802.11ac: IEEE 802.11ac is a wireless computer networking standard of
802.11, currently under development, providing high-throughput wireless local
area networks on the 5 GHz band. Theoretically, this specification will enable
multi-station WLAN throughput of at least 1 gigabit per second and a maximum
single link throughput of at least 500 megabits per second (500 Mbit/s).
802.11a: 802.11a is an amendment to the IEEE 802.11 specification that
added a higher data rate of up to 54 Mbit/s using the 5 GHz band.
802.11b: 802.11b, is an amendment to the IEEE 802.11 wireless networking
specification that extends throughput up to 11 Mbit/s using the same 2.4 GHz
band.
802.11e: 802.11e is an approved amendment to the IEEE 802.11 standard
that defines a set of Quality of Service enhancements for wireless LAN
applications through modifications to the Media Access Control (MAC) layer.
The standard is considered of critical importance for delay-sensitive
applications, such as Voice over Wireless LAN and streaming multimedia.
802.11g: 802.11g is an amendment to the IEEE 802.11 specification that
extended throughput to up to 54 Mbit/s using the same 2.4 GHz band as
802.11b.
802.11h: 802.11h, refers to the amendment added to the IEEE 802.11
standard for Spectrum and Transmit Power Management Extensions. It solves
problems like interference with satellites and radar using the same 5 GHz
frequency band. It was originally designed to address European regulations
but is now applicable in many other countries.
802.11i: 802.11i, implemented as WPA2, is an amendment to the original
IEEE 802.11.
802.11j: 802.11j is an amendment to the IEEE 802.11 standard designed
specially for Japanese market.
802.11n: 802.11n is an amendment to the IEEE 802.11 standard, which
improves network throughput over the two previous standards—802.11a and
802.11g—with a significant increase in the maximum net data rate. 802.11n
standardized support for multiple-input multiple-output and frame aggregation,
and security improvements, among other features.
