Base station system, tower top amplifier, base station and feeder line length measuring method

Abstract

A base station system comprises base station, feed line, tower-top amplifier and antenna, switch for switching on-off up-link signal input end to down-link signal output end of feed line, current measurement unit for measuring current value of loop formed by said base station and said feed line, voltage measurement unit for measuring voltage value between up-link signal input end and down-link signal output end in said loop.

Description

Base station system, tower mount amplifier, base station and feeder length measurement method technical field The invention relates to wireless communication technology, in particular to a base station system, a tower top amplifier, a base station and a feeder length measurement method. Background technique With the development of mobile communication technology, at present, the mobile communication network has transitioned from the 2G era to the 3G era, and continues to develop. Wireless signal coverage is a basic requirement for providing mobile communication services, which requires a base station system for providing wireless signal coverage, which includes a base station, a feeder cable, and an antenna. As shown in Figure 1, it is a schematic structural diagram of a base station system in the prior art. In this base station system, after the wireless signal is output from the base station, it is transmitted through a feeder line or a feeder cable composed of multiple ...
