Finnish TETRA PPDR Authority Radio Network VIRVE WG FM civil-military meeting 23.-24.11.2016 10.2016 Peteveikko Lyly

VIRVE network

Key facts of the group (VIRVE ~1/3) 300 94 84 300 Employees Employees Offices across Finland Annual turnover (MEUR) in 2015 Offices across Finland Estimated annual turnover (MEUR) in 2015

Services Data centres Virve Turvallisuusverkko IP-services Terminals Colocation services Capacity services Data communications Virve Turvallisuusverkko IP-services Terminals Situational awareness Krivat Johtotieto A unique range of ICT solutions for authorities and critical infrastructure enterprises – for those who do not settle for the ordinary.

VIRVE users are a restricted user group Ministry of Transport and Communication approves new user groups Price of the VIRVE service is heavily subsidized. Necessary to minimise influence to competition of public mobile phone operators. Both positive and negative decisions of applications Multivendor thanks to open standard and interoperability work

Frequencies of VIRVE TMO Frequency range DMO frequencies 380,2625-384,9875 MHz for TMO DMO frequencies 10 DMO frequencies 40 additional DMO frequencies 385-386 / 395-396 MHz Few will be changed from DMO to TMO Coordination of the usage with neighboring countries 50/50 principle Certain power level permitted Some frequency shortage in capital area, significant part of the frequencies can be used only partially due to agreement with southern neighbor country Estonia

Continuous re-investments

VIRVE is joint and the only network of all public safety authorities

Multi-channel router for improved reliability of mobile broadband

Current GSM-R will be replaced with VIRVE (TETRA) Very few new base stations Big savings Waiting for LTE

VIRVE transition from TETRA to LTE (4G, 5G etc) takes >10 years until complete

The Finnish Defense Forces is an active VIRVE-user Several thousands of terminals, about 15% of all VIRVE subscribers. Daily use is related to field exercises, Military Police, Fire and Rescue as well as authority co-operation Roughly 25% of the radio terminals are active on a daily basis Occasional usage when larger groups have exercises Several thousands of terminals, regular (quarterly) usage. Also fixed workstations and mobile data terminals with positioning and task management application across the whole country DMO channel(s) In addition to the nation wide VIRVE, Defense Force has deployable TETRA network (380-400 MHz area), which is used by the battalion on wheels. Deployable TETRA system is connected to VIRVE so user will be able to talk with ERC-center (112)

LTE has numerous teething issues e.g. DMO LTE Proximity services Very short range compared to TETRA In practice < 500 meters https://www.qualcomm.com/media/documents/files/lte- direct-trial-white-paper.pdf Wifi-LTE routers will reduce the problem TETRA DMO connection when LOS >5km Some users are still using VHF radios bought before VIRVE Used especially in DMO Mission Critical PTT over LTE will probably work, however infrastructure coverage will remain an issue Conclusion Usage of TETRA frequencies will continue at least until 2030 in Finland, even beyond 2035 No decisions concerning future use of the frequencies after TETRA
