The IEEE has recently begun the first steps of voting on a major improvement to Wi-Fi standards due in two years. The 802.11ac standard should upgrade 802.11a to use 80MHz or even 160MHz channels that provide much more bandwidth than today. Combined with about a 10 percent increase in efficiency for modulating the actual frequencies, the speedup should improve the theoretical transfer speeds to as much as 1Gbps, or more than three times the 300Mbps 802.11n reaches for now.
