The Wireless Gigabit Alliance (WiGig) is an organization advancing the adoption and widespread use of 60 GHz wireless technology worldwide. They recently announced the completion of a unified wireless specification that enables high performance wireless display and audio and provides data transfer rates more than 10 times faster than today’s wireless LANs, extending WiFi technology while supporting backward compatibility with existing WiFi devices. The completed specification is now ready for member review and is anticipated to be made available to WiGig adopter members in Q1 2010.
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???
