Wireless 8 Band Selective Repeater RF Cell Signal Amplifier Large Area




Outdoor Repeater is an important part of the mobile network wireless coverage construction. It mainly receives processes and amplifies RF signal, in this way extends the BTS coverage.

For most outdoor repeater layout area, generally no fiber resources but can receive the base station signal, wireless repeater can be used to solve the coverage problem.
Use of wireless repeater, should pay attention to the following points:
● To reduce interference to the donor base station and expand the coverage area, isolation of the wireless signal is particularly important, which requires the signal amplified to be more pure
● For towns or remote areas, due to the volume of teletraffic is not high, normally the required coverage is the larger the better
● In suburban areas, mainly to solve the coverage or poor call quality small area
● Coverage for residential built-up areas, considering using repeater plus branch and trunk amplifier and a small number of service antennas to cover

Outdoor repeaters offer different solutions for a variety of signal blind, weak areas. The main application are:
● Expand the scope of services and eliminate the signal blind areas formed by, such as mountains, buildings, trees and other obstructions
● Erecting along the high way, improve coverage efficiency
● To solve the indoor coverage issues of the larger buildings which is temporarily unable to implement indoor distribution system
● Lead the signal of idle base station to the coverage area of busy base station to achieve easing the high teletraffic
● Deeply coverage in dense residential area (For those residential communities with many high-rise residential buildings, indoor coverage should be considered in)
● Due to terrain reasons, the base station signal is not directly covered and the use efficiency is low, etc


8 Band Selective Repeater Application:
To expand signal coverage of fill signal blind area where signal is weak or unavailable.
Indoor: Hotels, Home, Basements, Shopping Malls, Offices, Parking Lots, etc
Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, highways
