Summary

  • The Web is going wireless. By 2003, more people will access the Internet via mobile phones than through computers.

  • Most existing mobile phone systems are 2G. New 3G terminals will support higher-speed data services. Further in the future, 4G may enable true mobile broadband.

  • Short-range wireless LANs and longer range cellular systems are fundamentally different, but can be used for similar applications. They are both competing and complementary.
