The 4G AWS 70, Wilson's latest cell phone signal amplifier, is a professional grade signal booster designed to improve the 4G AWS network by T-Mobile. Designed to support all the latest smartphones, (iPhone, Android Phone, Blackberry, Windows phone, etc), it will provide you with a strong 4G signal in any building. Perfect for offices, homes or even larger buildings, the 4G AWS 70 requires a set of two additional antennas (exterior & interior) as well as cables. The 4G AWS 70 features adjustable gain controls for both uplink and downlink and provides 70dB gain on average. This allows an optimized installation by making the antenna placement less critical and by adapting it to the requirements of the building it is installed in. The 4G AWS 70 by Wilson will thus put an end to dropped calls or slow browsing on your mobile phone. But it will also preserve your device's battery, the signal source being much closer and stronger.
