1. Technical Field
The present disclosed technology relates generally to antennas, and in particular to an electronic antenna identification module for telecommunications antennas.
2. Description of the Related Art
Telecommunications antennas that are compliant with the industry standardized Antenna Interface Standards Group (ASIG) protocol (specifications for the control and interface of antennas with digital remote control and monitoring capabilities) and the 3rd Generation Partnership Project (3GPP) (standard for global third generation (3G) mobile telephone system specifications) electronically communicate antenna information to network operators and enable remote control and monitoring through communications cables attached to the antennas. Such antennas consist of the antenna itself, and associated internal and external components. Current generation antennas are capable of communicating information about internal and external components such as: mechanical and electrical azimuth measurement and control; and the serial number, part number, version, firmware, production date, etc. associated with the respective internal and external components. However, current generation antennas are incapable of electronically communicating information about the antenna itself such as serial number, part number, version, firmware, production date, etc. What is needed is a AISG and 3GPP compliant antenna identification module capable of storing relevant antenna information for communication over the standardized AISG and 3GPP protocols.
Heretofore has not been available an antenna identification module with the advantages and features of the disclosed subject matter.
A telecommunications antenna identification module is provided for storing and transmitting antenna serial number, part number, version, firmware, production date, etc. to a network operator over AISG and 3 GPP compliant communications systems. The module consists of a printed circuit board mounting a programmable device capable of storing and transmitting programmed antenna information. The module is adapted for connecting to antenna communications cables using either AISG cable splitter or in-line in a daisy chain fashion. The device is programmed either in the field by a field technician or by the antenna manufacturer.

Referring to the drawings in more detail, the reference numeral 2 generally designates an antenna identification module embodying the principles of the disclosed subject matter. Referring to
The antenna 20 may contain internal electrical components, such as mechanical and electrical azimuth measurement and control, that have modules capable of transmitting the serial number, part number, version, firmware, production date, etc. associated with the respective internal components to a network operator through the communications cable 40 using the AISG or 3GPP protocol. Communications cables 27 providing date, application and signal transmission attach to the antenna 20 by mating the female AISG compliant connectors 24 of the cables 27 to the male AISG compliant connectors 22 of the antenna 20 and securing them together by tightening a threaded fastening nut 26.
In this embodiment, an AISG compliant device 28, such as a remote electrical tilt module, a remote control unit, or a tower mounted amplifier, is connected to the antenna 28 by mating a female AISG connector 30 of the device 28 to a male AISG connector 22 on the antenna 20, and securing them together by tightening a threaded fastening nut 32. The AISG cable splitter 10 allows the antenna identification module 2 to interface with the communications cable 40, and communicate with a network operator over the attached communications cable 40. The cable splitter 10 connects to the AISG compliant device 28 by mating a female AISG connector 12 on the splitter 10 with a male AISG connector 34 on the device 28, and securing them together by tightening a threaded fastening nut 14. In turn, the communications cable 40 is connected to the AISG cable splitter 10 by mating a female AISG connector 36 on the cable 40 with a male AISG connector 16 on the splitter 10, and securing them together by tightening a threaded fastening nut 38.
An antenna identification module 52 comprising another embodiment or aspect of the disclosed subject matter is shown in
The module 52 is connected to communications cables 40 in-line in a daisy chain fashion by securing the female AISG connector 36 to the threaded male AISG input connector 54, and securing them together by tightening the threaded fastening nut 3. The female AISG output connector 56 is connected to a male AISG connector 60 attached to an end of a communications cable 40, and they are secured together by tightening the threaded fastening nut 58. In this embodiment, the cables 40 may connect to the antenna, or an AISG compliant device. As described above, antenna information can be programmed into the module 52 in the field by a field technician, or by the antenna manufacture.
An antenna identification system 102 comprising yet another embodiment or aspect of the present invention is shown in
The alternative embodiment sensor system 102 is a solution for cellular network carriers which utilize multi-band antennas operating on one or more frequency bands. It is important for the network provider or carrier to know the mechanical tilt and roll of all directional antennas in the network. This is made complicated by multi-band antennas with multiple remote control units (RCUs). The multi-band antenna may have one more RCUs for every frequency band in use.
Each RCU can be controlled by one or more primary controllers (CCU). Such CCU controllers may be installed as a module inside a BTS station, but must also be part of the BTS or antenna transceiver. Identification data can be accessed by either running control cables up the mast or other structure a multi-band antenna is mounted to, or by combining the control signals with the transmitted radio signals over an antenna feeder cable. In this way, the data flow stems from the individual CCU, thus forming separate systems.
The antenna identification module 104 provides multiple individual communication ports 105 for multiple communication protocols. The antenna identification module 104 shares its detected information over the multiple communication ports 105. The antenna identification module 104 feeds into a master micro controller 106, which in turn communications with an unlimited number of slave micro controllers 108, at least one for each communication protocol. These slave controllers 108.1, 108.2, 108.n in turn control the slave communications modules 110.1, 110.2, 110.n, power supplies 112.1, 112.2, 112.n, and other components located in each protocol. Because each protocol contains a separate power supply 112, each protocol will respond as an individual device.
The antenna identification module 104, as described in the previous embodiments, may be a one, two, or three axis accelerometer. The module 104 can communicate its readings across the communication ports 105 to the master controller 106, which then handles each of the unlimited number of slave protocol systems. This allows a single antenna identification module 104 to capably monitor and report on a multi-band antenna no matter the number of protocols used by that antenna or the number of independent antenna motors or busses are included in the multi-band antenna.
It will be appreciated that the components of the antenna identification system assemblies 2, 52, and 102 are AISG and 3rd Generation Partnership Project (3GPP) compliant, and can be used for various other applications. Moreover, the sensor assemblies 2, and 52 can be fabricated in various sizes and from a wide range of suitable materials, using various manufacturing and fabrication techniques.
