China Mobile GSM 3G 4G Repeater Cell Phone Signal Booster Wireless Amplifier

China factory directly 3g 4g mobile signal cellular repeater

A mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals. The repeater device features easy installation & operation, build-in indoor antenna and no interference. It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house, home, office use.

Introduction To Mobile Phone Signal Repeater 1. Enhance Mobile Phone Signal Strength2. Improve Communication Quality3. Reduce Cellphone Radiation4. Protract Cellular Battery Life5. Economic Building Cost6. Easy Operation7. Easy Installation8. Build-in Power Supply

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.

1.Please make sure the outdoor antenna is well isolated with the indoor antenna(s). They should not be on the same horizontal line. The outdoor antenna should be on the housetop, at least 10 meters far away from the indoor antenna(s), better with stairs or wall(s) in between. Put the indoor antenna(s) in the middle of room, far away from the window and door.

2. If still no signal reception after activating repeater, please check if outdoor antenna points to signal tower or elsewhere have strong signal and check if strength achieve -70dBm. Please adjust the direction of the outdoor antenna until it catches good and steady signal. To ensure the result, the outdoor signal should be as strong as possible.
