WiFi will reach 1Gbps speed in 2012

After the IEEE 802.11n Wi-Fi standard (Institute of Electrical and Electronics Engineers) approved on September 11 after 7 years of development, IEEE recently started steps First vote on improving Wi-Fi standards implemented in two years .

The new 802.11ac standard will be an older 802.11a-based upgrade to use 80MHz channels or even 160MHz to provide more bandwidth than today. With about 10% increase in actual frequency modulation efficiency, acceleration will improve theoretical communication speeds up to 1Gbps (gigabit per second), more than three times the 300Mbps speed that 802.11 standard n achieved.

Since this technology has not yet entered the draft stage and has just begun to be seriously discussed on November 10, its specifications are likely to change. However, this technology will be able to be used as a draft standard by the end of 2011 and will be officially approved in December 2012.

After approving 802.11n in September this year, the standard can raise three or even four data streams of MIMO (multiple in, multiple out) to accelerate the theoretical speed of 802.11n from 300Mbps on two existing threads. up to 450Mbps with 3 streams or 600Mbps with 4 streams. Some hardware and routers now support up to 3 data streams and only need to be connected to devices that support sending and receiving 3 similar streams. One of them is the Intel 5300 processor and Apple's Airport Extreme devices in the fall 2009 release that has been supported for up to 3 data streams. However, it is not known how many Macs have supported 3 data streams.
