Wilson Electronics 844080

iDen Building Amplifier Kit w/ 800MHz Yagi, +70db Wilson 804080 Amplifier Only is a signle band iDEN 800 MHz Adjustable Gain In-Building Wireless Smart Technology II Signal Booster. Wilson Signal Boosters are bi-directional devices that deliver service levels consistent with what would be expected in areas of high cell network coverage. They amplify a weak or shadowed signal in mobile, M2M, marine and in-building applications. When using a Wilson Electronics Signal Booster in conjunction with Wilson Electronics antennas, the Outside Antenna will collect the cell tower signal and send it through the cable to the Signal Booster. The signal is then amplified and re-transmitted through the Inside Antenna into the room. Cell phones and cellular data cards in that area then communicate with the improved signal. When a cell phone or cellular device transmits, the signal is received by the Inside Antenna, amplified by the Signal Booster and transmitted back to the cell tower through the Outside Antenna.
