MULTI-AMPLIFIER BOOSTER FOR A WIRELESS COMMUNICATION SYSTEM

摘要

A multi-amplifier system includes a remote amplifier located near one or both system antennas. Locating the remote amplifier closer to the antenna improves the system performance while meeting regulatory limitations. The base unit may also have multiple remote antenna ports on one or both sides of the base unit allowing multiple remote antennas to be connected on that side of the base unit. A signal splitter with multiple antenna ports allows multiple remote antennas to be connected on the same side of the base unit. A remote amplifier located near each remote antenna removes the associated signal propagation losses from the regulated system performance. The base unit includes an amplifier detector for each remote antenna port to determine which output ports are connected to remote amplifiers. An automatic gain adjustment unit maintains the system gain, typically at the regulatory gain limit, based on the detected system configuration.

1. A wireless repeater comprising:
a first antenna; a second antenna;a first remote amplifier connected to the first antenna;
a base unit configured to supply amplified wireless communication signals to the first and second antennas in uplink and downlink channels, the base unit comprising a bidirectional amplifier having one or more output ports; a first cable connecting a first output port of the base unit to the first remote amplifier; the base unit further comprising a first detector operative for detecting the connection of the first remote amplifier to the first output port;the base unit further comprising an automatic gain adjustment unit operative for adjusting a first gain supplied to the first output port to achieve compliance with an output constraint while offsetting expected signal propagation losses on the first cable.
