TETRA Interoperability (IOP) Roger Dowling Board Member TETRA Association 28th February 2007 Mexico City

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

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 confidence that equipment they purchase from multiple manufacturers is interoperable. IOP ensures that TETRA is an Open Standard. IOP enables a Multi-Vendor TETRA market

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!

Structure of the TETRA Association Operator and Users Association (OUA) Technical Forum (TF) TETRA Association Security and Fraud Prevention Group (SFPG) Rail Forum Geographical Forums

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

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

Interfaces covered by TETRA IOP PSTN A I PSTN Base Station ISDN LSI NMI ISDN PEI PDN Base Station BSI PDN TETRA Switch Other TETRA Network Base Station DMI ISI TETRA Network AI: Air Interface DMI: Direct Mode Interface ISI: Inter-System Interface PEI: Peripheral Equipment Interface

IOP Certification Process TETRA Products Independent TETRA Certification Body Request for Testing TETRA IOP Profile (TIP) TEST SESSION TETRA IOP Test Plan Evaluation of Results TETRA IOP Certificate

Independent TETRA Certification Body ISCOM is the official Italian Type Approval body Testing is performed at the infra- structure manufacturers’ premises supervised 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

Interoperability Testing 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

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

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

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

The Way Forward Continuing success of TETRA in South America and Asia Increasing number of manufacturers in 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

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
