The Indoor Signal Repeater provides an affordable solution to solve the indoor signal coverage problems in system 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.
 
 Features:
* 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.                                                                                                                                        
* Provide quick coverage solution for small signal weak & block zones. Reduce drop/off calls.                                                                                                          
* Compact size, low consumption, easy installation, great cover.                                                                                                               
* Cover about 5000~30000 m² without block or obstruct.
 
Applications:
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  , …
