60GHz Uber-WiFi Proposed By New WiGig Group
judgecorp writes "A new vendor group has promised a Gigabit wireless specification by the end of this year. The Wireless Gigabit (WiGig) spec is apparently 80 percent done and, since it is aimed at high-definition TV, it has to go at more than 3Gbps. There's around 7GHz of spectrum freely available in the 60GHz band, so it's technically feasible, and with all the major Wi-Fi silicon vendors on board (as well as Microsoft, Dell, Nokia and others) WiGig looks to have the political muscle too. They should be aware of the Sibeam-led WirelessHD group, though, already in the 60GHz space, and Ultrawideband (UWB) is not dead, as there are actual, real UWB products."
accptable quality at 720p is one thing, but excellent quality at 1080p is another
Security for the user, probably no more than ordinary wi-fi. Security against the user? Well, if this is designed to transport "premium content" you don't even have to guess.
It means that there is a 7 GHz wide range of frequencies that is free somewhere around 60 GHz.
e.g. 60-67 might be a possibility, or it might be 57-64.
It's easier to use 7 GHz of spectrum at 60 GHz than 7 GHz of spectrum centered at 10, because the range is a lower percentage of the center frequency of the range.
That said, the range at 60 GHz is going to be insanely short.
retrorocket.o not found, launch anyway?
Hopefully this will be rolled into IEEE 802.11 at some point. Otherwise things could become a mess (even if this consortium has major backing).
