GSM 900MHz Ics Pico Repeater , Digital Signal Booster
Model: VR-1575-G-I
Product Instructions
The GSM900 PICO Repeater 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 GSM900 system. And its easy installation and maintenance can help carriers 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.
Product Features
- High system gain
- Linear power amplification to effectively suppress inter-modulation and spurious emission
- Smart Automatic Level Control (ALC) ensures output level stable and adjustable continuously
- Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
- Working frequency bandwidth adjustable
Applications
- To expand signal coverage or fill signal blind area where signal is weak or unavailable.
- Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots
