Boston Area Police Emergency Radio Network (BAPERN)

 

BAPERN was originally conceived in the early and mid seventies as a system to allow police departments in the greater Boston area to be able to communicate with each other while at the same time having discrete local operating frequencies. As conceived, it would go beyond the existing intercity system, which only allowed base stations to communicate and would allow mobile and even portable radios from different agencies to communicate directly via a system of district and region wide repeaters. This would allow for joint operations to be coordinated on one set of frequencies as opposed to a patchwork of different bands and frequencies.

 

In addition to the Local frequencies known as BAPERN 1 there are district and regional frequencies as listed below. A few systems also have a second local operations frequency that may be used for a variety of purposes. BAPERN 3 is the primary intercity frequency used in the system. Pursuits will often be simulcast on the local channel and BAPERN 3. Also descriptions of wanted persons will be broadcast.

 

New Channel layout for eastern MA PDs. This will include BAPERN communities and other regional networks as well. All mobile and portable radios will be reprogrammed to match. This is effective June 5, 2006.

In addition to the above agencies the Boston Police, State Police, and several federal agencies have capabilities on the BAPERN district and regional frequencies. Foxboro has access but is not a member of BAPERN. Several of the University and College Police Departments in the Boston area also can communicate on the system.

 

Cambridge Police Department

 

 

The Cambridge Police Department operates on the city's 800 MHz trunked system, with Channel 1 simulcast on 470.3125. Cambridge recently converted to a Type II Motorola system, so no fleet map is needed. Frequencies are 856.7875, 857.7875, 858.7875, 859.7875, 860.7875, 868.7875, and 853.2625. These are the Cambridge Police Talk Groups.  Recently licensed are 866.800, 867.300, and 867.6875 which it appears will be used to extend system coverage underground to several MBTA stations in Cambridge.

866.800 with D-155 is patched with TG 17472 to provide coverage in the MBTA tunnels.

853.2625 D-125 is also licensed, but exact use is unknown.

867.4375 PL 146.2 is used by MIT Police.

It appears that Chelsea PD has abandoned their BAPERN numbers in favor of the following system.

Sector 3:                                                 Cary Ave./Broadway/Revere Line

Sector 4:                                                 Bellingham Square/Broadway/East Boston Line

 

Some sectors have more than one car assigned. In those cases the call signs will be “4 Alpha, 4 Delta”, and so on. “Routes” seem to be walking officers.
