About

Home Office awarded a contract to Etherstack Wireless Limited for the provision of a TETRA/MCX Interworking Gateway (IWG) solution to the Emergency Services Mobile Communications Programme (ESMCP).

The IWG will support the transition from Airwave to ESN for approximately 300,000 users across 107 User Organisations by linking 6000 busiest Airwave talk groups to their equivalent new ESN talk groups, enabling migrated ESN users to make and receive Group and Emergency Calls with unmigrated Airwave users.

The solution is a software product deployable on physical or virtual servers provided by the ESN User Services Supplier, who will handle service integration and first/second line maintenance, while Etherstack Wireless Limited provides third line support.

The interface between Airwave and the IWG is DCS (Motorola DIMETRA™ Dispatch Communications Server), with 600 active DCS ports plus 300 resilience ports assigned, serviced by three Airwave DCS data centres.

The contract value is AUD 14,246,433.64.
