State Radio Systems

California Emergency Services Radio System (CESRS)

CESRS is the network Cal OES uses for direction and control/mutual aid coordination. It connects Cal OES Regions, field staff, and many Operational Area Emergency Operations Centers (EOCs) via two-way radios. CESRS is also used in direct mode (CESRSD) as the "travel channel" for CAL FIRE strike teams travelling to and from mutual aid incidents.
