The term “walkie-talkie” itself is believed to have originated during World War II. The name was coined to describe the portable radio devices that enabled soldiers to communicate while on the move, allowing them to “walk” and “talk” simultaneously.
After the war, walkie-talkies found numerous applications in various industries, including public safety, law enforcement, and commercial sectors. They became widely adopted by police departments, security personnel, outdoor enthusiasts, and professionals requiring instant short-range communication.
Over time, walkie-talkies evolved to incorporate advanced features and technologies. Analog systems were gradually replaced by digital models, offering improved sound quality, longer battery life, encryption capabilities, and additional functionalities like text messaging and GPS integration.
CB radios operate on the principle of amplitude modulation (AM). They utilize the electromagnetic spectrum to transmit and receive signals. CB radios operate on specific frequencies within the 27 MHz band, allowing users to communicate over short distances. The voice messages are modulated onto the carrier wave by varying the amplitude, and the receiver demodulates the signal to reproduce the original voice message. CB radios typically have a fixed set of 40 channels, each with a designated frequency, allowing multiple users to communicate simultaneously.
