How the StellaRoom900 signal booster works
The receive antenna is installed where you have a good signal.
This is usually on your roof, but can also be outside a window.
This antenna will receive the gsm signal and send it down the coaxial cable to the gsm signal booster which is placed in the room where you want coverage.
The gsm signal booster then amplifies this signal and transmits it into the room.
Your mobile phones and laptops nearby can now communicate with the improved gsm signal.
When a mobile phone transmits during a call, the signal is received by the booster, amplified, and then transmitted back to the network base station via the panel antenna.
The StellaRoom900 gsm signal booster is designed for residential use, with coverage for 400m2(up to 2 rooms).
