Description
Mostly, analog and digital RF repeaters are the two types of repeater used to amplify the mobile signal. Repeater, according to request, can be designed into single band, dual band, triple band and multi-band. Based on the amplifying effect, output power of the repeater can range from 13-43dBm and more. Repeaters can also be divided for indoor as well as for outdoor usage, and for consumer in household or for operator/entrepreneur in industry, infrastructure, etc.
The GSM850 RF Repeater (RFR) is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in GSM850 system. And its easy installation and maintenance can help carrier get fast return.
The repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
As per operator's working frequency, two types of RFR are available:
The band-selective function can amplify all signals in the whole band (bandwidth is customized).
The channel-selective function can amplify only the signals transmitted by the customized 1 (up to 4) channel.
Feature:
1. Aluminum-Alloy casing with IP65 protection for high resistance to dust, water and corrosion.
2. Supporting 5G/4G/3G/2G system
3. Low interference to BTS by adopting linear amplifier with high gain and low noise.
4. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink.
5. RJ45 port provides a link to a notebook for local supervision or IP Based NMS(Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater Via Ethernet or LAN.
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
