This little essentiality mobile personal communication device has transformed American the face of society. No long confined to the length of a cord, telephones are now able to go just about everywhere.

Wireless communication as we know it today had it began in radio; actually a cellular telephone is a type of two-way radio. It wasn’t until 1947 when AT&T propositioned the Federal Communications Committee (FCC) to allocate a radio frequencies did a mobile network become feasible. The research began with crude car telephone within the Chicago area. Despite the small number of radio frequencies set aside the research showed so much promise and potential However when one the enormous commercial opportunity was recognized AT&T could not maintain there monopoly on the market.

How cellular telephones work is really very simple, they use low-energy FM radio waves to transmit voice to the nearest antenna site connected with the local telephone network. The call goes through either a regular telephone line, or by radio signal to another cell telephone, depending on the service. Wireless technology uses individual radio frequencies over and over by dividing service areas into different geographic zones. These zones are called "cells." Cells can be as small as Madison Square Garden or as large as New York City. Typically, there are more cells in cities than in rural areas simply because there are more people trying to make calls in urban areas. Each has its own radio transmitter and receiver antenna linked to Mobile Telephone Switching Offices (MTSOs).

...ast will continue and even increase in the future. The wireless industry is evolving from an industry that provided primarily voice communications services to one that increasingly works as a network providing computer functionality, such as Internet access. New third-generation ("3G") products will provide similar, much improved, services to remote users. Anticipated uses for new technologies include enhanced voice and high-speed data links to office computers, the ability to send and receive faxes, high-speed Internet connectivity, video transmission and video conferencing. Wireless companies such as Verizion plan to expand wireless networks into new markets and rural areas with the goal of uninterrupted service throughout North America. The current expansion in networks has distributed the job growth from metropolitan areas to some of the most rural parts of the country. Continued investment in network upgrades and expansion will continue to have a positive effect on local economies throughout the country. Mobile data services available over the new wireless digital networks will permit increased expansion of Internet access into urban, rural and suburban communities,
