IEEE Wi-Fi to top 1Gbps

IEEE Wi-Fi to top 1Gbps

IEEE has recently initiated the first step in a vote on a major upgrade of the Wi-Fi standards within two years. 802.11a standard should update 802.11ac use 80MHz and 160MHz channels that provide much more bandwidth than today.

Combined with a 10 percent increase in the efficiency of the actual shift frequency modulation rate should be increased to improve the theoretical transfer rate of up to 1 Gbps, or more than three times the 300Mbps 802.11n achieves for now.

Since the technology is still in the phase of the project and only began to seriously debate on 10 November, specifications can change. However, the technology used as a draft standard in late 2011 and should be fully approved in December 2012.

Interim measures also underway for the ratification of the 802.11n standard, earlier this year and should provide three or even four MIMO (multiple input, multiple output) data flow to accelerate the theoretical speed of 300 Mbps in 802.11n two lines today at 450Mbps in three watercourse or 600 Mbps, with four.

Current client and router hardware, such as Intel 5300 and autumn 2009 Apple Airport devices, and supports the three streams, and simply need to connect to devices that can send and receive three streams of itself. Nobody knows how many Macs, if necessary, and to support the three streams.
