Whereas the standard 802.11n is still was not officially ratified, the IEEE starts already starts to consider its successor, with the data throughput reaching the Gigabit/s.
One is still in the early stages with this next standard, the frequency has not been fixed yet. They still hesitate between a frequency lower than 6 GHz close to Wi-fi 802.11a or to go much higher, towards the 60 GHz.
It will in any event be necessary to wait several years to profit from it, the IEEE is hoping to be able to set the standard in 2012-2013.
