TETRA Interoperability (IOP)
Roger Dowling
Board Member TETRA Association
28th February 2007
Mexico City
Slide 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
Slide 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 confidencethat equipment they purchase from multiple manufacturers is interoperable.
IOP ensures that TETRA is an Open Standard.
IOP enables a Multi-VendorTETRA market
Slide 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!

Open to all Members
5 Meetings per Year

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
Slide 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

Slide 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

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
Slide 14
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
Slide 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:

Slide 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

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
Slide 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
