4 Migra+on scenarios and +meline Start with TETRA U.lize LTE as a supplement Pictures, videos via LTE, non-mc voice on LTE via APP Pico cell, public LTE, WiFi. When MC-LTE becomes available, use it where applicable Prerequisites Frequency availability Mission cri.cal features within LTE Terminals suppor.ng LTE & TETRA simultaneously (no one wants to carry two terminals) 4

5 Migra+on scenarios and +meline Standardiza.on and development.melines (TCCA study on TETRA, LTE and other broadband technologies for cri.cal communica.ons markets, P3 Communica.ons GmbH, Feb. 2015) 5

6 Overview Migra.on scenarios and.meline Interworking of TETRA and LTE 6

7 Interworking of TETRA and LTE Today: Pictures, videos via LTE, non-mission cri.cal voice on LTE via smart phone applica.on Low level users will just use a smart phone Medium level users run on TETRA terminals High level users require LTE / TETRA hybrid terminals Integra.on on protocol level between TETRA/LTE already ongoing, but can only be finalized once MC-LTE is completed 7

8 Interworking of TETRA and LTE In future: System interface, group calls, numbering schemes, priority and pre-emp.on, interna.onal roaming, gateways, All in one integrated network management All in one integrated logging system All in one integrated dispatching system Appearing to be one coherent system But being a cross technology communica.on 8

9 Overview Migra.on scenarios and.meline Interworking of TETRA and LTE How long will we need TETRA networks? 9

10 How long will we need TETRA networks? First LTE R14 products available in (TCCA/P3 study, Feb. 2015) Mission Cri.cal Push To Talk (MCPTT) Group Communica.ons Service Enablers (GCSE) Isolated E-UTRAN Opera.on for Public Safety (IOPS) Quality of Service(QoS) Before this there is the vendor lock in proprietary solu.ons Op.on for private LTE networks available: Na.onwide networks Small countries or countries with less frequency restric.ons Large industries which can afford frequency fees Usable for large systems, but thereby minority of systems 100

11 How long will we need TETRA networks? Also public LTE based on Telco provider network can be improved and offer such features, but Be aware of maintenance, shut down and service restric.on being out of control No big interest from commercial LTE operators: High risk and effort, low earnings Afraid of premium customers Limited poten.al, but can be a good supplement And what about TETRA? Fully available today Will co-exist with LTE minimum in the first decade Open standard with tested interoperability on mature technology Safe investment today, as future proof paths will be available 111

12 Conclusion LTE will develop S.ll several years to go Features need to be standardized Products need to be available and interoperable Safe investment today is: TETRA for voice Poten.ally supplement with LTE or WiFi for broadband data TETRA is future proof due to co-existence and interopera.on with LTE 122
