The LAFD has two different wireless communications systems. The first is the “voice” radio system and the second is the “data” radio system. The voice radio system is the system commonly recognized because it is the system in which we receive dispatches and talk from unit to unit every day. The voice radio system is an “_________” system .________ means that the system is not a trunked system and utilizes more then one repeater, or send and receive sites to receive and transmit radio messages.
The data system carries our Mobile Display Terminal (MDT) communications. It is not recognized as a separate system because the user interface is by pushing a button on the MDT. Because our interaction is limited, it is commonly not thought of as a radio system. However, they are separate and distinctly different systems.
