Problems solved by technology

However, if a new tower-mounted amplifier TMA is added, or if an existing TMA is replaced, then parameter data relating to the added / replaced TMA must be inconveniently manually entered into the remainder 13 of the fixed site transceiver, which cost money and time

Embodiment Construction

[0019] Figure 2 schematically shows the relevant parts of an exemplary base transceiver station according to the invention, the base transceiver receiver of Figure 2, which may be used, for example, in a GSM network, comprising a tower mounted amplifier (TMA) 23 and A remainder of 25. The tower mount amplifier section 23 of FIG. 2 includes a supply current modulator 22 coupled between the bias tee module 19 and the local power supply 16 . Modulator 22 utilizes the TMA parameter data to modulate the supply current drawn by tower mounted amplifier section 23 from TMA power supply 17 (via RF feed line 15).

[0020] The supply current drawn from the TMA power supply 17 is monitored by an A / D converter 21 coupled to the TMA power supply output 24, and the digital output of the A / D converter is input to a data processor 27 coupled to the A / D converter, the data Processor 27 interprets the digital data received from the A / D converter to recover TMA parameter data modulated by modula...

Abstract

In a fixed-site radio transceiver station, information about a tower-mounted radio frequency amplifier apparatus can be automatically transferred from the tower-mounted radio frequency amplifier apparatus to another portion of the fixed-site radio transceiver station. The information is transferred by modulating a power supply current that is drawn from the other portion by the tower-mounted radio frequency amplifier apparatus.

Description

technical field [0001] The present invention relates generally to fixed-site radio transceiver stations, and more particularly to data transfer in fixed-site radio transceiver stations. Background technique [0002] In a typical fixed-location radio transceiver station (also known as a base transceiver station or base station) used in a wireless communication network, the radio antenna and associated amplifier are typically mounted on top of a tower structure, And through the radio frequency (RF) feeder cable connected to the rest of the base transceiver receiver (remainder). The RF feeder cable is also typically used to supply DC supply current to a tower mounted amplifier (TMA). [0003] FIG. 1 is a block diagram of an example of the above-mentioned conventional base transceiver station, for example, a base transceiver station used in a conventional GSM (Global System for Mobile Communications) wireless communication network. The example of FIG. 1 shows a tower mounted a...
