Countywide Law Enforcement

All police departments in Ingham County have a number designator assigned to the department.  
Most departments use this number as the first digit in their unit number. 
Lansing has their own dispatch channels, East Lansing/MSU have their own dispatch channel, and all other units share an out-county dispatch talkgroup. 
Lansing has several proprietary encrypted tactical/ops channels, as well as the sheriff department, and East Lansing/MSU also have their own. 
The tac channels are often setup to scan and also pick up traffic on the main dispatch channels. 
Groups, such as MSU parking enforcement and contracted security, have their own operations/tactical (and dispatch) talkgroups, but also have access to main dispatch and tactical channels. 
Michigan State University also uses MPSCS for IPF and transit, and they do have some common interoperability talkgroups with law enforcement.

- MSU Breslin Center, Special Events, and several campus security groups use analog UHF radios that could talk to the old Harris radios and had patches to that system. Most Breslin Center activity is on 469.75 MHz, most Special Events is on 462.6. Some facilities security also use analog radios, such as the Broad Art Museum, despite all having MPSCS capability. These are the last holdouts on UHF analog, after MSU Parking Enforcement and Greencoat Security in 2024. All other county security, law enforcement, public safety, as well as most public works are now on the MPSCS since 2021. MSU Special Events plan to get onto the MPSCS eventually. Breslin Center security may eventually transition to DMR. 
- All MPSCS-capable Ingham law enforcement and related radios have access to 33COM, 33ICMAIN, 33INGFIRE, 33ELMSU, MPSCS event channels, 700-MHz simplex, and 33SPEV1-10, and tri-county mutual aid channels. Police radios also have access to 33ICOPS, several other encrypted channels (LEIN, detectives, etc), and proprietary tac/ops channels, as well as dispatch and other channels for nearby counties.
- Each department has their own proprietary tac channel, and a few have several, as well as shared ops channels. Generally, 'tac' channels are in the clear and 'ops' channels are encrypted. Tac channels are car-to-car type talk and ops channels are for dispatch information that is secured from the public, and also used during some complicated events to keep information secure and avoid tying up dispatch channels.
