There is much more to 802.11y than just simply the frequency.
The most interesting to me is:
Extended channel switch announcement (ECSA)- provides a mechanism for an access point to notify the stations connected to it of its intention to change channels or to change channel bandwidth. This mechanism will allow for the WLAN to continuously choose the channel that is the least noisy and the least likely to cause interference. This mechanism will also be used in 802.11n, which will allow devices to switch between .11y operation and .11n operation in the 2.4 and 5 GHz bands.
