802.11 standard 802.11, or IEEE 802.11, is a type of radio technology used for wireless local area
networks (WLANs). It is a standard that has been developed by the IEEE (Institute of Electrical and
Electronic Engineers) at http://standards.ieee.org . The IEEE is an international organization that
develops standards for hundreds of electronic and electrical technologies. The organization uses a
series of numbers, like the Dewey Decimal system in libraries, to differentiate between the various
technology families. The 802 subgroup (of the IEEE) develops standards for local and wide area
networks with the 802.11 section reviewing and creating standards for wireless local area networks.
Wi-Fi, 802.11, is composed of several standards operating in different radio frequencies:
802.11b is a standard for wireless LANs operating in the 2.4 GHz spectrum with a
bandwidth of 11 Mbps.
802.11a is a different standard for wireless LANs, and pertains to systems operating in
the 5 GHz frequency range with a bandwidth of 54 Mbps.
Another standard, 802.11g, is for WLANS operating in the 2.4 GHz frequency but with a
bandwidth of 54 Mbps.
Glossary of Terms
Wireless Terminology
802.11b International standard for wireless networking that operates in the 2.4 GHz
frequency range (2.4 GHz to 2.4835 GHz) and provides a throughput of up to
11 Mbps. This is a very commonly used frequency. Microwave ovens, cordless
phones, medical and scientific equipment, as well as Bluetooth
®
devices, all
work within the 2.4 GHz frequency band.
802.11g Similar to 802.11b, but this standard provides a throughput of up to 54 Mbps. It
also operates in the 2.4 GHz frequency band but uses a different radio
technology in order to boost overall bandwidth.
AES (Advanced Encryption
Standard) A chip-based security, has been developed to ensure the highest degree of
security and authenticity for digital information, wherever and however
communicated or stored, while making more efficient use of hardware and/or
software than previous encryption standards. It is also included in IEEE 802.11i
standard. Compared with AES, TKIP is a temporary protocol for replacing WEP
security until manufacturers implement AES at the hardware level.
DHCP Dynamic Host Configuration Protocol. This protocol automatically configures
the TCP/IP settings of every computer on your home network.
Encryption key An alphanumeric (letters and/or numbers) series that enables data to be
encrypted and then decrypted so it can be safely shared among members of a
network. WEP uses an encryption key that automatically encrypts outgoing
wireless data. On the receiving side, the same encryption key enables the
computer to automatically decrypt the information so it can be read.
