Wireless repeater with smart uplink

Image Number 9 for United States Patent #8116254.

An over the air repeater for enhancing wireless communication is provided. The repeater employs a system and method by which strong signals can be prevented from exceeding the repeater's uplink output limits while still providing full operational gain to any concurrently amplified weak signals, while adapting to time slot variations and optionally to frequency hopping variations. Power measurements are performed on each channel with resultant gain changes being performed on delayed versions of those same signals. Digital delay buffers are used to provide adequate processing time to make an accurate determination of the uplink signal levels of each RF carrier. The repeater alternatively monitors the downlink path from the donor base station to determine the frequencies to be processed on the uplink communication.
