90dB High Gain Wireless Selective Mobile Signal Repeater GSM 900MHz 37dBm
Descriptions:
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
