Amimon uses the same 5GHz unlicensed band of spectrum as 802.11a, although
its WHDI technology uses its own protocols. The company claims that it can use
two 20MHz channels to transmit 1080p video wirelessly 100 feet, through walls.
The technology has already been proven; Sharp began shipping an
Amimon-based wireless HDTV
earlier this year, about eight months after Amimon shipped its first

Last year, Sanyo demonstrated a wireless projector using the chip set, and
three more OEMs demonstrated WHDI-based TVs: Loewe, XOCECO and Funai. The
latter company serves as an ODM for top brands including Mitsubishi and
All of those TVs, however, will be using what Noam Geri, Amimon's vice
president of marketing, calls "pre-standard" technology. In 2008, the
SIG companies will agree on a standard, which will then be put into production
next year, Geri said. There will be a logo that will be used to identify
compatible components: "Without a connector, the logo will be the only way
the consumer can tell that they will interoperate," Geri said.
