Agenda
• TETRA 1
• TETRA 2
• TETRA status today
• The next step
• Evolution principle
Presentation on behalf of the TETRA + Critical Communications Association
TETRA 1
• Comprehensive global digital PMR standard by ETSI
• Standardisation during 1990’s, first deployments 1997
• Originally targeted for analogue PMR replacement, and
improving security & offering advanced PMR functionalities
• Fitting needs of traditional PMR user segments : public safety,
transportation, utilities, industry
• Key content of the standard
– Voice + Data functionalities for PMR users
– Air Interface, Inter System Interface
– Security
Presentation on behalf of the TETRA + Critical Communications Association
TETRA Interoperability
• Interoperability required to guarantee compatibility of
equipments within multi-vendor environment, and properly
working end-to-end functionalities
• Scope : terminal-network and network-network interfaces
• TCCA in charge of the interoperability process
– TETRA Interoperability Profile specifications (TIP)
– Interoperability test plans
– Interoperability certification process
• First interoperability certificates granted 1999
• ~20 interoperability test sessions organized 2012

TETRA Globally
•
•
•
•
•
•
TETRA is present at all continents
Annual TETRA equipment market value ~1BEur
Hundreds of networks deployed
2+ million TETRA users
New TETRA projects launched all the time
Public Safety, Transportation, Utilities, Industry, Defence
• The North American market is opening to TETRA technology,
first networks are already in place in the USA and Canada

The Next Step after TETRA 2
•
•
•
•
PMR must evolve – TETRA 1&2 is not the end of the story
Basic PMR user requirements remain as they are
Will apply commercially existing LTE technology
Layered model : PMR/TETRA functionalities running on top of
the LTE telecomms layer
• Standardisation required for end-to-end functionalities and
interoperability
• Enables data applications and control centre integration
• Targeting to support migration from three different existing
narrowband PMR technologies : TETRA, TETRAPOL, P25
Presentation on behalf of the TETRA + Critical Communications Association
The Next Step - Challenges
• Broadband PMR standardisation efforts
– global standard migrating both TETRA, TETRAPOL and P25
– several standardisation bodies
– Europe – US co-ordination

Frequency allocation
PMR priority within LTE telecomms industry
LTE credibility for mission critical PMR voice service
Changing ecosystem, changing business models
Required investments
Presentation on behalf of the TETRA + Critical Communications Association
Evolution Principle
Differencies between regions/countries
- evolution timeline
- frequency allocation
- combining dedicated and commercial solutions

Presentation on behalf of the TETRA + Critical Communications Association
Summary
• Narrowband TETRA is offering advanced purpose-fit services
for mission critical users globally
• Further development of narrowband TETRA solutions
guaranteed by large existing TETRA installed base and
significant number of new projects introduced each year
• LTE technology selected as the basis for the next step of PMR
• Evolution from narrowband TETRA to LTE based Broadband
PMR is a long process
• Narrowband TETRA is expected to remain in operational use
until 2025-2030
