ABSTRACT
This chapter reviews many facets of emerging new wireless technologies that potentially have impacts on the corporate communications scenario. These technologies are poised to make fundamental changes in how business in transacted. Cellular phones, personal pagers, mobile data modems, wireless e-mail, personal digital assistants, and a plethora of other wireless devices and services have become indispensable productivity tools for managers on the move in corporate world. The spectacular success of the Advanced Mobile Phone Service (AMPS) stimulated demands for even higher capacities, better quality, and newer services. Wireless local area networks (LANs) typically operate over two different media: radio and infrared. Radio LANs use a radio frequency band to interconnect the elements of a LAN. Infrared LANs are an interesting alternative to radio LANs. Infrared technology is relatively simple and inexpensive. Video communications has been well known to be bandwidth-intensive, while wireless communications has been perennially in shortage of bandwidth.
