Regional Communications System
Vision
 To provide seamless wireless communications for public
safety/service agencies serving 3,000,000 people in San
Diego County and Imperial County.
 To provide RCS users with wireless interoperability with
other local systems.
 INTEROPERABILITY means law, fire, EMS and public service can talk
readily with each other to coordinate life saving responses.
 No one should lose their life or property because public safety
personnel cannot communicate with each other.

Regional Communications System
Wireless Design Goals
 The RCS design goals:
 Improve compatibility with existing 800 MHz systems.
 Provide highly reliable wireless voice and data
networks.
 Provide minimum 95% wireless coverage of the
roadway network.
 Provide wireless data access for computer
applications, including:
 Automatic Vehicle Location (AVL)
 Law enforcement databases
 Computerized dispatch operations

Shared Governance
 Partners approved a “Participating Agency Agreement”.
 San Diego County Board of Supervisors authorized RCS Board of
Directors to administer system.
 Member agency representatives select the
RCS Board of Directors.
 13 members: Chief/Department Head level fire, law, public service,
representing their peer agencies.
 No politicians on Board of Directors.
 San Diego Sheriff’s Department Wireless Services Unit
manages day-to-day RCS operations.
 Board of Directors provides RCS administrative direction and
oversight.

Regional Communications System
Implementation - Operation
 Agencies began using the RCS in May 1998.
 Over 18,000 radios are currently on the voice system.
 Voice and data coverage acceptance tests - 97%.
 Management Assessment Study (Deloitte & Touche)
of the RCS validated the system design, goals and
project management.
