Wireless (networking): The ability to access the Internet without a physical network connection. Devices such as cell phones and PDAs that allow you to send and receive email use a wireless Internet connection based on a protocol called WAP (Wireless Application Protocol). At this point, web sites that contain wireless Internet content are limited, but will multiply as the use of devices relying on WAP increases.
