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 & Services

Abbas Jamalipour, University of Sydney, Australia

Part 1: Introduction to Mobile Internet

Part 2: Advanced Technologies to Support Mobile Internet

Part 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.
