Wireless
communication is the transfer of information between two or more
points that are not connected by an electrical conductor.
The
most common wireless technologies use radio. With radio waves
distances can be short, such as a few meters for television
or as far as thousands or even millions of kilometers for deep-space radio
communications. It encompasses various types of fixed, mobile, and portable
applications, including two-way radios, cellular
telephones, personal digital assistants (PDAs), and wireless
networking. Other examples of applications of radio wireless
technology include GPS units, garage door openers, wireless computer mice,
keyboards and headsets,
headphones,
radio
receivers, satellite television, broadcast television and cordless telephones.
Somewhat
less common methods of achieving wireless communications include the use of
other electromagnetic wireless technologies, such as
light, magnetic, or electric fields or the use of sound.
