EDACS:

A trunked radio system developed by General Electric and Ericsson, now owned by Harris Corporation, that provides coordinated communication between agencies.

Data Communication:

EDACS systems use control and working channels. The control channel transmits digital data to the field radios, while the working channels send voice and data. The D3100 modem plays a key role in enabling this digital data communication.

Frequency:

The D3100 is typically used in the 800 MHz band

Purpose:

EDACS systems, and by extension, the D3100 modem, are used by various agencies and organizations, including law enforcement, fire departments, and public utilities, for coordinating communication efforts.
