TETRA Interoperability (IOP)

1. TETRA Interoperability (IOP) Roger Dowling Board Member TETRA Association 28th February2007 Mexico City

2. Content of Presentation • What is TETRA Interoperability? • Benefits of an Open Multi-Vendor Market • TETRA Technical Forum • The Interoperability (IOP) Process • What is IOP Tested and Certified • Status of IOP Specifications and Certification • The Future for IOP

3. What is Interoperability (IOP)? • IOP ensures that TETRA equipment from one manufacturer functions (interoperates) with TETRA equipment from another manufacturer. • IOP Testing gives Users the confidencethatequipment they purchase from multiple manufacturers is interoperable. • IOP ensures that TETRA is an Open Standard. • IOP enables a Multi-VendorTETRA market

4. Benefits of an open multi-vendor market • User benefits • wide choice of compatible terminals – 9+ suppliers • specialised products for special needs • continuous and fast product development & innovation • genuine competition, hence lower prices (c.f. P25) • reduced dependency on a single supplier • Industry benefits • larger market, greater volumes • increased possibility to invest – faster product creation • Market longevity The TETRA Association created the IOP certification process to guarantee an open multi-vendor market!

5. Structure of the TETRA Association Operator and UsersAssociation (OUA) Technical Forum (TF) TETRA Association Security and FraudPrevention Group (SFPG) Rail Forum Geographical Forums

6. Technical Forum • Open to all Members • 5 Meetings per Year • Website and Mailing List • Task: Management and Monitoring of theTETRA Interoperability Process • Top Priorities for 2006/2007: • Implement new format Certificates • Encourage new (non-European) manufacturers to join the Interoperability Process

7. IOP Specification Process • A formal process managed by the TETRA Association Technical Forum • Users to define Requirements and Priorities • Manufacurers to provide technical expertise

12. Independent TETRA Certification Body • ISCOM is the official Italian Type Approval body • Testing is performed at the infra-structure manufacturers’ premisessupervised by ISCOM • Test logs are checked by ISCOM to ensure compliance to IOP specs. • After careful analysis of the logs, certificates are issued and published on the TETRA Association web-site Photo by ISCOM

13. Protocol Stack Testing mainly Layer 3 signalling some parts of Layer 2 Frequency Independent Testing IOP Certificate is valid for all frequencies IOP Testing does not cover: Type Approval Testing EMC Testing Electrical Safety Testing RF Conformance Testing Interoperability Testing

14. IOP Certificates - issued • 12 Manufacturers participate in IOP Testing: • 8 companies have received TETRA infrastructure certificates for 9 systems • 9 companies have received TETRAterminal certificates in trunked mode • 6 companies have received TETRA terminal DMO certificates • 2 companies have received TETRAterminal DMO gateway certificates

15. Status of IOP Testing and Certification • In total 176 IOP Certificates issued • TIP specifications are the property of the TETRA Association and available free of charge to members of the Association • Certificates available for download:www.tetramou.comUsing TETRA Interoperability

16. Interoperability in Practice • Almost all TETRA networks use a mix of terminals from different vendors • Increased innovation speed: • more than 30 new terminal models have been launched during the last 3 years. • terminals with GPS receivers and colour displays • An increasing number of application developers rely on the TIP specifications and the IOP process • Many Users and Operators ask for IOP Certificates when purchasing new equipment

17. A selection of multi-vendor TETRA systems

18. Interoperability in Practice • Almost all TETRA networks use a mix of terminals from different vendors • Increased innovation speed: • more than 30 new terminal models have been launched during the last 3 years. • terminals with GPS receivers and colour displays • An increasing number of application developers rely on the TIP specifications and the IOP process • Many Users and Operators ask for IOP Certificates when purchasing new equipment

19. The Way Forward • Continuing success of TETRA in South America and Asia • Increasing number of manufacturersin Asia – and South America? • The first Technical Forum Meeting outside of Europe was held in China in January 2007 • From a European-Centric to a Global Activity

20. Conclusion • The multi-vendor environment achieved with is unique in Professional Mobile Radio, there is no other technology that can compare in terms of: • Number of suppliers • Number of different products • Price / Performance figures TETRA
