What is a radiotelefone?
Radiotelefon is any device used to send voice transmissions via radio waves. This definition includes a wide range of devices. Many radiotelephones can transmit messages via traditional ground lines, while others are used exclusively for wireless mobile transfers to mobiles. Many modern devices, such as mobile phones, are technically classified as radiotelephones.
The most basic type of radiotelephone is a simple transmitter that sends voice signals to another station. Radio used by police cars are examples of standard radiotelephones. Ships, aircraft and military units also commonly use radiotelephones for communication because they often work in situations where other methods of voice transmission are available.
In the United States, the Federal Commission (FCC) since the 1930s was regulated by the signals of radio -phones. According to the FCC regulations, the radiotelefon is different from the telegraph or morse code of the transmission because it is specIlyally intended for wireless speech transmission. Although technology has changed significantly since the first days of voice communication, FCC continues to offer a radiothene operator license. This certification is required for anyone who uses a high -performance boat or aircraft.
Thetechnical definition of the radio-phone exceeds simple transceivers Point-to-Point and also includes radios that can connect to the ground phone system. In this arrangement, the basic receiver is connected to a normal phone. Voice signals sent from the mobile radio are picked up by a basic station and handed over by telephone lines. The human operator can be used to connect calls or use an automated tone controlled system. These types of radiothelephone installations were quite common than mobile phones became significant.
Mobile phones are actually radioteletelefony, although this name is rarely called todayo. Each “cell” or telephone coverage area contains a radio station that is connected to a traditional telephone grid. The pocket mobile unit contains a short range radio transceiver. The conversation of the radiotelefone with a mobile phone was sent by a standard radio signal and could pick up any receiver at the right frequency. Modern calls are encrypted to prevent eavesdropping.
Despite the popularity of mobile phones, many people still use simpler radiotelephones for professional and hobby. Businesses often use mobile voice radios to speak in areas that are out of cell coverage, such as remote construction sites. Amateur radio experiments use the manual and vehicle radiotelefony to connect with other enthusiasts and have access to private radio repetitions that are similar to conventional mobile phone networks.
