Task: Management and Monitoring of theTETRA Interoperability Process

Top Priorities for 2006/2007:– Implementat New Certificate Formats– Encourage other (non-European) manufacturers to

join the Interoperability Process

Slide 5

What is Interoperability (IOP)

IOP ensures, that TETRA equipment from one manufacturer is working with TETRA equipment from another manufacturer, and vice versa.

IOP Testing gives the confidentiality,that purchased equipment is interoperable.

IOP ensures, that TETRA is an Open Standard.

IOP enables Multi-Vendormarket for TETRA

Slide 6

Benefits of open multi-vendor market

User benefits– wide choice of compatible certified terminals– specialised products for special needs– continuous and fast product innovation– continuous and genuine competition, hence lower prices– 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!

IOP Specification Process

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

Independent TETRA Certification Body

ISCOM is the official type approval body of Italy

Testing is performed at the infra-structure manufacturers premisessupervised by ISCOM

Test execution is traced and the test logs are used by ISCOM to check the compliance to IOP specs.

After careful analysis of the logs the certificates are issued and published on the TETRA MoU 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

Status of IOP Testing and Certification (1)

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 17

Status of IOP Testing and Certification (2)

In total 176 IOP Certificates issued

Testing and Certification for Inter-System

Interface (ISI) and Peripheral Equipment

Interface (PEI) has not started yet

Interoperability

Slide 18

Interoperability in Practice

Almost all TETRA networks use a mix of terminals from different vendors

High 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

Slide 19

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

in Asia

from a European-Centric to a Global Activity TETRA MoU would like to invite Asian companies

to join the IOP testing process.

The first Technical Forum Meeting outside of Europe will be held in Asia in February 2007
