GSM Cell Phone Signal Repeater Booster Amplifier
Features:
1. ALC ensure output level stable and adjustable continuously.
2. Increases indoor signal coverage-up to 1000 sqm.
3. Supports multiple users simultaneously.
4. LED indicate and judge to signal level of uplink and downlink.
5. Decreases dropped or missed calls.
6. Full-Duplex Communication Mode.
7. Easy to set up – comes complete with everything you need.
8. Extends phone battery life (uses less power when signal is stronger).
9. CE authentication certificated.

Steps that describe the work of Repeater:
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal to the installed Repeater through the coax cable.
3) The Repeater accepts the low signal and amplified it.
4) The amplified signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the amplified good signal to your mobile phone.
