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 and operation, build-in indoor antenna and no interference. It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cell phones. A mobile phone repeater is ideal for house, home, office use. 3G UMTS 2100MHz 50DB Repeater

3G 2100MHz mobile networks are everywhere around the world but depending on where a mobile phone is located, regrettably the quality of the 3G 2100MHz signals differ significantly from excellent to poor. The item in auction is designed to address the signals strength issue by boosting the signals in two directions (Full Duplex) :

1. signals transmitted from a mobile phone are received by the 3G 2100MHz booster over the air via the booster's indoor antenna and these signals are amplified and retransmitted over the air via the booster's outdoor antenna to a nearby cellular phone site .

2. signals transmitted from a cellular phone site are received over the air by the 3G 2100MHzbooster via the booster's outdoor antenna and these signals are amplified and retransmitted over the air via the booster's indoor antenna to a mobile phone. The 3G 2100MHz Booster can be viewed as an intermediate agent to help to set up a reliable wireless link between a mobile phone and the 3G 2100MHz mobile networks infrastructure. The Booster is particularly useful in zones with poor 3G 2100MHz coverage such as basements, car parks and tunnels. It can also be used in offices, homes, supermarkets, cinemas and hotels etc to enhance the 3G 2100MHz signals for better voice and data communications.
