"This will truly enable advanced home-networking applications such as multichannel CD-quality audio and DVD-quality video to operate at maximum efficiency without performance or range limitations," Larry Ciaccia, vice president of GlobespanVirata's wireless product group, said in a statement.

That standard is not expected to be finished for several years.
The GlobespanVirata upgrade still allows the networks to be compatible with standard 802.11g and 802.11a clients and does not cause interference with other networks, according to Jim Zyren, director of marketing at GlobespanVirata. Zyren added that while compressed audio and video will be transferred wirelessly at higher rates, content such as encrypted data will not.
