HDTV via WiFi expected this summer
Celeno Communications, an Israeli startup backed by Cisco, has created a technology it says upgrades the transmission part of a WiFi network to make it robust enough to deliver multiple high-definition television (HDTV) streams. The semiconductor manufacturer said the technology, which will work with existing receivers such as set-top boxes already in the home, is in field trials and will be ready this summer.
The technology, called OptimizAIR, uses 5 GHz spectrum and uses standard PHY and MAC layers but includes proprietary algorithms to double the throughput of standard 802.11 WiFi and increase signal range by a factor of eight. Celeno said it can stream HD video 120 feet, through four brick walls and more than three floors.
The OptimizAIR is designed to be integrated into broadband access gateways, allowing end users to stream video from PCs to TV sets and other consumer electronics devices.

HD iptv has been in development by guys like me for 5 plus years now. how is using 5 ghz band wifi anyway , since wifi runs on 2.4 ghz and not 5. sounds like more smoke and mirrors. now you want to see great IPTV, visit zulu.com and see how its supposed to be done with just a simple PC and broadband access....

Sorry to correct you, but 802.11A uses 5ghz band, but has limited distance. My understanding is that 802.11N will use a combination of 2.4ghz and 5 ghz to obtain its remarkable speed. Thats were I see WiFi and HD and IPTV will work.
