About
the Subject :
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.
Topics
