Packet radio

Packet radio is a form of digital data transmission used to link computers. The most common use of PKT is in amateur radio, to construct wireless computer networks. Its name is a reference to the use of packet switching between network nodes, which allows multiple virtual circuits to coexist on a single radio channel. Packet radio networks use the AX.25 data link layer protocol, derived from the X.25 protocol suite and adapted for amateur radio use.Note that while the term "packet radio" also was used for early version of mobile ad hoc networks, this technology has little in common with the description below.
