Wireless technology is the method of delivering data from one point to another without using physical wires, and includes radio, cellular, infrared, and satellite.

The discovery of electromagnetism, induction, and conduction provided the basis for developing communication techniques that manipulated the flow of electric current through the mediums of air and water.

Guglielmo Marconi was the first person to prove that electricity traveled in waves through the air, when he was able to transmit a message beyond the horizon line.

The limitations on frequency usage that hindered demand for mobile telephone service were relieved by the development of the geographically structured cellular system.

Vertical markets are beginning to realize the use of wireless networks. Wireless technology can be used for business travelers needing airport and hotel access, gaming and video, for delivery services, public safety, finance, retail, and monitoring.

Horizontal applications for wireless include new technology for messaging services, mapping (GPS) and location-based tracking systems, and Internet browsing.

The chapters of this book are to be used as building blocks. The early chapters present information on wireless LAN technologies, network protocols, emerging wireless technology, and network design concepts. The last four chapters contain case studies that build on that information and...
