Role: non-profit, technical professional association

Main tasks: technical publishing, organizing conferences, standardization (esp. USA)

Members: 380,000 individuals in 150 countries

2.1 Working Groups

Aerospace, Broadcast, Communications, Electromagnetics, Information Technology, Instrumentation, Marine, Medical, Electrical Safety, Power Electronics, Power Energy, Quantities & Units, Reliability, Transport

All standardization takes place within IEEE-SA (Standards Association)

Most important from Mobile Internet perspective IEEE802 LAN/MAN Standards Committee which is under Information Technology




2.2 IEEE 802

Founded in 1980 and presented the standard for LANs 1 – 20 Mbps. The standard has been enlarged and the scope has grown to include MANs.

2.3 Wireless 802 Working Groups

2.3.1 802.11 Wireless Local Area Network

802.11 Work started in 1990 with wireless LANs published in 1997

• Data rates: 1 and 2 Mbps

• Media Access Control: Carrier Sense Multiple Access/Collision Avoidance

• Physical Layers: Direct Sequence Spread Spectrum and Frequency Hopping for 2.4 GHz and IR

802.11a added by Task Group a (TGa)

• Physical Layer: Orthogonal Frequency Division Multiplexing for 5 GHz enabling data rates to 54 Mbps

802.11b added by TGb

• data rates 5.5 and 11 Mbps by Complementary Code Keying for 2.4 GHz

802.11c and 802.11d specify other further enhancements of the 802.11




2.3.2 Enhancements to the Basic 802.11

2.4 Latest News on Wireless Working Groups

• The IEEE Communications Society has launched eight online tutorials recorded at three IEEE conferences in March. The 2.5- to 5-hour long sessions are the first in a catalog that is expected to expand to upwards of 50 conference tutorials. The most interesting from wireless point of view is:The Wireless Mobile Internet - Architecture, Protocols & ServicesAbbas Jamalipour, University of Sydney, AustraliaPart 1: Introduction to Mobile InternetPart 2: Advanced Technologies to Support Mobile InternetPart 3: Quality and Security for Mobile Internet

• The Institute of Electrical and Electronics Engineers (IEEE) has begun to develop a standard that will raise the effective throughput of wireless local area networks (WLAN) to at least 100 Mbps (megabits per second), which is more than triple the current maximum IEEE 802(R) WLAN speed of 30 Mbps.
