Why we should buy mobile signal repeater/ signal booster/ GSM amplifier :
Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.
Unfortunately, there are still some places where one can find themselves “out of coverage”. Usually those places are either too far from the cell phone base station or located inside underground constructions, for example:
· Parking lots, tunnels
· Big stores, office buildings
· Cars, boats etc.
· House in remote areas
How is mobile phone signal repeater GSM/DCS/ 2G/3G/4G WORKING ?
•The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone amplifier through the connection cable (coax).
•After the signal is accepted by the phone amplifier, the device amplifies it.
•Then this amplified signal goes through the connection cable (coax) to the inside antenna.
•And after that, the amplified signal transmits to the cell phone.
A regular cell phone amplifier consists of:
· 1 - Outdoor antenna like YAGI antenna (including 10 meters standard cable) (you also can buy from us)
· 2 - Indoor omni antenna (you also can buy from us)
· 3 - 5 meters standard cable
· 4 - Power supply (DC 10v)
· 5 - User's manual
· 6 - Cell phone amplifier
Features of mobile phone signal amplifier
A. High-gain linear power amplifier
B . ALC and AGC function technology ,
C. Ultra-low noise receive amplifier
D. There is no interference to the base station ,right after the opening of the original system and the base station without the need to adjust parameters ,
E. Stable and reliable electromagnetic compatibility design .
F. The base station dose not cause an increase in background noise ,but will not lead to a decline in the quality of the base station communications
G. With full-duplex communication mode .
H. dispel the heat effective reasonable ,the structure is pretty ,the volume is suitable .
