How our boosters work
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal through the coax cable to the installed Repeater.
3) The Repeater accepts the low signal and improves it.
4) The improved signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the improved good signal to your mobile phone.
Checks before purchase
The signal booster device can only boost the mobile signal from base station, it does not create a signal, therefore make sure there is at least 1 bar before purchasing.
The signal booster coverage depends on the outside signal strength received by the outdoor antenna .The coverage gets wider if signal strength is strong. But if the outdoor signal strength is lower than -85dbm ,please contact us before placing order .
Use the following codes to check signal strength using mobile phone :
Iphone :Please dial: *3001#12345#*，and see the signal strength number on the top left corner
Android: Please dial *#*#4636#*#*，and see the signal strength number in “Phone information"menu.
