Problems solved by technology

The main disadvantages brought about by this are: it cannot meet the bandwidth requirements of different operators, and the flexibility is poor, so the bandwidth needs to be continuously adjustable to change the bandwidth of the repeater
[0008] The above-mentioned measures can realize the adjustment of multiple specific bandwidths, but the cost of implementation is relatively high in actual engineering, and the bandwidth cannot be continuously adjusted

Abstract

This invention relates to a play over station with adjustable bandwidth including: a pair of signal output / input modules a pair of duplexes, an up link, a down link and a monitor unit, among which, the up and down links are serial between said duplexers, said signal output / input modules are serially connected with the duplexers separately, the links contain a low noise simplifier and a power amplifier serial to each other, said monitor unit is serially connected with the two amplifiers, characterizing that a bandwidth regulation module is serial between the two amplifiers and serially connected with the monitor unit to adjust the bandwidth of the play over station by the way of lamination after offset.

Description

【Technical field】 [0001] The invention relates to a coverage system of mobile communication signals, in particular to a repeater. 【Background technique】 [0002] With the promotion and popularization of mobile communication networks such as GSM and CDMA, it is fast, economical and effective to improve and optimize the network signal coverage quality by using different types of repeaters. Therefore, it is extremely important to install and use repeaters. means of network optimization. Compared with the base station, it has the advantages of simple structure, less investment and convenient installation. It can be widely used in blind and weak areas covered by mobile communication signals, such as shopping malls, hotels, airports, tunnels and other places, to improve communication quality and solve the problem. Call drop and other issues. [0003] Mobile communication repeaters can generally be divided into frequency-shifting repeaters, frequency-selective repeaters, optical ...
