The repeater makes the signal stronger in places with poor signal coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
Packaging Including:
1. Tri Band Booster
2. Power adapter
3. Outdoor Log-periodic antenna
4. Indoor Ceiling antenna
5. 5 meters cable
6. 20 meters cable
After installed booster signal not be very good, indoor signal coverage very small.
Solution 1: Adjust outdoor antenna's location and direction.
Solution 2: Check whether cable connected well.
Solution 3: Put more higher receiving antenna's position, which can received more good signal.
Solution 4: Change another bigger power booster.
Solution 5: Change another high gain receiving antenna.
How it works?
1. RECEIVES SIGNAL
The powerful antenna reaches out to access a good signal, and delivers it to the booster.
2. BOOSTS SIGNAL
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3. BROADCASTS SIGNAL
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
