900/1800/2100MHz Tri Band Three LCD Display Screen Mobile Phone Signal Booster 2/3/4G Cell Phone Signal Repeater Signal Amplifier Set

The device is featured by easy installation and operation and no interference. It is the perfect device for boosting mobile phone signal. A mobile phone repeater could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones.

Features:
Large-capacity signal response technology, support multi-person call, continuous on line, make signal more stable, communication is smoother.
Adopt high-tech comber, which has fine isolation effect and higher communication bandwidth load, with processor, realize multi-frequency non-interference, multiple people talk smoothly at the same time.
Rectangular filtering technology effectively reduces signal noise and concentrates output power in the effective frequency band.
Using three-core control processor with high accuracy three display screen to display signal values in real time.
Thickened metal body has strong heat dissipation ability and strong anti-interference.
The coverage area is wide enough to meet the needs of most places,  such as high-rise buildings, elevators, office buildings, basements, KTV, yachts, urban villages, tunnels, remote mountainous areas, etc.
Improve the coverage of sending and receiving mobile phone signals.
Reduce the radiation of the mobile phone to the human body.
Extend the time and life of the mobile phone battery.
Easy to install, environmentally friendly, small size, flexible configuration according to specific application occasions.
Full-duplex work, high isolation between uplink and downlink, will not interfere with each other.
With advanced digital filtering technology, out-of-band rejection is particularly fine.
The outdoor overflow signal is small and does not interfere with the base station receiving sensitivity.
