Misc System Information

Overview of Current Systems

(courtesy of the following document: "City & County of San Francisco, Request for Information, 800 MHz Public Safety Radio Replacement Project", July 30, 2014)[1]

"The primary public safety radio system for the City is the 800MHz Citywide Emergency Radio System (CERS). It is a mixed-mode, simulcast, 800MHz radio system, deployed at 8 radio sites throughout the City. The initial system was installed in 2000 and was a Motorola SmartZone 3.0 System, but had a major upgrade in 2009 to add a P25 Master Site Controller as well as a 700MHz Interoperability system. The system was designed to provide 95% in-building coverage throughout San Francisco... There are approximately 6700 Radios operating on the system, including portable handheld radios, mobile (in-vehicle) radios and fixed consolette radios."

"In addition to the public safety radio system, there is also a radio system dedicated to the City’s public service departments. The Public Service Emergency Radio System (PERS) is an analog 800MHz system deployed at 4 radio sites (which are a subset of the CERS radio sites). The system is simulcast, and was designed to provide 95% on-street coverage. The system was installed in 2007, and was integrated into the CERS Master Site Controller, as another simulcast cell."

SFPD Talkgroup Usage

A1 & A2: Southern and Tenderloin Stations
A3 & A4: Bayview and Mission Stations
A5 & A6: Central, Park and Northern Stations
A7 & A8: Richmond, Ingleside and Taraval Stations
A9 - A12: Spares, special events, etc
A11: Various units, incl. Traffic, Marine, etc
A13 & A14: car to station, etc. Not Dispatch monitored
A15: not used
A16: Tow Channel

Note that Central station was recently moved from A1 & A2 to A5 & A6 due to the high volume of radio traffic in the Southern and Tenderloin areas.

A Note on Multi-Selects

Multi-Select (temporary simulcast on multiple talkgroups) is constantly used on this system. SFPD dispatchers will multi-select both the mobile and portable talkgroups for their area (ex: PD-A1 and PD-A2) for BOLs and announcements, and dispatchers may also do "All Calls" by multi-selecting A1-A8 and A11. Fire dispatchers will multiselect SFFD Control A1, A2 and A3 for fire dispatches, plus EMS3 or EMS4 if city or private ambulances are dispatched as well.
