Packet radio is a form of packet switching technology used to transmit digital data via radio or wireless communications links. It uses the same concepts of data transmission via Datagram that are fundamental to communications via the Internet, as opposed to the older techniques used by dedicated or switched circuits.
Early Networks. In 1973, engineers began to look at ways to connect ARPANET to the packet radio network (PRNET). A packet radio network connects computers through radio transmitters and receivers. Instead of sending data across phone lines, the computers use radio waves.
