  14. 2 The Institute of Electrical and Electronics Engineers (IEEE) 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 Anna Hosia & Johnny Biström

  15. 2 The Institute of Electrical and Electronics Engineers (IEEE) 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. 2.2.1 Organization Working Groups (WG), Technical Advisory Groups, Sponsor Executive Committee Active Working Groups: 802.1 802.3 802.11 802.15 802.16 802.17 802.18 Wireless Broad- Resilient High CSMA Wireless Personal band Radio Packet Level / Area Wireless LAN Regulatory Ring Interface CD Network Access MAN = Metropolitan Area Network, CSMA/CD = Carrier Sense Multiple Access/Collision Avoidance Anna Hosia & Johnny Biström

  16. 2 The Institute of Electrical and Electronics Engineers (IEEE) 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 Anna Hosia & Johnny Biström

  20. 2 The Institute of Electrical and Electronics Engineers (IEEE) 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.
