     BACKGROUND 
       [0002]    Currently many wireless operators use RET (remote electrical tilt) antennas. RET antennas allow wireless operators to remotely control the beam attributes, including, for example, beam direction, of one or more antennas. 
         [0003]    Typically, the RET antenna beam attributes are adjusted using motors or actuators according to specifications promulgated by the Antenna Interface Standards Group (AISG). Relevant specifications may be found at http://www.aisg.org.uk (incorporated by reference). While the use of RET antennas has proved advantageous, the setup of such antennas currently requires considerable effort. In order to setup, troubleshoot, and control RET antennas, several different portable controllers may be required. For example, when trouble-shooting RET antenna configurations, crews currently depend on separate electrical measurement and troubleshooting devices which are difficult to use. Additionally crews are often overwhelmed and do not know how to trouble-shoot RET configurations. 
         [0004]    When technician crews are on site, wireless operators require the technician crews to provide “close-out-packages” to the wireless operators as a proof of work. A close out package is a key deliverable. Especially during a new installation, preparation of a close out package involves a substantial amount of effort. Currently, technician crews must capture screenshots of controller windows (sometimes with using a camera), manually export selected data, and manually measure and record the location of the antenna with a GPS receiver. Often, the disparate sources of information are manually collected and written to a CD ROM or DVD ROM. Photographs of display screens may be saved in directories on the disks. 
         [0005]    The initial azimuth direction of an antenna is often a requirement of the wireless operator, and may depend on topography and the location of physical obstructions. In one known method of alignment, a technician may aim the antenna with the aid of a magnetic compass. However, the antennas being aimed, and the structures on which they are mounted, may introduce significant magnetic deviation to the compass, which adversely affects the accuracy of the installation. In an alternative known method, technician crews depend on complex and expensive alignment devices to align each antenna so that the main beam direction points to the desired azimuth direction. In one example, an alignment tool includes two GPS antennas on arms sufficiently long so that a GPS receiver can detect the location of each arm and thereby determine an azimuth angle for the alignment tool. A disadvantage of such a tool is that arms sufficiently long to make the tool effective are also sufficiently long to make the tool cumbersome and difficult to use on a cell phone antenna tower. 
       SUMMARY 
       [0006]    A Master Antenna Controller is provided herein. In one example, the Master Antenna Controller comprises a RET Master which may replace several devices, provide full RET control based on the AISG 1.1 and 2.0 standards, provide extensive, screen-guided, intuitive RET diagnostics functionality, and provide an alignment tool free from the problems of magnetic deviation and cumbersome differential GPS antennae. The RET diagnostics functionality may include measurements of voltage, current, and AISG protocol commands. The RET Master may also include multiple different pre-defined tests (e.g. test one actuator, test one RET cable, test AISG signal from TMA) and also some standard electrical tests, e.g. measuring voltage, current etc. Users will be guided on the screen about how to test and what steps to do and the software will guide the user through several steps for an easy and quick trouble-shooting process. 
         [0007]    The RET Master may include a Close-Out-Package Wizard, which will allow technician crews to create standardized close out packages with a few clicks. The Close-Out Package Wizard significantly reduces the time required of the technicians to prepare the close out packages. Also, the wizard provides a standardized close out package format to ensure that the same format is used by all technician crews. 
         [0008]    The RET Master may be hand-held and battery powered which will allow using that unit on a tower. The RET Master may have a touch-screen for easy handling on site. The RET Master may also have a GPS receiver for easy location measurements. These location measurements may be included in the close out packages. Also, the GPS functionality and different user locations may be employed by the RET Master to perform the functions of an alignment tool for antenna azimuth direction.

     DETAILED DESCRIPTION 
       [0021]    A RET Master  10  according to one example, is a hand held AISG-compliant controller. The RET Master  10  enables a technician to perform initial setup testing, installation configuration, and trouble shooting diagnostics of all Antenna Line Devices, Remote Electrical Tilt Devices, and Tower Mounted Amplifier. The RET Master  10  is preferably small in size and operable from a battery or a wall plug-in power supply. In one example, the RET Master  10  has a processor and supporting hardware sufficient to operate the Windows CE operating system. Other operating systems suitable for handheld or portable devices may also be used. The RET Master  10  includes enough non-volatile memory storage to hold the operating system footprint, antenna configuration files, AISG protocol stack, and preferably room for future growth. 
         [0022]    Exterior views of one example for RET Master  10  are provided in  FIGS. 1 and 2 . The RET Master  10  of this example has a graphical display  12 . In one example, the graphical display  12  may further comprise a touch screen for input. The RET Master has a power connector  14  for receiving DC power from an external power source, such as an A/C wall power supply and charger (not shown), a USB connector  16  and a memory card connector  18 . The memory card connector may be for a Secure Digital (SD) card. The connectors may be protected by a cover  20 . Grips  22  may be provided for ease of holding the RET Master  10  in use. Male AISG connector  24  and female AISG connector  26  are provided. 
         [0023]    A RET Master  10  may include various hardware blocks.  FIG. 3  illustrates one example of how hardware may be arranged in a RET Master  10 . In this example, the main processor subsystem  30  is connected to a display/touch screen subsystem  32 , a power management/battery charger subsystem  34  and an on/off switch  36 . The main processor subsystem  30  may be implemented on a circuit board as a complete system on a module capable of driving the graphical display  12 , accepting input from the touch screen, of the graphical display  12  communicating to any AISG 1.0 and 2.0 devices and having the hardware ability to do diagnostic testing on the AISG interface. Block diagrams of examples of main processor boards are provided in  FIGS. 4-7 . 
         [0024]    The power management/battery charger subsystem  34  may further be connected to a battery pack  38 . Any suitable battery pack may be used. In one example, the battery pack  38  may further comprise a NiMH smart battery pack with fuel gauge, sub-system. Preferably, the battery pack will incorporate a thermal fuse and a current fuse for protection. 
         [0025]    In an alternate embodiment, hardware blocks may include a digital camera and a GPS (Global Positioning System) receiver. 
         [0026]    One example of a main processor subsystem  30  is illustrated in  FIG. 4 . The main processor subsystem  30  of this example includes a processor  50 , a storage memory  52 , working memory  54 , AISG diagnostics logic  56 , GPS module  58 , AISG connector  60 , display and keyboard connector  62 , power input connector  64 , voltage and power management  66 , and a USB interface and connector  68 . 
         [0027]    The processor  50  preferably includes multimedia capabilities. In one example, the processor is based around an ARM11 core and operates at about 500 MHz. In this example, the system implemented by the processor includes multimedia and floating-point hardware acceleration, a floating point co-processor, advanced power management, and security. 
         [0028]    The storage memory  52  is coupled to the processor  50  and preferably comprises NAND Flash memory. The NAND Flash memory may include a high density  2 G-bits, low power, 1.8 Volt memory. This storage memory  52  may be used to store the operating system. Additionally, the storage memory  52  may be used to store antenna configuration files and firmware upgrades for tower top RET, TMA and CAD devices. The processor  50  may acquire previously stored antenna configuration information from the storage memory  52  as may be needed. 
         [0029]    The working memory  54  is coupled to the processor  50  and may comprise RAM memory. In one example, the main board includes 1 Gig-bit of double data rate, low power, 1.8 Volt, 133 MHz, volatile random access memory. This DDR memory is arranged in a 32 Meg×32 bits wide (8 Meg×32-bit×4 banks). 
         [0030]    USB interface and connector  68  may comprise a Universal Serial Bus interface transceiver (PHY) that is USB 2.0 On-The-Go compliant. The connector on the board may be the Mini USB connector. The USB interface and connector  68  is coupled to the processor  50 . In an alternative example, a USB interface may be integrated into the processor  50 . 
         [0031]    The main processor subsystem  30  may include GPS module  58 . The GPS module  58  is coupled to the processor  50  and may be used, for example, to determine cell tower locations and assist in antenna alignment. The location information may be used for documentation proposes and to help with diagnostics documentation. In one example, a suitable GPS module  58  is a 20 Channel Global Position System receiver surface mount device. Modules which have fast acquisition times, high receiver sensitivity and low power consumption in a small, compact form factor are preferred. In one example, the RET Master  10  includes a passive antenna for GPS signal reception. Alternatively, an active antenna may be used. The Main processor subsystem  30  may include provisions for assembly with either a passive or active GPS antenna. 
         [0032]    In one example, voltage and power management  66  may comprise an integrated power management IC for applications which require multiple power rails. The power management IC may provide three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O, and memory voltage rails in a processor based system. In the RET Master  10  the power management IC provides 1.45V, 1.8V, and the 2.5V voltages to run the main processor subsystem  30 . This power management IC manages the low power modes of the processor. The low power modes include Run, Wait, Doze, Retention state, Deep Sleep, and Hibernate modes. 
         [0033]    AISG Connector  60  on the main processor subsystem  30 . This AISG-compliant interface preferably includes two standard 8-pin, AISG Connectors, male AISG Connector  24  and female AISG Connector  26 . The female AISG connector  26  may also be used to output the RS-485 interface from the hand held controller per the AISG 1.0 and 2.0 protocol and 24 volts to power a RET/TMA device. The male AISG connector  24  may be used for electrical diagnostics at the physical layer. The male AISG connector  24  interface may be used to check an AISG cable for opens, shorts, and to check to see if there is continuity on the RS-485 signal. 
         [0034]    MSG diagnostics logic  56  is provided to help a service technician diagnose problems with any module hooked up to the AISG connector. The AISG logic  56  is coupled to the AISG connector  60  and to the processor  50 . This circuitry will monitor the voltage and current (power) of the 24 volt supply from the female AISG connector  26 . It will also monitor for a short circuit condition on the RS-485 interface. The RET Master  10  may also be configured to reset a RET device by turning off/on the power without needing to physically remove the connector. 
         [0035]    The main processor subsystem includes several connectors. Display and keyboard connector  62  is coupled to the processor  50  and includes, for example, three separate connectors; one for a display, one for a touch screen, and one for a keyboard. Other provided connectors include power input connector  64  and a diagnostic port  72 . The diagnostic port  72  may be used for debug purposes used by engineering. The diagnostic port  72  includes RS-232, RS-485, reset, voltages and other nets used for debugging the main processor subsystem  30 . Additionally, a JTAG test connector used for software debugging may be provided. Male AISG connector  24  and a female AISG Connector  26  may also be on the main board. 
         [0036]    The display/touch screen subsystem  32  may include any suitable graphical display  12 . In one example, the graphical display  12  is approximately five inches diagonal with an 800×480 pixel resolution and has a 24-bit RGB interface. The graphical display  12  preferably comprised a touch-sensitive display. 
         [0037]    In an alternate embodiment, illustrated in  FIG. 5 , the processor  50 , storage memory  52 , working memory  54 , AISG diagnostics logic  56 , GPS module  58 , AISG Connector  60 , Display and Keyboard connector  62 , power input connector  64 , voltage and power management  66  are largely the same as the embodiment of  FIG. 4 , and the descriptions of such are incorporated by reference. This alternate embodiment and a USB interface and SD card connector  68   a , which combines the interface functions of the USB and memory card connectors. The USB interface and connector  68  of  FIG. 4  may be modified to include memory card support. Also, the embodiment of  FIG. 5  includes a camera board connector  70 . An integrated camera is an optional feature of the RET Master  10 . 
         [0038]    Another alternate embodiment of main processor subsystem  30  is illustrated in  FIG. 6 . This example includes features of the power management subsystem  34 . The processor  50 , storage memory  52 , working memory  54 , AISG diagnostics logic  56 , GPS module  58 , AISG Connector  60 , Display and Keyboard connector  62 , are largely the same as the embodiment of  FIG. 4 , and the descriptions of such are incorporated by reference. This example further includes RS-232 port  72  for the purpose of debugging and testing. This port will go to a connector that will be used for engineering. Typically, this port would not be used by the technicians in the field. This example also illustrates additional features of power management, including a 24 Volt input from an AC to DC wall power supply  74 , a battery charge controller  76  coupled to the 24VDC input from wall power supply  74 , a battery pack  78 , a step up converter  80 , and a diode  82 . The AISG interface may also be powered directly by the 24VDC input, if the RET Master  10  is plugged into the wall charger when in use. Also shown is a step down voltage converter  84  to step the voltage down from the battery voltage (or wall charger voltage) to 5 VDC. Also shown is a step down converter  86  to step down from 5 VDC to 3.3 VDC, and a DC to DC converter  88 , which provides output voltages of 1.3 V, 1.8 V, 2.5 V and 2.8 V from a 5 V input. 
         [0039]    The battery charge controller  76  may be coupled to the 24VDC input. The step up converter  80  may convert the battery voltage to voltage suitable for the AISG interface. 
         [0040]    Referring to  FIGS. 6 and 7 , an example of the power management subsystem  34  is provided. The power management subsystem  34  provides an interface between the battery pack  38 , the wall power supply (not shown), and the main processor subsystem  30 . The power management board accepts, in one example, 24 volts input from a wall power supply. The main functions of the Power Management, Battery Charger board include: accepting input for a wall type power supply for the purposes of charging the battery pack while the unit is in operation; battery pack charging; establishing a communications path from the smart battery pack&#39;s fuel gauge to the main processor board, and distributing three voltages to the main processor subsystem 30, 24 Volts, 5.0 Volts, and 3.3 Volts. 
         [0041]    The battery pack  38  supplies power to the RET Master  10  circuitry, and preferably includes a thermal fuse, and a current limiting fuse. The battery pack  38  may be packaged in a shrink wrap enclosure with wire leads and a connector for plugging into the power management/battery charger subsystem  34 . Preferably, the battery pack  38  supports a load of 24 watts for 5 minutes, and 5 watts for 115 minutes, without needing to be charged. In one example, the battery pack  38  comprises 8 NiMH cells producing a 9.6 volt output. 4/3A cells may be used. Preferably, the battery pack  38  would provide a run time of approximately two hours. The 8 NiMH cells may be shrink wrapped together, with a connector for voltage, ground, and battery temperature. 
         [0042]    The wall power supply may be any suitable supply. In one example, the wall type power supply is an off the shelf, 60 watt, 24 volts DC out power supply. 
         [0043]    The RET Master  10  is configured through hardware and software to include the following features\functionality: 
         [0044]    AISG line device communication, configuration, scanning, programming and upgrading. 
         [0045]    Simple yet intuitive UI to help user navigate between the various features. 
         [0046]    History workflow for task at the site (includes image acquisition and storage). 
         [0047]    Diagnostic for monitoring voltage and current reading on the AISG line. 
         [0048]    Ability to power off the AISG line without disconnecting the AISG connection. 
         [0049]    In one example, an appropriate software architecture may include a layer design approach. A layer design approach will provide decoupling between the various library components as well as hide and abstract details of a component for the calling application. An example of this is shown in the rendering interface driver that can support OpenGL or DirectX. To ensure robustness and flexibility for the software to change based on priorities and requirements, each layer component may provide a clear set of APIs that require minimal changes to existing interface but provide the ability to add new interfaces if necessary. 
         [0050]    In one example, the software for the RET Master  10  includes the following software dependencies: 
         [0051]    BSP clone of iMX31. 
         [0052]    Display device drivers supporting resolution of 800×480×24. 
         [0053]    Camera drivers supporting camera configuration and programming. 
         [0054]    Touchscreen driver supporting i2c communication. 
         [0055]    Serial drivers supporting RS-232. 
         [0056]    Generic WinCE USB drivers. 
         [0057]    MFC runtime dlls. 
         [0058]    OpenGL ES dlls. 
         [0059]    Generally, a RET Master application  110  includes certain system components. These system components may include a Core Runtime Library, an AISG stack framework, a Camera Library, a GPS Library a Geometry Renderer, an Open GL Renderer and an Application Layer. 
         [0060]    The Core Runtime library comprises an underlying library module having a set of API classes supporting Unicode, logging, memory tracking and diagnostic, memory management, etc. 
         [0061]    The AISG Stack framework includes Layer 2 and Layer 7 classes providing the AISG protocol for AISG line devices. This library also provides a workflow for AISG messaging. 
         [0062]    The Camera Communications Library is a library component that communicates with an image sensor, such as an Aptina image sensor. It exposes public classes that expose the hard independent functionality to a calling application. As noted above, the camera function is optional. 
         [0063]    The GPS Communications Library is a library component that communicates with the GPS receiver through serial I/O. This component will expose a set of class APIs that is independent of the GPS receiver. Internally, it will use the standard NMEA (such as NMEA 0183) to gather GPS communication. The processor may acquire location information from the GPS through this interface. 
         [0064]    The Geometry Renderer is a rendering engine that provides material system, object entity hierarchy, scene graph rendering, interface into directx\opengl rendering API. The OpenGL Renderer is a driver layer interface provides communication between the GPU and the calling application. In one example, the iMX31 integrated GPU provides the OpenGL ES 1.1 hardware acceleration driver. This particular version limits the use of assembly or HLSL shaders but provides the TnL hardware support. 
         [0065]    In one example, top-level view of the various components and entities that make up the RET Master application  110  is shown in  FIG. 8 . The Application Driver Layer  112  includes UI Presentation  114 , Power Management  116 , Data Storage  118 , and Device Configurations  120 . The Application Interface Layer  122  includes a Rendering Module  124 , Rendering Device  126 , AISG Stack  128 , GPS Module  130 , OpenGL ES Renderer  132 , GPS NMEA Comm  134 , and I/O Driver  136 . Optionally, as shown, the Application Interface Layer  122  further includes may also include a Camera Module  138  and Camera Communication module  140 . The OS Kernel  142  may include a Bootloader  144 , Touchscreen Driver  146 , Display Driver  148 , GPU Driver  150 , Block Driver  152 , and Stream Driver  154 . 
         [0066]    In another example, illustrated in  FIG. 9 , an RET Master application  210  includes the following Application Layer  212  components: UI Presentation  214 , Data Storage  218 , Windows Viewport  260 , Diagnostics  262 , App Configuration  264 , and System Configuration  266 . Additional system libraries include MFC  268  and Stream I/O  254 . In this example, the application interface layer may include the AISG Stack Framework  228 , NMEA Stack  234 , Camera  238 , Rendering Driver  226 , and OpenGL ES  232 . These entities interact with the Core Runtime environment (e.g., the OS Kernel layer  142 ). 
         [0067]    The RET Master Application Layer includes a User Interface (“UI”) system that will allow the user to navigate between the various components. For example,  FIG. 10  illustrates one example of a “main menu” screen shot  300  of the display  12 . The main menu provides virtual buttons for selecting activities. The buttons include Devices  302 , Con figure 304 , Diagnose  306  and Miscellaneous  308 . Also included are buttons for help (“?”)  310  and Back  312 . An image area  314  may be used to display an image, such as a photograph of the installation being serviced. 
         [0068]      FIG. 11  illustrates one example of a scan process screen  320 . Scan process screen  320  includes virtual buttons for Scan  322 , Actuator  324 , TMA  326 , and Smartbeam  328 . The scan process screen  320  also includes a Cancel Scan  330  button and a scan progress bar  332 . The processor  50  acquires information from devices found during the scan. Information window  334  displays information regarding the devices found during the scan. 
         [0069]    The application is also responsible for loading the interface drivers for the camera, GPS, renderer, AISG stack, etc. RET Master  10  is the main entry point for the user and, in one example, is the only application accessible by a field technician on the device. The file system, utilities and system applications are not typically directly accessible. 
         [0070]    In use, one function of the RET Master  10  is to serve as a controller for RET antennas. Typically, the RET Master  10  is connected to a bus via the AISG connectors  24  and/or  26 . The RET Master Application  110  presents graphical representations of antenna control commands via the user interface and receives selected commands in the user interface. In one example, as illustrated in  FIG. 11 , the RET Master  10  is configured to display a screen from which a user may select a “scan” button. The RET Master  10  application starts a scan process and opens scan communication onto the bus. When an actuator is found, additional information is queried on the device. The RET Master  10  registers the device onto its device list and propagates the information to the UI thread. The User Interface system updates the device UI list with the newly added device. As illustrated in  FIG. 11 , the information may be displayed in information window  334 . The scan process may periodically update itself. 
         [0071]    The RET Master  10  may also be configured to control non-AISG actuators. In this example, a user selects a non-configured actuator. The user selects on the button “Edit Selected” which will bring up the “Edit Selected” dialog for the actuator. The user may then select an antenna model from an Antenna Model selection menu. The user selects a “Commit” button. RET Master application  110  looks up the information for the selected antenna model and configures the selected actuator. The RET Master application  110  then updates the “model” UI element with the configure antenna model for the actuator. 
         [0072]    To activate a tilt actuator, in one example, from the device screen, the user selects the actuator to tilt. The user clicks on the “Move Selected” button. The RET Master application  110  launches the “Move Selected” form. The user provides a tilt value in the tilt UI element. The user clicks on the “Commit” button. The RET Master application  110  disables all UI-enabled elements on the “Move Selected” form. The RET Master application  110  sends the command to tilt the actuator. The RET Master application  110  updates the current tilt value for the actuator. The Ret Master application  110  enables the UI-enabled elements on the “Move Selected” form. Other movements of the RET antenna (e.g., Pan) may be controlled in a similar manner. 
         [0073]    The RET Master  10  may also be used according to alignment process  350 , illustrated in  FIG. 12 . A first technician may record a location of a cellular antenna tower (step  352 ) using the GPS functionality of the RET Master  10 . Through inputs made via the touch screen or other input means on the RET Master  10 , the technician may then indicate which of the antennas on the tower requires alignment (step  354 ). The RET Master  10  then determines the desired azimuth angle (step  356 ) for the selected antenna from information provided by the wireless operator. Alternatively, the step of determining the described azimuth angle (step  356 ) may be performed by the technician who may then enter a desired azimuth angle. The RET Master  10  then provides alignment information. The RET master  10  determines a location for the technician to position him or herself to serve as an alignment point (step  358 ). The alignment point is chosen such that, when the selected antenna is aimed at the alignment point, the desired azimuth angle is achieved. The RET Master  10  then guides the technician to the alignment point (step  360 ). In one example, the RET Master  10  may display a heading to walk (graphically, with an arrow if so desired) and a distance to walk from the tower base. The RET Master  10  receives updated location information from the GPS as the technician moves toward the alignment point. In one example, when the first technician holding the RET Master  10  has reached the alignment point, the RET Master  10  indicates to the first technician to stop. In the final step, a second technician on the tower may align the antenna by pointing the antenna at the first technician standing at the alignment point (step  362 ). This technique avoids the known disadvantages of tower-induced magnetic compass deviation and hauling cumbersome, expensive alignment tools aloft. 
         [0074]    The RET Master may include a Close-Out-Package Wizard, which will allow technician crews to create standardized close out packages with a few clicks. The close-out package is a predefined report documenting that the antennas in an associated cell tower are installed and operating according to the requirements of a wireless operator. The Close-Out Package Wizard significantly reduces the time required of the technicians to prepare the close out packages. Also, the wizard provides a standardized close out package format to ensure that the same format is used by all technician crews.
