The Evolution of Untethered Communications
- Share to:
Extraordinary growth is evident in capabilities for “untethered” communications, the union of wireless and mobile technologies. An example is cellular telephones, which were virtually unheard of in 1980 and are now used by almost 200 million subscribers worldwide. The subscriber base for wireless communications services is growing 15 times faster than the subscriber base for wired services; by 2010 wireless and wired systems are expected to serve equal numbers of users. The vigorous public demand for wireless services is fueling intense industrial and government activity, including research and development (R&D) aimed at improving the quality and reducing costs of wireless technology, design of innovative systems and services, and implementation of new technical standards and policies. This dynamic environment is producing diverse wireless technologies and standards, in stark contrast to other areas of communications marked by a convergence toward uniformity. All this activity will bring the reality of the next century close to the vision of “anytime, anywhere” communications.
