The Metropolitan Mobile Radio (MMR) network is the State’s dedicated emergency services secure digital radio network providing mission-critical digital voice services across metropolitan Melbourne and Geelong.

The network is used by Victoria Police, the Metropolitan Fire Brigade (MFB), Ambulance Victoria (AV) and the Emergency Services Telecommunications Authority (ESTA). Victoria State Emergency Service (VICSES) and Corrections Victoria will be transitioning onto MMR during 2018.

The MMR Service Agreement (MMRSA) was originally signed between the State and Motorola Solutions in 2004 for Motorola to design, build and provide support and maintenance services to the network and radio devices.

As part of the State’s Emergency Management Operational Communications Program, the MMRSA has now been extended by a further seven years to 7 July 2025, with the option to extend one or more times up to a total of five years to 7 July 2030.

The contract extension provides for various system and operational enhancements, including network upgrades and a complete radio terminal refresh program for the user agencies.

The MMR network provides:

  • enhanced security of communications through digital encryption facilities;
  • high quality digital voice and narrowband data transmission capability;
  • sufficient channel capacity and flexibility to manage the security and emergency response to major events;
  • interoperability between emergency service organisations and common co-ordination channels to support a multi-agency response to major incidents; and
  • statewide roaming capability between MMR and the State’s Regional Mobile Radio network.
