AppleInsider claims that Apple is planning on incorporating support for the new faster 802.11ac Wi-Fi specification into products this year. The new 802.11ac standard achieves much faster wireless networking speeds than the existing 802.11n specification (in use on the latest Mac, AirPort and iOS devices) by using 2 to 4 times the frequency bandwidth (from 80 to 160MHz), more efficient data transfers through sophisticated modulation, and more antennas (up to 8; existing standards support up to 4, while Apple's Macs currently use up to 3). This "Gigabit WiFi" offers speeds 3 times as fast as existing 802.11n wireless networks can with speeds of over 1 Gigabit per second.
