SYSTEMS AND METHODS FOR ADAPTIVE REPEATERS
First Claim
1. A method comprising:
- receiving a first radio frequency (RF) signal portion of an RF signal at a wireless repeater at a first time, the RF signal being communicated from a transmitter and directed over a communications path to a receiver, the wireless repeater operating in a repeater mode at the first time, the wireless repeater being in the communications path between a first portion of the communications path and a second portion of the communications path;
downconverting the first RF signal portion to a first lower frequency (LF), thereby generating a first LF signal portion;
determining a first signal quality value of the first LF signal portion;
evaluating whether the first signal quality value satisfies a first signal quality condition indicating that a signal quality of the RF signal has sufficiently degraded over the first portion of the communications path;
when the first signal quality value satisfies the first signal quality condition, switching the wireless repeater to a regenerator mode, receiving a future RF signal portion, downconverting the future RF signal portion to a future LF signal portion, demodulating the future LF signal portion to data, and remodulating the data to a second LF signal portion;
when the first signal quality value does not satisfy the first signal quality condition, maintaining the wireless repeater in the repeater mode, and passing the future LF signal portion as the second LF signal portion;
upconverting the second LF signal portion to a second RF signal portion; and
transmitting the second RF signal portion to the second portion of the communications path.

Abstract
In some embodiments, a first RF signal is received at a wireless repeater, a signal quality is determined based on the first RF signal, the signal quality is analyzed based on a parameter, an operation mode is auto selected based on analysis of the signal quality, and a second RF signal based on the first RF signal is generated for transmission according to the selected operation mode. Under one mode, a first RAC of the wireless may generate data based on a first IF signal downconverted from a first RF signal. Based on the data, a second RAC of the wireless repeater may generate a second IF signal, which can be used to generate a second RF signal for transmission. Under another mode, the first RAC may provide the IF signal to the second RAC, which provides the IF signal for generation of the second RF signal.
