Describe Wireless Communication Methods for Laptops and Portable Devices

Wireless devices give people the freedom to work, learn, play, and communicate wherever they want. People using wireless-capable devices do not need to be tied to a physical location to send and receive voice, video, and data communications. As a result, wireless facilities, such as Internet cafes, are opening in many countries. College campuses use wireless networks to allow students to sign up for classes, watch lectures, and submit assignments in areas where physical connections to the network are unavailable. This trend toward wireless communications will continue to grow as more people use wireless devices.
