WiGig Alliance Completes Multi-gigabit Wireless Spec
This is a nice setup where devices would use the higher throughput WiGig spec for short distance applications and automatically switch over to WiFi for longer distances. It could be used for wireless HDTV to eliminate wires including connections to other video sources. The beauty of the 60 GHz solutions is they are inherently short range due to the high absorption in air (oxygen molecules) so they will not interfere with other signals (and could be used for more secure military applications).
There are several standards vying for wireless HDTV applications such as lower frequency solutions like 802.11n/WHDI (5.8 GHz) and UWB (3.1 to 10.6 GHz) plus the higher frequency (60 GHz) solutions like WirelessHD, ECMA-387 and IEEE 802.15.3c. There was a nice article covering these different solutions in our August 2009 issue called “MM-waves in the Living Room: The Future of Wireless High Definition Multimedia.”
Which one do you think will win out and why???
