Wilson PCS Amplifiers extend cellular services in poor coverage areas by amplifying both transmit and receive signals. The amplifiers reduce problems with signal fades and dropped calls while improving voice quality, service range and access. These multi-mode amplifiers are designed to offer a cost-effective solution for use in buildings. Wilson Cellular amplifiers are network compatible and enhance the cellular phone user's satisfaction without comprising the operation of the cellular system.

This Amplifier-Repeater greatly improves signal strength inside a building when using your cellular phone. It does this without a physical connection to your phone, allowing you to walk freely during a call. It even allows multiple phones to be used simultaneously.

The signal from the cellular tower is received by the outside antenna and then amplifier and repeated to your phone through the inside antenna. When the phone transmits it is received by the inside antenna and then amplified/repeated through the outside antenna to the cellular tower.

Coverage area is primarily determined by the strength of the outdoor signal and the gain of the amplifier. To determine correct amplifier size, see chart above and documents below.

Antenna Separation:

In order for your system to function properly, you must maintain adequate separation between the interior and exterior antennas. The following rules will help you maintain adequate separation:

• Ensure that the exterior Yagi antenna is aimed away from the interior dome antenna.

• Ensure that you have 45' of separation between the interior and exterior antennas when using the 50dB Amplifier and 70' of separation between the antennas when using the 65dB amplifier or higher. Of that, at least 20' should be vertical separation (the Yagi should be mounted at least 20' higher than the interior panel antenna.)

How dB Affects Coverage:

A 6dB increase in signal doubles the interior coverage distance while a 6dB decrease will halve your interior coverage distance. Likewise, a 3dB increase will increase the interior coverage distance by 43% and a 3dB decrease will decrease it by 30%.
