802.11ac approved

The IEEE has finally announced approval of IEEE 802.11ac amendment to the 802.11 standard.
It seems like we waited forever.
Understandably makers were keen to sell us products that take advantage of it before it was finalised; that created the expectation.
As long as buyers are made aware of the risks associated with early adoption I am happy to have that choice.
802.11ac is expected to be an important step in Wi-Fi, but as it operates in the 5 GHz band only its shorter range will increase system costs where more access points are required to get coverage.
