Wireless HD to debut at CES
The much anticipated annual Consumer Electronics Show (CES) begins this Monday (Jan. 7th) in Las Vegas, where plenty of new technologies are sure to be unveiled. Wireless HD, though not a new concept, has finally become a reality and will be on display at this year's CES. Several companies will be showing off their versions of wireless HD including the aptly named WirelessHD group, Westinghouse and LG.
WirelessHD, a consortium of companies including Sony, Toshiba and now Intel among others, has announced its completion of a chip that will allow HD signal to be beamed from DVD players, cameras, set-top boxes, etc. to the television set without compressing the signal, which can lessen the quality. Their technology uses the 60 GHz frequency of the radio spectrum, which is basically unused, thus allowing it to avoid interference from other wireless devices. The range is also limited to about 10 meters so neighbors can not tap into the signal, a feature that allays the concerns of the Motion Picture Association of America. See more here
Another wireless HD television will be introduced by Westinghouse, who has teamed up with chipmaker Pulse-Link Inc. to produce the Digital Wireless HDMI HDTV. This 47" LCD will not be available to to the home market initially, but is aimed at the retail and public display markets. It will come with a transmitter that can beam High Definition Multimedia Interface (HDMI) signal up to 40 feet. It is slightly slower than the 60 GHz technology and requires some compression.

LG will also be displaying an LCD and a Plasma wireless HDTV. Their products rely on regular Wi-Fi technology which is considerably slower than the other two technologies. At 47" and 52" respectively and with a 50' range, LG's wireless HDTVs will be available to the public earlier than the others, sometime early this year.
