On Tuesday, the Wireless Home Digital Interface (WHDI) Consortium announced that the wireless technology specification for HD transfer has reached a "completed state." This means that the new standard allows consumers to throw around uncompressed HD data throughout the house by way of wireless connections. The specification had been in the works since the summer of 2008.

“WHDI is the only solution that meets consumers’ expectation and demand for a high-quality, multi-room HD wireless solution,” said Leslie Chard, president of WHDI LLC. Adding that: “WHDI further enables two of the strongest trends in the A/V universe: the proliferation of HD content sources (now including the PC and mobile devices) and the increasing number of inexpensive, high quality displays placed throughout the home.”

The new specification supports uncompressed data rates up to 3 Gbps in a 40 MHz channel in the 5 Ghz unlicensed band. The specs also provide a range beyond 100 feet (through walls), with a latency less than one millisecond. "WHDI relies on HDCP revision 2.0 to provide superior Hollywood-approved security and digital content protection," the Consortium revealed.

The technology behind the specification, according to Electronista, was founded by chip designer Amimon, and is one of (at least) four technologies that will bring wireless HD to the household. When products become available, consumers will be able to stream 1080p video at 60 Hz refresh rates and 12-bit color depth. Look for products to hit the market in Fall 2010.
