Abstract

The present application relates to a communication device and a repeater. The communication device comprises a radio frequency transceiver module, a splitter / combiner, a frequency conversion module, adigital module and a microwave transceiver module which are connected in turn. The microwave transceiver module comprises a microwave transceiver unit, a microwave demultiplexer and a microwave antenna, wherein the microwave transceiver unit comprises a master microwave transceiver unit and a slave microwave transceiver unit; The radio frequency transceiver module transmits the radio frequency signal received from the communication side to the demultiplexer, so that mast radio frequency signal and the slave radio frequency signal are formed, The master frame signal and the slave frame signalare respectively transmit to a frequency conversion module, after the frequency conversion module converts the master intermediate frequency signal and the slave intermediate frequency signal, the master frame signal and the slave frame signal are respectively transmitted to a digital module for frame processing, and master frame signal and slave frame signal are obtained.A main microwave transceiver unit and a slave microwave transceiver unit transmit that master frame signal and the slave frame signal from a microwave antenna through the splitter / combiner. The communication device can realize the module-level switching backup of the microwave transceiver unit of the near-end unit or the far-end unit of the repeater.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a communication device and a repeater. Background technique [0002] In recent years, repeaters have been promoted and applied on a large scale in the field of mobile communications by virtue of their strong networking capabilities, wide coverage, low noise, low power consumption, convenient debugging, and low failure rate. Explosive demand for Internet and broadband data services. [0003] Among them, the near-end unit and the far-end unit of the repeater can transmit data through optical fiber, and can also transmit data through microwave. However, in the actual environment, the burial of optical fibers may require many prerequisites, so repeaters that use microwaves to transmit data have a wider application environment. [0004] However, for the above-mentioned repeater that transmits data through microwaves, if the microwave transceiver unit is abnormal, the...
