Functions of 900MHz GSM Repeater Coverage 2000sqm/Gain73dB:

In some places such as tall buildings, basement of the room, countryside, your cell phone can not receive the signal well. Then, a repeater can help you. Mobile phone signal repeaters are able to pick up weak cellular signal from a BTS and transmit them to your mobile phone, and then transmit a more powerful signal back to the BTS.  Mobile phone signal repeaters overcome the problem of dropped calls, limited range and slow data rates.  

Our booster can increase the signal by 500%
