A number of top TV manufacturers together with chip design company Sibeam have begun working on a wireless system that can replace current cabling solutions for delivering high-definition signals between electronics products around the home.
The WirelessHD Special Interest Group includes the likes of Samsung, Sony, Panasonic, LG, NEC and Toshiba.
WirelessHD is set to use an unlicensed portion of spectrum around 60GHz which should allow gigabit-per-second (possibly up to 5Gbps) streaming of full HD (1080p), at distances up to 30 feet.
The 60GHz spectrum was chosen because it has a huge amount of bandwidth available, and a high allowable transmit power (8 watts in the US). Technical problems associated with this include the appliances having to be in line of sight of each other, therefore error-correction and smart antenna technology would need to be built in to the system.
WirelessHD would also have to play with HDCP and any other copy-protection systems in place, but then that's true with any communication system used to transfer HD signals.
Other technologies already in development include the 802.11n draft specification that a number of manufacturers are already working on, though this won't necessarily reach the speeds required for multi-streaming of full HD content, and Ultra Wideband Technology being worked on by Tzero. WirelessHD might be ready sometime in 2008.
