The next step in the evolution of WLAN- 802.11ac
Nowadays almost all mobile devices such as smartphones, tablets and notebooks are using wireless communication. Buffalo Technology, leaders in innovation, were the first manufacturers to introduce a router and the first wireless bridge incorporating the new 11ac technology to the global market.
To ensure the compatibility in a network, several standards were released by the IEEE working group. IEEE 802.11 is the IEEE working group developing Wireless Local Area Network specifications. The group began work in the late 1990s and since then has created several successful standards/amendments including 802.11a, b and g. WLAN is now everywhere, with one or more of these WLAN technologies included as standard capabilities on most laptops and most smartphones. The IEEE 802.11 group has continued to build and improve on the earlier a/b and g with the official approval of 802.11n in 2009 and other enhancements such as 802.11w, 11k, etc.
Late in 2008, two new task groups, TGad for the 802.11ad amendment and TGac for the 802.11ac amendment, were started with the goal of significantly improving the data throughput of 802.11 so that performance of a wireless network can be equivalent to a wired network. 802.11ad will use very wide bandwidths in the 60GHz band and 802.11ac will use frequencies in the 5GHz. Both amendments were scheduled for completion at the end of 2012. The standard is expected to be released in 2013.
What is new?
With the implementation of new technologies in the wireless standard the first time Gigabit speed in WLAN is in reach. The channel bandwidth is 80 MHz at minimum instead of 40 MHz as it is in the 802.11n standard. Multi-MIMO ensures that more clients can be connected with a higher speed and better signal quality. These as the more important combined with other features and existing technologies are resulting in a PHY rate of more than 1Gb/s.
Prepared for now and the future
Along with greatly enhanced speeds, 802.11ac features improved reliability and range and it is backward compatible with 802.11n to support your most recent wireless devices. Whether you're streaming media from movie portals or gaming online with your Xbox® or PS3™, you'll experience faster, uninterrupted
