AppleInsider claims that Apple is planning on incorporating support for the new faster 802.11ac Wi-Fi specification into products this year.
This "Gigabit WiFi" offers speeds 3 times as fast as existing 802.11n wireless networks can with speeds of over 1 Gigabit per second.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).
Despite the specification not being finalized, Broadcom has already announced a family of chips supporting 802.11ac Wi-Fi. The final specification is expected to be certified in the second half of this year.
Apple and other manufacturers have been known to deploy un-finalized wireless technology in the past. Apple deployed 802.11n in new AirPort base stations years before the official standard certification.
