(WIRELESS High Definition) A short-range wireless video technology from the WirelessHD Consortium. Using the unlicensed 60 GHz band, WirelessHD (WiHD) transmits 1080p HD video from a data source to a TV within approximately 30 feet. With a data rate of 28 Gbps, Version 2.0 of the standard is capable of handling very high-speed data, including 3D and 4K video resolutions.At 60 GHz, the five-millimeter wavelength is highly directional. However, in 2007, SiBEAM demonstrated CMOS chips that can bounce the signal off walls and objects using an array of up to 36 antennas on a 1" square surface.
