Abstract

This invention discloses a third generation mobile communication repeater system compatible in multi-system including orderly connected input signals, input unit, a system unit, an output unit and an antenna, in which, a primary monitor unit, a modem and the input unit are connected orderly, a switch supply supplies to the primary control unit, the modem and the system unit, which can be a TDSCDMA16 unit, a WCDMA unit or a CDMA 2000 unit, or any two kinds of them.

Description

technical field [0001] The invention relates to a mobile communication repeater system, in particular to a third-generation mobile communication (abbreviated as 3G) repeater system compatible with multiple standards. Background technique [0002] Mobile communication repeater (Repeater, also known as mobile communication same-frequency repeater) is widely used in blind and weak areas where base station signals are difficult to cover, such as shopping malls, hotels, Airports, docks, stations, gymnasiums, entertainment halls, subways, tunnels, expressways, sparsely populated mountainous areas, islands and other places play an extremely important role in solving network coverage, optimizing network structure, and improving network quality. Therefore, in the current 2G ~ 2.5G mobile network, the repeater has always been a preferred solution to improve the extended coverage of the wireless communication network. Also in the 3G era, the repeater will still be a preferred solution...
