Wireless technology

Overview
Spectrum bandwidth is a finite resource. Commercial wireless communications currently rely on bandwidth within a narrow range &mdash; a "sweet spot." Wireless communications is constrained by the limited amount of useful bandwidth available. This constraint is both specific, in the inherent finiteness of spectrum, and relative, in comparison to the amount of spectrum available for commercial use in other countries.

Wireless communications services have grown significantly worldwide, and explosively in some countries. As wireless technologies evolve, they are converging with Internet technologies. Third-generation and future developments in wireless technology will be able to support services for business and consumer markets, such as: enhanced Internet links, mobile intranet/extranet, mobile commerce (m-commerce) &mdash; including the ability to make payments &mdash; "always on" capabilities, and high-quality streaming video.

Some m-commerce services use location-finder technology. In the United States, location-finder technology is also being introduced through the nationwide Enhance 911 (E911) program.
