Packet Switching

The process of routing and transferring data by means of addressed packets (very small pieces) so that a channel is occupied during the transmission of the packet only, and upon completion of the transmission the channel is made available for the transfer of other traffic.

In wireless, packet-switched data is generally faster than circuit-switched data. Packet-switched is also "always on", meaning a dedicated connection (circuit) does not have to first be established, which can take several seconds.
