A to Z Decoder of Wireless Acronyms Please select a letter ABCDEFGHIJKLMNOPQRSTUVWXYZ 1
A 802.11 A: IEEE standard completed in 1999. Physical layer operates within the 5 GHz radio band and offers up to 12 non-overlapping channels (as opposed to three with 802.11b). It uses orthogonal frequency division multiplexing to offer maximum standardized data rate of 54 Mbps.
B 802.11 B: IEEE standard completed in 1999. Physical layer operating within the 2.4 GHz radio band. Offers only three non-overlapping channels. Uses complementary code keying to achieve maximum standardized rate 11 Mbps per channel, shared among all users.
C CDMA CF CF-End CFP CF-Poll CCI CCK CCP CCX CPM CSMA/CA CRC CTS CW Code Division Multiple Access Crest Factor Contention-Free End Contention-Free Period Contention-Free Poll Co-Channel Interference Continuous Shift Keying Compression Control Protocol Cisco Client eXtensions Continuous Phase Modulation Carrier Sense Multiple Access with Collision Avoidance Cyclic Redundancy Check Clear to Send Contention Window Back to top 1
D 802.11d: Standard completed in 2001. Radio emissions are subject to regulatory limits. 802.11 was written to comply with the regulatory limits in the US., Canada, and Europe. New regulators may specify different constraints for transmit power and allowed frequencies. Rather than revise the specification when new regulators issues rules, 802.11d allows an access point to “describe” allowed configurations to clients to make deployment easier.
E 802.11 e: Standard not yet completed; may be finished in 2003. Quality of Service (QoS) enhancements for 802.11 networks. QoS may be critical for new applications, such as voice over 802.11.
F 802.11f: Standard still under progress. It defines how clients work with access points, but does not define how networks of access points provide a single seamless network. Not relevant now because most large networks are single vendor; may be more important as multi-vendor become more common.
G 802.11 g: IEEE standard completed in 2003. Physical layer operates within the 2.4 GHz radio band. Uses OFDM and packet binary convolution coding to bring 54 Mbps speeds using the frequency band of 802.
H 802.11 h: Could be critical for Europe if accepted. European radio regulations for the 5 GHz band require products to have transmission power control (TPC) to limit RF energy and dynamic frequency selection to minimize interference with other systems.
I 802.11 i: Offers additional security for the 802.11. Builds on 802.11X to replace WEP.
J 802.11 J: Standard for Japan. Japan has authorized a slightly different frequency band (4.9 GHz – 5 GHz) for 802.11 a-like functionality.
