MOBILE TV NETWORK
Wireless communication systems use devices called transmitters to generate radio waves. A microphone or other device converts sound and data into impulses. The transmitters change the impulses into radio signals that can be sent across great distances. Radio receivers pick up these signals and turn this into its original form. Wireless communication has become a part of our daily life. It is used in our radios, televisions, mobile phones, remote controls and security systems. Wireless communications are rapidly growing segment of communications and have mind boggling applications for the future.
