Abstract
Provided herein are apparatus and methods for radio frequency signal boosters for cellular and broadcast television signals with Wi-Fi signals transmission function. Cell phone, Wi-Fi, and broadcast television signals are boosted and retransmitted over a shared antenna or over more than one antenna. In certain implementations, a multi-band signal booster is configured to provide signal path gain to at least three signal paths: a first signal path configured to receive a first time division duplexed Wi-Fi signal, a second signal path configured to receive a first frequency division duplexed mobile or cellular signal, and a second signal path configured to receive a broadcast television signal.
Claims20
An electronic system for boosting time division duplex (TDD) and frequency division duplex (FDD) signals, the electronic system comprising:
- a signal booster comprising:
- a diplexer configured to receive an FDD uplink signal and a TDD uplink signal from a cable, and to output the FDD uplink signal at a first terminal of the diplexer and the TDD uplink signal at a second terminal of the diplexer;
- a TDD circuit including a TDD uplink signal path configured to amplify the TDD uplink signal to generate an amplified TDD uplink signal, and a TDD downlink signal path;
- and
- an FDD circuit including a first FDD duplexer configured to receive the FDD uplink signal, a second FDD duplexer configured to output an amplified FDD uplink signal, an FDD uplink signal path having an input connected to the first FDD duplexer and an output connected to the second FDD duplexer, and an FDD downlink signal path having an input connected to the second FDD duplexer and an output connected to the first FDD duplexer.
An electronic system for boosting time division duplex (TDD) and frequency division duplex (FDD) signals, the electronic system comprising:
- a signal booster comprising:
- a TDD circuit including a TDD downlink signal path configured to amplify a TDD downlink signal to generate an amplified TDD downlink signal, and an TDD uplink signal path;
- an FDD circuit including a first FDD duplexer, a second FDD duplexer configured to receive an FDD downlink signal, an FDD uplink signal path having an input connected to the first FDD duplexer and an output connected to the second FDD duplexer, and an FDD downlink signal path having an input connected to the second FDD duplexer and an output connected to the first FDD duplexer;
- and
- a diplexer configured to receive the amplified TDD downlink signal from the TDD circuit at a first terminal and to receive an amplified FDD downlink signal from the first FDD duplexer at a second terminal, the diplexer further configured to output the amplified TDD downlink signal and the amplified FDD downlink signal to a cable.
