The ICREON Wireless USB Multi Adapter HUWB-3000 uses Ultra Wideband to connect any windows based computer to your HDTV or projector wirelessly through VGA or HDMI connections and 5.1CH speaker and stereo speaker wirelessly through S/PDIF or stereo connections. It sends video and audio wirelessly through a WUSB link between a PC and a HDTV at speeds up to 220 Mbps using UWB technology from Alereon.
UltraWideBand and Wireless USB looked promising five years ago, but were delayed by fractious in-fighting and largely supplanted by Wireless HDMI and high throughput WiFi.
“Wireless USB” using UltraWideBand as a cable replacement was a great concept, but it never got off the ground. Several UWB vendors ceased operations during 2008 and 2009. Today, UltraWideBand is all but dead in the consumer marketplace although Staccato and Alereon, still manufacture ultrawideband chips.
WiGig 1.0, paves the way for tri-band Wi-Fi routers as early as 2010. WirelessHD, originally proposed by chipmaker SiBeam, can use the same 7GHz of continuous bandwidth at 60 GHz to send uncompressed HD video but does not fall back to 5 GHz.
The Wireless Home Digital Interface (at 5GHz) claims speeds that are “equivalent” up to 3 Gbit/s (including 1080p/60Hz), using a 40MHz channel in the 5GHz unlicensed band. What “equivalent” means is anyone’s guess. WHDI’s secret sauce prioritizes the most visually significant bits of a video stream with error correction.
Quantenna (at 5 GHz) uses the Wi-Fi protocol 802.11n in the 5 GHz band and multiple antennas to transfer video. Quantenna combines 4×4 MIMO, transmit beamforming, vector mesh routing, and two or four concurrent bands for link rates up to 1 Gbps.
