You can say that wireless communication is communication that requires no wires! To put it more accurately, it is communication that takes 
place through the air, using radio waves or infrared light. There is no need for cables or telephone lines for wireless communication. Wireless communication systems use devices called transmitters to generate radio waves. A microphone or other device converts sound or other data into electrical impulses. The transmitters change the impulses into radio signals that can be sent across great distances. Radio receivers pick up these signals, and turn them back into the original sound or messages.Wireless communication has also become a part of our daily life. It is used in our radios, televisions, mobile phones, remote controls and security systems. Wireless communications are a rapidly growing segment of the communications industry, and have mind boggling applications for the future.
