System architecture, functional requirements and some of the implementation requirements can now be integrated into preliminary system design. By now you should be able to define:

  • technology (P25 conventional or trunked, Phase 1 or Phase 2),
  • system architecture (single site, Simulcast, Multicast, hybrid),
  • RF sites; existing or new (green), number and locations,
  • channels per site – approximate number,
  • consoles and auxiliary equipment (logging recorders) – numbers and location,
  • dispatch equipment functionality,
  • backhaul network architecture, approximate capacity and functionality,
  • interoperability needs – participating organizations, their technologies and your desired level of integration,
  • subscriber equipment – approximate quantities and functionalities,
  • administrative (system management) desired features and functionality,
  • diagnostic and maintenance features.
