Don’t expect a revolution or a vast change in the way you use wireless. The IEEE 802.11ac standard, set to be in draft form by 2011, will mainly work with the current technology powering 802.11a. The new standard will continue to work on the 5.0Ghz band, but will provide larger channels for data throughput. Whereas current technology uses 20Mhz-wide channels, 802.11ac will be using either 40Mhz or 80Mhz-wide (and possibly 160Mhz) channels to deliver data. It’s the equivalent of adding a wide-mouth tab to your beer can, so your files will be able to flow more freely on your home network come 2012.
Plus this is the same group that took around 7 years to standardize 802.11n. 7 years in real time is like a million years in tech-time.
