WIRELESS

Wireless communication is the transfer of information over a distance without the use of electrical conductors or " wires". The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). When the contaxt is clear, the term is often shortened to "wireless". Wireless communication is generally considered to be a branch of telecommunications.
Handles wireless radios such as this Maritime VHF radio trasceiver use electromagnetic waves to implement a form of wireless communication of technology.The term "wireless" has become a generic and all-encompassing word used to describe communications in which electromagnetic waves or RF (rather than some form of wire) carry a signal over part the entire communication path.

1. Radio frequency communication
2. Microwave communication
3. Infrared (IR)
Appliance may involve point to point communication, point to point mutipoint communication, broadcasting, cellular networks and other wireless networks.
