SiBEAM Goes 60 GHz
Posted by samc on June 27th, 2007Startup SiBEAM today revealed its new WirelessHD chipset, designed to “make wireless multi-gigabit throughput a reality”, in the home.
SiBEAM’s operates in the 60 GHz or ‘millimeter-wave’ unlicensed band, with 7 GHz of frequency bandwidth. Technology competitor UWB operates from 1.5 to 7.5 GHz, while 802.11n uses one or two 20 MHz-wide channels (generally in the 5 GHz band). SiBEAM uses adaptive beam-steering technology that takes advantage of the directional nature of 60 GHz signal.
“Wireless USB“, using UltraWideband and the WiMedia spec, can deliver 480Mbps 10 feet or so, but HDMI and DVI cables deliver data rates in the gigabit range. That’s where Wireless HD comes in.
SiBEAM says the main advantage of unlicensed 60 GHz is that compression chips are not needed for HDTV, since it can handle the gigabit speed required by baseband HDTV (video).
