Appendix 2 Glossary
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.
IEEE 802.15:
IEEE 802.15 is a working group of the IEEE 802 standards committee which specifies Wireless
Personal Area Network (WPAN) standards. It includes seven task groups. Task group one is based on
Bluetooth technology.
IEEE 802.16:
IEEE 802.16 is a series of Wireless Broadband standards authored by the Institute of Electrical
and Electronics Engineers (IEEE). Although the 802.16 family of standards is officially called Wireless MAN
in IEEE, it has been commercialized under the name “WiMAX” (from "Worldwide Interoperability for Microwave
Access") by the WiMAX Forum industry alliance.
802.16a:
802.16a, also known as WiMAX, extends throughput up to 70Mbit/s transmission rate within the
distance of 30 miles.
802.20:
Delivers 1Mbit/s throughput for wireless MAN (Metropolitan area network).
