• 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 isThe Wireless 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.
