Presentation on behalf of the TETRA + Critical Communications Association Current Status of TETRA and the Way Forward Ali Helenius Hungarian TETRA Forum Budapest, April 18th 1

Presentation on behalf of the TETRA + Critical Communications Association 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

Presentation on behalf of the TETRA + Critical Communications Association TETRA 2 Additions User Network owner Operator Enhanced cell radius for Air-Ground-Air ReliableAir-to-Groundcommunicationservices Spectrum efficiency Easy AGA roll-out Optimised total cost of ownership Low cost coverage LIP for advanced automatic location services Operationalefficiency and situational awareness awareness Controlled AVL load Terminal remote configuration configuration Optimised total cost of ownership Integrated TEDS for high speed data services New data applications Improve field command and situational and situational awareness awareness Secured network Investment Optimised total cost of ownership Easy deployment Extreme spectrum efficiency Complete system solution 1 23

Presentation on behalf of the TETRA + Critical Communications Association TETRA and Other Technologies vs Nationwide Public Safety Systems Functionality Ecosystem Nationwide

Presentation on behalf of the TETRA + Critical Communications Association All in MHz band Key Nationwide TETRA Regional TETRA Nationwide TETRA under construction Project in progress likely to be TETRA Tetrapol No project known European Public Safety Networks 7 Q status

Presentation on behalf of the TETRA + Critical Communications Association 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

Presentation on behalf of the TETRA + Critical Communications Association 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
