EU DIGITAL AGENDA FOR SLOVENIA FTTN, FTTH and LTE using the same (existing) infrastructure of TS Starting point: Re-use of existing network The individual household addresses and accurate infrastructure data have been taken into account in the analysis. Already existing infrastructure is used for FTTN, FTTH and LTE backhaul.

3, ENGAGE Donegal case Copper-based basic ADSL 1/4 1. How would you upgrade this infrastructure to provide Next Generation Access (NGA)? FTTN / VDSL2 Assumptions / Questions What is the maximum distance to the customers? Does every houshold have access to copper cables? Are there any pairgain systems (or other bottlenecks, e.g. bridget taps, loading coils, …) in the copper network? What is the diameter of the copper pairs? Does incumbent offer LLU (Unbundled Local Loops)? Table 2: not representing the number of customers

4, ENGAGE Donegal case What approximate speed would each subscriber receive? m m Assumption: VDSL2 over POTS Example graph of VDSL2 speed vs distance in Telekom Slovenije 1. Copper-based basic ADSL 2/4

5, ENGAGE Donegal case Copper-based basic ADSL 3/4 3 Would you upgrade by providing Fibre-to-the-Cabinet (FTTC) or Fibre-to- the-Premises (FTTP) ? In the part of assuring goals of EDA with FTTN solution that would be more FTTC. Each FTTN location would cover capacities from 32 to 192 subscribers. 4 Would the number of exchanges need to be increased? The number of exchanges could stay the same. We would have to significantly increase the number of FTTN/C locations. 5 Would the number of cabinets need to be increased? Yes. The number of cabinets should be increased significantly 6 How much would the total cost (in euro) of the upgrade be assuming that each existing Cabinet is an average of 1 Kilometre from the exchange? Active equipment: 100 – 300 EUR / customer Backhaul / uplink: EUR / km Together: approx EUR / customer depends on size and reconstruction of copper network (pairgain systems)

6, ENGAGE Donegal case Copper-based basic ADSL 4/4 7 Do you know of any alternative or new solutions that could applied to this ADSL access infrastructure From our point of view is the most reasonable assuring the goals of EDA with reusing existing capacities of access network. VDSL2 with vectoring could extend delivering broadband services over copper networks. Vectoring can almost double speeds at the same distance 1000m

7, ENGAGE Donegal case Fixed Wireless Access (FWA) 1/2 1 How would you upgrade this infrastructure to provide Next Generation Access (NGA) Optical backhaul and mesh WiFi hotspots

8, ENGAGE Donegal case Fixed Wireless Access (FWA) 2/2 2 What approximate speed would each subscriber receive? Page 1Designing a High Speed Broadband (HSB) solution for County Donegal 30Mbit/s guaranteed 3 Would the number (density) of base stations need to be increased? Implement cca WiFi access points for users 4 How much would it cost (in euro) assuming that each existing FWA base station is approximately 3 Kilometres from the nearest backhaul point EUR / AP, EUR / km, use electricity poles?

9, ENGAGE Donegal case GSM or 3G Mobile network 1 How would you upgrade this infrastructure to provide Next Generation Access (NGA) - perhaps using 4G or LTE First phase: upgrade of existing locations with new technology Which frequencies are in use? Has there been LTE frekvencies tender yet? 2 What approximate speed would each subscriber receive? Best effort. Max is not yet defined. 70 Mbit/s per sector (optimistic) 3 Would the number (density) of base stations need to be increased ? Not in first phases 4 How much would it cost (in euro) assuming that each existing FWA base station is approximately 3 Kilometres from the nearest backhaul point. optical cable: EUR / km (ground) // EUR / km (aerial) Base station: EUR / site (active equipment)

10, ENGAGE Donegal case Alternative Infrastructure Electricity Network The electricity network is shown in Map 4 on page 17. This contains a mix of 110KV and 38KV power distribution lines. However, most premises in rural areas receive electricity via last mile cables erected on poles. Use for bachaul for FTTN and Base stations / FWA 1. Could this last mile electricity network be used to as a High Speed Access network for broadband 2. Describe the technical solution 3. What are the limitations or constraints

11, ENGAGE Donegal case Clean Water Distribution Network The clean water distribution network is also shown in on Map 4 on page 17. Clean water is distributed along village streets and roads in 45 Centimetre pipes 1. Could this clean water network be used to as a means to deliver broadband to street cabinets 2. Is it permitted to use clean water pipes in this way 3. Describe the technical solution 4. What are the limitations or constraints

12, ENGAGE Donegal case Sewage Network All towns (see Table 1 -Towns & Villages in County Donegal ranked by Populations on page 5) contain sewage networks which connect to all premises within the town boundary via pipes of 23 Centimetres in diameter. 5. Could this sewage network be used to as a High Speed Access network for broadband 6. Describe the technical solution 7. What are the limitations or constraints

13, ENGAGE Donegal case Sattelite - Skylogic Not for gaming, average good 800 ms ping – QoE?
