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.
