The Radio Telephone was the beginning of a mobile communication system
that has now advanced to where every piece of fire and rescue
apparatus has a communication system. All firefighters are also
assigned portable radio devices thus allowing all staff on an incident
scene to communicate with each other. Additionally, firefighters are
assigned a portable radio receiver to be carried while off duty. This
receiver is activated in the event of a major incident so that
firefighters are recalled quickly.
