IEEE 802.11ac, has been defined with the promise of delivering significant increases in bandwidth while improving the overall reliability of a wireless connection. The ultimate goal of this standard is to produce a single-radio design with wireless data rates in excess of 1 Gbps.
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).”
The wider 802.11ac channels (80 and 160 MHz) support higher data rates, but, when implemented, reduce the number of available no overlapping channels. This does pose a problem for vendors like Cisco, Aruba, HP and UBNT that use multi channel RF design versus Meru Networks’s Virtualized Wireless Network architecture, which has been built to mitigate co-channel interference and fully leverage 802.11ac’s higher throughput and capacity. Meru is going to be the winner for the new IEEE 802.11ac standard whether an enterprise deploys a single-channel or layered-channel solution, Meru’s architecture will allow the user community to access the most bandwidth in the most reliable way from an 802.11ac network.
You really think that with their close relations to Qualcom Atheros and the bulf of their current customers using 5Ghz Airmax prodcuts that Ubiquiti is not working on 802.11ac products. I don't think so.... 802.11ac is not ready for prime time yet, but I'd bet more than a buck that we will see a high power, outdoor, 802.11ac device in the Rocket chassis, as well as variations of the UniFi product. This would be a natural for UBNT, and readily accepted by the WISPs that comprise their customer base.
