- Template:Note labelTemplate:Note label IEEE 802.11y-2008 extended operation of 802.11a to the licensed 3.7 GHz band. Increased power limits allow a range up to 5,000 m. As of 2009[update], it is only being licensed in the United States by the FCC.
- Template:Note labelTemplate:Note label Assumes short guard interval (SGI) enabled, otherwise reduce each data rate by 10%.
