"...In early 2013, the Wi-Fi Alliance will launch its 802.11ac testing, designed to certify 802.11ac interoperability of different 802.11ac products and brands. The "Wi-Fi Certified" brand will help to make 802.11ac a mainstream technology in short order.
Enterprise access points will begin appearing by midyear. One example is Cisco's previously announced 802.11ac plug-in module for its Aironet 3600 high-end access point. Cisco, and its rivals, have been upgrading their access points and controllers, adding memory, CPU power and other changes to handle the higher data rates as well as the anticipated higher demands that mobile Wi-Fi clients put on backend services such as encryption and authentication.
Vendors say they expect enterprises to phase in Gigabit Wi-Fi by adding 802.11ac radios first to high-density areas - with lots of clients or demanding applications or both. At some point, enterprises may have to upgrade WLAN controllers, wireline Ethernet backhaul, or switches (or some combination), and RADIUS and other backend network services.
For this infrastructure market, the radios will support two, three or four data streams. Chipmaker Marvell announced Dec. 3 the first 4x4 802.11ac system-on-chip, a companion to its client-focused 2x2 product. It's targeted at enterprise WLANs, carrier Wi-Fi networks, and video distribution applications.
One infrastructure segment to watch will be the carrier market. At least some mobile operators have been turning to and expanding use of Wi-Fi as a companion service for subscribers to use at least sometimes as an alternative to their cellular data plans. 802.11ac's faster data rates, capacity, improved signal quality and other features could trigger a rapid build-out of such services..."
