CALIFORNIA HIGHWAY PATROL ENHANCED RADIO SYSTEM This section is a discussion of the various aspects of the California Highway Patrol Enhanced Radio System (CHPERS) project. It is assumed that the reader has a basic understanding of the existing CHP radio system. 13. Simulcast Support in Existing Locations 13.1. Current simulcast areas are the Los Angeles Communications Center (LACC), Golden Gate Communications Center (GGCC), Border Communications Center (CC) and Inland CC. In a simulcast radio system, all transmitters on the same frequency are keyed at the same time (i.e., simultaneous transmission of the same information). 13.1.1. The GGCC simulcast radio system will not be included as part of the CHPERS project (except as noted below), since there is a current CHP project, which is unrelated to the CHPERS project, to replace the simulcast control equipment and remote site base stations used by the GGCC simulcast radio system. 13.2. Remote Site Simulcast Control Equipment. The CHPERS project will replace existing remote site simulcast control equipment because the equipment is beyond its amortized life expectancy and replacement parts are costly and increasingly hard to obtain. 13.2.1. Remote site simulcast control equipment is the equipment (located at remote sites) required to control and align a radio transceiver in order for it to operate as a simulcast transmitter. 13.2.2. Remote site simulcast control equipment will be replaced for Border CC and Inland CC under the CHPERS project. 13.2.3. Remote site simulcast control equipment associated with LACC and GGCC have recently been or will soon be replaced as part of other approved CHP projects unrelated to CHPERS; therefore, the CHPERS project will only purchase replacement remote site simulcast control equipment for GGCC and LACC for installation at a later date (after the Prepared by OCIO, Public Safety Communications Division, Office of Public Safety Communications Services System Enhancements Rev 04.3r4.doc Last Save Date: 6/1/2009 3:29 PM Page 25 of 86 completion of the CHPERS project) as part of normal equipment replacement. 13.2.4. Replacement of the existing remote site simulcast control equipment will involve the following steps: 13.2.4.1. Temporarily relocating the equipment in the rack to make room for the new equipment. 13.2.4.2. 13.2.4.3. 13.2.4.4. Installing and testing the new equipment. Aligning and phasing the transmitters. Disconnecting the old equipment and connecting the new equipment when the new system is ready for cutover. 13.2.4.5. 13.3. Completely removing the old equipment. Remote Site Base Station Equipment (Simulcast). The CHPERS project will replace remote site base station equipment (simulcast lowband base station racks and associated radio equipment) because the equipment is beyond its amortized life expectancy and replacement parts are costly and increasingly hard to obtain. 13.3.1. Remote site base station equipment is generally comprised of an equipment rack which contains a radio transceiver(s) and its ancillary miscellaneous radio equipment, a Global Positioning Satellite (GPS) reference receiver(s) and miscellaneous associated equipment. 13.3.2. Remote site base station equipment will be replaced for Border CC and Inland CC under the CHPERS project. 13.3.3. Remote site base station equipment associated with LACC has recently been replaced. Remote site base station equipment associated with GGCC will soon be replaced as part of an approved CHP project unrelated to CHPERS. 13.3.3.1. LACC’s recently replaced base stations will not meet FCC licensing requirements for the new CHPERS frequency assignments, the CHPERS project will replace these base stations with FCC compliant lowband base stations. The base stations that are to be replaced are fairly new; therefore, CHP Prepared by OCIO, Public Safety Communications Division, Office of Public Safety Communications Services System Enhancements Rev 04.3r4.doc Last Save Date: 6/1/2009 3:29 PM Page 26 of 86 will keep and use these base stations as back-up parts for other radios currently operational. 13.3.3.2. GGCC’s current project’s replacement base stations will also not meet FCC licensing requirements for the new CHPERS frequency assignments, the CHPERS project will provide newer FCC compliant lowband base stations for installation under the current GGCC project. The current GGCC project’s original replacement base stations are fairly new; therefore, CHP will keep and use these base stations as back-up parts for other radios currently operational. The CHPERS project will also purchase replacement RF equipment for GGCC for installation at a later date (after the completion of the CHPERS project) as part of normal equipment replacement 13.3.4. Replacement of the existing simulcast base station equipment racks will involve the following steps: 13.3.4.1. Temporarily relocating the existing rack to make room for the new rack. 13.3.4.2. 13.3.4.3. 13.3.4.4. Installing and testing the new rack. Aligning and phasing the transmitters. Disconnecting the old rack and connecting the new rack when the new system is ready for cutover. 13.3.4.5. 13.4. Completely removing the old rack. Dispatch Simulcast Control Equipment. CHPERS will replace the existing dispatch simulcast control equipment at Border CC and Inland CC. The existing dispatch simulcast control equipment at GGCC and LACC will not be replaced since that equipment has recently been or will soon be replaced; therefore, the CHPERS project will only purchase replacement dispatch simulcast control equipment for GGCC and LACC for installation at a later date (after the completion of the CHPERS project) as part of normal equipment replacement. 13.4.1. Replacement of the dispatch simulcast control equipment at Border CC and Inland CC is necessary due to the age and obsolescence of the Prepared by OCIO, Public Safety Communications Division, Office of Public Safety Communications Services System Enhancements Rev 04.3r4.doc Last Save Date: 6/1/2009 3:29 PM Page 27 of 86 existing equipment. Border CC and Inland CC are currently using simulcast control equipment that utilizes 15 year old technology. 13.4.2. Replacement of the dispatch simulcast control equipment at these communications centers will involve the following steps: 13.4.2.1. Temporarily relocating the existing dispatch simulcast control equipment to make room for the new dispatch simulcast control equipment. 13.4.2.2. Installing and testing the new dispatch simulcast control equipment. 13.4.2.3. 13.4.2.4. Aligning and phasing the system. Disconnecting the old dispatch simulcast control equipment and connecting the new dispatch simulcast control equipment when the new system is ready for cutover. 13.4.2.5. Completely removing the old dispatch simulcast control equipment. 13.5. As required, replace antennas (that are more than 5 years old), heliax cables, cavity filters and install additional cavity filters at all simulcast remote sites to facilitate duplex operation. 13.5.1. Replacement of older antennas is necessary to ensure maximum RF coverage and performance. 13.5.2. 13.5.3. Replacement of heliax cables is necessary to reduce RF signal loss. The CHPERS project includes the replacement of existing cavities and, as required, the installation of additional cavities to enhance the radio system. Cavities are used to filter out unwanted radio signals which can cause interference to the desired receive and transmit signals, as well as allows several base station transmitters to be coupled to a shared transmit antenna. 13.6. The existing voting equipment (which is currently part of the Avtec dispatch consoles) will be replaced when new dispatch consoles are procured. 13.6.1. CHP’s simulcast radio systems use the voting equipment to select which receive audio is presented to the dispatcher and which audio is retransmitted to the mobile units. The voting equipment receives audio Prepared by OCIO, Public Safety Communications Division, Office of Public Safety Communications Services System Enhancements Rev 04.3r4.doc Last Save Date: 6/1/2009 3:29 PM Page 28 of 86 13. 14.

CHP will continue to use vote steer in communications centers that are not currently operating with simulcast systems. New frequency pairs will be assigned to each simulcast area to facilitate duplex operation. Typically only one transmitter is selected at any given time.1.e. Each non-simulcast division will have a new unique division wide BLU frequency pair (automatic vote steer using the current Avtec dispatch console’s repeat function1) using one of the newly identified lowband frequency pairs.6.

This configuration enables transmission to a greater number of mobile units during each single transmission]. The simulcast areas dispatched by Border CC and Inland CC will each have a different BLU simulcast frequency pair different from the conventional BLU frequency pair used in the remainder of their respective divisions.1. 14. The separation of the BLU frequency will require the installation of new dedicated BLU base stations at remote radio sites.
