Problems solved by technology

When a user who is close to the service antenna makes a call, the receiving power of the service antenna is large, and the uplink will experience gain compression; at this time, if a user at the edge of the service antenna makes a call, the call may not be able to go online. Users in may experience dropped calls

Abstract

The invention discloses a repeater for eliminating a near-far effect and relates to a repeater. The repeater comprises a downlink radio frequency link, an uplink radio frequency link and a monitoring unit, wherein the downlink radio frequency link consists of a donor duplexer, a lower low noise amplifier, a lower frequency selector, a lower power amplifier and a retransmission duplexer which are connected in turn; the uplink radio frequency link consists of a retransmission duplexer, an upper low noise amplifier, an upper frequency selector, an upper power amplifier and a donor duplexer which are connected in turn; the monitoring unit is connected with the lower low noise amplifier, the lower frequency selector, the lower power amplifier, the upper low noise amplifier, the upper frequency selector and the upper power amplifier respectively; and the upper frequency selector is a frequency selector for controlling the real-time power of a branch channel. The repeater has good covering effect, in particular for an edge covering region, can be used as not only a radio frequency selection repeater but also other types of uplink frequency selection repeaters.

Description

technical field [0001] The invention relates to a repeater, in particular to a repeater which eliminates the near-far effect. Background technique [0002] The main purpose of mobile operators' investment in wireless network construction is to improve user service quality by improving the network, and then improve its economic benefits; therefore, in network investment, the input-output ratio is an economic indicator that operators are very concerned about. Repeater, as a wireless network coverage product with low cost, rapid site construction, effective absorption of traffic, and high cost performance, is the preferred solution for mobile operators in many wireless coverage scenarios, such as underground parking lots, large shopping malls and supermarkets, etc. . [0003] As a two-way signal amplifier, the repeater performs transparent transmission and amplification of the signal. In the downlink, the base station signal is received and amplified, and then the signal is r...
