BACKGROUND OF THE INVENTION
The invention relates generally to wireless communication systems and, more particularly, to wireless communication system devices that use radio frequencies for transmitting and receiving voice and data signals within an internal communications network and to an external communication networks.
Wireless communication systems continue to grow, particularly in the areas of cellular and digital telephony and in paging systems. Wireless systems are especially popular in remote areas of the world that have limited wired service because of the cost and difficulty of building a wired infrastructure.
Traditional wireless communication systems such as cellular telephones use radio communication between a plurality of subscriber units within the synchronous wireless system and between subscriber units and the Public Switched Telephone Network (PSTN) for calls that are outside of the wireless system. Most of these systems are characterized by wireless mobile telephone units communicating synchronously with base stations that are connected to centralized mobile switching centers (MSC), which are in turn connected to the PSTN. The centralized MSC performs a number of functions, including routing wireless mobile units calls to other mobile units and wired (land-line) users and routing land-line calls to mobile units. At no time do these traditional wireless communications systems allow the handset to interface with the PSTN directly. The very core of the centralized wireless communications theory requires every PSTN interface to be made through an MSC. This is the only interface allowed.
Others' systems use point-to-point radio communication where mobile units may communicate with other mobile units in the local area. They send origin and destination address formation and make use of squelching circuits to direct the wireless transmission to the correct destination address. Most of these systems do not appear to provide a connection to a PSTN to send and receive calls outside the wireless network. This type of system is decentralized, but because of the decentralization, collecting accurate billing information may be a problem.
Another form of wireless system is called a local multipoint distribution service (LDMS). In an LMDS system, a local area or cell that is approximately 4 km in diameter contains fixed base stations, geographically distributed throughout the local area. One or more antennas within the local area receive calls from the fixed base stations and relay the calls to other fixed base stations. In order for the system to work, the fixed base stations must be within the line-of-sight path of at least one of the antenna units. The LDMS does not provide for mobile stations. Calls can only be routed within the local area and not to an external network. The system is essentially a centralized system within a local area. If one station is not within the line of sight of the antenna, it is effectively cut off from communication.
There is a need for decentralized wireless communication system that is capable of handling voice and data communication that allows for a multiplicity of communication paths. It is desirable to have an ability to call on bandwidths as needed, to provide local communication links, and to access links to external networks. Such networks may include public switch telephone networks, high speed-broadband cable, Internet, satellites and radio emergency networks. It is desirable to have a system that does not require a centralized switching center, provides for secure operation, allows for control of the operational state of the internal network, provides for emergency notification and provides a way to collect revenue from the system. It is desirable to have elements within the system that allow for the remote controlled gathering of data, the preprogrammed remote gathering of data, the remote controlling of systems external to the internal network, the remote controlling of the change of state of systems external to the network, alternative paths for the relaying of signal extender signals, alternative paths for the relaying of handset, ComDoc or X-DatCom signals. It is also desirable to provide alternate direct-path communication between wireless handsets and the PSTN, without centralized switching or to provide alternate direct-path communication between remotely placed wireless data collection, reporting and remote control instruments and the PSTN, also without centralized switching. Such interfaces augment the conventional path routing and reduce call loads on any central communications interface. It is also prudent to oversee the entire operational state of the network, its various components and signal routing devices with an Artificial Intelligence-based Distributive Routing System; an artificial learning software based logic manager prepared to assist and/or provide guidance during any unfortunate catastrophic failure of major wireless infrastructure elements or during inevitable wireless set call connection failures due to peak hours call overloading experienced in a mature wireless system.

DETAILED DESCRIPTION OF THE INVENTION
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.
The present invention is directed to devices and methods that provide a user of a decentralized asynchronous wireless communication system for voice and data communication with the ability to select various communication paths and calling bandwidths as needed. It provides local communication as well as optional links to external networks, and does not require a synchronous centralized switching center. It further provides secure operation, emergency notification and a way to collect revenue from the system, and allows for control of the operational state of the internal network and optional remote control of the operational state of systems external to the network.
The present invention provides for a wireless remote external data communications module (X-DatCom) device that uses radio frequencies for asynchronously and remote transmitting and receiving voice and data signals within an internal network with multiple internal communication paths. It also provides for external communication paths for linking the internal network to external communication networks, including a direct connection to a Public Switched Telephone Network (PSTN) for uploading or downloading digital data and device programming and is capable of operating in isolated remote locations. Additional communications paths defined as ultra short range are also encompassed in the scope of the device to facilitate a communication between the device and other external network devices equipped for ultra short range communication. These include ultra-wide-band, Bluetooth, or infrared spectrum protocols.
The present communication system comprises five primary elements: handsets carried by mobile users, communications docking bays (ComDocs) for providing alternative connections, external data communications modules (X-DatComs) for remotely gathering data or remotely controlling systems external to the device or to the network, signal extenders for relaying handset, ComDoc or X-DatCom signals, and network extenders for interconnecting signals from signal extenders. The signal extenders and network extenders comprise the infrastructure equipment that is located at antenna tower sites while the ComDoc sets are located in a subscriber's home or business and X-DatComs comprise a varied array of remotely placed data gathering or remote control devices. Handsets, ComDocs and X-DatComs are assigned standard telephone numbers and are capable of placing and accepting calls with telephones in the Public Switched Telephone Network (PSTN) through the network extenders. Calls that are placed between handsets, ComDocs or X-DatComs contained within the asynchronous internal network do not require routing through a PSTN. The ComDoc interface device is designed to allow restricted and private access to a wireless handset owner's home or office telephone landline, thus creating a private link to the PSTN without necessity of routing the wireless call through the network extender for an interface to the PSTN. X-DatComs are varied in design to meet application needs but all have the capabilities of being placed in remote locations to gather data or control processes or devices external to their own circuitry or to the network. X-DatComs may facilitate a communication between other external network devices equipped for ultra short range communication. These include ultra-wide-band, Bluetooth, or infrared spectrum protocols. Besides handling regular voice and data, the overall system also supports a wide variety of telephone features such as Internet access, cable modem access, bi-directional data transfer and variable bandwidth wireless calling channels. Direct connection to other external networks include: the PSTN, cable and other wireless protocols via the multi-mode module in the RF section of handsets, ComDocs or X-DatComs. Ultimate control of the X-DatCom will be reserved for signals from within this decentralized asynchronous wireless communication network. The handsets, ComDocs and X-DatComs may have Wireless Fidelity (Wi-Fi) options to establish wireless connectivities to other devices. The communication between the elements can be monitored by a system-resident and decentralized Artificial Intelligence-based Distributive Routing System.
The Artificial Intelligence-based Distributive Routing System may comprise a resident and decentralized network of computers having a computer residing in each signal extender and each computer having an Artificial Intelligence software program to gather information regarding timely calling data, routing and wireless device use histories and to analyze the information for recommending or executing alternative communication paths within the entire system of the signal extenders and the network extender during excessive peak hours loading of the network extender or during a catastrophic failure of any signal extender or the network extender. The Artificial Intelligence System may further report the day's gathered information to each of the other signal extenders for comparative analysis and making logical suggestions to the handsets, communications docking bays and External Data Communications Modules operating within the system. The Artificial Intelligence System may further be programmed to gather relevant data from remotely placed external data communications modules by means of a wireless protocol established for operations of the system. The wireless protocol is established for operations of the system interfaced with a network including but not limited to Public Switch Telephone Network lines, a fiber optic communication link, a coaxial cable, a public TCP/IP network, a directional emergency tower to tower microwave link, a satellite communication link, a communication docking bay routed to other destinations and data collection devices selected by the Artificial Intelligence System.
The external data communications modules (X-DatComs) provide for remote gathering of data or control of systems external to the internal circuitry of the device or external to the network, with additional or alternative connectivity to the PSTN, if required. The X-DatCom is a fixed-base wireless set capable of asynchronously sending and receiving system calls and/or data and providing connection with a PSTN or other such external devices or networks as selected by the user. This device may also provide a redundant path to a PSTN for the uploading or downloading of data collected remotely or for the remote control of external devices within or external to the network or for the remote control of the operational state of devices internal or external to the network. The device is capable of serving as a wireless data interface for personal computers with data rates either flexible or fixed through the use of DWC Contiguous Channel Acquisition Protocols (CCAP)/(CCAP+) or preset wireless channel allocations.
The system is particularly suitable for operation in rural areas where population density is low and wireless coverage is either not currently available or not adequately serviced and where limited remote data gathering or remote control of systems or devices via wireless means is in operation. The system is suitable for operation in the United States using the PCS spectrum (1850 or the Wireless Communications Service (WCS) spectrum at 2320 2360 MHz that are licensed by the Federal Communications Commission (FCC) or any other such frequency as may be determined suitable above 50 megahertz and less than 5 gigahertz. The handset, the ComDoc and the X-DatCom incorporate a modular multi-mode capability to extend the wireless service area with a potential variety of standard wireless formats and bands, such as AMPS, D-AMPS, IS-95, IS-136, and GSM1900. This is an important feature because widespread deployment of a new wireless service takes appreciable time, and there are many other wireless standards from which to choose since these new customers may also venture into standard PCS or cellular markets. Besides the US rural market, other applications for present invention include emerging nations, especially those that presently have limited or no telephone service, and those communities or groups that require a stand alone wireless communication network that can be quickly and cost-effectively deployed. The low cost remote sensing and remote control of other devices and processing through such a versatile wireless device is critical to isolated rural economies and those of developing nations.
An embodiment of the present invention is a method of operating a wireless communication system for voice and data signals, the system comprising one or more macrocells and each macrocell having a plurality of microcells.

In yet another embodiment of the present invention is a method for operating a wireless communication system for voice and data signals, the system comprising one or more macrocells and each macrocell having a plurality of microcells. The method comprises establishing a local communication path for transmitting and receiving signals between a local communications docking bay (ComDoc) and a remotely placed local external data communications module (X-DatCom) within a same microcell via a signal extender, establishing an extended communication path for transmitting and receiving signals between an extended ComDoc and an extended external data communication module located within different microcells positioned within a same macrocell via signal extenders and a network extender, establishing a distant communication path for transmitting and receiving signals between a distant ComDoc and a distant external data communications module located within different microcells positioned within different macrocells via signal extenders and network extenders, and asynchronously transmitting and receiving half-duplex signals over the communication paths using pairs of assigned communication path frequencies stabilized by a GPS-based frequency reference source.

The wireless devices can be a handset, an external communications module, or a docking bay. The wireless devices can also have wireless fidelity (WiFi) options to provide connectivity to other devices within or outside the system.
Turning now to FIG. 1, FIG. 1 shows a deployment 10 of two embodiments 11, 12 of a wireless communication system connected to other communication networks 15, 16, 18, 19, and 1500 in accordance with the present inventive concepts. The wireless communication systems 11, 12 are composed of fundamental elements that include handsets 300, ComDocs 900, X-DatComs 400, signal extenders (SE) 600, and network extenders (NE) 800. The handsets 300 are similar in features and functions to cellular and PCS handsets. They support at least two mobile wireless protocols: a novel Direct Wireless protocol (DW mode) described in the present disclosure, and a secondary standard wireless protocol (roaming mode) selected from a multiple of protocols (AMPS, D-AMPS, IS-95, IS-136, and GSM1900). The present invention includes the DW protocol. The secondary protocol may be selected from several standard alternative protocols. The system infrastructure for the secondary protocol is not addressed in this disclosure. The wireless communication system infrastructure (SEs 600 and NEs 800) and the DW wireless protocol are completely independent of the secondary mode. In a preferred embodiment, there is no formal or actual connection between the signal extender (SE) 600 and the PSTN 19. The connection is accomplished by giving the SE its own ComDocs 900 waiting for the SE to utilize them wirelessly.
The X-DatCom 400 is a communications device utilizing two alternate wireless communications protocols, the DW Protocol for wireless communications over the frequencies also designated for DW wireless handsets, DW wireless ComDocs and an optional secondary wireless protocol (for each) selected from a multiple of protocols (AMPS, D-AMPS, IS-95, IS-136, and GSM1900), and a PSTN 19 landline communications protocol. The X-DatCom 400 is a remotely operated or preprogrammed wireless communications device designed to be remotely placed to gather data, send or receive data, transfer data, and control such other devices as may be attached to its circuitry externally. The device, in its simplest form, is a transmitter with related circuitry that gathers and wireless sends data on a predetermined schedule. In its most complicated form, the X-DatCom 400 is a remotely placed, remotely operated or preprogrammed autonomous ComDoc-like device without handset recharging capabilities; capable of remote control by wireless sets within the asynchronous wireless network or by the Artificial Intelligence-based Distributive Routing System 1300; a resident computer network within the asynchronous wireless network. The X-DatCom 400 may be operated as an alternative communications path for a DW wireless handset or ComDoc 400 to reach the PSTN 19 without accessing a signal path to the PSTN through the conventional signal extender 600 to network extender 800 frequency links, and network extender to PSTN interface. It may also serve as a communications path from available and attached landline telephone sets, through the X-DatCom 400 to a signal extender 600 to a DW wireless handset 300. The X-DatCom 400 can also serve as an alternative communications path for delivery of bi-directional wireless wide-band Internet services to a selected computer via a signal extender 600 to network extender 800 to PSTN 19 interface signal path. The signal extender (SE) 600 is a relay that amplifies and translates the frequency of wireless radio frequency (RF) signals between handsets 300 and a Network Extender (NE) 800, between two handsets 300, between a ComDoc 900 and signal extender 600, and between handset 300 to signal extender 600 to ComDoc 900 to PSTN 19, between an X-DatCom 400 and signal extender 600, and between handset 300 to signal extender 600 to X-DatCom 400 to PSTN 19. The X-DatCom 400 can also serve as an alternative communications path for delivering wireless signals to an external PCS network 1500 or for relaying signals from a computer through a ComDoc 900 to a signal extender 600 to the X-DatCom 400 to reach such an external network; PCS 1500.
The ComDoc 900 (Communications Docking Bay) is a communications device utilizing two alternate wireless communications protocols, the DW Protocol for wireless communications over the frequencies also designated for DW wireless handsets 300 and an optional secondary wireless protocol selected from a multiple of protocols (AMPS, D-AMPS, IS-95, IS-136, and GSM1900), and a PSTN 19 landline communications protocol. The ComDoc 900 is an alternative communications path for DW wireless handset 300 to reach the PSTN 19 without accessing a signal path to the PSTN 19 through the conventional signal extender 600 to network extender 800 frequency links, and network extender 800 to PSTN 19 interface. The ComDoc 900 is also an alternative communications path for the X-DatCom 400 to reach the PSTN 19 without accessing a signal path to the PSTN 19 through the conventional signal extender 600 to network extender 800 frequency links, and network extender 800 to PSTN 19 interface.
It also serves as a communications path from the home or office landline telephone sets, through the ComDoc 900 to a signal extender 600 to a DW wireless handset 300. The ComDoc 900 can also serve as an alternative communications path for delivery of bi-directional wireless wide-band Internet services to a home computer via a signal extender 600 to network extender 800 to PSTN interface signal path. The signal extender (SE) 600 is a relay that amplifies and translates the frequency of wireless radio frequency (RF) signals between handsets 300 and a Network Extender (NE) 800, between two handsets 300, between a ComDoc 900 and signal extender 600, and between handset 300 to signal extender 600 to ComDoc 900 to PSTN, between an X-DatCom 400 and signal extender 600, and between handset 300 to signal extender 600 to X-DatCom 400 to PSTN. The ComDoc 900 may be used to route a DW handset 300, via a Bluetooth interface to connect to the PCS network 1500 wirelessly. There are many permutations and combinations of signal paths that are possible in the present system. For example, handsets 300, ComDocs 900 or X-DatComs 400 in the same microcell may communicate with one another via a signal extender 600. Handsets 300, ComDocs 900 or X-DatComs 400 in different microcells but within the same macrocell may communicate with on another via signal extenders 600 and network extenders 800. Since computers and conventional telephones may be connected to a X-DatCom 400, these devices may also communicate with other devices connected to the wireless network 11, 14 or to 1500. Two or more computers may connect to one another via the wireless network, 11, 12 at a minimum data rate of 56 kbps using Contiguous Channel Acquisition Protocol, or up to a maximum data rate of 250 kbps using Contiguous Channel Acquisition Protocol Plus via a single signal extender 600. Similarly, since a laptop computer may be connected to a wireless handset 300, it may also communicate with other devices connected to the wireless network 11, 14 or 1500. Since a X-DatCom 400 may also be connected to a PSTN 19, cable or other communication network medium, a handset may communicate directly or indirectly via a signal extender 600 to a remotely placed X-DatCom 400 to a PSTN 19 network or cable network. An X-DatCom 400 may communicate via a signal extender 600 and a network extender 800 to a PSTN network 19 or may communicate via a signal extender 600 and a network extender 800 to a PSTN network 19 to an external device 1400 for remote data gathering or extended remote control or the external device 1400.
The antenna pattern between the SE 600 and handsets 300, DatCom 400 or ComDocs 900 is generally omni-directional, since the handsets 300 are typically mobile throughout the surrounding area of the SE 600 or the DatCom 400 or ComDocs 900 may be moved or placed in different locations at the discretion of the subscriber. The antenna pattern of a handset 300, a ComDoc 900 or an X-DatCom 400, operating in the in the secondary mode, are also omni-directional. In contrast, the antenna pattern between the SE 600 and NE 800 can be a narrow beam since the SE 600 and NE 800 sites are both at fixed locations. The SE 600 is analogous to a simplified “base transceiver station” or BTS in a cellular or PCS system. A key point to simplification is that the SE 600 does not switch, process, or demodulate individual channels or calls unless otherwise instructed by the Artificial Intelligence Computer Network 1300 to make such connections during a catastrophic failure of the NE 800. It is generally limited in function to relaying blocks of RF spectrum. The NE 800 is a central hub and primary switch for interconnecting calls both within the system and to external networks such as the PSTN 19. The NE 800 assists handsets 300 in establishing calls, assists in interconnecting ComDocs 900 and handsets 300, X-DatCom 400 and handsets 300, or X-DatComs 400 and ComDocs 900 within the DW Protocol service area, assists ComDoc 900 to ComDoc 900 data links within the DW Protocol service area, manages the voice/data and signaling channels, and effectively connects calls for SEs 600 that are connected to the NE 800. Since the NE 800 must be in radio line-of-sight with the SEs 600 that it services, its location site may be critical in system deployment. An alternative fiber-optic SE 600-NE 800 catastrophic failure network is also an option. A hardware connection between the SE 600 and the NE 800 may substitute for difficult line-of-site deployments. The NE 800 is analogous to a simplified “mobile switching center” or MSC in a cellular or PCS system. While an MSC may be compared to a telephone CO (central office) or TO (toll office) 18, the NE 800 more closely compares to a PBX (Private Branch Exchange), which connects to a CO 18 or TO. The NE 800 enables the wireless communication systems 11, 12 to function independently of an external network; with the AI Network 1300, serving as a catastrophic failure backup routing system.
The wireless communication systems 11, 12 are deployed as networks as shown in FIG. 1. The networks 11, 12 each consists of one or more fixed NE 800 sites and a number of fixed SE 600 sites associated with each NE 800. The networks 11, 12 are essentially the infrastructure required to service mobile handsets 300, ComDocs 900 and X-DatComs 400 in a given geographical area. A network that includes multiple NEs 800 must support the exchange of digital voice, signaling, and data between NEs 800 in the network. The networks 11, 12 shown in FIG. 1, are isolated unless one or more NEs 800 or SEs 600 are connected to a PSTN 19, the Internet (for internet services or voice-over-IP) or to a dedicated fiber optic network 16. With PSTN 19 access, the networks 11, 12 can support calls between isolated networks 11, 12, as well as incoming and outgoing calls with other phones in the PSTN 19. Internet access via internet service providers (ISPs) 15 enable remote system monitoring, data entry, sharing of system databases and voice-over IP, while connection to a dedicated fiber optic cable 14 provides a dedicated fiber optic network 14 between NE's 800, an alternate dedicated fiber optic network 14 signal route between SEs 600 and NEs, or an alternate dedicated fiber optic network 14 signal route between SE 600 and SE 600. In a preferred embodiment, there is no formal or actual connection between the signal extender (SE) 600 and the PSTN 19. The connection is accomplished by giving the SE its own ComDocs 900 waiting for the SE to utilize them wirelessly.
In FIG. 1, the wireless communication system #1, 11 comprises three macrocells, where each macrocell includes a network extender 800 communicating with a number of signal extenders 600 that communicate with a number of handsets 300, ComDocs 900 and X-DatComs 400. The network extenders 800 and the signal extenders 600 are connected together by communication backbones 13. Network extenders 800 may also connect to a PSTN 19 via a trunk line 17 to a central switching office 18. Network extenders 800 may also connect to the Internet via a connection 14 to an Internet service provider 15. Signal Extenders may also connect to a PSTN 19 via backup trunk lines to a central switching office 18. Signal extenders 800 may also connect to the Internet via a connection 14 to an Internet service provider 15. Signal extenders 800 may alternately connect to the PSTN 19 during a catastrophic failure of the NE 800 as suggested by the AI Network 1300 through PSTN-SE Interface 1600. In a preferred embodiment, there is no formal or actual connection between the signal extender (SE) 600 and the PSTN 19. The connection is accomplished by giving the SE its own ComDocs 900 waiting for the SE to utilize them wirelessly.
Therefore, as shown in FIG. 1, wireless communication systems 11, 12 may be interconnected through the Internet 16, PSTN 19 connections, a ComDoc-to-PSTN interface, ComDoc-to-PSTN-Internet interface, an X-DatCom 400-to-PSTN interface, an X-DatCom 400-to-PCS network 1500 interface, an X-DatCom 400-to-ComDoc interface, a Handset 300-to-X-DatCom 400 interface, a PSTN 19-to-X-DatCom 400 interface, an X-DatCom 400-to-PSTN-to-External Device 1400 interface or an X-DatComs 400-to-PSTN-Internet interface. Numerous other permutations of routing and connections are also possible but not shown specifically.
The Artificial Intelligence (AI) Computer Network 1300 is part of the Artificial Intelligence-based Distributive Routing System which is resident but decentralized in the system. The system comprises a network of computers having a computer residing in each signal extender and each computer having an Artificial Intelligence software program to gather information regarding timely calling data, routing and wireless device use histories and to analyze the information for recommending or executing alternative communication paths within the entire system of the signal extenders and the network extender during excessive peak hours loading of the network extender or during a catastrophic failure of any signal extender or the network extender. For example, the AI system learns by constantly polling all wireless devices for usage, polls the ComDocs several times a day and night to ask if the landline connected to it is in use and constantly watches the NE to determine call loading and signs of failure. A limit may also be set on the number of calls that the NE is handling that in turn triggers the AI system to recommend to the system wireless sets with ComDocs use them or to SEs with dedicated ComDocs and PSTN lines to take the load off the NE. In a preferred embodiment, the limit is 95% capacity at the NE. The information obtained by the AI system can also be used to re-direct the communication paths to optimize call loads of the signal extenders and network extenders in the system, or to bypass any failed signal extenders or network extenders in the system.
The AI system may further report the day's gathered information to each of the other signal extenders for comparative analysis and making logical suggestions to the handsets, communications docking bays and External Data Communications Modules operating within the system. The Artificial Intelligence System may further be programmed to gather relevant data from remotely placed external data communications modules by means of a wireless protocol established for operations of the system. The wireless protocol is established for operations of the system interfaced with a network including but not limited to four Public Switch Telephone Network lines, a fiber optic communication link, a coaxial cable, a public TCP/IP network, a directional emergency tower to tower microwave link, a satellite communication link, a communication docking bay routed to other destinations and data collection devices selected by the Artificial Intelligence System.
Turning now to FIG. 2, FIG. 2 shows a relationship between adjacent macrocells 22 in a cellular topology 20. The fixed NE 800 and SE 600 sites of a wireless communication system are organized in a cellular topology 20 similar to the tower arrangement in a cellular or PCS system. The cellular topology 20 promotes frequency reuse and is effective in installation planning. In the present invention, two cell types are defined: microcells 32 and macrocells 22 containing multiple microcells 32. The microcell 32 is the basic building block, and the macrocell 22 is typically a group of 21 microcells 32 as shown in FIG. 2.
Turning now to FIG. 3, FIG. 3 shows a relationship between adjacent microcells 32 in a macrocell topology 30. A SE 600 is central to each microcell 32, while an NE 800 is central to each macrocell 22. Nine different microcell types are defined, designated A1–3, B1–3, and C1–3, for the purpose of frequency division multiple access (FDMA). Each microcell type uses a common subset of frequencies. No two microcells 32 of the same type are ever adjacent, even when macrocells 32 are adjacent.
Turning now to FIG. 4, FIG. 4 shows the radio frequency spectrum 40 used by the present wireless communication system. The present wireless communication system utilizes the Broadband PCS radio frequency spectrum, licensed in the United States by the FCC (Federal Communications Commission). The frequency range that it covers is between 1850 megahertz and 1990 megahertz, and includes PCS low band 42 and PCS high band 44. Licenses must be acquired for one or more PCS blocks, A through F, shown in FIG. 4.
Turning now to FIG. 5, FIG. 5 shows the DW radio frequency protocol 50 used by the present wireless communication system. The DW protocol 50 utilizes the PCS spectrum as illustrated in FIG. 5. The PCS low band 42 is reserved for SE 600 receive frequencies, and the high band 44 for SE 600 transmit frequencies. Half of each band is reserved for signals between the SEs 600 and the handsets 300, between SE's 600 and ComDocs 900, or between SE's 600 and X-DatComs 400 with the other half for signals between the SEs 600 and the NE 800. Regarding the wireless communications system depicted in FIG. 5, a ComDoc 900 communicates with a SE 600 in the same manner that a handset 300 communicates with a SE 600 and an X-DatCom 400 also communicates with a SE 600 in the same manner that a handset 300 communicates with a SE 600. With duplex filtering and 80-MHz separation between the low band 42 and high band 44, the SE 600 can simultaneously receive and transmit signals without compromising receiver sensitivity. This frequency plan allows calls to take place asynchronously, which simplifies the design. Although many possible timing architectures may be used in the present wireless communication system, an asynchronous system architecture was selected to provide the best fit to the key requirements of cost, range, user density and human limitations to perceptibility of delayed audio signals within the DW Protocol network. Asynchronous operation of the present wireless communication system allows greater flexibility in system geographic layout, simpler digital protocol, and channel separation structure. Conventional digital cellular and PCS systems are designed such that synchronous operation is a necessity. CDMA cellular/PCS systems require synchronous operation to insure demodulation and precise coordination of power control and TDMA cellular/PCS systems require synchronous operation to prevent time slot interference. Synchronous operation allows the system design to make very efficient use of the assigned spectrum (high user density) for a given size geographic area for a trade-offs in system complexity, cost, flexibility and limits on relaying signals within a cell site's control. The present wireless communication system has lower density requirements (rural environment), so the advantages of asynchronous operation became very beneficial to the required cost effectiveness of the present system design. Human physiology is unable to detect delays in an audio signal of up to 80 milliseconds. Advantages of this asynchronous operation becomes very beneficial when sending signals from SE 600 to SE 600 over great distances that approach this 80 millisecond human threshold of detectability. Estimates by wireless engineers are in excess of 1,000 miles for the relaying of voice signals within this asynchronous system before the user becomes aware of a delay in the audio. No synchronous PCS system can even approach distances as great as 27 miles when relaying/repeating audio signals within a given cell tower's control; restricted by the speed of light and the absolute requirement to stay synchronized with the tower from which the audio signal derived and in which the handset is registered operationally. FIG. 5 also shows how the PCS bands are further divided into sub-bands dedicated for each of the 9 microcell types. Each microcell (see 32, FIG. 3) uses the sub-bands assigned for its particular type (alpha-numeric designator A1, A2, A3, B1, B2, B3, C1, C2, or C3) in order to preclude interference with adjacent microcells (since adjacent microcells are never of the same type). The microcell sub-bands are 825 kHz wide for PCS blocks ABC, and 275 kHz wide for blocks DEF. The definition of 9 microcell types provides two additional non-adjacent types beyond the minimum 7 that are required for a hexagonal cell layout with FDMA shown in FIG. 3. For a microcell 32 in the cell pattern illustrated in FIG. 3, the additional two non-adjacent types are the other two alpha designators with the same numeric designator. For example, the sub-bands for microcell types A2 and C2 are not used in the microcells adjacent to microcell B2. Sub-bands A1ML, A2ML, A3ML, B1ML, B2ML, B3ML, C1ML, C2ML and C3ML are assigned to communication from a handset 300, a ComDoc 900 or an X-DatCom 400 to a signal extender 600. Sub-bands A1MH, A2MH, A3MH, B1MH, B2MH, B3MH, C1MH, C2MH and C3MH are assigned to communication from a signal extender 600 to a handset 300, a ComDoc 900 or an X-DatCom 400. Sub-bands A1XL, A2XL, A3XL, B1XL, B2XL, B3XL, C1XL, C2XL and C3XL are assigned to communication from a network extender 800 to a signal extender 600. Sub-bands A1XH, A2XH, A3XH, B1XH, B2XH, B3XH, C1XH, C2XH and C3XH are assigned to communication from a signal extender 600 to a network extender 800.
Turning now to FIG. 6, FIG. 6 shows examples of signal flow in diagram 60 of communication paths 61, 62, 63, 64, 65, 66, 67, 68, 61a, 64a, 65a, 68a, 15x, 1400x and 19x. These paths illustrate signal flow between a handset 302, a ComDoc 901, located in two different microcells B1, 73 and B2, 75, respectively. These paths also illustrate a path of signal flow between a handset 301 and an X-DatCom 400; further connecting to a remote device 1400 via a dedicated connection 1400x; with handset 301 and X-DatCom 400 located in two different microcells B1, 73 and B2, 75, respectively. These paths further illustrate a path of signal flow between a handset 301, a signal extender 601, a network extender 801, a signal extender 602, a remotely placed X-DatCom 400, the PSTN 19, on to some designated landline number; with handset 301 and X-DatCom 400 located in two different microcells B1, 73 and B2, 75, respectively. Diagram 60 provides illustration of additional paths of signal flow between an X-DatCom 400, a signal extender, a network extender 800 and an Internet ISP. It also shows an example of a signal flow between handset 301, a signal extender 601, a ComDoc 901, located in the same microcell B1; interconnecting to an ISP 15, externally via a Cable 15x. Additional paths are further illustrated through the signal flow between a handset 302, a signal extender 602, an X-DatCom 400 and the PSTN 19; indicative of a path chosen to signal an X-DatCom 400, via the handset 302, to download data collected by the X-DatCom 400, to a remote location attached to the PSTN, 19 but not shown.

Turning now to FIG. 7, FIG. 7 shows a signal flow diagram 70 of communication paths 76, 76a, 76b, 77, 77a, 77b, 77c, 77d, and 77e between an X-DatCom 409, a computer 305, a handset 303, a signal extender 603, a ComDoc 903, alternately a route to a handset 907, alternately a route to the PSTN, alternately a route to a computer 909, further on from the computer 909 to a X-DatCom 400, further on from the X-DatCom 400 to a remote device 1401; within the same microcell C3, 71. The signal flow diagram 60 illustrates an example of frequency usage in the system. In FIG. 7, a local path call is shown between the handset 303 and the ComDoc 903 in the same microcell C3, 71, in which case no central NE switching is required. Note in FIG. 7 that the sub-band used for the local path calls differs from the microcell type, but is usable because it is one of the two non-adjacent microcell types (i.e., different alpha, but same numeric designator). The communication path from the handset 303 to the signal extender 603 is carried on sub-band B3ML 76, and the communication from the signal extender 603 to the ComDoc 903 is carried on sub-band B3MH 77. The communication path from the ComDoc 903 to the signal extender 603 is carried on sub-band B3ML 76, and the communication from the signal extender 603 to the ComDoc 903 is carried on sub-band B3MH 77. FIG. 7 also shows examples of other communication channels used to connected the X-DatCom 409, path 76, to the handset 303 via path 76a, through the signal extender 603, to the ComDoc 903, alternately to the PSTN 905 via path 77a, alternately to handset 907 via path 77b, alternately to computer 909 via path 77c, further on to X-DatCom 400 via path 77d, further on to remote device 1401 via path 77e. General control and operational state control have also been achieved over X-DatCom 400 by this network link via the computer 909. The connection between ComDoc 903 and computer 909 is achieved via a standard computer data cable.
FIGS. 6 and 7 depict the physical relationships between handset 301, 303, and 907, ComDocs 901, 903, signal extenders 601-603, network extender 801, X-DatCom 400, and 409, remote devices 1400 and 1401, computers 305 and 909; microcells 71, 73, 74, and 75 and a macrocell. A macrocell is able to utilize the full amount of PCS spectrum that is licensed. This is achieved by including at least one microcell of each of the 9 types (A1–3, B1–3, C1–3) in a macrocell, as shown in FIG. 3. In addition, spectrum may be reused within a macrocell among non-adjacent microcells and through the use of directional antennas for the SE-to-NE communication links, which are between fixed sites. Spectrum may also be preserved by utilizing direct fiber optic connections between individual SE's and between SE's and NE's. When all connections between SE's and NE's are by direct fiber optic connection, the spectrum reserved for SE to NE communication can be utilized by wireless devices communicating exclusively with SE's.
The radio frequency (RF) waveform within the DW protocol system is produced using GMSK (Gaussian Minimum Shift Keying) modulation and a data rate of 16 kbps. Baseband filtering limits the 3-dB channel bandwidth to 12.5 kHz. The resultant waveform is a “constant envelope” type, meaning that there is no intended amplitude modulation. The wireless communication system RF coverage and range depend upon the RF parameters of the system (frequency, bandwidth, transmit power, receive sensitivity, antenna gain, etc.), the radio horizon, and the amount of signal occlusion in the line-of-sight between the SE and handset or other such wireless devices found within the DW Protocol system. The RF parameters are specified so that the radio horizon is normally the limiting factor. The radio horizon is a function of the antenna heights and curvature of the earth. As an example, an SE antenna on top of a 100-foot tower can “see” handsets, or other such wireless devices, located out to about 14 miles actual ground distance from the base of the tower. Terrain and man-made structures present the potential for signal occlusions, i.e., non-line-of-sight conditions, which reduce effective coverage and range. Urban propagation models for RF signals show a significant decrease in range compared to clear line-of-sight conditions. For example, the RF conditions that yield 253 miles of range when operated with a clear line-of-sight yield only 4 miles with the urban model.
For systems other than the PCS bands, higher or lower frequencies in the magnetic spectrum yield significantly different characteristics, such as when utilized for DW Protocol transmissions, which is frequency independent.
The deployment of the wireless communication system in rural areas alleviates the potential for urban occlusions, but terrain is still a factor. Microcell/macrocell layout and SE/NE antenna site selection will be required for each installation based on careful planning, consideration, and test of the propagation conditions and physical constraints of the geographical area. The use of the 1.9-GHz PCS spectrum affects the range, amount of multipath, and signal penetration capability compared to other frequency bands such as VHF and UHF, and therefore must be considered in site layout and planning.
The channelization protocol includes elements of control (signaling) and data (voice/data). The available RF spectrum is broken down into voice/data and signaling channels as shown in Table 1, which shows the number of channels per microcell per PCS block.

Note that the total number of extended plus local channels may not be available for simultaneous use. A minimum total of 96 channels is required. Channels are comprised of a transmit/receive pair of frequencies separated by 80 MHz. The handset uplink (handset to NE) uses two channel halves, one for handset to SE, and one for SE to NE. Similarly, the handset downlink (NE to handset) uses the other halves of the same two channels, one for NE to SE, and one for SE to handset. The SE provides the necessary frequency translation for both the uplink and downlink. The handset and NE channel pairs are different, but 80 MHz separates each pair. The fixed 80-MHz offset is built into the handset and NE transceiver designs to allow for microsecond switching between receive and transmit functions. Local path calls, as shown in FIG. 7, present an exception to the channel concept described in the preceding discussion because these calls do not have an uplink/downlink with the NE. As a result, they use only one channel pair, which is shared between the two handsets. The SE is still required to provide the frequency translation.
Turning now to FIG. 8, FIG. 8 shows voice or data frames and packets 80 between a handset and a ComDoc. A number of voice data channels (VDCs) are used in each microcell to carry voice/data call traffic in the wireless communication system. Each VDC is dedicated to a single call (i.e., voice/data channels are not multiplexed) to simplify the design. Two VDC types are defined, extended path and local path, as illustrated in FIGS. 6 and 7. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for each extended VDC (i.e., uplink from handsets to SE, uplink from SE to NE, downlink from NE to SE, and downlink from SE to handsets). In contrast, the frequencies for the local VDCs are allocated from the sub-band spectrum of one of the two non-adjacent microcell types, which are identified by different alpha, but same numeric designator. For example, in microcell type B2, the local VDCs use the frequencies from microcell type A2 or C2. Since these cells are non-adjacent, interference is precluded. It is noted that for the local VDC, only two fixed physical frequencies are required (i.e., uplink from handsets to SE, downlink from SE to handsets) since the NE is not utilized. Local VDCs are contained within the microcell, while extended VDCs are connected through the NE to other microcells, macrocells, and/or the PSTN. Calls between handsets located in the same microcell use local VDCs to increase system capacity by reducing the number of calls switched through the NE. The use of separate sub-band blocks for extended and local path/data channels allows the SE to relay the extended VDCs to the NE, and the local VDCs back within the microcell for receipt by other handsets. The number of VDCs in a microcell depends on the amount of spectrum that is available: 38 VDCs (19 local, 19 extended) in a 5-MHz block (D, E, or F) or 96 VDCs (63 max local, 63 max extended) in a 15-MHz block (A, B, or C). One VDC is required for each call in a microcell. Extended VDCs support one handset or ComDoc. Local VDCs support two handsets, or a handset and a ComDoc, but still only one call. The advantage of the local VDC is that the handsets share the channel (which saves a VDC), and the complementary channels for the uplink/downlink are not required (which saves two more VDCs). The result is one channel pair required versus four channel pairs for an extended path call. Whenever one of the handsets on a local VDC call leaves the microcell, the call must be handed off to separate extended VDCs for each handset. The VDC protocol is half-duplex on the physical channel, but is effectively full duplex from the user's perspective. This is achieved by buffering and encoding the digitized voice data, and transmitting it in packets at a higher data rate than is required for real-time decoding. As a result, the handset is able to toggle back and forth between its transmit and receive functions at an even rate (50% transmit, 50% receive). This alternating transmit-receive “ping-pong” approach is illustrated in FIG. 8. An advantage of the ping-pong approach is that full-duplex transmit and receive functionality is not required of the handset. Consequently the handset architecture uses a transmit/receive (TR) switch instead of a duplexer, to significantly reduce cost, size, and weight. A 40 ms voice frame (20 ms transmit window, 20 ms receive window) will be utilized as shown in FIG. 8 based on the vocoder (voice encoder/decoder) packet size. The frame length sets the minimum buffering delay since the voice signal must be fully acquired in real-time and packetized before transmission. Delays due to frame lengths much above 40 ms may become perceptible to the user. On the other hand, short frame lengths much less than 40 ms reduce efficiency and are not desired. Some call maintenance actions require that the handset drop a voice frame. This may be perceptible to the user but will be an infrequent occurrence. This approach allows the handset to use only one transmitter to conserve size, weight, power consumption, and cost. A small amount of in-band signaling data is available on the VDC, for example, DTMF (dual-tone multi-frequency) codes for digits dialed during a call, and call progress codes including hangup indication. This in-band signaling data is shown on FIG. 8, labeled “OH” for overhead data. As shown in FIG. 8, 40 ms encoded voice frames 81 are compressed into a transmit window voice packet 82 and transmitted from the handset with overhead data OH. The voice and overhead packets are received as a received window voice packets 83 by the ComDoc and decompressed into 40 ms decoded voice frames 84. The reverse of this process is being carried on by the ComDoc compressing and transmitting to the handset where the voice frame is decompressed and decoded by the handset.
Turning now to FIG. 8a, FIG. 8a shows voice or data frames and packets 80a between a handset and an X-DatCom. A number of voice data channels (VDCs) are used in each microcell to carry voice/data call traffic in the wireless communication system. Each VDC is dedicated to a single call (i.e., voice/data channels are not multiplexed) to simplify the design. Two VDC types are defined, extended path and local path, as illustrated in FIGS. 6 and 7. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for each extended VDC (i.e., uplink from handsets to SE, uplink from SE to NE, downlink from NE to SE, and downlink from SE to handsets). In contrast, the frequencies for the local VDCs are allocated from the sub-band spectrum of one of the two non-adjacent microcell types, which are identified by different alpha, but same numeric designator. For example, in microcell type B2, the local VDCs use the frequencies from microcell type A2 or C2. Since these cells are non-adjacent, interference is precluded. It is noted that for the local VDC, only two fixed physical frequencies are required (i.e., uplink from handsets to SE, downlink from SE to handsets) since the NE is not utilized. Local VDCs are contained within the microcell, while extended VDCs are connected through the NE to other microcells, macrocells, and/or the PSTN. Calls between handsets located in the same microcell use local VDCs to increase system capacity by reducing the number of calls switched through the NE. The use of separate sub-band blocks for extended and local path/data channels allows the SE to relay the extended VDCs to the NE, and the local VDCs back within the microcell for receipt by other handsets. The number of VDCs in a microcell depends on the amount of spectrum that is available: 38 VDCs (19 local, 19 extended) in a 5-MHz block (D, E, or F) or 96 VDCs (63 max local, 63 max extended) in a 15-MHz block (A, B, or C). One VDC is required for each call in a microcell. Extended VDCs support one handset or X-DatCom. Local VDCs support two handsets, or a handset and a X-DatCom, but still only one call. The advantage of the local VDC is that the handsets share the channel (which saves a VDC), and the complementary channels for the uplink/downlink are not required (which saves two more VDCs). The result is one channel pair required versus four channel pairs for an extended path call. Whenever one of the handsets on a local VDC call leaves the microcell, the call must be handed off to separate extended VDCs for each handset. The VDC protocol is half-duplex on the physical channel, but is effectively full duplex from the user's perspective. This is achieved by buffering and encoding the digitized voice data, and transmitting it in packets at a higher data rate than is required for real-time decoding. As a result, the handset (or X-DatCom) is able to toggle back and forth between its transmit and receive functions at an even rate (50% transmit, 50% receive). This alternating transmit-receive “ping-pong” approach is illustrated in FIG. 8a. An advantage of the ping-pong approach is that full-duplex transmit and receive functionality is not required of the handset. Consequently the handset architecture uses a transmit/receive (TR) switch instead of a duplexer, to significantly reduce cost, size, and weight. A 40 ms voice frame (20 ms transmit window, 20 ms receive window) will be utilized as shown in FIG. 8a based on the vocoder (voice encoder/decoder) packet size. The frame length sets the minimum buffering delay since the voice signal must be fully acquired in real-time and packetized before transmission. Delays due to frame lengths much above 40 ms may become perceptible to the user. On the other hand, short frame lengths much less than 40 ms reduce efficiency and are not desired. Some call maintenance actions require that the handset drop a voice frame. This may be perceptible to the user but will be an infrequent occurrence. The upper limit in human perceptibility is 80 milliseconds. This approach allows the handset to use only one transmitter to conserve size, weight, power consumption, and cost. A small amount of in-band signaling data is available on the VDC, for example, DTMF (dual-tone multi-frequency) codes for digits dialed during a call, and call progress codes including hangup indication. This in-band signaling data is shown on FIG. 8a, labeled “OH” for overhead data. As shown in FIG. 8a, 40 ms encoded voice frames 81a are compressed into a transmit window voice packet 82a and transmitted from the handset with overhead data OH. The voice and overhead packets are received as a received window voice packets 83a by the X-DatCom and decompressed into 40 ms decoded voice frames 84a. The reverse of this process is being carried on by the X-DatCom compressing and transmitting to the handset where the voice frame is decompressed and decoded by the handset.
Turning now to FIG. 8b, FIG. 8b shows voice or data frames and packets 80b between a ComDoc and an X-DatCom. A number of voice data channels (VDCs) are used in each microcell to carry voice/data call traffic in the wireless communication system. Each VDC is dedicated to a single call (i.e., voice/data channels are not multiplexed) to simplify the design. Two VDC types are defined, extended path and local path, as illustrated in FIGS. 6 and 7. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for each extended VDC (i.e., uplink from X-DatComs to SE, uplink from SE to NE, downlink from NE to SE, and downlink from SE to ComDocs). In contrast, the frequencies for the local VDCs are allocated from the sub-band spectrum of one of the two non-adjacent microcell types, which are identified by different alpha, but same numeric designator. For example, in microcell type B2, the local VDCs use the frequencies from microcell type A2 or C2. Since these cells are non-adjacent, interference is precluded. It is noted that for the local VDC, only two fixed physical frequencies are required (i.e., uplink from X-DatComs to SE, downlink from SE to ComDocs) since the NE is not utilized. Local VDCs are contained within the microcell, while extended VDCs are connected through the NE to other microcells, macrocells, and/or the PSTN. Calls between handsets, X-DatComs or ComDocs located in the same microcell use local VDCs to increase system capacity by reducing the number of calls switched through the NE. The use of separate sub-band blocks for extended and local path/data channels allows the SE to relay the extended VDCs to the NE, and the local VDCs back within the microcell for receipt by other DW wireless devices. The number of VDCs in a microcell depends on the amount of spectrum that is available: 38 VDCs (19 local, 19 extended) in a 5-MHz block (D, E, or F) or 96 VDCs (63 max local, 63 max extended) in a 15-MHz block (A, B, or C). One VDC is required for each call in a microcell. Extended VDCs support one handset or X-DatCom. Local VDCs support two handsets, a handset and an X-DatCom, a ComDoc and an X-DatCom, but still only one call. The advantage of the local VDC is that the DW wireless devices share the channel (which saves a VDC), and the complementary channels for the uplink/downlink are not required (which saves two more VDCs). The result is one channel pair required versus four channel pairs for an extended path call. Whenever one of the handsets on a local VDC call leaves the microcell, the call must be handed off to separate extended VDCs for each handset.

This is achieved by buffering and encoding the digitized voice data, and transmitting it in packets at a higher data rate than is required for real-time decoding. As a result, the handset is able to toggle back and forth between its transmit and receive functions at an even rate (50% transmit, 50% receive). This alternating transmit-receive “ping-pong” approach is illustrated in FIG. 8. An advantage of the ping-pong approach is that full-duplex transmit and receive functionality is not required of the handset (X-DatCom-ComDoc). Consequently the DW wireless device architecture uses a transmit/receive (TR) switch instead of a duplexer, to significantly reduce cost, size, and weight. A 40 ms voice frame (20 ms transmit window, 20 ms receive window) will be utilized as shown in FIG. 8b based on the vocoder (voice encoder/decoder) packet size. The frame length sets the minimum buffering delay since the voice signal must be fully acquired in real-time and packetized before transmission. Delays due to frame lengths much above 40 ms may become perceptible to the user. On the other hand, short frame lengths much less than 40 ms reduce efficiency and are not desired.

This in-band signaling data is shown on FIG. 8b, labeled “OH” for overhead data. As shown in FIG. 8b, 40 ms encoded voice frames 81b are compressed into a transmit window voice packet 82b and transmitted from the ComDoc with overhead data OH. The voice and overhead packets are received as a received window voice packets 83b by the X-DatCom and decompressed into 40 ms decoded voice frames 84b. The reverse of this process is being carried on by the X-DatCom compressing and transmitting to the ComDoc where the voice frame is decompressed and decoded by the ComDoc.
Turning now to FIG. 8c, FIG. 8c shows voice or data frames and packets 80c between a X-DatCom and NE. A number of voice data channels (VDCs) are used in each microcell to carry voice/data call traffic in the wireless communication system. Each VDC is dedicated to a single call (i.e., voice/data channels are not multiplexed) to simplify the design. Two VDC types are defined, extended path and local path, as illustrated in FIGS. 6 and 7. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for each extended VDC (i.e., uplink from X-DatComs to SE and an uplink from SE to NE. In contrast, the frequencies for the local VDCs are allocated from the sub-band spectrum of one of the two non-adjacent microcell types, which are identified by different alpha, but same numeric designator. For example, in microcell type B2, the local VDCs use the frequencies from microcell type A2 or C2. Since these cells are non-adjacent, interference is precluded. It is noted that for the local VDC, only two fixed physical frequencies are required (i.e., uplink from X-DatComs to SE, downlink from SE to ComDocs) since the NE is not utilized. Local VDCs are contained within the microcell, while extended VDCs are connected through the NE to other microcells, macrocells, and/or the PSTN. Calls between handsets, X-DatComs or ComDocs located in the same microcell use local VDCs to increase system capacity by reducing the number of calls switched through the NE. The use of separate sub-band blocks for extended and local path/data channels allows the SE to relay the extended VDCs to the NE, and the local VDCs back within the microcell for receipt by other DW wireless devices. The number of VDCs in a microcell depends on the amount of spectrum that is available: 38 VDCs (19 local, 19 extended) in a 5-MHz block (D, E, or F) or 96 VDCs (63 max local, 63 max extended) in a 15-MHz block (A, B, or C). One VDC is required for each call in a microcell. Extended VDCs support one handset or X-DatCom. Local VDCs support two handsets, a handset and an X-DatCom, a ComDoc and an X-DatCom, but still only one call. The advantage of the local VDC is that the DW wireless devices share the channel (which saves a VDC), and the complementary channels for the uplink/downlink are not required (which saves two more VDCs). The result is one channel pair required versus four channel pairs for an extended path call. Whenever one of the handsets on a local VDC call leaves the microcell, the call must be handed off to separate extended VDCs for each handset. The VDC protocol is half-duplex on the physical channel, but is effectively full duplex from the user's perspective. This is achieved by buffering and encoding the digitized voice data, and transmitting it in packets at a higher data rate than is required for real-time decoding. As a result, the handset is able to toggle back and forth between its transmit and receive functions at an even rate (50% transmit, 50% receive). This alternating transmit-receive “ping-pong” approach is illustrated in FIG. 8c. An advantage of the ping-pong approach is that full-duplex transmit and receive functionality is not required of the handset (X-DatCom-ComDoc). Consequently the DW wireless device architecture uses a transmit/receive (TR) switch instead of a duplexer, to significantly reduce cost, size, and weight. A 40 ms voice frame (20 ms transmit window, 20 ms receive window) will be utilized as shown in FIG. 8c based on the vocoder (voice encoder/decoder) packet size. The frame length sets the minimum buffering delay since the voice signal must be fully acquired in real-time and packetized before transmission. Delays due to frame lengths much above 40 ms may become perceptible to the user. On the other hand, short frame lengths much less than 40 ms reduce efficiency and are not desired. Some call maintenance actions require that the DW wireless device drop a voice frame. This may be perceptible to the user but will be an infrequent occurrence. This approach allows the handset to use only one transmitter to conserve size, weight, power consumption, and cost. A small amount of in-band signaling data is available on the VDC, for example, DTMF (dual-tone multi-frequency) codes for digits dialed during a call, and call progress codes including hangup indication. This in-band signaling data is shown on FIG. 8c, labeled “OH” for overhead data. As shown in FIG. 8c, 40 ms encoded voice frames 81c are compressed into a transmit window voice packet 82c and transmitted from the X-DatCom with overhead data OH. The voice and overhead packets are received as a received window voice packets 83c by the NE and decompressed into 40 ms decoded voice frames 84c. The reverse of this process is being carried on by the NE compressing and transmitting to the X-DatCom where the voice frame is decompressed and decoded by the X-DatCom.
Turning now to FIG. 9, FIG. 9 shows four channel Contiguous Channel Acquisition Protocol (CCAP) data frames and packets transmitting and receiving between a handset linked to Laptop Computer and another handset linked to Laptop Computer. As shown in FIG. 9, 40 ms encoded voice frames 91 are compressed into a transmit window data packet 92, which comprises four contiguous voice channels, and transmitted from the handset with overhead data OH. The data and overhead packets are received as a received window data packets 93 by the second handset-computer and decompressed into 40 ms decoded data frames 94. The reverse of this process is being carried on by the handset-computer compressing and transmitting to the first handset-computer where the data frame is decompressed and decoded by the first handset. By using four contiguous voice channels to transmit data, the channel bandwidth is increased four-fold, or up to approximately 56 kbps. This feature enables a laptop computer connected to a mobile handset to communicate at a 56 kbps rate with a second computer connected to another handset, as shown here in FIG. 9. Other communication paths are also possible, as in FIG. 7 where such a laptop is connected to a mobile handset communicating via a ComDoc and a PSTN to an Internet service provider. If twelve contiguous voice channels were available to transmit data using a CCAP+ protocol, the channel bandwidth may be increased twelve-fold, or up to approximately 250 kbps. The added bandwidths are obtained by adding adjacent channels together to obtain a higher data rate.
Turning now to FIG. 9a, FIG. 9a shows four channel Contiguous Channel Acquisition Protocol (CCAP) data frames and packets transmitting and receiving between a ComDoc linked to Laptop Computer and X-DatCom. As shown in FIG. 9a, 40 ms encoded voice frames 91a are compressed into a transmit window data packet 92a, which comprises four contiguous voice channels, and transmitted from the ComDoc with overhead data OH. The data and overhead packets are received as a received window data packets 93a by the X-DatCom and decompressed into 40 ms decoded data frames 94a. The reverse of this process is being carried on by the X-DatCom compressing and transmitting to the ComDoc where the data frame is decompressed and decoded by the ComDoc. By using four contiguous voice channels to transmit data, the channel bandwidth is increased four-fold, or up to approximately 56 kbps. This feature enables a laptop computer connected to a mobile handset to communicate at a 56 kbps rate with a second computer connected to another handset, as shown here in FIG. 9a. Other communication paths are also possible, as in FIG. 7 where such a laptop is connected to a mobile handset communicating via a ComDoc and a PSTN to an Internet service provider. If twelve contiguous voice channels were available to transmit data using a CCAP+ protocol, the channel bandwidth may be increased twelve-fold, or up to approximately 250 kbps. The added bandwidths are obtained by adding adjacent channels together to obtain a higher data rate.
Turning now to FIG. 9b, FIG. 9b shows four channel Contiguous Channel Acquisition Protocol (CCAP) data frames and packets between an X-DatCom and a Network Extender. As shown in FIG. 9b, 40 ms encoded voice frames 91b are compressed into a transmit window data packet 92b, which comprises four contiguous voice channels, and transmitted from the X-DatCom with overhead data OH. The data and overhead packets are received as a received window data packets 93b by the NE and decompressed into 40 ms decoded data frames 94b. The reverse of this process is being carried on by the NE compressing and transmitting to the X-DatCom where the data frame is decompressed and decoded by the X-DatCom. By using four contiguous voice channels to transmit data, the channel bandwidth is increased four-fold, or up to approximately 56 kbps. This feature enables a laptop computer connected to a mobile handset to communicate at a 56 kbps rate with a desktop computer connected to a ComDoc, as shown in FIG. 7. Other communication paths are also possible, such as a laptop connected to a mobile handset communicating via a ComDoc and a PSTN to an Internet service provider. If twelve contiguous voice channels were available to transmit data using a CCAP+ protocol, the channel bandwidth may be increased twelve-fold, or up to approximately 250 kbps. The added bandwidths are obtained by adding adjacent channels together to obtain a higher data rate.
Turning now to FIG. 10, FIG. 10 shows reference channel framing 100. A single, shared Reference Channel (RC) is used in each microcell for broadcast to handsets, ComDocs and X-DatComs. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for the RC (i.e., uplink from handsets, ComDocs or X-DatComs to SE, uplink from SE to NE, downlink from NE to SE, and downlink from SE to handsets), although the handset, ComDoc and X-DatCom uplink is not utilized. The handsets, ComDocs and X-DatComs read the RC to identify the presence of service. Without the RC, the handsets, ComDocs and X-DatComs are inoperable. Besides identifying wireless communication system service, the RC is used by the handsets, ComDocs and X-DatComs to adjust its internal frequency reference (typically a voltage-controlled temperature-compensated crystal oscillator or VCTCXO). This adjustment capability allows the handsets, ComDocs and X-DatComs to achieve increased frequency accuracy and stability and thus improved bit-error performance in demodulation of signals. The following information is also provided to the handset on the RC:
Date and Time
Microcell/Macrocell Identification Code
Handset/ComDoc Attention Codes (supports the CMC, described below)
Broadcast Text Messages
The NE also transmits special commands on the RC downlink that are addressed to the SE rather than the handsets, ComDocs and X-DatComs. These commands are used to remotely enable/disable the SE and assign the microcell type (which sets the frequency sub-blocks for use). Remote control of the microcell type provides system frequency agility. The RC uplink, while not used by the handsets, ComDocs and X-DatComs, is used by the SE for command acknowledgement and status reporting to the NE. There are 9 unique RC frequencies in the wireless communication system, one for each microcell type. Handsets, ComDocs and X-DatComs continually scan the RCs in order to identify the handsets, ComDocs and X-DatComs microcell/macrocell location. This is accomplished by monitoring the RC power levels and reading the microcell/macrocell ID codes. Real-time tracking of handsets, ComDocs and X-DatComs microcell location is important for mobile wireless communication because handsets, ComDocs and X-DatComs are required when handsets, ComDocs and X-DatComs move between microcells. In order to facilitate RC scanning while a call is active, the handsets, ComDocs and X-DatComs architecture includes two parallel receivers; one dedicated to the VDC, and the other dedicated to RC scanning. As shown in FIG. 8, the handset/ComDoc receive function is limited to about 50% duty factor when on a call. The length of the handset/ComDoc receive window is 20 ms based on the vocoder packet size. At the system 16 kbps data rate, 20 ms amounts to 320 bits. In order for the handsets, ComDocs and X-DatComs to ensure receipt of a complete RC message, the message length must be less than 1⁄2 of the handset/ComDoc receive window, or 10 ms, which amounts to 160 bits. In this case, for design purposes, the RC frame is limited to 150 bits. In order to meet this size limitation, data may be distributed across multiple frames resulting in a superframe. For example, broadcast messages are distributed across a superframe with only a few bytes in each frame. Each RC frame within the superframe is repeated four consecutive times before advancing to the next frame; this is referred to as a block. Each block should be the same length as the 40 ms transmit/receive voice frame. Repeating the RC frame transmission four times ensures that a complete 10-ms RC frame will fall within the 20-ms handset/ComDoc receive window no matter where the receive window begins within the 40-ms block. This process is illustrated in FIGS. 9, 9a, 9b which shows examples of several DW Protocol wireless voice frame alignment with RC frames.
Turning now to FIG. 11, FIG. 11 shows a flow diagram 110 for a call initiation channel (CIC) 101, 103, 105, 107 and a call maintenance channel (CMC) 102, 104, 106, 108. A single, shared CIC 101, 103, 105, 107 is used in each microcell for ComDoc 900 registration and call establishment. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for the CIC 101, 103, 105, 107. These four frequencies include an uplink 101 from ComDocs 900 to SE 600, an uplink 103 from SE 600 to NE 800, a downlink 105 from NE 800 to SE 600, and a downlink 107 from SE 600 to ComDocs 900. The CIC uplink 101 is a random access channel whereby the ComDocs 900 within a microcell compete for its use. The ComDocs 900 listen for activity on the CIC downlink 107 from the NE 800 and transmit a call initiation request when the channel is clear. Request messages include the ComDoc address (identification number) and the request information. Response messages include the ComDoc address along with requested information or simple acknowledgement depending on the request. If a downlink response is not received when expected, then the ComDoc 900 will repeat its request following a randomly determined delay period. The delay period is intended to prevent collisions with transmissions from competing ComDocs 900 and handsets on the shared uplink. The following functions are handled on the CIC:
Turning now to FIG. 11a, FIG. 11a shows a flow diagram 110a for a call initiation channel (CIC) 110a, 103a, 105a, 107a and a call maintenance channel (CMC) 102a, 104a, 106a, 108a. A single, shared CIC 110a, 103a, 105a, 107a is used in each microcell for X-DatCom registration and call establishment. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for the CIC 110a, 103a, 105a, 107a. These four frequencies include an uplink 101a from X-DatCom to SE 600, an uplink 103a from SE 600 to NE 800, a downlink 105a from NE 800 to SE 600, and a downlink 107a from SE 600 to X-DatComs 900. The CIC uplink 101a is a random access channel whereby the X-DatComs 900 within a microcell compete for its use. The X-DatComs 900 listen for activity on the CIC downlink 107a from the NE 800 and transmit a call initiation request when the channel is clear. Request messages include the X-DatCom address (identification number) and the request information. Response messages include the X-DatCom address along with requested information or simple acknowledgement depending on the request. If a downlink response is not received when expected, then the X-DatCom will repeat its request following a randomly determined delay period. The delay period is intended to prevent collisions with transmissions from competing handsets ComDocs and X-DatComs on the shared uplink. The following functions are handled on the CIC:
Handset, ComDoc and X-DatCom initial registration to NE 800
Handset, ComDoc and X-DatCom periodic registration refresh to NE 800
Handset, ComDoc and X-DatCom authorization and short id assignment to Handset 300, ComDoc 800 and X-DatCom 400
Call request to NE 800 or to Handset 300, ComDoc 800 and X-DatCom 400
Call frequency assignment to Handset 300, ComDoc 800 and X-DatCom 400
Call progress prior to voice/data channel use to Handset 300, ComDoc 800 and X-DatCom 400
Acknowledgements to NE 800 or to Handset 300, ComDoc 800 and X-DatCom 400
The Handset 300, ComDoc 800 and X-DatCom 400 ID, either an electronic serial number (ESN) or phone number, is 40 bits. When a Handset 300, ComDoc 800 or X-DatCom 400 initially registers in a new microcell, it will be assigned an 8-bit temporary ID for use while registered with that microcell. The shorter ID significantly reduces message lengths on the RC, CIC, and CMC where Handset 300, ComDoc 800 and X-DatCom 400 addresses are required.
Also shown in FIG. 11, a shared Call Maintenance Channel (CMC) 102, 104, 106, 108 is used in each microcell for out-of-band signaling functions once a call has been established. Four fixed physical frequencies from the microcell sub-band spectrum are allocated for the CMC 102, 104, 106, 108. These include an uplink 102 from ComDocs 900 to SE 600, an uplink 104 from SE 600 to NE 800, a downlink 106 from NE 800 to SE 600, and a downlink 108 from SE 600 to ComDocs 900. The CMC uplink 102 is a random access channel whereby the ComDocs 900 and handsets within a microcell compete for its use, just like the CIC uplink. The following functions are handled on the CMC:
Call completion to NE 800
Call handoff request to NE 800
911 position report to NE 800
Call handoff frequency to ComDoc 900
Call waiting notification to ComDoc 900
Voice message notification to ComDoc 900
Text message notification to ComDoc 900
Acknowledgements to NE 800 or to ComDoc 900
When a CMC message is pending for a ComDoc 900, the NE 800 transmits an attention code for the ComDoc 900 on the RC. Since the RC is periodically monitored by the ComDoc 900, even while it is on a call, the ComDoc 900 is able to identify the attention code and then monitor the CMC downlink 108 for the message. When the ComDoc 900 uses the CMC, it drops a 40-ms voice frame in order to use the channel. Consequently, CMC usage must be infrequent and messages should be sized to fit within a single voice frame. If no response is received to a ComDoc request, the request will be retransmitted on another frame after a random delay. Subsequent frames are selected randomly, but the dropping of back-to-back frames is precluded. The above description also applies to FIG. 11a wherein an X-DatCom has been substituted for the ComDoc.
Turning now to FIG. 12, FIG. 12 shows a block diagram 120 of a handset 300. The handset 300 includes a transceiver 310 and antenna 312. The transceiver 310 consists of two receivers, one transmitter, and two programmable frequency synthesizers. The antenna 312 may be integrated into the transceiver, or may be a modular type that plugs into the case. The transceiver transmit power is adjustable in 3 dB steps over a 50 dB range relative to the maximum transmit power. The gain of the transceiver antenna 312 is in the range of 0 to 2.5 dB under controlled conditions. The transceiver 310 is capable of simultaneously receiving and demodulating two signals on independently programmed frequencies. The transceiver architecture includes an 80-MHz offset oscillator to facilitate switching between transmit and receive operations on a single channel pair without needing to re-program a frequency synthesizer. A processor 320 provides centralized control to the handset 300 and includes a digital signal processing (DSP) 322 for demodulating signals, a controller 324 for display/keypad servicing, permanent memory 326, non-volatile memory 328, and volatile memory 330. Firmware is embedded in the processor memory to implement protocols, control the user interfaces for the display, keypad, menus, etc., and control the application program interface (API) for the secondary mode (roaming) protocol. The firmware includes a bootstrap loader that is stored in permanent memory 326 to enable download of the main code. The main code is stored in non-volatile memory 328 so that it is not lost in the absence of power, but can be overwritten by subsequent downloads, e.g., firmware updates. In addition to the main code, there also exist a number of configuration variables that are downloaded to activate the handset 300. These configuration variables set the user's phone number and services subscribed, and are also stored in non-volatile memory. The handset firmware also manages non-volatile user memory for storage of phone book names and numbers, received text messages, and the current operating mode selections (ringer volume/type, beep volume, etc.). The Processor 320 shall have peripheral interfaces to the following elements:
Induction Coupled Data Line: This line attaches to the recharger and may import and export data from a handset via inductive coupling through the environmental package (case). The handset environmental package integrity can be preserved when entering data via the induction coil 390 which is also used for the recharging of the internal batteries. The integrity of the environmental package can be maintained via the induction coil 390 through the case of the environmental package without any external metal contact.
Externally Direct LEDs: These LEDs are included to give the handset user external illumination. The LEDs are in effect, a processor controlled-keypad controlled, flashlight with auto-off features.
Earphone and Microphone Induction Coupled Coils: These internal case coils inductive couple earphone and microphone function to a headset wherein the handset case is of the sealed, water tight variety.
Digital Recorder: This device chip enables the processor to activate a fully functional digital recorder within the handset. Processor interface gives the recorder access to call recording, external-to-the-case recording via the handset microphone or remote activation of recorder functions via another DW Protocol wireless device so coded for such action.
Vocoder 340
E-911 position locator 350
Transceiver 310
Keypad 362
Display 360
Power Manager 370
Roaming Transceiver 380
External Data Interface 390
Miscellaneous controls, including ringer 366, LED 367 and vibrator 368
Permanent memory 326 is utilized for the processor bootstrap firmware and electronic serial number. Each handset 300 contains a unique electronic serial number in permanent memory 326. The serial number permits a minimum of 1 billion unique serial numbers. Bootstrap software is also contained in permanent memory 326 to enable download of the operational software through the handset external data port. The nonvolatile read/write memory 328 is used for storing initialization parameters and phone book data so that battery removal or replacement does not require re-initialization initialization. Each handset contains its phone number in non-volatile memory. The operational software is downloadable to change features or otherwise update the code. The operational software is stored in non-volatile memory 328. The operational software is downloadable using capabilities of the bootstrap software, the external data port 390, and external software. The handset is capable of maintaining user data in non-volatile memory 328, such as phone book entries. The handset includes a vocoder (voice coder/decoder) 340 for processing the digitized voice signals. The vocoder 340 compresses and channel code the digitized voice data in order to meet the voice quality requirement and to enable implementation of the RF and communication protocols. The handset 300 includes a microphone/speaker interface 400 for interfacing a microphone 402 and speaker 404 to other handset components. The handset 300 may accept an external microphone input signal and shall provide an external speaker output signal. The handset 300 includes a power manager 370 to assist in extending battery life. The handset 300 includes a rechargeable battery 410, but is also capable of connection to an external 11–16 Vdc power source through an external power interface 420. The handset 300 includes a roaming transceiver 380 to serve as a secondary or alternate mode to the wireless communication system described. The roaming transceiver implements one or more of the following standard wireless protocols:
PCS CDMA (IS-95)
PCS TDMA (IS-136)
GSM 1900
AMPS
The roaming transceiver 380 includes functions for an antenna, RF transceiver, protocol processing, and vocoder processing. The handset 300 also includes provisions for a position locator function to support the enhanced 911 (E911) requirements if needed.
Turning now to FIG. 13, FIG. 13 shows a block diagram 130 of a signal extender (SE) 600. The SE 600 serves as a signal relay and frequency-translator between handsets 300 and either a NE 800 or other handsets 300. It receives blocks of data in the PCS low band and up-converts them for re-transmission in the PCS high band, as discussed in relation to FIG. 4 through FIG. 7. In this relay process, the SE 600 amplifies the radio frequency signals to increase system range and coverage. The distinguishing feature of the SE 600 is that it does not switch, process, or demodulate individual channels or signals; it is limited in function to relaying blocks of RF spectrum. This functional simplicity is intended to yield low infrastructure cost. The only deviation from this design is to enable access to no more than four PSTN landlines as a routing backup during a Network Extender's catastrophic failure. Even this access is accomplished however, on-site through the wireless connectivity of four ComDocs attached to these landlines. This approach eliminates structural and physical design changes to the signal extenders and keeps costs low. The Artificial Intelligence Distributive Routing Network merely makes suggestions for the SE's to follow: “Route calls through YOUR ComDocs”. More landlines and SE ComDocs would raise the cost; however, never would these additions ever approach the expense of altering the SE design. This approach would also yield the cost benefits of modular expansion should the need arise. Frequency translation is the primary function of the SE 600. Three such translator functions shall be provided as follows:
Translator Type Relay Path Uplink Handset to NE Downlink NE to Handset Local Handset to Handset
Each translator is defined by the center frequency of the input spectrum block, the bandwidth of the block, and an up-conversion offset. The input center frequency is a programmable parameter based on the licensed PCS block (A–F) and the microcell type (A1–3, B1–3, C1–3). The bandwidth and up-conversion offset depend on the PCS block type (ABC or DEF). The three SE translator functions operate with the same bandwidth specifications. The bandwidth is fixed at 275 kHz for 5-MHz PCS block types (DEF) or at 825 for 15-MHz PCS block types (ABC). Signals more than 50 kHz from the band edges are rejected by at least 20 dB relative to the band centers. Signals more than 250 kHz from the band edges are rejected by at least 40 dB relative to the band centers. The three SE translator functions operate with the same frequency accuracy specifications. The input center frequency is accurate to within 2 kHz and the up-conversation offset is accurate to within 500 Hz. The uplink translator 610 translates a block of handset signals to the NE 800. The programmable up-conversion offset is 82.5 MHz for 5-MHz PCS block types (DEF) or 87.5 MHz for 15-MHz PCS block types (ABC). The programmable input center frequency is determined according to the following expression:

Fedge+Fguard+Bandwidth*(Extended+0.5)

where Fedge, Fguard, and Bandwidth are given in Table 2, which shows PCS block parameters for SE 600 frequency translators.

The downlink translator 620 translates a block of signals from a NE 800 to the handsets 300, ComDocs 900 or X-DatComs 400. The programmable up-conversion offset is 77.5 MHz for 5-MHz PCS block types (DEF) or 72.5 MHz for 15-MHz PCS block types (ABC). The programmable input center frequency is determined according to the following expression:

Fmid+Fguard+Bandwidth*(Extended+0.5)

where Fmid, Fguard, and Bandwidth are given in Table 2, and values for Extended are given in Table 3. The local translator 630 translates a block of handset 300, ComDoc 900 or X-DatCom 400 signals to other handsets 300, ComDocs 900 or X-DatComs 400. The up-conversion offset is fixed to 80 MHz. The programmable input center frequency is determined according to the following expression:

Fedge+Fguard+Bandwidth*(Local+0.5)

where Fedge, Fguard, and Bandwidth are given in Table 2, and the value for Local is given in Table 3. The omni antenna 640 is used for omni-directional SE communication with handsets 300 in a microcell. The antenna gain is between 2 dBi and 6 dBi. The directional antenna 650 is used for directional SE communication with the fixed NE site. The antenna gain is 15 dBi, with a front-to-back ratio greater than 25 dB. Duplexers 645, 655 are used to achieve isolation of the antenna signals between the transmit and receive frequency bands. This is required to allow full duplex, i.e., simultaneous transmit and receive, operation of the SE 600. The duplexers 645, 655 provide transmit-receive (and receive-transmit) isolation of at least 80 dB. An uplink low noise amplifier (LNA) 660 is used to receive the handset 300, ComDoc 900 or X-DatCom 400 signals for the uplink translator 610 and local translator 630. The uplink LNA 660 provides a received signal strength indicator (RSSI) 661 output to the SE controller 670, indicating a measure of the aggregate handset 300, ComDoc 900 or X-DatCom 400 transmission activity in the microcell. An uplink power amplifier (PA) 662 is used to transmit the up-converted handset 300, ComDoc 900 or X-DatCom 400 signals to the NE 800. The uplink PA 662 provides an output level of at least 26 dBm across the entire PCS High band (1930 to 1990 MHz). The uplink PA 662 is able to transmit 66 signals at +4 dBm each simultaneously without damage. The uplink PA 662 also provides means for enabling and disabling the output. A downlink low noise amplifier (LNA) 666 is used to receive NE signals for the Downlink Translator 620. A downlink power amplifier (PA) 664 is used to transmit the up-converted handset 300, ComDoc 900 or X-DatCom 400 signals to a NE 800. The downlink PA 664 provides an output level of at least 48 dBm across the entire PCS High band (1930 to 1990 MHz). The downlink PA 664 is able to transmit 99 signals at +25 dBm each simultaneously without damage. The downlink PA 664 also provides means for enabling and disabling the output.
SE power amplifier gains of the three RF paths (uplink, downlink, local) are independently adjustable in 3 dB steps over a 60 dB range from 37 to 97 dB. The gain adjustments are usually made manually during installation based on the microcell size.
A control transceiver 680 is used to receive commands from the NE 800 on the reference channel (RC) downlink, and to transmit acknowledgments and status reports on the RC uplink. The controller 670 is used to program the SE configuration and monitor status for reporting. The controller 670 programs the SE configuration, which consists of the Uplink, Downlink, and Local Translator frequencies, and the Uplink/Downlink PA output on/off state. The following information must be provided to the Controller:
Microcell Type (A1–3, B1–3, C1–3)
PCS Block (A–F)
Desired PA Output State (enabled or disabled)
The SE Translator frequencies are configured based on the microcell type and PCS band as described above. The controller 670 accepts remote commands from the NE 800 via the control transceiver 680 for programming the SE configuration. The controller acknowledges the NE commands. The controller also provides a local port 672 such as an RS-232 for local programming of the configuration in the field from an external laptop computer and for all communications with the resident Artificial Intelligence Distributive Routing Network computer. Upon power-up, the controller 670 sets the SE configuration to the last configuration programmed. The controller periodically transmits status reports to the NE 800 via the control transceiver 680. The following information is included in the status report:
Microcell type (A1–3, B1–3, C1–3)
PCS band (A–F)
PA output state (on or off)
Uplink LNA RSSI reading
Power draw reading
Power source state (external or battery backup)
An uninterruptible power supply (UPS) 690 is used to power the SE equipment and buffer it from the external power grid. In the event of an external power grid outage, the UPS battery backup capability is able to operate the SE 600 for an extended period of time.
Turning now to FIG. 14a and FIG. 14b, FIG. 14a and FIG. 14b show a block diagram 140 of a network extender (NE) 800. The NE 800 is the central switching point for a macrocell, and the external interface to other macrocells, a PSTN and the Internet. The NE 800 incorporates a Global Positioning System (GPS)-based reference source 810 for use in stabilizing the local oscillators in wireless communication system transceivers. The reference output frequency is 10 MHz at the nominal accuracy available from the GPS. The GPS reference source 810 provides a reference frequency used by the NE transceivers and transmitted to the SEs 600 and to handset 300, ComDocs 900 or X-DatComs 400 via the Reference Channel downlink. In addition, the GPS reference source 810 provides date and time information for the macrocell, which is broadcast on the RC downlink. The GPS reference source 810 includes the GPS antenna 814 and a backup reference source suitable to maintain frequency tolerance of RF communication channels. The backup source is automatically selected in the event of GPS signal loss or receiver failure. The reference distributor 812 provides amplification and fan-out, as necessary, to feed the GPS reference signal to the microcell transceiver banks 820. The NE 800 uses directional antennas 824 for communication with the fixed SE sites. The antenna gain is at least 15 dBi with a front-to-back ratio greater than 25 dB. There is one dedicated antenna 824 for each SE 600 supported by the NE 800. Each directional antenna 824 for a microcell is connected to a microcell transceiver bank 820. Each microcell transceiver bank 820 contains a configurable number of transceivers for processing the extended path and signaling channels for the associated microcell. A microcell radio processor is contained within each macrocell receiver bank 820. Microcell servers 822 connect to radios within the microcell transceiver banks 820 to perform control functions associated within a single microcell. The microcell servers 822 communicate with the NE central processor 830 to route and manage calls that connect outside of the microcell. The NE central processor 830 is able to direct the microcell servers 822 to promote a call from local mode to assisted mode, change frequency, or perform a handoff. The microcell servers 822 coordinate control of calls on its microcell, including performing control operations of radios within its microcell transceiver banks 820. The microcell servers 822 accumulate the data for the reference channel and feed it to the radio generating the RC. They also process requests on the CIC and CMC and coordinate the required actions with the radios in its bank and the NE central processor 830. A microcell server 822 may handle multiple transceiver banks. Each microcell server includes an Ethernet interface to connect it to the local area network (LAN) of the NE 800. This LAN connection permits the microcell server 822 to communicate with the NE central processor 830 and the radios to perform its control functions. The microcell servers coordinate communication between the NE central processor 830 and the microcell transceiver banks 820 in use. They also monitor non-responsive radios and dynamically remove them from the active use. The microcell servers are also able to relay status/diagnostic information and command shut down of radios not in an active configuration and to report these configuration changes to the NE central processor 830. They also monitor CIC and CMC requests and relay them to the NE central processor 830 and accept messages for the CIC and CMC and relay them to the microcell transceiver banks 820. The NE central processor 830 coordinates call activity within the NE 800. It processes call requests, call terminations, handoff requests, etc., and downloads control information to microcell servers 822 and communicates with the PSTN interface 860. The NE central processor 830 performs call setup, call tear down, call routing, and call handoff, and is responsible for performing authorization and billing. It is externally configurable over the Internet using an Internet interface 840. The NE Central Processor 830 coordinates call activities for the macrocell, and performs authorization, billing, set up, and diagnostic functions. It coordinates calls originating or terminating within the macrocell. Calls may arrive from handsets 300 within the macrocell, handsets 300 within a distant macrocell with a dedicated link to this macrocell, or from a PSTN. This last case includes calls from a PSTN connection over a dedicated NE-NE link, since not every NE may have a PSTN interface. Signaling from these various sources are evaluated and disposition of the call is determined. Calls may be routed in the following ways: The central process 830 is also connected to a Artificial Intelligence (AI) Network interface 1305 to communicate with the AI network computers 1300 in the Artificial Intelligence-based Distributive Routing System resident in the wireless system.
Within a microcell using the local call mode (no NE handling of voice data)
Within the macrocell (routed through NE switch w/o decompression)
To a linked NE 800 (routed through the NE switch to the linked NE w/o decompression)
To a local PSTN connection (routed through the NE switch to the PSTN gateway with decompression)
To a PSTN connection on a remote NE 800 (routed between NEs without decompression and then to PTSN with decompression)
To a PSTN connection via a dedicated ComDoc associated exclusively with a SE. Multiple line access is possible with more desiccated ComDocs at each SE.
Incoming calls are handled in a similar manner. The signaling is routed separately from the voice data. The NE central processor provides source/destination information to the call terminating devices in the system (microcell servers/radios, PSTN gateway, and remote NE central processor/PSTN gateway). It does not perform the routing function per se. For example, if there are two paths between two linked NEs, the NE central processor 830 depends on the switch to route the call appropriately. The software within the NE central processor 830 maintains a database of subscribers. Authorized users are able to add, delete, check status, and modify records associated with handsets, ComDocs or X-DatComs using the web page. Specifically, the NE central processor 830 shall perform the functions usually associated with the Authorization Center (AC), Home Location Register (HLR), and Visitor Location Register (VLR) of traditional cellular systems. The NE 800 supports storage and programming of activation data using a secure web interface, which provides a way to program the information needed by the NE 800 to activate handsets 300, ComDocs 900 or X-DatComs 400. The NE central processor monitors outgoing calls, and accumulates a billing record of calls that are outside the calling region (i.e., toll calls). The billing record includes the handset placing the call (i.e., account number), the number called, time of call, duration of call, and total charge for the call. This data is uploadable to a central billing system that is external to the NE 800 over a secure communication link. The NE central processor 830 handles set up information that is in addition to the subscriber records described above. The programmable information includes a unique identifier for the NE 800, numbering information for PSTN links, configuration values for the NE switch 850, PSTN interface 860, and NE-NE links 870. It also includes configuration information for the microcells, including frequency block assignments, SE identifiers, encryption keys, and radio bank configuration (e.g., the number of radios in use for a particular bank). The NE central processor supports diagnostic activities of the NE 800.
The Internet interface 840 is the physical hardware that interconnects the NE central processor 830 to an Internet service provider (ISP). The NE 800 contains a mechanism to move (switch) voice/data between different radios, the PSTN, and external NEs. The switch 850 is dynamically reconfigurable to permit calls to be routed automatically to the correct destination. The switch 850 is fast enough to permit calls within a local wireless communication system to operate without perceptible delay. The PSTN interface 860 performs the protocol conversion between the typical PSTN interfaces (T1 or E1) and the internal method used by the NE switch 850. The PSTN interface 860 performs out-of-band signaling using Signaling System 7 (SS7) signaling protocol, such that the NE 800 can act as a central office (CO). The PSTN interface 860 coordinates with the NE central processor 830 to place and receive calls involving the PSTN. The NE interface 870 provides a fixed voice/data communication link for call routing to other NEs in the wireless network. The wireless communication system is configurable to support zero, one, or two external NEs. The NE interface supports three technology types: direct copper connections using DS-1 connections, direct fiber connections using OC-3 links, and radio links with the DS-1 bandwidth. The NE 800 includes a control bus 890 for routing data and control between the central processor 830 and the microcell servers 822, switch 850, NE interface 870, and PSTN interface 860. The control bus may be a 10/100 Mbps Ethernet LAN (local area network). An uninterruptible power supply (UPS) 880 is used to power the NE equipment and buffer it from the external power grid. In the event of an external power grid outage, the UPS battery backup capability is able to operate the NE for an extended period of time.

The nonvolatile read/write memory 916 is used for storing initialization parameters and phone book data so that battery removal or replacement does not require re-initialization. Each handset contains its phone number in non-volatile memory. The operational software is downloadable to change features or otherwise update the code. The operational software is stored in non-volatile memory 916. The operational software is downloadable using capabilities of the bootstrap software, an external data port, and external software. The handset is capable of maintaining user data in non-volatile memory 916, such as phone book entries. The handset includes a vocoder (voice coder/decoder) 944 for processing the digitized voice signals. The vocoder 944 compresses and channel code the digitized voice data in order to meet the voice quality requirement and to enable implementation of the RF and communication protocols. The ComDoc 900 includes a microphone 946 and speaker 948. The ComDoc 900 may accept an external microphone input signal and shall provide an external speaker output signal. The ComDoc 900 includes a power manager 930 to assist in extending battery life. The ComDoc 900 includes a rechargeable battery 934, but is also capable of connection to an external power source through an external power interface. The ComDoc 900 includes a secondary transceiver 950 to serve as a secondary or alternate mode to the wireless communication system described. The secondary transceiver implements one or more of the following standard wireless protocols:
PCS CDMA (IS-95)
PCS TDMA (IS-136)
GSM 1900
AMPS
The secondary transceiver 950 includes functions for an antenna, RF transceiver, protocol processing, and vocoder processing. The ComDoc 900 also includes provisions for a position locator function to support the enhanced 911 (E911) requirements if needed. The ComDoc 900 includes a PSTN line capture module 952 for connection to one or more PSTN lines. This enables multiple telephone jacks to be provided on the ComDoc 900 for connecting fixed telephone handsets 956 and computer modems to the PSTN lines 954. In addition to an audio annunciator 926 and a visual indicator 928, the ComDoc 900 provides handset recharge bays 932.

The ComDoc environmental package of integrity can be preserved when entering data via the induction coupling coil which is also used for the recharging of the internal batteries. The integrity of the environmental package can be maintained via the induction coil through the case of the environmental package without any external metal contact.
Turning now to FIG. 17, FIG. 17 shows examples of prefix codes 1700 that may be used to access ComDoc functions. To access a function 1710, one of these four-digit prefix codes 1720 must be entered prior to entering a handset access number, as explained in the description 1730. The access codes 1720 are meant to be examples of means for accessing available functions 1710 in the ComDoc through a handset keyboard.
