The GSM900 Mini Repeater provides an affordable solution to solve the indoor signal coverage problems

in telecommunication field 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.

The band-selective function can choose to amplify the signal within the customized band.


 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 signal level of uplink and downlink

 Simple installation with external AC/DC adapter


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, …
