Abstract

Methods and systems for communication via subbands in a 60 GHz distributed communication system are disclosed and may include enabling one or more antenna configurations in remote RF modules within a wireless communication device based on a measured signal characteristic. The RF modules may receive IF signals from baseband signals via one or more coaxial lines. Output RF signals may be communicated in frequency subbands via the antenna configurations with external devices. The IF signals in the coaxial lines may be tapped at taps coupled to the RF modules. The baseband signals may include video, Internet streamed, and/or data from a local data source. Frequency division duplexed signals may be communicated to a display device. Control signals may be communicated utilizing the coaxial lines. The signal characteristic may include a received signal strength indicator, and or a bit error rate. The output RF signals may include 60 GHz subband signals.
