Abstract
Apparatus and methods for signal booster systems with compensation for cable loss are provided herein. In certain configurations, a signal booster system includes two or more antennas for wirelessly communicating RF signals and a signal booster including booster circuitry for providing amplification to at least a portion of the RF signals. At least one of the antennas is connected to the signal booster via a cable. Additionally, the signal booster includes a cable loss compensation circuit that adjusts a gain of the booster circuitry to compensate for a loss of the cable.
Claims20
A signal booster system comprising:
- a plurality of antennas comprising a first antenna and a second antenna;
- a cable;
- a test signal injector configured to inject a test signal into the cable and a test signal detector configured to generate a detection signal in response to the test signal;
- a signal booster connected to the first antenna by way of the cable, wherein the signal booster comprises:
- booster circuitry configured to amplify a radio frequency (RF) signal received from the first antenna over the cable to generate a boosted RF signal transmitted on the second antenna;
- and
- a cable loss compensation circuit configured to adjust a gain of the booster circuitry to compensate for a loss of the cable based on the detection signal, wherein the detection signal indicates cable loss at a first radio frequency signal frequency, and the cable loss compensation circuit is further configured to extrapolate the cable loss at the first radio frequency signal frequency to estimate cable loss at a second radio frequency signal frequency.
