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 Wireless Mobile Internet - Architecture, Protocols & Services 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.
