Product Description

1800MHz 2100MHz 70dB Dual Band Signal Booster Repeater 2G 3G 4G

 

2G 3G 4G Dual Band Signal Booster 1800 2100MHz Mobile Signal Repeater Amplifier

 

General
The 1800/2100MHz Pico 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.
