IEEE 802.11 Publishes 4th Revision, Adds Greater Throughput

IEEE has published an update for its 802.11 standard, commonly referred to as WiFi. 802.11-2012 is the fourth major revision of the standard, following 802.11-2007 in 2007 and the initial release of the technology in 1997.

IEEE said that 802.11-2012 integrates defined MAC and PHY modifications for "much higher throughputs up to 600Mb/s", direct-link setup, fast roam, radio resource measurement, support for the 3650 - 3700 MHz band and vehicular environments, mesh networking, security, broadcast/multicast and unicast data delivery, interworking with external networks as well as network management.

“The new IEEE 802.11 release is the product of an evolutionary process that has played out over five years and drawn on the expertise and efforts of hundreds of participants worldwide. More than 300 voters from a sweeping cross-section of global industry contributed to the new standard, which has roughly doubled in size since its last published revision,” said Bruce Kraemer, who chairs the IEEE 802.11 working group.

The detailed specification is offered for $5 as a download or for $99 as a printed version.

    Looking forward to its release in products. Though i wonder about the health effects of so much high freq EM running around all over the place...

    For now it's only excititng if you're moving stuff across a local networki. Few of us around the world, and particularly in the US, even have the capability to use half of the speed and throughput that exists today. Don't get me wrong, it's a nice update and everything, but I fear it will mostly go to waste for the forseeable future.

Wireless N is pretty good, but sometimes just does not cut it.

Wireless company intranet is set to get a huge boost in throughput, as well as more mainstream uses like streaming local media and NAS. I'd guess that the number of people who see no benefit from increased WiFi bandwidth is quite low.

    Intranet is growing and surely this will be beneficial.

    Lets hope the rollout is a bit more organised than the .N standard. That damn Draft .N cost my company money.
