Apple working to adopt 802.11ac 5G Gigabit WiFi this year

Apple is expected to rapidly deploy support for the new 802.11ac specification this year, adding so called “Gigibit WiFi” to new AirPort base stations, Time Capsule, Apple TV, notebooks and potentially its mobile devices.

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).

While not yet finalized as an official standard by the 802.11 Working Group, progress on the new standard is occurring faster than previous efforts in wireless networking have.

Multiple suppliers have already issued chipsets supporting 802.11ac for consumer grade applications. Key Apple component maker Broadcom announced chips supporting the standard earlier this month at CES.

In addition to reaching networking speeds above 1 Gigabit (about three times as fast as 802.11n networks can manage), 802.11ac promises better networking range, improved reliability, and more power efficient chips, thanks to parallel advances in reducing chip size and enhancing power management.

Apple popularizes WiFi with AirPort

While Apple wasn’t the first company to sell wireless devices, it was first to bring the technology into the mainstream beginning in 1999, when Steve Jobs dramatically demonstrated Apple’s initial AirPort technology onstage at the July Macworld Expo as “one more thing” after showing off the company’s new consumer iBook notebook.

Jobs pretended to hold his new iBook notebook up to provide a clear view for the camera operator, but he then continued to use the web as he walked across the stage to the delight of the audience that suddenly realized the new notebook had a wireless connection.
