IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication.

What is the difference between 802.11 a 802.11 b 802.11 g and 802.11 n?

In basic terms, 802.11n is faster than 802.11g, which itself is faster than the earlier 802.11b. ... Among its key innovations, 802.11n adds technology called multiple-input multiple-output (MIMO), a signal processing and smart antenna technique for transmitting multiple data streams through multiple antennas.

Which 802.11 mode is fastest?

If you're looking for faster Wi-Fi performance, you want 802.11ac — it's that simple. In essence, 802.11ac is a supercharged version of 802.11n. 802.11ac is dozens of times faster, and delivers speeds ranging from 433 Mbps (megabits per second) up to several gigabits per second.

Which is better 802.11 ac or 802.11 N?

So AC WiFi is much faster, but its peak speeds are not really the selling point. It's speeds at long range are. ... In fact 802.11ac uses the 5GHz band while 802.11n uses 5GHz and 2.4GHz. Higher bands are faster but lower bands travel further.

What is an example of an IEEE standard?

An Example of an IEEE standard is IEEE 802.11 which refers to the rules/guidelines that define communication for wireless LANs. ... ITU-T is a part of a division of the INTERNATIONAL TELECOMMUNICATION UNION, where by it coordinates standards for telecommunications.
