2G 4G Mobile Phone Signal Repeater Booster Cell Phone Amplifier 1800MHz Network Booster


The 1800MHz 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.

2022 new upgraded Micro power smart single band signal repeater for residential use with WIFI monitoring and control function, it could cover 100- 300sqm (standard kit), and could support max 2 to 3 indoor antennas to cover over 800sqm. Analog repeater and Digital(Customized Selective Band) repeater for Choice.
