Topics • New sectoral market needs • Case study: Smart Grids in Power Engineering • New tools to facilitate spectrum sharing 2

New sectoral market needs • Drone and aeronautical mobile video communications • Specific sector usage: lightning and thunderstorm clouds research in higher levels of atmosphere. C 2 -cat. drone under consideration. Frequency? • 1. 8/1. 9 GHz, 5000 -5010 MHz, . . . • Wide-band communication of PPDR-assisting services: mobile video, including helicopters, during rescue operations (fire brigade, ambulance, police). • 2. 3 GHz under consideration. 3

Case study: Smart Grids in Power Engineering • Smart Energy • Power generation, energy distribution and metering; energy storage; services • Communication needs: interconnection among energy producers, consumers and „prosumers“ (=consumers with energy production). New challenge: electro-mobility. • Power distribution network requirements: safety + reliability (critical infrastructure) • Core of communication solution: Fiber-optic network. But… 4

Case study: Smart Grids in Power Engineering • Challenge • Many physical elements of energy networks (power transformers, poles, switches, metering) are located remotely. • Hilly country side plays role too. • Number of (fixed) terminals: thousands 5

Case study: Smart Grids in Power Engineering • Solution: radio • Features of new energy-related radio network: • Switches and metering: ≈ 1 kbit/s (max. ≈ 10 kbit/s); transformer stations: ≈ 10 kbit/s (max. ≈ 100 kbit/s); several short messages per minute; latency ≈ 100 ms • BTS traffic: 6 Mbps/sector. More traffic in uplink. • BTS backhaul: optical network • Number of BTS: a few hundreds 6

Case study: Smart Grids in Power Engineering • Preffered band • Coverage plays role • 400 MHz band considered for such radio network solution 7

Case study: Smart Grids in Power Engineering • Public or private dedicated network? • Smart grids network of energy distributor falls under 3 laws: • Telecommunication Law • Critical infrastructure and Cybersecurity Law • Energy distribution Law • It is challenging to meet requirements of all the 3 Laws. • Solution: • Dedicated wideband smart-grid private radio network • 400 MHz band, LTE-M (M 2 M) BW 1, 4 MHz; duplex operation • Possible shared usage with other non-public criticalinfrastructure users (gas/oil/water distribution) • Launch of deployment: 2020, gradual increase of usage until 2030 8

New tools to facilitate spectrum sharing • Several bands under consideration of new ways of usage • 60 GHz band: relaxation of spectrum usage conditions (outdoor operation of SRD, MGWS, Pt. P and other systems), based on licence exemption. • To support coexistence, semi-coordination tool for spectrum users (coordination calculator, online map and database of registered stations, …) will be introduced (in Czechia). • 6 GHz band - under study in CEPT of possible RLAN/WAS usage based on sharing. Compatibility with other services: advanced semi-coordination tools (incl. geo-location) could be a part of solution. 9

New tools to facilitate spectrum sharing • Several bands under consideration of new ways of usage • 5. 8 GHz band: to facilitate WAS/RLAN sharing with other services, Czechia revealed Project on light-licensing approach (see CPG PT-D). • 26 GHz (5 G incl. M 2 M): besides traditional „IMT-licensing regime“ (ie. regional or nationwide licences), other ways of flexible of hybrid authorisation are considered, taking into account hot-spot and indoor 5 G-usage. • Other bands? (5 GNR 70 GHz, …) 10

New tools to facilitate spectrum sharing • Solution: „managed approach“ • Opportunities: • Role of self-regulation • Uncoordinated ad hoc deployments • Light-touch licensing • … • Common feature: managed approach of shared spectrum use, based on knowledge of existing usage (e. g. Open Data) and involving new techniques (cognitive radio, …). 11
