Embodiment 3

[0048] The repeater disclosed in the third embodiment can change the real-time intermodulation detection of a single point into the real-time intermodulation detection of the whole network, which is beneficial to the operator's management and later maintenance.

[0049] Embodiment 4 of the present invention discloses a working process of a repeater, see Figure 4 It is a flow chart, and the working process includes:

[0050] Step S101: The processor receives preset base station downlink frequency point information input through the MT port of the repeater, and determines an intermodulation detection frequency point corresponding to the downlink frequency point information;

[0051] Wherein, the preset downlink frequency point signal of the base station may be manually input by an engineer or remotely configured by a network administrator, but the input is all downlink frequency point information of the base station.

[0052] Step S102: Send the intermodulation detection frequ...

Abstract

The invention discloses a repeater comprising a repeater MT port, a standing wave detector, a receiver and a processor. The standing wave detector enables upstream signals to be coupled and sends the upstream signals to the receiver, then power of the upstream signals can be sampled, downstream frequency point information is transmitted to the processor through the repeater MT port, the processor determines an intermodulation detection frequency point corresponding to a downstream frequency point according to the downstream frequency point information, and the processor can control the receiver to detect a power value of the intermodulation detection frequency point. The repeater can detect intermodulation interference signals.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201210201585.4 and the title of the invention "a repeater" submitted to the China Patent Office on June 18, 2012, the entire content of which is incorporated in this application by reference. technical field [0002] The invention relates to the field of wireless communication, in particular to a repeater. Background technique [0003] In the wireless communication system, the repeater is a two-way active amplification device deployed between the base station and the mobile phone to improve the coverage quality of the antenna, and it is a simple two-way amplifier. The MT port in the traditional repeater Connect the coverage antenna through the antenna feeder network to complete the user coverage. [0004] In the existing mobile communication network, especially in the GSM wireless communication system, a large number of repeater devices are deployed. The existing repeate...
