Product Description

850MHz 1800MHz 2100MHz Tri Band Repeater Automatic Gain Control

 

Digital Tri Band 850 1800 2100MHz Band Selected Cellular Signal Repeater Amplifier

 

General :

The Repeater provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. 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 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.
