CELLULAR COMMUNICATION TECHNOLOGY
ABSTRACT
The mobile communication devices consist of hand held phones, car phones, notebook computers, personal digital assistants, pen-based computers, palm-top computers, and portable data collection devices. Since only two percent of the cellular traffic is data, the most popular mobile units are cellular telephones (Gareiss, 1995). When these mobile units communicate to the network, they must register with the system by subscribing to a carrier service. Most carrier services have arrangements with other providers allowing users to roam. Roaming occurs when the mobile unit is outside the coverage of their cellular service provider and an alternative cellular provider places the call.
Cellular technology extends the bounds of a corporation's existing telecommunications infrastructure by connecting mobile units to the public network operated by the local exchange or long distance carriers.
