  • Patent number: 11601190
    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.
    Type: Grant
