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. 12.2.2013

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 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


• 2 What approximate speed would each subscriber receive? 30 Mbit/s @ 1500 m70 Mbit/s @ 1000 mAssumption: VDSL2 over POTS

Example graph of VDSL2 speed vs distance in Telekom Slovenije




• 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 / customerBackhaul / uplink: 20.000 EUR / kmTogether: approx 500 - 700 EUR / customerdepends on size and reconstruction of copper network (pairgain systems)



• 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


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


2. 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 1.000 WiFi access points for 5.000 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.

1.000 EUR / AP, 20.000 EUR / km, use electricity poles?


3. GSM or 3G Mobile network• 1 How would you upgrade this infrastructure to provide Next

Generation Access (NGA) - perhaps using 4G or LTEFirst 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: 20.000 EUR / km (ground) // 15.000 EUR / km (aerial)

Base station: 10.000 EUR / site (active equipment)


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


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


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


Sattelite - Skylogic

• Not for gaming, average good• 800 ms ping – QoE?
