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

The technical concept of a radiotelephone extends beyond simple point-to-point transceivers, and also includes radios that can interface with all the land telephone system. On this arrangement, a base receiver is associated with a standard phone. Voice signals sent from your mobile radio are acquired from the base station and forwarded through the phone lines. An individual operator may be used to connect calls, or even an automated tone-controlled system works extremely well. These kinds of radiotelephone installations were not unusual before cellular phones became prominent.

Cellular phones have been radiotelephones, although they are hardly ever called with that name today. Each “cell” or section of phone coverage posesses a radio station which is linked to the traditional phone grid. A handheld mobile phone unit includes a short range radio transceiver. Early cellular phone radiotelephone conversations were sent using a standard radio signal and could be found by any receiver on the proper frequency. Modern calls are encrypted to avoid eavesdropping.

Despite the popularity of mobile phones, many people still use more standard radiotelephones for professional and hobby communication. Businesses often employ mobile voice radios to dicuss in areas which might be outside cell coverage, such as remote construction sites. Amateur radio experimenters use handheld and vehicle radiotelephones to get in touch along with other enthusiasts, and have use of private radio repeaters that are exactly like the mainstream mobile phone networks.
