Boston Area Police Emergency Radio Network by Gary Saffer    from: The Eastern Mass Scanner Guide

 

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.

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.
