Signal Booster (Repeater Amplifier) for 2G/4G reception indoors

A mobile signal booster system improves indoor 2G/4G reception by capturing a weak outdoor mobile signal and rebroadcasting it inside a building. It is commonly used where devices such as the CPR Guardian Watch struggle to maintain a reliable connection indoors. For the CPR Guardian watch, this setup can provide more reliable indoor connectivity for GPS tracking, voice calls, alerts, and emergency communication in areas with poor mobile reception such as care homes, rural properties, thick-walled buildings, or basement rooms. How does it 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 CPR Guardian Watch (can also be used to improve your mobile phone reception). How to Install: 1) Fix the outdoor antenna outside the house or window (ideally in sight of your nearest mobile mast) 2) Connect outdoor antenna to BTS port in repeater box with the supplied cable. 3) Connect indoor antenna to MOBILE port in repeater box. 4) Plug power adaptor into AC power socket in repeater box. Installation is finished.
