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.
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
3, ENGAGE Donegal case. 12.2.2013
1. Copper-based basic ADSL 2/4
• 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
4, ENGAGE Donegal case. 12.2.2013
1. Copper-based basic ADSL 3/4
• 3 Would you upgrade by providing Fibre-to-the-Cabinet (FTTC) or Fibre-tothe-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)
5, ENGAGE Donegal case. 12.2.2013
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
6, ENGAGE Donegal case. 12.2.2013
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
7, ENGAGE Donegal case. 12.2.2013
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?
8, ENGAGE Donegal case. 12.2.2013
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 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
10, ENGAGE Donegal case. 12.2.2013
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
11, ENGAGE Donegal case. 12.2.2013
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
12, ENGAGE Donegal case. 12.2.2013
Sattelite - Skylogic
• Not for gaming, average good
• 800 ms ping – QoE?
