1. A method for wireless communication, the method comprising:
- in a wireless communication device comprising a body and a plurality of remote RF modules within said body of said wireless communication deviceamplifying IF signals with a power amplifier in a final amplification stage to create amplified IF signals that are analog signals, the IF signals having been upconverted from baseband signals;
configuring one or more antennas in said plurality of remote RF modules based on a measured signal characteristic, wherein each of said plurality of remote RF modules receive the amplified IF signals via one or more coaxial lines within said body of said wireless communication device;
directly upconverting the amplified IF signals to RF;
communicating low frequency control signals via the one or more coaxial lines for the plurality of remote RF modules; and
communicating time division duplexed RF signals, via said one or more antennas, with one or more devices that are external to said wireless communication device based on said configuring.

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.
