  1. ENGAGE Donegal workshop Letterkenny, February 12th2013 Matjaž Pogačnik, MBA

  2. 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. 1. 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 pairgainsystems (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. 2 What approximate speed would each subscriber receive?  30 Mbit/s @ 1500 m 70 Mbit/s @ 1000 m Assumption: VDSL2 over POTS Example graph of VDSL2 speed vs distance in Telekom Slovenije 1. Copper-based basic ADSL 2/4

  5. 1. 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: 20.000 EUR / km Together: approx 500 - 700 EUR / customer depends on size and reconstruction of copper network (pairgain systems)

  6. 1. 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. 2. 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. 2. Fixed Wireless Access (FWA) 2/2 • 2 Whatapproximatespeedwouldeachsubscriberreceive? Page 1Designing a HighSpeedBroadband (HSB) solutionforCountyDonegal 30Mbit/s guaranteed • 3 Wouldthenumber (density) of base stationsneed to beincreased?  Implement cca 1.000 WiFi access points for 5.000 users • 4 Howmuchwould it cost (in euro) assuming that each existing FWA base station is approximately 3 Kilometres from the nearest backhaul point. 1.000 EUR / AP, 20.000 EUR / km, use electricity poles?

  9. 3. 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 Whatapproximatespeedwouldeachsubscriberreceive?  Besteffort. Max is not yet defined. 70 Mbit/s per sector (optimistic) • 3 Wouldthenumber (density) of base stationsneed to beincreased ? 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: 20.000 EUR / km (ground) // 15.000 EUR / km (aerial) • Base station: 10.000 EUR / site (active equipment)

  10. Alternative Infrastructure • ElectricityNetwork • Theelectricitynetwork is shown in Map 4 on page 17. • Thiscontains a mixof 110KV and 38KV powerdistributionlines. 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. Couldthis last mile electricitynetworkbe used to as a HighSpeed Access networkforbroadband • 2. Describethetechnicalsolution • 3. Whatare thelimitations or constraints

  11. 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. 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. Sattelite - Skylogic • Not for gaming, average good • 800 ms ping – QoE?
