio system grid map  300  is shown on the ground with the top of the map aligned to correspond to the North direction indicator  301 . The direction to aim outdoor antenna  311  is also provided on the map  300 . The boom of the outdoor antenna is aimed to point in this direction  311  toward the preferred radio system site location  303 . The vertical elements of the boom are aligned to be perpendicular to level ground. 
         [0250]    In this closer perspective view of the building  401 , in addition to the ground floor  407 , second floor  408 , third floor  409 , fourth floor  410 , fifth floor  411 , sixth floor  412 , and seventh floor  413 , and a roof access door  414  are shown from this view on the roof  403 . 
         [0251]      FIG. 4B  shows an enlarged view  400 B of portable antenna kit and portable amplifier kit deployed at a location requiring radio coverage enhancement  302  at a building  401  having multiple floors. The enlarged view  400 B of a portable antenna kit and amplifier kit deployed by building  401  illustrates the portable antenna kit with the outdoor antenna raised  100 J. The outdoor antenna is at the end of the raised telescoping section of the tripod  135  and the antenna is more clearly seen to be in communication configuration (elements of the boom are vertical or perpendicular to level ground). The outdoor antenna cable  121  is connected to the outdoor antenna and amplifier kit. A short segment of indoor antenna cable  121 B connects the antenna kit to the amplifier kit. A long segment of indoor antenna cable  132  leads from the antenna kit over the ground  402  onto the ground floor  407  of the building  401  through the main entrance doorway  415 . The location requiring radio coverage enhancement  302  is illustrated with the essential components of the outdoor components deployed outside the building  401 . 
         [0252]      FIG. 4C  shows a cut away view  400 C of a cable from the antenna kit to the indoor antenna coverage location. The cut away view of a cable connecting the antenna kit to the indoor antenna coverage location  400 C provides a view of the long segment of the indoor antenna cable  132  extending from the antenna kit (which is located outside the building on the ground) on the ground floor to the fourth floor in an upwards direction  418  in the stairwell  417 . The cable  132  may proceed straight up along the stairwell wall  416  past the ground floor  407 , the second floor  408 , third floor  409 , and ending on the fourth floor  410 . In this way, less cable is used in this vertical path of the cable and less cable is placed on the path of travel on the stairs  417 . In an alternative embodiment, the cable may be placed along each step on the stairway and across the midfloor landing  420 . However, this path may require more cable to be used. Based on the specific area of the building requiring communication coverage enhancement will require the best available path to deploy the cable to provide the desired pattern of communication coverage enhancement. Optionally, an extended antenna kit or kits may be used to place incremental indoor antennas along the path to an ultimate or terminal indoor antenna location thus creating a distributed antenna array effecting coverage over a wide internal area of the building. 
         [0253]    The indoor antenna  133  and long segment of the indoor antenna cable  132  are ultimately located on the fourth floor  410 . The antenna  133  may be suspended from cable  132  draped over a door or edge, or mounted using various accessories standing on the floor or table or hung from an overhead fixture as shown later in  FIGS. 12, 12A, 12B, and 12C . Communication coverage enhancement may be provided to floors adjacent based on the coverage of the indoor antenna and the building construction, materials, and other environmental conditions. For example, coverage on the fifth floor  411  may be enhanced, while the indoor antenna is located on the fourth floor  410 . In this way, coverage may be provided to floor that is not yet secure without requiring communication personnel to step foot on the unsecured floor. Directional versus omni directional antennas may be selected for this very purpose such as the patch or Yagi antenna shown in  FIGS. 11B and 11C . Such antennas will concentrate more signal energy in the particular direction they are aimed such as upper floors  5  through  7  if aimed upward from floor  4 . 
         [0254]    Based on the area of the building requiring communication coverage enhancement, the configuration will be determined for the location requiring radio coverage enhancement  302 . In particular, windows  405  located throughout the building may also be used to establish communication coverage enhancement. The technique of placing the outdoor antenna and/or amplifier kit indoors aimed out windows may be used to reduce the path of cable traveling through the building. In one embodiment, the cable could lead directly from the outdoor antenna kit outside on the ground up the side of the building and in through a window on the particular floor in need of coverage enhancement. This may be used based on the building configuration, material construction, access to the building, available equipment (i.e. ladder and available length of cable), configuration factors such as isolation, coverage areas, access to the building as well as time. 
         [0255]    Based on the area requiring communication, the outdoor antenna may be located inside and pointed in the direction of the preferred radio system site location  303  through a window. In this alternate configuration, the building&#39;s internal structure may be used to provide isolation between the indoor antenna and outdoor antenna. Since elements of the this communication enhancement invention are portable, a variety of configurations are possible and may be used to enhance communications including configurations where the outdoor antenna, the indoor antenna, and the amplifier kit may all be located inside the building, outside the building, or any combination. The amplifier kit and the antenna kit are portable and can be set up in a variety of configurations to overcome communication obstacles. 
         [0256]    In another embodiment, the cable  132  used in the area needing communication coverage enhancement may be a type of coaxial cable referred to as “leaky coax” and may be used to provide radio coverage to an increasingly distributed coverage area. In one embodiment, the leaky coax may extend vertically as shown in the drawing or it may used to lay horizontally over the stairway and midfloor landing. In one embodiment, a portion of the cable ( 132 ) may be a type of low loss coaxial cable and another portion of the cable ( 132 ) may be a type of leaky coax. In one embodiment, the leaky coax portion of the cable ( 132 ) may be used at an end portion of cable ( 132 ) in place of an indoor antenna ( 133 ). Preferably, the portion of the cable ( 132 ) which is shown to bypass the exterior wall or other source of radio signal attenuation will have as little loss as possible. In another embodiment, a low loss coaxial portion may lead to a directional coupler or splitter, where two separate cables extend from said coupler one being an additional portion of low loss coaxial cable and another portion being a leaky coaxial cable portion. Many other combinations and permutations may be readily implemented. 
         [0257]      FIG. 4D  shows a view  400 D of the indoor antenna location deployed at the fourth floor of building requiring radio coverage enhancement  302 . The indoor antenna location on the fourth floor of building  400 D shows a closer view of the indoor antenna  133  connected to the long segment of the indoor antenna cable  132  on the fourth floor  410 . The cable  132  is illustrated extending in an upward direction  418  and laying across a portion of the stairs  417  on the fourth floor. The indoor antenna is located just outside the stairwell doorway  421  and may be variously supported or mounted as described above. 
         [0258]    As mentioned previously, this location of the indoor antenna near the fourth floor stairwell doorway could also be achieved through a variety of configurations. Alternatively, the cable could extend in an upward direction from the antenna kit on the ground floor and enter the building through a window. Alternatively, the outside antenna and/or the amplifier kit could also be located in the building. In another configuration, the outdoor antenna could be located inside the building and pointed out of a window or other entranceway or portal. In yet another embodiment elements of the system including the outdoor antenna and amplifier could be located on the roof of the building  403 . 
         [0259]      FIG. 5  is a view  500  of a vehicle borne portable radio enhancement system.

The antenna kit at the bottom rests on a rotating portable antenna kit mounting platform  506 . A rectangular portion of the cable organizer can be seen inside the coil of wound cable. The indoor antenna  133  is securely attached to the spine  125  of the cable organizer on the inside of the wound cable. A pigtail cable  132 A can be seen attached to a bottom portion of the indoor antenna. It should be noted that the antenna stand may be quickly removed from the vehicle if needed by simply releasing retaining strap  504  and lifting the entire kit up and off of platform  506 . Once removed, the antenna system may be portably deployed as described in previous paragraphs. 
         [0267]      FIG. 5C  shows a view  500 C of the portable amplifier kit mounted on an emergency response vehicle in the vehicle borne portable radio enhancement system. The bottom of the portable amplifier kit  101  is seated in a portable amplifier kit bin  502  on the back of an emergency response vehicle. A portable amplifier kit retention strap  503  spans across the top of the amplifier kit and holds the amplifier kit against the emergency response vehicle. The door  101 D of the portable amplifier case is in closed position with the hinge side of the amplifier case running from top to bottom on the left side of the amplifier kit. The outdoor antenna cable  121  connects to the outdoor antenna connector port on the top right of the amplifier case. The short segment of the indoor antenna cable  121 B is connected to the indoor antenna connector port adjacent to the outdoor antenna connector port on the top right of the amplifier case. The two cables extend alongside each other from the top of the amplifier case to a position to the left of the bottom of the amplifier case. It should be noted that the amplifier kit may be quickly removed from the vehicle simply by releasing retaining strap  503  and lifting the amplifier kit up and out of bin  502 . Once removed, the amplifier kit may be portably deployed as described in previous paragraphs. 
         [0268]      FIG. 5D  is a view  500 D of the vehicle borne portable radio enhancement system in the deployed configuration. The portable amplifier kit  101  is secured on one end of the emergency vehicle with a portable amplifier kit retention strap  503  spanning across the top of the amplifier kit and the bottom of the amplifier resting in a portable amplifier kit bin  502 . Cable clamps  505  secure the cables leading from the amplifier along a bottom portion of the emergency response vehicle. The outdoor antenna cable  121  and the short segment of the indoor antenna cable  121 B lead from the amplifier kit until reaching the left most cable clamp  505 . From this leftmost cable clamp near the bottom of the emergency response vehicle, the outdoor antenna cable  121  extends upward connecting to the outdoor antenna  122 . The short segment of the indoor antenna cable  121 B leads back to the antenna kit. 
         [0269]    The outdoor antenna is located at the top of an outdoor antenna mast in a position above the emergency response vehicle  501 . A top portion of the portable antenna kit is secured to the back of the emergency vehicle with a portable antenna kit retention strap  504 . The adjustor for the second telescoping section  123 C and the adjuster for the first telescoping section  123 B are turned to extend the antenna mast into an elevated position and then locked into place. The long segment of indoor antenna cable  132  is deploying from cable organizer  520  and headed for the building ingress as both the upper cable retention strap  130  and the lower cable retention strap  130 B are unattached from the cable organizer allowing the cable connected to the indoor antenna  133  to deploy. 
         [0270]    The rotating portable antenna kit mounting platform  506  is turned slightly away from the rear of the emergency response vehicle in a fashion to align the cable organizer in the direction of the building ingress so that cable  132  pays out easily as indoor antenna  133  is transported to and into the building. 
         [0271]    Many alternative attachment locations and mechanisms for both antenna system and amplifier system on many different types of vehicles are possible and contemplated to all be part of this invention. For example, the components could be mounted to either side, the front, or the top of a truck. A helicopter could also be used to mount and deliver the equipment to a coverage enhancement scene. The system could be mounted on a stationary structure such as a maintenance outbuilding, safely removed from the structure requiring coverage where it would not be damaged in the event of a disaster in that building, but also quickly detachable and deployable in a fully portable way. 
         [0272]      FIG. 6  illustrates a view  600 A of a schematic of a hybrid system with standard interface box. The built-in outdoor antenna  622  is mounted on the building roof  403  preferably using a non-penetrating antenna system  632 . Concrete block or sand bag ballast may be used to mount the non-penetrating roof stand  691  and non-penetrating roof stand base  692  on the roof  403 . Alternatively, an existing building mast or other attachment point may be utilized. The built-in outdoor antenna  622  is a Yagi directional antenna and will be aimed at a tower located in a preferred proximity or orientation with the closest and most unobstructed path. Consideration of other radio systems such as cellular or private radio systems should also be considered when selecting the outdoor antenna location and orientation. Other antenna types and configurations may be used. A panel antenna may also be used. Coaxial cable shield is to be grounded via 6 AWG cable with appropriate weatherproofing at the connection point to the coaxial cable. Coaxial cable  610  extends from the roof top antenna system down the building to the interior wall space directly adjacent to the In-Building Communication (IBC) Interface Box where the cable  610  connects to the rear antenna port  603  on the standard building interface box  601 . The low loss coaxial cable  610  connects the antenna to a rear antenna port  603  inside of the interface box  601 . A surge suppressor  624  is located inside interface box between the outdoor antenna connection port  618  and the rear antenna connection port  603  protecting the outdoor antenna cable system and building systems in the event of a lightning strike. The surge suppressor has a robust ground connection via terminal  630 , conductor  605 , and ground stake  606 . 
         [0273]    The standard building interface box  601  may also be referred to as an emergency radio coverage system access panel, in building communications interface, communications panel, interface box, and other combinations thereof. The outdoor antenna system  632  is now accessible through the outdoor antenna connection port  618  of the interface box  601  which is located on the exterior wall  419  of the building at a ground level location conveniently attended by first responders entering the building. In this embodiment, the outdoor antenna system is accessible to the emergency response personnel behind the door  621  of the interface box  601 . Authorized access to the panel is enforced by a lock  602  or other securing to prevent access to the panel by unauthorized personnel. Preferably the panel would allow emergency personnel or authorized personnel to establish communications status without entering the building. Other locations may be used which are easily accessible to fire, other public safety, or building premise personnel. 
         [0274]    Still referring to  FIG. 6 , the built in indoor antenna  633  will typically be positioned at a ceiling height near the center of the building or other suitable position in the building to provide coverage enhancement as needed. The small, lightweight antenna  633  may be connected via a magnetic base to a suitable steel structure or drop strut of the ceiling  640 . Other suitable fasteners, clamp, adhesive backing, Velcro-type hook and loop, and other securing mechanisms may be used to connect to the antenna to a structure inside of the building. Low loss coaxial cable  609  connects the indoor antenna  633  to the indoor antenna rear port  604  on the in-Building Communication (IBC) Interface box through holes in the exterior wall  419 . The indoor antenna system  631  is now accessible through the front antenna connection port  617  of the interface box which is located on the exterior wall  419  of the building at a ground level location easily accessible to fire and other public safety personnel. A ¼ 20 ground terminal  630  along with ground stake  606  and 6 AWG cable  605  are provided for earth grounding near the box location. 
         [0275]      FIG. 6A  provides a schematic representation  600 A of a hybrid system with the portable amplifier kit connected to the outdoor antenna system. As before, the built in antenna systems are pre-configured and connected to the IBC Interface Box. The IBC Interface Box  601  has the security lock (not shown) removed and front door in open position (not shown). The IBC Interface Box  601  is connected via a coaxial cable  612  from the indoor antenna front port on the Interface Box to the indoor antenna connector port  104  on the portable amplifier kit  101 . The portable amplifier kit  101  is connected via a coaxial cable  611  from the outdoor antenna connection front port  618  on the interface box  601  to the outdoor antenna connector port  105  on the portable amplifier kit  101 . The portable amplifier kit  101  includes: a BDA  141 , a SIPS Power and Control Module  636 , and a carrying case. The case of the amplifier kit  101  includes a power push button  106  and a status light  107  which communicate information from the SIPS power and control module  244  located on the inside of the case to the outside of the case. 
         [0276]      FIG. 6B  is a front view of the standard interface box  601  with the door  621  closed. The standard building interface box  601  may be pre-assembled and may be mounted to the exterior face of the building at a ground level location easily accessible to fire and other safety personnel. A hinge  670  is located on one side of the interface box. A cable  605  for earth grounding near the box location to an appropriate grounding mechanism is also attached to the standard interface box  601 . Mounting ears  614  or other mechanisms may be used to attach the IBC assembly to the building or structure surface. 
         [0277]      FIG. 6C  is a front view of the standard interface box with the door  621  open with a cable jumper  616  in place. The cable jumper  616  connects the front indoor antenna port in the standard building interface box  617  to the outdoor antenna front port in the standard building interface box  618 . This implements a passive coverage system which may be of some utility under certain circumstances even without a portable amplifier being connected. The inside of the door  621  includes a pocket  620  and a regional radio system grid map  300 . The door of the interface box  601  is connected to the interface box  601  by a hinge  670 . The front port of the outdoor antenna in the standard building interface box  618  eventually connects to the outdoor antenna (not shown) through various circuit elements and cables (not shown). A cable conduit  615  exits the top of the interface box as an optional route to connections at the outdoor antenna. In this embodiment, the fixed indoor antenna system interfaces directly with the fixed outdoor antenna system. In this embodiment, no portable equipment is used. The jumper is quickly removable and a portable amplifier system may be readily connected to provide bi-directional boosting of signal levels communicating between the outdoor and indoor antennas. 
         [0278]      FIG. 6D  is a front view  600 D of the standard interface box with the door open and the cable jumper removed. The interface box includes two polarized connectors on the right side of the front panel of the interface box. An earth ground cable  605  is connected to the lower right corner of the interface box  601  at terminal  630 . The indoor antenna front port  617  is located on the upper right near the top portion of the interface box. The front port  617  has a polarized surface for mating with a cable connector. The outdoor antenna front port  618  is located on the right side beneath the indoor antenna port  617  and has polarization opposite of the indoor antenna port  617 . This assures correct connection of outdoor antenna system to amplifier outdoor antenna port and indoor antenna system to amplifier indoor antenna port. Put simply, connector gender prevents misconnection. 
         [0279]      FIG. 6E  is a cut away front view  600 E of the standard interface box with the door open and with both the cable jumper and standard connector mounting panel removed.

With the standard connector mounting panel  619  (not shown) removed the cable connections between the indoor antenna, front port, standard building interface box  617  and the outdoor antenna, front port, standard building interface box  618  can be more easily observed. A cable  628  connects the indoor front port  617  on the right top portion to the indoor rear port  604  on the left upper portion of the standard building interface box. 
         [0280]    The outdoor antenna front port  618  is connected via cable  626  to a surge suppressor  624 . The cable surge suppressor  624  is connected to the outdoor antenna rear port  603  via cable  627 . The surge suppressor  624  is connected to the standard interface box via mounting and grounding bracket for surge suppressor  625 . The location of the front and rear ports are interchangeable, so long as the polarization of the connectors is maintained enabling a device on the outside of the box to be connected to the proper indoor or outdoor antenna. 
         [0281]      FIG. 6F  is a rear view  600 F of the standard interface box as it would be seen looking through the wall upon which it is mounted.

The connector mounting panel  619  of the standard interface box is shown on the front portion of the interface box having four port connections. 
         [0289]      FIG. 6M  is a view  600 M of the standard interface box for use with built-in components of the hybrid system with jumpers removed. The standard building interface box in this full built in embodiment, has a regional radio system grid map  300  inserted in the literature pocket  620  on the inside of the door  621 . An earth ground cable  605  is shown exiting the lower left of the box. Mounting flanges  614  are located on the top portion of the standard interface box. The indoor antenna front port  617  is shown on the front portion of the interface box positioned at about the same height as the built-in booster indoor antenna front port  663  also on the front panel portion of the standard interface box. The outdoor antenna front port  618  is located beneath the indoor antenna front port  617 . The outdoor antenna front port  618  is shown at about the same height as the built-in booster indoor antenna front port  662  also on the front panel portion of the standard interface box. The built-in booster indoor antenna front port  662  is located beneath the built-in booster indoor antenna front port  663 . The connector mounting panel  619  of the standard interface box is shown on the front portion of the interface box having four port openings: the built-in booster indoor antenna front port  663 , the built-in booster indoor antenna front port  662 , the indoor antenna front port  617 , and the outdoor antenna front port  618 . The ports have polarized connectors specific to each antenna or signal booster function: indoor or outdoor. Each port is polarized differently, so that the indoor antenna port and the outdoor antenna port connections cannot be misconnected. 
         [0290]      FIG. 6N  is a rear view  600 N of the standard interface box for use with built-in components of the hybrid system. The ear view  600 N of the standard interface box illustrates a rear portion of the interface box having four rear port connections: the built-in booster indoor antenna rear port  663 A will be connected to the booster indoor antenna port via a cable run not shown, the built-in booster outdoor antenna rear port  662 A will be connected to the booster outdoor antenna port via a cable run not shown, the indoor antenna rear port  604  will be connected to the indoor antenna array as previously described, and the outdoor antenna rear port  603  will be connected to the outdoor antenna system as previously described. The jumpers  651  and  652  previously shown complete the built in booster to built in antenna system circuit connections. The advantage of using the IBC Interface Box lies in the ability afforded first responders to quickly bypass and substitute portable components for malfunctioning or disabled built in components in any combination required for the IBC Interface Box located in the relative safety of the building&#39;s exterior. 
         [0291]      FIG. 6O  is a flow chart  600 O of a method for deploying enhanced radio coverage. In step  601 A, the portable coverage system arrives at the scene. The portable amplifier  101  is placed near the standard In-Building Communication interface box (IBC I/F)  601  in step  602 O. The lock  602  is unlocked and the door  621  as part of step  603 O. The indoor amplifier port  104  is connected to the IBC I/F port  617  using cable  612  in step  604 O. In step  605 O, the outdoor amplifier port  105  is connected to IBC I/F port  618  using cable  611 . As part of optional step  606 O, the IBC may be used to diagnose the building system integrity. The results of the optional check are evaluated as part of step  607 O. A No response to this check in step  607 O leads to step  609 O. However, if the result of the test is positive in  607 O, an immediate start-up procedure is initiated in step  608 O by pushing and releasing amplifier power button. 
         [0292]    However, following a no response to the check in step  607 O and reference to the literature in step  609 O. The outdoor antenna is evaluated for failure as part of step  610 O. In the event an outdoor antenna failure is identified as part of step  610 O, a portable outdoor antenna may be substituted for the building antenna as part of step  611 O. In the event, the outdoor antenna has not failed or if the outdoor antenna has filed and once a substitute antenna may be inserted, the process continues with an inspection of the indoor antenna as part of  612 O. 
         [0293]    Following a yes response for indoor antenna failure check in step  612 O, a portable indoor antenna may be substituted for the building antenna as part of step  613 O. Following step  613 O and a No response to step  612 O, the building is inspected for severe damage as part of step  614 O. If severe building damage is identified which may compromise other fixed components of the system, the stand-alone portable system deployment  200  is used in step  615 O. However, if the severe damage is not identified in response to step  614 O, the process proceeds to step  608 O where the amplifier is powered on with push and release of the power button  106  for immediate start-up. 
         [0294]    A similar process is applied in the case of the four-port IBC Interface Box full built in embodiment described above. In this case, in addition to the integrity checks of built in outdoor and indoor antenna systems, the built in booster system integrity may also be examined. If any of the built in components shows malfunction, portable components arriving safely and undamaged with first responders may be quickly substituted overcome the malfunction. 
         [0295]      FIG. 7  is a table of preparedness strategies and deployment configurations. The table describes three different types of treatment scenarios in the second column and relative investment (monetary) in terms of first responders and premise(s) in columns three and four. The configuration requirements (portable or built-in) for the outdoor antenna, amplifier, and indoor antenna are indicated in columns six, seven, and eight. It should be noted that these strategies and their respective configurations correspond variously to the fully portable deployment, the IBC Interface Box hybrid embodiment, and the IBC Interface Box full built in embodiment described in the preceding paragraphs. 
         [0296]    The first treatment strategy (Strategy #1) in row  2  of the chart indicates that a first responder can provide a completely portable communication coverage enhancement requiring no invested equipment in the premise. Configuration #1 within Strategy #1 represents a passive enhancement approach where antennas are utilized along with cabling to convey the signal past the blocking structure without the use of an active amplifier system (hence passive approach). Configuration #2 within Strategy #1 is a typical portable enhancement approach as described earlier using portable outdoor antenna, portable amplifier system, and portable indoor antenna or antenna array. Further options within these general configurations include various placements for the portable outdoor antenna, for example, outside the structure mounted on the ground or mounted on a vehicle, or inside the structure mounted to aim through a window or other opening, or upon the structure such as on a rooftop. Various placements for the portable amplifier are also contemplated including near the portable outdoor antenna, near the portable indoor antenna or array, or an arbitrary distance between the outdoor and indoor antenna. This may result in the portable amplifier being located outside the structure on the ground or mounted to a vehicle, or inside or upon the structure. 
         [0297]    The second treatment strategy (Strategy #2) adjacent to the 2 in the first column of the chart indicates that a building with installed standard interface provides configurations 3-8 (5 different configurations total) utilizing a various combinations of built-in and portable components. The installation of the standard interface box requires a moderate investment by the premises and the same investment by the first responders as the previous strategy #1. However, the standard interface box provides a number of different configuration options which can provide a flexible response to emergency conditions including back up of damaged or inadequate built-in systems. 
         [0298]    The third treatment strategy (Strategy #3) adjacent to the 3 in the first column of the chart indicates that a building with installed standard interface provides configurations 9-15 (7 different configurations total) utilizing various combinations of built-in and portable components including antenna subsystems, signal booster, backup power, and alarm system interconnected using a standard building interface. The installation of the standard interface box requires a moderate investment in the premises and the similar investment by first responders as the previous strategies. However, the installed antenna subsystem, signal booster, backup power, and alarm system require significantly more investment in the premises than the previous two types of treatment strategies. Again, the standard interface box provides a number of different configurations to utilize the installed and portable elements to provide the most effective communication coverage enhancement most quickly and flexibly at particular premises under particular circumstances. 
         [0299]      FIG. 8A  is a schematic view  800 A of the typical portable In-Building Communication enhancement treatment. 
         [0300]    A portable In-Building Communication enhancement treatment is applied to a building  801  and set distance from a radio site  803  such as a radio tower. A portable amplifier kit  804  is located outside the building  801 . The outdoor antenna amplifier port  805 B of the portable amplifier kit  804  is connected via an outdoor antenna cable  805 A to a portable outdoor antenna  805 . A portable indoor antenna  806  is placed inside the building  801 . The portable indoor antenna  806  is connected to the indoor antenna amplifier port  807 A of the portable amplifier kit  804  with a long segment of indoor antenna cable  807  and a contiguous short segment  807 A. 
         [0301]    The amplifier kit is connected to the indoor antenna and portable outdoor antenna and powered on enhancing radio communications from inside of the building  801  to reach the radio site  803  and communications from the radio site  803  outside the building to be transmitted to radio users within the building. The indoor antenna  806  and the outdoor antenna  805  are separated by a sufficient distance and structure, so that oscillation of the amplifier is precluded by adequate isolation. The amplifier kit has an automatic shutdown feature in the event oscillation or other problematic forms of interference should occur. 
         [0302]    The portable In-Building Communication enhancement treatment is simple to use and can be set up quickly which enables communication to be established with less risk to those on-site. In this embodiment, the indoor antenna is the only piece of equipment that is required to be brought into the building to provide communications. The indoor antenna can be brought into the building as part of the last step in establishing communications. 
         [0303]      FIG. 8B  is a schematic  800 B of the typical vehicle mounted portable In-Building Communication enhancement treatment. In this embodiment, all of the components of the portable outdoor amplifier kit  804  and the portable outdoor antenna  805  are mounted to an emergency response vehicle  808 . In this way assembly time can be further reduced, as less time is necessary to establish communications by deploying the portable outdoor antenna from a bag. In this embodiment, the indoor antenna is the only piece of equipment that needs to be brought inside in order to provide the portable In-Building Communication enhancement treatment. 
         [0304]      FIG. 8C  is a schematic  800 C of the typical portable In-Building Communication enhancement kit with an extension antenna kit. In this embodiment, the portable outdoor antenna  805  is located outside the building  801 . The portable amplifier kit  804  is attached to the outdoor antenna and is also located outside of the building  801 . The portable indoor antenna  806  is located inside the building  801  and is connected via an extension cable  812  to a portable extension antenna stand  809 . The portable extension antenna stand  809  is coupled to the long segment of the indoor antenna cable  807  which connects to the amplifier kit. In this embodiment, the amplifier kit may be located outside of the building. The portable extension antenna stand  809  has an extension antenna selection switch  810 , an extension indoor antenna  811 , and an extension cable  812 . Extension antenna selection switch  810  may be actuated to enable or disable signal distribution from interim extension antenna  811 . Signal will be delivered to the ultimate indoor antenna  806  regardless of the position of switch  810 . 
         [0305]    The portable extension antenna stand can provide increased reach of the portable In-Building Communication enhancement treatment with its addition of extended length of cable as well as the use of an additional indoor antenna to provide increased coverage throughout the building. A distributed antenna system (DAS) may be applied to the building quickly as part of the overall portable In-Building Communication system deployment. 
         [0306]      FIG. 8D  is a schematic  800 D of the typical portable In-Building Communication enhancement kit with an extension cable and a specialty indoor antenna. In this embodiment, the amplifier kit  804  and the portable outdoor antenna  805  are connected to each other and are located outside the building. The portable amplifier kit is connected to a specialty portable extension antenna  814  which is located inside the building  801 . The specialty portable extension antenna may be selected based on the specific handheld radios that are used as part of the system, configuration or materials used in the building construction, coverage pattern intent, or other reason specific to the circumstances and the location in need of communication coverage enhancement. 
         [0307]    The amplifier kit in this embodiment is shown connected to the specialty antenna system  814  via portable extension cable  812 , cable coupler  813 , and usual indoor antenna connection cable  807 . In this embodiment an increased connection length is used between the amplifier kit  804  and the indoor antenna  814  using a coupler  813  and cable extension  812 . The type of cable extension used can be determined based on the length of cabling required as well as other factors necessary to provide communication enhancement such as suitable isolation occurring between the amplifier kit and the specialty indoor antenna. 
         [0308]      FIG. 8E  is a schematic  800 E of a typical hybrid system including an attached portable amplifier kit. In this embodiment, the building  801  has a standard building interface box  815  attached directly to the building. The standard building interface box  815  is connected to a built-in outdoor antenna  818  and a built-in indoor antenna  819  both of which may also may be attached directly to the building. 
         [0309]    The standard building interface box  815  includes a standard building interface indoor antenna front port  816 A and a standard building interface outdoor antenna front port  817 A. The portable amplifier kit  804  is located outside the building and includes: an outdoor antenna amplifier port  805 B and an indoor antenna amplifier port  807 A. An indoor antenna port cable  816  connects the indoor antenna amplifier port  807 A of the amplifier kit  804  to the standard building interface indoor antenna front port  816 A. An outdoor antenna port cable  817  connects the outdoor antenna amplifier port  805 B of the amplifier kit  804  to the standard building interface outdoor antenna front port  817 A. 
         [0310]    In this embodiment, the amplifier kit is the only piece of portable equipment that is deployed on the scene to enable communication enhancement. The amplifier kit may be operated outside of the building. This portable set up may proceed more quickly than fully portable configurations. The outdoor antenna fixed to the building may be aimed correctly without requiring any additional orientation by the operator. In this embodiment, set up time and cost to provide a communication enhancement to the building may be greatly reduced. Maintenance costs associated with built in equipment are also optimized as it is far more economical to maintain simpler antenna and cabling systems compared to complex electronic amplifier, battery, and alarm systems. 
         [0311]      FIG. 8F  is a schematic  800 F of a hybrid system including a portable amplifier kit bypassing a failed built-in outdoor antenna  818 . Perhaps antenna system  818  was damaged by fire, explosion, or weather related phenomena. Alternatively, the radio site at which antenna  818  was aimed in fixed fashion at time of installation may be disabled for any of several reasons. There are many potential reasons, especially during a disaster or emergency event, why built in systems may become dysfunctional. In this embodiment, to overcome a malfunction, a portable amplifier kit  804  is connected to a portable outdoor antenna  805  via an outdoor antenna cable  805 A connected to the outdoor antenna amplifier port  805 B of the amplifier. The indoor antenna port cable  816  connects the amplifier kit to the standard building interface indoor antenna front port  816 A to utilize the built in indoor antenna array which is found to be functioning without problem at the moment. 
         [0312]    The standard building interface outdoor antenna front port  817 A provides a connection to the outdoor antenna conveniently outside the building. The built in indoor antenna  819  is connected to the interface box as well. In the event, the built in outdoor antenna was disabled or not functioning, a portable outdoor antenna could be connected directly to the amplifier kit. In this way, interface box&#39;s connections to the indoor antenna could still be utilized, while problems associated with the built in outdoor antenna could be avoided. 
         [0313]    In this embodiment, the interface box mechanism provides a valuable timesaving and safety enhancement as there is no need for an operator to enter the building, instead using an hybrid configuration both the outdoor antenna and the amplifier are able to be connected quickly and remain outside with the operator. 
         [0314]      FIG. 8G  is a schematic  800 B of the full built-in system utilizing a standard interface box. In this embodiment, a full built-in system utilizing a standard interface box provides a fixed In-Building Communication enhancement treatment. A four-port standard building interface box  820  may be secured directly to the building. The interface box may include: a standard building interface indoor antenna front port  816 A, a standard building interface outdoor antenna front port  817 A, a built in booster outdoor antenna front port  821 A, and a built in booster indoor antenna front port  822 A. A built in outdoor antenna  818  and a built in indoor antenna  819  are fixed to the building and are connected to the interface box. 
         [0315]    A BDA or other booster may be attached to the building and connected to the interface box as a built in booster. A jumper, a short segment of cable, or other connector  821  may be used to connect the built in outdoor antenna front port to the built in booster outdoor antenna front port. Another jumper, a short segment of cable, or other connector  822 , may be used to connect the built in indoor antenna front port to the built in booster indoor antenna front port. In both cases, the ports are polarized so that the proper connectors or fitting with the appropriate polarity must be used to make the proper connection corresponding to the cable leading to the proper antenna system. 
         [0316]    In this embodiment, the building has a fixed In-Building Communication enhancement treatment and, if all of these fixed systems are functioning without problem, no portable components are required for coverage enhancement. 
         [0317]    However, if any built in components become damaged or malfunction, portable replacements may be easily substituted to restore coverage enhancement.  FIG. 8H  is a schematic  800 H of the built-in system using portable systems bypassing a failed built in antenna and failed built in amplifier. In this embodiment, a portable amplifier kit  804  and a portable outdoor antenna  805  are connected to an interface box attached to a building which has been previously treated with a fixed In-Building Communication system. In the schematic, both the outdoor antenna and the booster which were part of the fixed In-Building Communication enhancement treatment are broken and not functioning. 
         [0318]    However, the interface box provides the necessary connecting ports for a portable amplifier kit  804  to connect to the remaining operational components of the fixed In-Building Communication enhancement treatment easily. In this embodiment, the portable outdoor antenna  805  is connected to the outdoor antenna portable amplifier port  805 B with an outdoor antenna cable  805 A. An indoor antenna port cable  816  connects to the standard building interface indoor antenna front port  816 A to the portable amplifier kit indoor antenna port thus connecting and utilizing built in indoor antennas which are part of the fixed in-building communication systems still functioning properly. This flexible configurability is enabled via the building standard IBC Interface Box, a key element of the present invention. 
         [0319]    Overall, the IBC Interface Box enables a portable solution to be used in the event any components of the fixed in-building communication enhancement are disabled. This allows a booster such as a BDA to be stored safely off-site and applied quickly as an emergency backup. This embodiment also demonstrates important set up time and cost reduction advantages. A BDA stored off site provides important back up for a number of buildings in the event an emergency damages a fixed system at any of them. The interface box makes the functioning components of the fixed in-building communication enhancement system in a given building easily accessible in the relative safety of the building&#39;s exterior to the first responders during an emergency or non-emergency event. 
         [0320]      FIG. 8I  is a schematic  800 I of portable deployment showing a portable amplifier kit located midway between portable outdoor and indoor antennas and including an extension antenna kit. A portable amplifier kit  804  is connected to a portable outdoor antenna  805  via an indoor antenna cable, long segment  807 , a cable coupler  813 , and an outdoor antenna cable  805 A. The extended cable length may be used to provide the optimal positioning of the outdoor components (amplifier kit and outdoor antenna), indoor components (indoor antenna and cable), sufficient length to cable around a radio barrier, necessary isolation between the indoor antenna and outdoor antenna, sufficient slack to enter the building entranceway quickly, or other safety or operational consideration. 
         [0321]    The amplifier kit  804  is connected to the indoor antenna via an extension cable  812  which is connected to a portable extension antenna stand  809 . The portable extension antenna stand  809  provides connection to a portable indoor antenna  806  and an extension indoor antenna  811 . An extension antenna selection switch  810  is located between the extension indoor antenna  811  and the portable extension antenna stand  809 . In this embodiment, extensions are demonstrated between the amplifier kit and the outdoor antenna and between the amplifier kit and the indoor antenna. The portable antenna stand may provide extension cable for connecting the amplifier kit to an indoor antenna. In addition, the portable antenna stand may have an alternate connection to an alternate antenna stand. 
         [0322]      FIG. 9A  is a gain map  900 A depicting a building with no treatment receiving a downlink transmission. A portable radio receiver  950  in a building  906  receives a downlink transmission from a radio site transmitter  901 . The radio site transmitter has an output power or Effective Radiated Power (ERP) of about 40 dBm  901 A. Assuming a frequency of about 860 MHz, for example, the transmitted signal would then have a loss of approximately −105.0 dB after traveling 5 km  905 AA through free space. (Other conditions may affect the transmission during its transmission such as humidity, weather, and other atmospheric conditions. Testing should take place at a given site to determine suitability for each particular location.) As a result, the signal at this point arriving at the building has an estimated power level of −65.0 dBm  905 A. Upon reaching the building, the signal experiences an additional loss of 40 dB  906 AA as it travels through Fire Type 1 building material (heavy concrete or masonry construction) providing a power level of −105.0 dBm  906 A to the portable radio receiver inside the building. This signal level is below acceptable levels generally required for error free reception of transmitted information. This is one indication of the need for radio coverage enhancement. 
         [0323]      FIG. 9B  is a gain map  900 B depicting a building with portable coverage enhancement treatment receiving a downlink transmission. A portable radio receiver  950  receives a downlink transmission from a radio site transmitter  901 . A dotted line forms a box around the donor antenna, cable, amplifier, cable, and indoor antenna components representing the portable coverage enhancement system that is applied to the building. Once again, the radio site transmitter  901  has an ERP  901 B of about 40 dBm. The transmitted signal is attenuated approximately 105 dB after traveling 5 km  905 BB through free space. The signal at this point has a power level of −65.0 dBm  905 B. Upon reaching a directional donor antenna  910 , the signal experiences a gain of 10 dB  910 BB providing a signal power level of −55.0 dBm  910 B to the coaxial connecting cable  915 . 
         [0324]    Assuming the use of typical low loss coaxial cable, the signal next experiences a loss of about (1.5 dB  915 BB traversing the cable  915  for approximately 3 m  915 BB. The signal power level reaching the amplifier  920  is therefore about −55.5 dBm  915 B. The amplifier  920  provides a gain of 75 dB  920 BB boosting the signal power level to 19.5 dBm  920 B. Cable  925  leads from the amplifier to an indoor antenna approximately and is 30 m in length imparting an expected loss of 5 dB  925 BB which further reduces the signal power to 14.5 dBm  925 B. The cable may lead from outside of the building where the amplifier kit and donor antenna are typically located in this embodiment to the indoor antenna which is typically located inside of the building in this embodiment. The cable may cross the exterior wall of the building or other barrier. Using an amplifier to boost the received signal and a low loss cable to deliver the boosted signal to an indoor antenna across all building wall or other material attenuators is advantageous. It provides a by-pass of the building wall and other attenuators that weaken an already low signal level below levels acceptable for reliable communications within. 
         [0325]    An omni directional antenna may be used as an indoor antenna  940  with no appreciable gain or loss. In the scenario of  FIG. 9B , the signal radiates from the indoor antenna 30 m from the indoor antenna through free space  945  before finally reaching the portable radio receiver  950  experiencing a loss of about 60 dB  945 BB reaching the portable radio at a power level of about −45.5 dBm  945 B. The signal level available to the portable receiver in the coverage enhanced scenario of  FIG. 9B  is therefore 60 dB higher than the untreated scenario depicted in  FIG. 9A  and is well above acceptable levels for error free reception of transmitted information. 
         [0326]    The gain map show in  FIG. 9B  shows the benefit to signal power level of the treated (−45 dBm versus the untreated gain map shown in  FIG. 9A  where the received signal strength was −105.0 dBm  905 A. As stated, the gain in signal strength provided by the portable coverage enhancement system is significant as it may enable an emergency responder to receive a life saving communications over the portable radio while inside the building. 
         [0327]      FIG. 9C  is a gain map  900 C complementary to the scenario of  FIG. 9B  depicting a portable radio  950  sending an uplink signal from inside a building with portable treatment. The portable radio  950  has an ERP  950 C of about 30 dBm. A dotted line again delineates the portable coverage enhancement system being applied to the building. The transmitted signal is attenuated approximately 60 dB after traveling 30 m  945 CC through free space. The signal at this point has a power level of −30.0 dBm  945 C. Upon reaching an indoor antenna, no appreciable gain or loss  940 CC is experienced by the signal and the signal has a power level of −30.0 dBm  940 C. The signal next experiences a loss of 5.0 dB  925 CC as the signal travels through a typical low loss coaxial cable approximately 30 m in length. At this point, the signal power is −35.0 dBm  925 C. The loss experienced by the radio signal traveling through cable as the cable exits the building is preferable to the loss experienced by a signal exiting the building which must travel directly through the building exterior wall and other physical structures. The amplifier  920  is configured to provide a gain of 60 dB  920 CC boosting the signal power level to 25 dBm  920 C. Cable  915  from the amplifier leads to the portable donor antenna approximately 3 m further imparting a loss of about −0.5 dB  915 CC reducing signal power to 24.5 dBm  915 C. A Yagi directional antenna may be used as the donor antenna  910 CC to provide an important directional gain and reduce potential interference. In the scenario of  FIG. 9C , the signal radiates from the donor antenna about 5 km through free space  905 CC before finally reaching the radio site  901  experiencing a loss of about −105 dB  905 CC where the signal reaches the portable radio at a level expected to be −70.5 dBm  905 C. The signal level available to the receiver in the coverage enhanced scenario of  FIG. 9C  is well above acceptable levels for error fret reception of transmitted information. 
         [0328]    The gain map in  FIG. 9C  illustrates the benefit to signal power level of the treated system (−70.5 dBm) for sending a radio transmission from inside a building. As stated previously, the gain in signal strength provided by the portable coverage enhancement system is significant because it may enable an emergency responder to send a life saving communications over the portable radio inside the building. 
         [0329]      FIG. 9D  is a gain map  900 D depicting a building with no treatment receiving a downlink transmission from an alternate source  901 . A portable radio receiver  950  in a building  906  receives a downlink transmission from a radio site transmitter  901 . The radio site transmitter has an output power or Effective Radiated Power (ERP) of 40 dBm  901 D. Assuming a frequency of about 860 MHz for example, for the transmitted signal would experience a loss of approximately −90.0 dB after traveling 1 km  905 DD through free space. As a result, the signal at this point has a power level of about −50.0 dBm  905 D. Upon reaching the building, the signal experiences an additional loss of about 50 dB  906 DD as the radio signal travels through Fire Type 1 building material (heavy concrete or masonry construction) providing a power level of −100.0 dBm  906 D to the portable radio receiver inside the building. This signal level is below acceptable levels generally required for error free reception. 
         [0330]      FIG. 9E  is a gain map  900 E depicting a building with hybrid treatment receiving a downlink transmission while in passive configuration. A portable radio receiver  950  receives a downlink transmission from a radio site transmitter  901 . A dotted line is illustrated forming a box around the jumper cable which connects the passive components applied to the building through the standard interface box  601 . The radio site transmitter  901  has an ERP  901 E of about 40 dBm. The transmitted signal is attenuated approximately 90 dB after traveling 1 km  905 EE through free space. The signal at this point has a power level of −50.0 dBm  905 E. Upon reaching a donor antenna  910 , the signal experiences a gain of 10 dB  910 EE providing a signal power level of about −40.0 dBm  910 E to coaxial connecting cable  915 . The donor antenna in this embodiment may also be a directional antenna, such as a Yagi antenna. In this embodiment, the antenna may be in an outdoor location fixed to the building. Assuming the use of typical low loss coaxial cable, the signal next experiences a loss of about 2.5 dB  915 EE traveling through the cable  915  for approximately 15 m  915 EE. The signal power level reaching the jumper  921  is −42.5 dBm  915 E. The jumper  921  is part of the interface box  601  and being very short provides no appreciable gain or loss  921 EE leaving the signal power level largely unchanged at −42.5 dBm  921 E. Cable  925  leads from the jumper in the interface box to a cable about 15 m in length imparting a loss of −2.5 dB  925 BB further reducing the signal power to −45.0 dBm  925 E. The cable may lead from the interface box which is mounted on an exterior wall of the building to the indoor door antenna which may be located on the inside of the building in this embodiment. The cable may cross the exterior wall of the building or other barrier. Enabling the signal to cross the barrier inside of a cable is preferable to attempting to penetrate the exterior wall or other additional barriers directly. As a result, transmission of the radio signal in the cable provides a by-pass of the radio signal around the building wall and prevents the building wall from weakening the radio signal significantly. 
         [0331]    An omni directional antenna may be used as an indoor antenna  940  with no appreciable gain or loss  940 EE. In the scenario of  FIG. 9E , the signal radiates from the indoor antenna about 10 m through free space  945 EE before finally reaching the portable radio receiver  950  experiencing a loss of about 50 dB  945 EE. The signal reaches the portable radio at a power level of about −95.0 dBm  945 E. The signal level available to the portable receiver in the coverage enhanced scenario of  FIG. 9E  is 5 dB higher than the untreated scenario depicted in  FIG. 9D . The gain map in  FIG. 9E  illustrates a small gain to signal power level of the passively treated versus untreated scenario (−95 dBm versus the untreated gain map shown in  FIG. 9D  where the received signal strength was −100.0 dBm  906 D). The passive enhancement is generally of limited application being useful in a small number of special circumstances where tower signal strength is very high, building attenuation is very high, cable runs for the installation are relatively short, and indoor communications is needed only in a relatively concise area of the building interior in close proximity to the indoor antenna. 
         [0332]      FIG. 9F  is a gain map  900 F depicting a building with a hybrid treatment receiving a downlink transmission using a portable amplifier configuration. A portable radio receiver  950  receives a downlink transmission from a radio site transmitter  901 . A dotted line forms a box around the amplifier. The box includes the components portable coverage enhancement applied to the building through the standard interface box  601 . The radio site transmitter  901  has an ERP  901 E of 40 dBm. The transmitted signal is attenuated approximately 90 dB after traveling 1 km  905 FF through free space. The signal at this point has a power level of −50.0 dBm  905 F. Upon reaching a donor antenna  910 , the signal experiences a gain of 10 dB  910 FF providing a signal power level of −40.0 dBm  910 F to the coaxial connecting cable  915 . The donor antenna in this embodiment may also be a directional antenna, such as a Yagi antenna. In this embodiment, the outdoor antenna may be fixed to the building. 
         [0333]    Assuming the use of typical low loss coaxial cable, the signal next experiences a loss of about 2.5 dB  915 FF from traveling through the cable  915  for approximately 15 m. The cable may connect the directional antenna on the outside of the building to a standard interface box also mounted on the exterior of the building. The signal power level reaching the amplifier  920  is −42.5 dBm  915 F. The amplifier  920  is connected to the interface box  601  and provides again of about 70 dB  920 FF providing an improved signal power level of about 27.5 dBm  920 F. The amplifier may also be located outside the building. Cable  925  leads from the amplifier back to the interface box and connects with a cable about 15 m in length to an indoor antenna imparting a loss of about −2.5 dB  925 FF which further reduces the signal power at this point to 25.0 dBm  925 F. The cable may lead from the interface box which is mounted on an exterior wall of the building to the indoor door antenna which may be located on the inside of the building in this embodiment. The cable may cross the exterior wall of the building or other barrier. The signal crosses the exterior wall of the building (and other physical structures or barriers) inside of the cable. This cable by-pass of the exterior wall is preferable to attempting to penetrate the exterior wall or other additional barriers directly with a radio signal. As a result, transmission of the radio signal in the cable provides a by-pass of the radio signal from direct interference or attention from the building wall. 
         [0334]    An omni directional antenna may be used as an indoor antenna  940  with no appreciable gain or loss  940 FF. In the scenario of  FIG. 9F , the signal radiates from the indoor antenna about 10 m through free space  945 FF before finally reaching the portable radio receiver  950  experiencing a loss of 50 dB  945 F where the signal reaches the portable radio at a power level of −25.0 dBm  945 F. The signal level available to the portable receiver in the coverage enhanced scenario of  FIG. 9F  is about 70 dB more powerful than the passive scenario depicted in  FIG. 9E  and is 75 dB more powerful than the passive scenario depicted in  FIG. 9D   
         [0335]    The gain map in  FIG. 9F  illustrates the benefit to signal power level from the portable treatment (−25 dBm versus the untreated gain map shown in  FIG. 9D  and the passive system as shown in  FIG. 9E . The gain map shows in  FIG. 9F  shows the benefit to signal power level for sending a radio transmission in a building. As stated previously, the gain in signal strength provided by the hybrid enhancement system is significant. 
         [0336]      FIG. 9G  is a gain map depicting a building with portable treatment sending an uplink transmission while in passive configuration. A portable radio receiver  950  sends an uplink transmission to a radio site transmitter  901 . A dotted line forms a box around the jumper cable which connects the passive components applied to the building representing the standard interface box  601 . The portable radio  950  has an ERP of about 30 dBm  950 G. The transmitted signal is attenuated approximately 50 dB after traveling 10 m  945 GG through free space. The signal at this point has a power level of −20.0 dBm  945 G. Upon reaching an indoor antenna  940 , the signal experiences no appreciable gain or loss  940 GG providing a signal power level of −20.0 dBm  940 G to coaxial connecting cable  925 . 
         [0337]    Assuming the use of typical low loss coaxial cable, the signal next experiences a loss of 2.5 dB  925 GG traveling through the cable  925  for approximately 15 m  92500 . The signal power level reaching the jumper  921  is −22.5 dBm  925 G. The jumper  921  connects parts of the interface box  601  and provides no appreciable gain or loss  921 GG leaving the signal power level large unchanged at −22.5 dBm  921 G. The signal then travels from the jumper  921 GG in the interface box to a cable 15 m in length imparting a loss of −2.5 dB  925 BB which further reduces the signal power to −25.0 dBm  915 G. The cable may lead from the interface box which is mounted on an exterior wall of the building to an outdoor antenna which may be located on the outside of the building and be fixed to the building in this embodiment. The cable may cross the exterior wall of the building or other barrier or proceed up to the building in a conduit alongside an exterior wall. Enabling the signal to cross the barrier inside of a cable is preferable to attempting to penetrate the exterior wall or other additional barriers directly. As a result, transmission of the radio signal in the cable provides a by-pass of the radio signal directly interfacing with the building wall and being weakened significantly. 
         [0338]    A directional antenna may be used as a donor antenna  910 GG providing an appreciable gain of 10.0 dB  910 GG. In the scenario of  FIG. 9G , the signal radiates from the outdoor antenna 1 km through free space  90500  before finally reaching the radio site  901  experiencing a loss of 90 dB  905 GG where the signal reaches the radio site with power level −105.0 dBm  905 G. This may or may not be adequate level for assured communications depending upon site receiver sensitivity and attendant RF noise conditions. 
         [0339]      FIG. 9H  is a gain map  900 H depicting a building with hybrid system utilizing portable amplifier treatment sending an uplink transmission. A portable radio receiver  950  sends an uplink transmission to a radio site transmitter  901 . A box formed of dotted lines is illustrated around the amplifier. The box includes the components of the portable coverage enhancement being applied to the building through the standard interface box  601 . The portable radio  950  has an ERP of 30 dBm  950 H. The transmitted signal is attenuated approximately 50 dB  945 HH after traveling 10 m through free space. The signal at this point has a power level of −20.0 dBm  945 H. Upon reaching an indoor antenna  940 , the signal experiences no appreciable gain or loss  940 HH providing a signal power level of −20.0 dBm  940 F to the coaxial connecting cable  925 . The indoor antenna in this embodiment may also be an omni directional antenna. 
         [0340]    Assuming the use of typical low loss coaxial cable, the signal next experiences a loss of 2.5 dB  925 HH traveling through the cable  925  for approximately 15 m. The cable may connect the indoor antenna on the inside of the building to a standard interface box mounted on the exterior wall of the building. The signal power level reaching the amplifier  920  is −22.5 dBm  925 H. The amplifier  920  is connected to the interface box  601  and provides a gain of about 50 dB  920 HH providing an improved signal power level of about 27.5 dBm  920 H. The amplifier may also be located outside the building and applied as part of a portable system. Cable  915  leads from the interface box to an outdoor antenna imparting a loss of 2.5 dB  915 HH which reduces the signal power to about 25 dBm  915 H. The cable may lead from the interface box which is mounted on an exterior wall of the building to a directional antenna which may be located on the outside of the building in this embodiment. 
         [0341]    A directional antenna may be used as the donor antenna  910 HH and provides a gain of about 10 dB  910 HH. In the scenario of  FIG. 9H , the signal radiates from the outdoor antenna through about 1 km of free space  905 HH before finally reaching the radio site  901  experiencing a loss of about −90 dB  905 HH where the signal reaches the radio site at a power level of −55.0 dBm  905 H. The signal level available to the tower site is clearly adequate to support error free communications. 
         [0342]    The gain map in  FIG. 9H  illustrates the benefit to signal power level from the portable treatment (−55 dBm) versus the passive gain map in  FIG. 9G  (−105 dBm). The gain map in  FIG. 9H  shows a clear benefit to signal strength for sending a radio transmission in a building with the portable treatment. In this embodiment, the gain in signal strength provided by the hybrid enhancement system is significant. 
         [0343]      FIG. 9I  is a gain map  900 I depicting a building with portable system treatment including an extended antenna forming a distributed antenna system which receives a downlink transmission. A portable radio receiver  950  receives a downlink transmission from a radio site transmitter  901 . A dotted line forms a box representing the portable communication enhancement. The box  960  includes: a donor antenna  910 , a cable  915 , an amplifier  920 , cable  925 , a first coupler port  930 , cable  935 , a first indoor antenna  940 , a second coupler port  931 , cable  936 , and a second indoor antenna  941 . The radio site transmitter  901  transmits with ERP  901 I of 40 dBm. The transmitted signal is attenuated approximately 105.0 dB after traveling about 5 km  905 II through free space. The signal at this point has a power level of about −65.0 dBm  905 I. Upon reaching a donor antenna  910 , the signal experiences a gain of about 10 dB  910 II providing a signal power level of −55.0 dBm  910 I to the coaxial connecting cable  915 . The donor antenna in this embodiment may also be a directional antenna, such as a Yagi antenna. In this embodiment, the antenna may be in an outdoor location applied as part of a portable antenna kit. 
         [0344]    Assuming the use of typical low loss coaxial cable, the signal next experiences a loss of about −0.5 dB  915 II traveling through the cable  915  for approximately 3 m. The cable may connect the directional antenna on the outside of the building to an amplifier. The signal power level reaching the amplifier  920  is −55.5 dBm  915 I. The amplifier  920  provides a gain of 75 dB  920 II providing an improved signal power level of 19.5 dBm  920 I. The amplifier may also be located outside the building. Cable  925  from the amplifier has a length of about 30 m imparting a loss of about 5.0 dB  925 II which further reduces the signal power to 14.5 dBm  925 I. The cable may lead from the outside of the building to the inside of the building in this embodiment. The cable may cross the exterior wall of the building or other barrier. Enabling the signal to cross a physical barrier such as a wall while inside of a cable is preferable to attempting to penetrate the exterior wall or other additional physical barriers directly. As a result, transmission of the radio signal in the cable provides an effective by-pass of the radio signal past the building wall with a smaller loss than being transmitted directly through the wall. 
         [0345]    A directional coupler  1023  may be used to direct the radio signal in two paths. Following from cable  925 , the radio signal may be received through a first coupler port  930  imparting a loss of 1.3 dB by a cable which has a length of about 30 m imparting a further loss of 5.0 dB. The radio signal is routed to a second coupler port which imparts a loss of 6.0 dB to a second cable having a length of about 3 m and imparting a further loss of about 0.5 dB. The signal arriving ultimately at a first portable radio located 15 m distant from first indoor antenna  940  along first coupler port path  930  is estimated to be −46.8 dBm. The signal arriving at a second portable radio located 15 m distant from a second indoor antenna  941  along second coupler port path  931  is estimated to be −47.0 dBm. This illustrates the benefit from the portable invention to two portable radio users located as far apart as 60 m inside a building that would otherwise have unreliable or nonexistent communications. 
         [0346]    In  FIG. 9I , the directional coupler enables the benefit of this portable communication enhancement to reach more than one portable radio user. In addition, a wider coverage area can be obtained by using more than one indoor antenna without requiring the use of an additional amplifier. The benefits of this portable communication system are significant as it is simple to establish communication enhancement without significant changes to existing infrastructure and without incurring significant additional expense for more equipment. 
         [0347]      FIG. 10  is a view  1000  of a portable extended antenna kit once removed from the bag in which it is conveniently transported. The portable extended antenna kit when removed from the bag rests on extended tripod legs  1003 A. The tripod legs may have rubber feet  1012  which engage the ground or other resting surface. The portable extended antenna kit has a telescoping mast  1002  and a telescoping mast adjuster  1011  located near the top portion of the portable antenna kit. The telescoping mast  1002  may be elevated. An extension indoor antenna  1008  is located near a central portion of the portable extended antenna kit attached directly to the spine of the portable extended antenna kit cable organizer. The extension indoor antenna  1008  is surrounded by a coil of wound cable when the cable is in its stored location. An extension antenna selection switch  1005  and an extension antenna selection switch actuator  1006  are located beneath the indoor antenna in an interior position of the coil secured around the periphery of the cable organizer. 
         [0348]      FIG. 10A  is a close-up view  1000 A of the portable extended antenna kit once removed from the bag. A central portion of the portable extended antenna kit is shown including: the extension indoor antenna  1008 , extension indoor antenna cable  1013 , and the extension antenna selection switch actuator  1006 . Tripod legs  1003 A,  1003 B are seen extending in a downward direction behind the central portion of the portable extended antenna kit. Leg braces  1004  are shown extending in an upward direction behind a lower end of the central portion of the portable extended antenna kit. The extension antenna selection switch actuator  1006  is connected to an extension antenna selection switch  1005  and a terminator  1007 . One end of the indoor antenna is connected to a pigtail cable. This pigtail cable is connected to an indoor antenna cable which is stored in a coil in a lower portion of the portable extended antenna kit. This indoor antenna cable  1013  leads to the extension antenna selection switch  1005 . The extension antenna selection switch  1005  has three ports including one used for terminator  1007 , one port coupling to a cable  1014  leading to directional coupler  1023 , and one terminating the aforementioned indoor antenna cable  1013 . 
         [0349]      FIG. 10B  is a rear perspective view  1000 B of the portable extended antenna kit. A long segment of extension cable is coiled around the cable organizer and held in place with a cable retention strap  1022 . The cable mention strap  1022  is fastened to a cable retention strap pin  1021  on a top portion of the cable organizer. A short segment of the long extension cable  1010  is connected to a directional coupler  1023 . The directional coupler  1023  rests on a directional coupler mounting shelf  1024  in the rear of the portable extended antenna kit. An extension indoor antenna switch cable connection  1015  is directly connected to the directional coupler  1023  in the rear of the portable extended antenna kit. 
         [0350]      FIG. 10C  is a close-up rear perspective view  1000 C of the portable extended antenna kit. The cable retention strap pin  1021  is shown on the top rear of the portable extended antenna kit. The long segment of long extension cable  1025  is coiled around the cable organizer in deploy position as the cable retention strap  1022  is no longer secured to the cable retention strap pin  1021  and holding the long segment of long extension cable  1025  in place. The directional coupler  1023  is seated on the directional coupler mounting shelf  1024  and is connected to a cable input to the extension antenna kit  1009  on the left end of the directional coupler. A short segment of cable  1013  connects to the extension indoor antenna pigtail  1020  and to the extension antenna selection switch  1005 . 
         [0351]    The directional coupler  1023  is used to unevenly split and/or combine signals. The directional coupler may include three ports: including an input port, an output port, and a coupled port. The coupled port is DC isolated (open circuit) from the input or output ports. The directional, input, and output ports must be connected properly. The directional coupler may have less loss than a splitter at one port at the expense of a greater loss at the other port. A directional coupler may be to provide a long segment of cable with several antenna points. Additionally, in a vertical configuration a directional coupler may be used to provide antenna feed(s) on each floor in a multi-floor building. The directional coupler provides low loss on the thru port and versatile selection of coupled ports. As a result, the directional coupler can be an important component in a distributed antenna system. 
         [0352]      FIG. 10D  is a view  1000 D of the portable extended antenna kit in deployed configuration. The extension indoor antenna  1008  is mounted on top of the telescoping mast of the portable extended antenna kit. All three tripod legs  1003 A,  1003 B, and  1003 C are extended and engaging directly the ground or other resting surface. Leg braces  1004  connect each of the tripod legs by connecting to the portable extended antenna kit. Both cable retention straps  1022  are disengaged enabling the long segment of long extension cable  1025  to deploy from the portable extended antenna kit. The extension indoor antenna  1008  is connected to an extension indoor antenna cable  1013  which connects to the extension antenna selection switch  1005  in a central portion of the portable extended antenna kit. Cable input to extension antenna kit  1009  leads to a directional coupler port at a top rear portion of the portable extended antenna kit. An indoor antenna  133  connects to a long segment of long extension cable  1025  leading from another directional coupler port at the top rear portion of the portable extended antenna kit. The portable extended antenna kit in deployed configuration provides cable extension to enable the indoor antenna  133  to have an increased portable range, while an extension indoor antenna  1008  mounted directly to the portable extended antenna kit provides increased communication coverage in the direct vicinity surrounding the portable extended antenna kit if optionally enabled by selector switch  1005 . In this way, a distributed antenna system can be applied and extended with modular additions quickly providing incremental extensions to the coverage area, so that communications can be maintained and increased without disconnecting communication previously established. 
         [0353]      FIG. 10E  is an alternate view  1000 E of the portable extended antenna kit in deployed configuration.

         [0355]      FIG. 11  is a view  1100  of the portable extension cable reel. Cable  1101  is wound around a central spool having a first end of cable  1104  on the left and a second end of cable on the right  1105 . The portable extension cable reel has wheels on one side  1103  engaging the ground and a frame  1106  engaging the ground on the other. The portable extension cable reel has a spool end  1107  which serves as a handle to turn the spool to deploy cable. The portable cable extension reel may be used to transport an extended amount of cable. Alternatively, the portable cable extension reel may be used in a stationary position to dispense cable from the central spool. 
         [0356]      FIG. 12  is a view of the portable indoor antenna mounting adapter  1200 .

         [0360]      FIG. 13  is a view  1300  of the optional outdoor antenna kit. The optional outdoor antenna kit  1300  includes a case  1301  which houses an outdoor antenna  1302 . The optional door antenna kit case  1301  includes a door and a bottom case portion. Both the inside of the bottom case portion has padding  1305  and the inside of the door has padding  1304 . The door and the bottom case portion of the optional antenna kit case  1301  are separated by a hinge  1308 . The door of the case includes a locking mechanism in the form of a latch  1306 . A handle  1307  is located in the central top edge of the door and in central portion of the case so that the when the door is closed the two handles are aligned. Cable  1303  is wound around the outer periphery of the bottom case portion. Four cable winding posts and feet  1309  are located at a bottom portion of the case to engage the ground or other resting surface and provide locations around which the cable can be wound (only two posts and feet  1309  are visible in this view). A cable retention strap  1310  is used to secure the cables together. 
         [0361]    The optional outdoor antenna kit  1300  provides a secure way to transport a directional outdoor antenna and cable in an orientation that can be easily stored and transported and quickly deployed. The directional antenna may be secured in an internal cavity surrounded by padding and the cable is secured around the case providing storage that is easy to access and carry. 
         [0362]      FIG. 13A  is a top view  1300 A of the optional outdoor antenna kit. A view of the case  1301  is illustrated from the top in closed position. The wound cable  1303  surrounds the periphery of the outdoor antenna kit and protrudes slightly on the short sides of the antenna kit. A latch  1306  is used to secure the door of the case in a closed position. A handle  1307  in a central position on one side can be engaged by hand to allow one person to carry the case. 
         [0363]      FIG. 13B  is a front view  1300 B of the optional outdoor antenna kit. The latches  1306  extend in a downward vertical position. The outdoor antenna kit rests on the antenna at the bottom of the antenna kit. The handle  1307  is attached to the antenna kit in two places in the front of the antenna kit case. 
         [0364]      FIG. 13C  is a bottom view  1300 C of the optional outdoor antenna kit. The case  1301  has a cable  1303  surrounding the perimeter of its bottom surface. The cable retention strap  1310  secures the cable in place against the optional outdoor antenna kit case  1301 . 
         [0365]    The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Certain adaptations and modifications of the invention will be obvious to those skilled in the art. Therefore, the above discussed embodiments are considered to be illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
