           – What is Interoperability and what is Interworking


   Interoperability Enablers

   Levels of Interoperability

   Recommendations & Summary

         Interoperability is More Critical than Ever,
                       but What is it?
   Many definitions of Interoperability
   Technology solutions were easier in the analogue world
   Procedural solutions have an impact
   Vision of solutions vary by Service
   We need to use common language to:
       – Clarify discussions
       – Help specify requirements
       – Separate operating conditions

 Optimal Interoperability means using the same technology

 Interworking is Interoperability. Right?

 What is Interoperability – to You?
 Cross Border – the ability to roam to neighboring network
 Cross Service – the ability to cooperate during incidents
 Ability to use terminals from multiple and competing
  vendors

   What is Interworking – is that all you want?
 • Control Room patching
 • Cross-connect technologies
 • Gateway Interfaces

Disasters have regrettably often been Major
  Motivators for Interoperability Planning
  Norway
         – Train accident in Asta, January 2000 followed several marine accidents
  Sweden
         – Disco Fire & EU Summit in Gothenburg
  United Kingdom
         – Hillsborough, Clapham, Kings Cross
  September 11th attacks were ―experienced‖ worldwide
         – Interoperability is getting more attention than ever
         – It is becomming inconceivable to plan for non-interoperability
  France
         – Decission being formalised to force Fire and Health to AcroPol
           network.
         – Arguments used are cost saving and need for Interoperability.

         “After each major event in recent
         history, the most glaring indication
         of success or failure by responding
         agencies has been their ability to
         effectively communicate with each
         other.”

Level 4: Gateway -- Interface Box
     Hardware component that sits between two
      networks
     RF or 4-wire audio links connect systems
     Provides audio only, no system specific features

Level 4: Gateway (Console Patch)
     Works Via: Radios talk via link established by dispatcher,
      unmanned interface box, or mobile apparatus
     Advantage:
            – Moderate cost to implement in addition to network cost
            – Links different system types or frequency ranges
     Disadvantage:
            – Connected systems must have complementary/overlapping coverage
            – Console patch is unavailable if control center is not operating
            – Advanced calling features unavailable to users: dispatch audio only
            – Reduced channel capacity – what were two independent channel
              resources are now one talkpath
            – System management ends at gateway boundary
            – Not for ad hoc use: pre-planning required on each system for channel
              crowding procedures and setup

Level 5: System Specific Roaming
   Works Via: Radios talk to each other via infrastructure or DMO using
    infrastructure
   Advantage:
           –      Covers large areas seamlessly
           –      Users can contact agencies across entire coverage area
           –      Can handle larger numbers of users
           –      No console intervention required
           –      All advanced features are available to users
   Disadvantage:
           – Additional planning and provisioning required on each system
           – Requirement for double RF coverage, more towers – and more spectrum
   Requirement:
           – All players adopt TETRA and enjoy competition within the open standards
             sphere.

Level 6: Standards-Based Shared Systems

  Works Via: All radios built to a standard (TETRA) talk to each other
   via infrastructure or in DMO
  Advantage:
         –    Interoperability at the turn of a dial
         –    Links different vendor systems
         –    ―Out of the box‖ interoperability, simple to set up infrastructure
         –    No console intervention required
         –    All advanced features are available to users
  Disadvantage:
         – Requires equipment to be built to same standard, usually happens via
           new/upgraded system purchase
         – Not all vendors build to standard. Interoperability holes are still possible

Interoperability Basics -- Keep it Simple
 Massive Incidents = Massive Stress
 Allow your Public Safety Responders to Respond
 Plan with your Neighbor’s Neighbors
        – Massive incidents will require massive response
 Direct Interoperable ―Everyday‖ Systems
        – From Pentagon after 9/11: Use your Interoperability
          tools regularly




12&13 June 2006               TETRA – Poland 2006           Slide 22
Recommendations & Summary
   Plan for the highest level of Interoperability
           – Accept nothing less – consider your
             stakeholders
   Public systems are great for communication
    from/to the public.
   TETRA is a high capacity solution and the
    tool for the Emergency Services Radio
    Communication
