According to Apple Insider Reports, Apple many intagrate 802.11ac ‘Gigabit’ WiFi to their upcoming devices. These new chips provides greater speeds than the one we use now. This new technology also improves the WiFi Range and reliability.
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).
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.
If Apple and other manufacturers deploy these chips we can expect long range wireless networks on our future dream gadgets.
