The RCS voice network is a
Project 25 Phase II 800 MHz
trunked, simulcast system. It currently is mixed Phase I and Phase II digital communications and digital encryption capable. Shortly, it will be full Phase II TDMA modulation.
The RCS data network is provided to the County of San Diego Sheriffs Department only, and uses the Motorola 700 MHz conventional High Performance Data system. It provides wireless data access to computerized applications, such as
