Abstract
Radio frequency signal boosters are provided herein. In certain embodiments, a signal booster system includes a signal booster that is proximately located to an outdoor base station antenna. Implementing the signal booster system in this manner can provide a number of advantages relative to a configuration in which the signal booster is far from a base station antenna. For example, a long cable connected from an indoor signal booster to an outdoor base station antenna can be several meters long, resulting in significant cable loss that degrades transmit power and/or receiver sensitivity.
Claims20
A signal booster system comprising:
- an outdoor signal booster comprising:
- a base station antenna configured to receive a radio frequency (RF) downlink signal and to transmit a boosted RF uplink signal, wherein the base station antenna is directional, and
- booster circuitry configured to generate a boosted RF downlink signal based on amplifying one or more downlink channels of the RF downlink signal, and to generate the boosted RF uplink signal based on amplifying one or more uplink channels of an RF uplink signal;
- a shared DC power and RF cable;
- an indoor antenna unit connected to the outdoor signal booster over the shared DC power and RF cable, wherein the indoor antenna unit comprises a mobile station antenna configured to receive the RF uplink signal and to transmit the boosted RF downlink signal, and a booster control interface configured to control the outdoor signal booster;
- and
- an isolator/combiner circuit configured to provide power to the indoor antenna unit and the outdoor signal booster over the shared DC power and RF cable.
