WHDI - Wireless High Definition Interface sets a new standard for wireless high-definition video connectivity. It provides a high-quality, uncompressed wireless link which can support delivery of equivalent video data rates of up to 3Gbit/s (including uncompressed 1080p) in a 40 MHz channel in the 5 GHz unlicensed band, conforming to FCC regulations. Equivalent video data rates of up to 1.5Gbit/s (including uncompressed 1080i and 720p) can be delivered on a single 20 MHz channel in the 5 GHz unlicensed band, conforming to worldwide 5 GHz spectrum regulations. Range is beyond 100 feet (30 m), through walls, and latency is less than one millisecond.
