Delivering broadband services to the subscribers of the Public Safety Broadband Network (PSBN) can be achieved by several different approaches. Each approach entails different sets of actors in the service delivery fabric and different distributions of functions between the actors. Four approaches (options) are examined and compared for how they could satisfy fundamental requirements for (i) nationwide and agency-wide interoperability and (ii) operational efficiencies in delivering broadband service. The evaluation was based to a large degree on previous work by DRDC CSS that examined the technical underpinnings to achieve inter-working at the network level and interoperability at the service and user levels. In general, nation-wide interoperability can be more easily achieved by centralizing the functions that are implicated in delivering the services than by replicating those functions among independent regional actors. Furthermore, centralizing those key functions also leads to service delivery efficiencies because of reduced capital costs for the infrastructure and reduced costs to operate and maintain those functions. A hybrid option, between a fully centralized model and one consisting solely of independent regional actors, can be an efficient way to operate the PSBN and facilitate interoperability. The hybrid option consists of a national proxy of the regional actors to whom they would have delegated their authority to perform some of their functions. In all the option
