Citizens band (CB) radio Two-way radio communication
Communication using the radio began with the two-way radio in the war, around the time of 1907. It was five years after that, that military use of the radio became more evident and available in order to make communication between ships.
Wireless communication is usually a form of radio communication. Radio communication uses a part of the electro-magnetic spectrum of radiation. Microwave ovens also use electro-magnetic radiation. If you have a radio that's operating close to the microwave range, or maybe an microwave oven that has a wide spectrum, then the oven can interfere with the radio.
Public service agencies don't use CB radio for official communication.
The original name for radio was "wireless telegraphy." This term referred to the transmission of telegraphic messages without the use of wires, utilizing electromagnetic waves instead. Over time, the term "radio" became more widely adopted to encompass all forms of radio communication, including voice, music, and data transmission. Today, "radio" broadly refers to all technologies that use electromagnetic waves for communication.
