    A radiotelephone is any device utilized to transmit voice transmissions over radio waves. A wide variety of devices fall under this definition. Many radiotelephones can relay messages through traditional land phone lines, while some are employed mainly for mobile-to-mobile wireless transmissions. Many modern devices like cell phones are technically viewed as radiotelephones.

    The most basic kind of radiotelephone is an easy transceiver that sends voice signals to a new station. The radios employed by police cars are examples of standard radiotelephones. Ships, aircraft, and military units also commonly use radiotelephones for communication, because they often operate in situations where other voice transmission methods are certainly not available.

    The technical concept of a radiotelephone extends beyond simple point-to-point transceivers, plus includes radios that will interface with all the land telephone system. Within this arrangement, a base receiver is associated with an average phone. Voice signals sent from your mobile radio are found through the base station and forwarded from the phone lines. A person’s operator is known to connect calls, or an automated tone-controlled system can be employed. These kind of radiotelephone installations were not unheard of before mobile devices became prominent.

    Cellular phones have been radiotelephones, although they are rarely called with this name today. Each “cell” or area of phone coverage posesses a radio station that’s for this traditional phone grid. A handheld mobile phone unit contains a short range radio transceiver. Early cellphone radiotelephone conversations were sent with a standard radio signal and could be found by receiver around the proper frequency. Modern calls are encrypted to stop eavesdropping.

    Regardless of the popularity of cellular phones, a lot of people still use easier radiotelephones for professional and hobby communication. Businesses often employ mobile voice radios to talk in areas which are outside cell coverage, for example remote construction sites. Amateur radio experimenters use handheld and vehicle radiotelephones to connect to enthusiasts, and possess access to private radio repeaters which are like the mainstream cellular phone networks.
