Interoperability between people, organisations, regions and equipment

1
Interoperability between people, organisations,
regions and equipment

• Middle East TETRA Conference
• Dubai May 2004
• Risto Toikkanen
• Nokia

11.05.2004
2
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

3
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

4
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
• Legislation and/or regulation
• Politics
• Operating procedures practices
• Information security
• Radio spectrum
• Incompatible technologies/equipment

In Europe the cross-border interoperability is
high on the EU/Schengen agenda.
5
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

6
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
• 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

8
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

9
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

11
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
