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 second-generation, or 2G. Third-generation terminals will support high-speed data services.

• Mobile phones emit microwave radiation, which is dangerous, but they keep within strict guidelines, minimizing the risk to people.

• Hands-free headsets probably help to protect users from radiation.
