Various dimensions of Interoperability
  - Global issues in Public Safety & Security

  Organisational interoperability
    – Between agencies/organisations
    – Between people
  Regional interoperability
    – Between regions
    – Across national borders
  Technical interoperability
    – Between equipment
Organisational dimension
Organisational interoperability:
“Capability for agencies to communicate
  with each other”
       – On a daily basis
       – In emergency situations

                    Hurdles
                    • Legislation and/or regulation
                    • Operating procedures &
                      practices
                    • Information security
                    • Radio spectrum
                    • Incompatible equipment
     Inter-regional dimension
Inter-regional interoperability:
“Capability for peer agencies to
  communicate across borders”
    – Between regions
    – Across national borders
    – New dimension: cross-agency & cross border
Hurdles
                                          In Europe the
•   Legislation and/or regulation
                                          cross-border
•   Politics                              interoperability
•   Operating procedures & practices      is high on the
•   Information security                  EU/Schengen
•   Radio spectrum                        agenda.
•   Incompatible technologies/equipment
         Technology dimension
Technical interoperability:
“Process to ensure that equipment from
  multiple vendors are compatible”
     – Problem-free operation
     – Wanted functionality
     – In practice it is about protocol conformance
Hurdles
•   Standardisation
•   Standard conformance
•   Verification and certification
•   Competitive environment
•   Customer preferences
•   Backward compatibility
Organisational interoperability:
           solutions
Operating procedures
  – Agreements
  – Training
Dedicated radio channels
  – Common technical specification
  – Agreed procedures
Radio spectrum harmonisation
  – In some form this is a must
Technology harmonisation – standards
  – Necessary to gain radio compatibility
Shared networks
  – By far the most efficient tool
  – Requires high-tech system to ensure privacy   BEST RESULT
  – Both operational benefit and cost benefit
        Regional interoperability:
               solutions
1. Political & organisational readiness
2A. Conventional technical measures
•   Extra equipment like cellphones
•   Extended coverage across border or repeaters
•   Control room interconnect by wireline
•   Radio swap between control rooms e.g. Belgium & France
•   Radio swap between users

2B. Network interconnect
•   TETRA Inter-System Interface (ISI)
•   Three-country pilot Belgium – Germany – The Netherlands
•   Cross-network PMR functionality, first time
•   True cross-agency & cross-border opportunity
        Three-Country Pilot (1)
• Agreement between the governments of Belgium, Germany
  and The Netherlands
• Based on the requirements of the Schengen Agreement on
  cooperation of police forces and customs across the
  national borders
• To pilot cross-border functionality with TETRA ISI
• To create operational scenarios
   Three-Country Pilot (2)

• Phase 1 pilot testing completed in 2003 by
  use of pre-ISI solutions
• Operational scenarios built and tested in
  practice
• final report published at
  www.3countrypilot.com

• Phase 2 ongoing now with operational
  requirements specification for the TETRA
  ISI produced in 2004

• Winner of Outstanding contribution to
  TETRA award in TWC 2003
• please see www.3countrypilot.com
       Technical interoperability:
              solutions
  Solutions are deeply technical
  Decisions are done in early development phase

Cross-technology interoperability
• Specific operating modes like analog FM radio channels

TETRA Interoperability
• The TETRA Interoperability (IOP) concentrates on
  technical interoperability certification of multi-vendor
  TETRA equipment.
• Successful IOP certification is fundamental in creation of
  open multi-vendor market.
• Open multi-vendor market is fundamental for the success
  of TETRA - and it has happened
    Benefits of open multi-vendor
                market
User benefits
•   wide choice of compatible certified terminals
•   specialised product for special needs
•   continuous and genuine competition
•   less dependency - lower risk of market disturbances


Industry benefits
• wider market, bigger volumes
• more possibility to invest – faster product creation
• longer lifetime of market

TETRA MoU Association runs the IOP certification process to
  guarantee open multi-vendor market
  TETRA IOP Certification process
                                                      ACCEPTED into OPERATION
                                                       (Also need CE mark or TA)

                       Conclusions
Organisational interoperability
• Best cooperation is achieved by a shared
  network
• Current TETRA technology allows privacy
  and sharing
• Not to forget the cost savings by sharing
Regional interoperability
• Becoming more & more important
• TETRA ISI is the tool for network
  interconnect
