Problems solved by technology

Although providing a satisfactory solution, this method is limited in application because the applied signals conveying operation and maintenance information may adversely affect certain antenna near-component components, or the interference is related to the near-component of the antenna Execution of a management function (e.g. management of tower-mounted amplifiers) of

no. 1 example

[0011] For the first embodiment, a transmitter and receiver are connected to a remote antenna using a radio frequency feeder supporting multiple communication channels. Install the antenna near part next to this far antenna. The transceiver is connected to the antenna near part assembly. Using a supported communication channel, establish a communication link between the transceiver and the transmitter and receiver, including the operation and maintenance communication link, through the antenna near component assembly and on the radio frequency feedline connected to the antenna.

[0012] For the second embodiment, the transmitter and receiver are connected to the remote antenna using a radio frequency feeder supporting multiple communication channels. Install the antenna near part next to this far antenna. The transceiver is connected to the antenna near part assembly. Establish a communication link between the transceiver and the transmitter and receiver, including the operation and maintenance communication link, using a supported communication channel over the air interface connection to the remote antenna and the RF feeder connected to the antenna .

[0013] In an implementation of the invention involving a cellular telephone system, a mobile station transceiver is connected to an antenna near component assembly at a cell site. A communication connection is then established between the transmitter and receiver of the cellular base station and the mobile station transceiver using the control or traffic channel of the cellular telephone system. Ope...

Abstract

An operation and maintenance communications link (40) is established between an antenna near parts component (18) and transmitter and receiver of a transceiver site assembly. The transmitter and receiver are connected to a remote antenna (14) by means of a radio frequency feeder (16) supporting a plurality of communications channels. A radio transceiver (42) is connected to the antenna near parts component. A communications connection comprising the operation and maintenance communications link (40 (1)) is established between the radio frequency transceiver and the transmitter and receiver over the radio frequency feeder connected to the antenna using a selected one of the supported communications channels. Another implementation further utilizes an air interface connection (40 (2)) supporting the selected communications channel to provide the operation and maintenance communications link.

Description

Background of the invention [0001] invention technical field [0002] The present invention relates to an antenna device and in particular to an operation and maintenance interface for the antenna device. [0003] Description of prior art [0004] In some antenna installations, Antenna Near Parts (ANP), such as tower-mounted amplifiers and active antennas with arrays of power amplifier modules, are used with radio transmitter (TX) and receiver (RX) arrangements. Some parameters related to near-component operation of the antenna, such as gain, are configurable. The operation of the near part of the antenna can also be controlled by software, so there may be situations where a software upgrade needs to be downloaded to the near part of the antenna to correct a program error or to provide additional functionality. Antenna near components may also have inherent testing and management functions that need to be performed on a regular basis. Furthermore, radio transmitter and rec...
