Single Band Pico Repeater
|
|
The repeater is working as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Features
- Two signal ports with full duplex design
- 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
- Unique color LEDs to indicate power supply and state and alarm
- Simple installation with external AC/DC adapter
Application
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
