The BU33 Series Repeater is compact in size and light in weight. Hence, the installation of the BU33 Series Repeater is easy, simply just plug and play (installation simplicity, and operational user friendliness). With the control panel in front of the repeater, the repeater status can be known during installation.
 
Compare to the worldwide repeater brand, the BU33 series has a smart function called which can be activated via the front panel. This smart function can prevent UL interference and self-oscillation caused by insufficient isolation between donor and service antennas, and also setup parameters and keep optimal condition automatically; the only thing for users is just activating this function by front panel. The BU33 series has Auto Level Control.

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  , …
