Digital dream: Cable-free connections on the way
LG, Panasonic, NEC, Samsung, SiBeam, Sony and Toshiba have joined forces to begin developing a HD wireless standard, while wireless USB devices should hit the shops before the end of this year
LG, Panasonic, NEC, Samsung, SiBeam, Sony and Toshiba have joined forces to begin developing a HD wireless standard, while wireless USB devices should hit the shops before the end of this year.
The idea behind wireless highdefinition (HD) is to make HD hardware a more appealing proposition for home consumers.
The seven firms involved in developing the standard aim to make use of the unlicensed 60GHz frequency band and plan to name the standard WiHD or Wireless HD.
The companies reckon this wireless standard will make setting up high-definitionready home theatre systems a significantly easier task, as cabling should no longer prove to be a limiting factor between source and destination devices (such as HD or Blu-ray movie players and HD TVs).
The first iteration of the standard will offer bandwidth of between 2Gbits/sec and 5Gbits/sec, though the core technology allows for a theoretical maximum of up to 20Gbits/sec.
This standard will be the first wireless design that offers sufficient bandwidth to combine uncompressed high-definition video, multichannel audio (surround sound), intelligent format and control data in addition to Hollywood-approved digital content protection.
WiHD will also be designed with compatibility in mind so that it will coexist with existing wireless standards.
Meanwhile, also on the wireless front, wireless USB products are expected to see the light of day, at least globally, by the end of this year. The WiMedia Alliance, led by Intel and supported by many other firms including HP and Sony, is planning to use Ultra Wide Band (UWB) technology as the backbone for wireless USBÃƒÂ¢Ã¢â€šÂ¬Ã¢â€?Â¢. This can deliver data rates of up to 480 megabits per second at a range of three meters, with transfer speeds then decreasing as the range increases up to a maximum of 10 meters.
