Citizens Band Radio (CB radio) refers to a type of two-way radio system widely used for communication between individuals in short-range distances, typically up to several miles. It operates within the Citizens Band Radio Service (CBRS), which is a range of radio frequencies assigned for public use by regulatory authorities.
CB radios are often found in vehicles, such as cars, trucks, and recreational vehicles (RVs), as well as in fixed locations like homes and offices. They are designed to facilitate simple and immediate communication among users, allowing for conversations on a specified channel.
The term "citizens band" emphasizes that CB radios are intended for public use, enabling private citizens to communicate with each other. CB radios allow for both transmitting and receiving messages, employing amplitude modulation (AM) or Single Sideband (SSB) modulation techniques. This allows voices to be transmitted over the radio waves and heard by others within the designated range on the same channel.
CB radios are commonly used for a variety of purposes, including emergency communication, trucking and transportation coordination, off-roading activities, and social interaction among individuals with similar interests. Despite the rise of alternative communication technologies like cell phones, CB radios continue to be popular in certain communities, providing a reliable, real-time means of communication that does not rely on cellular network coverage.
Overall, citizens band radios serve as a convenient and accessible means of communication, allowing individuals within a close distance range to connect and exchange information or engage in casual conversations.
