Abstract

Methods and systems for antenna switching for time division duplexing (TDD) in a 60 GHz distributed communication system are disclosed and may include enabling one or more antenna configurations in one or more remote RF modules within a wireless communication device based on a measured signal characteristic. The RF modules may receive IF signals generated from baseband signals via one or more coaxial lines. TDD RF signals may be communicated via the antenna configurations with devices external to the wireless communication device. The IF signals may be tapped in the coaxial lines at taps coupled to the RF modules. The baseband signals may include video, streamed Internet, and/or data from a local data source. The TDD RF signals may be transmitted to a display device. Control signals for the RF devices may be communicated utilizing the coaxial lines.
