Wireless networks are commonplace today and the latest standard, 802.11n, provides transmission speeds up to 300Mbps. But within two years, we can see an update of WiFi technology in the new 802.11ac protocol can provide transmission speeds up to 1Gbps, more than three times as fast as current wireless networks. This by sending data over the 5GHz band and up to four times as wide channels.
Today's 802.11n standard support channels at 20MHz respectively. 40MHz but 802.11ac talk about channels as wide as 80MHz or even 160MHz. Which makes it possible to increase the data flow considerably?
But even before the IEEE solid rather than the new protocol is not expected to occur until 2012 at the earliest we will see performance improvements of 802.11n technology. By allowing manufacturers to use multiple transmitters and up to three or four MIMO data streams can reach speeds of 450 to 600Mbps.
Already today there is support for three MIMO data streams in particular, Apple's latest Airport Devices and Intel 5300 chips, so the only thing needed is support for the technology in devices that make use of these circuits.
