Document Summary

Chapter 7: wireless, mobile computing, and mobile commerce. Wireless: describes telecommunications in which electromagnetic wave, rather that wire/cable is used to carry signal between communication devices. The ability to communicate anytime and anywhere provides organizations with a strategic advantage by increasing productivity and sped and improving customer service. Mobile computing: real time, wireless connection between a mobile device and other computing environment such as intranet or internet. Mobile commerce: transactions that re conducted in a wireless environment, especially via internet. Pervasive computing (ubiquitous computing): means the virtually every object has processing power with wireless or wired connections to a global network. Wireless application protocol (wap): is the standard that enables wireless devices to access web-based information and services. Microwave transmission: systems are widely used for high-volume, long-distance, lone-of-sight communication. It has high bandwidth, inexpensive, but must have unobstructed line of sight, and susceptible to environmental interference. Satellite transmission: systems that make use of communication satellites.
