Next Generation Network planning

Designing & planning NGA networks requires analysis of:

Technical issues Commercial requirements Demographic information

Plan Design Enable

Sustainability requires more…..

• The vision for the scheme, area, district or county!

• The development of policy and strategy;

• Consideration of socio-economic requirements;

• Systems architecture and design;

• Cost and revenue modelling;

• Carbon neutral/green issues;

• Financing & consideration of EU State-aid implications;

• Procurement, planning and execution;

• System implementation & timelines;

• Ongoing network operation, management and maintenance.

• Core Co-Location Space

• GPON

• 1:32 Split@70Mbps & ~1.6KW; ~3500 Clients Served Per 5m2

• WDM-PON• 1:32 Split@100Mbps & ~1.2KW: ~2000

Clients Served Per 5m2

• 1:16 Split@1Gbps & ~1.6KW: ~2000 Clients Served Per 5m2

• Additional Space Required For;• Optical Distribution Frames (External fibres,

Internal Patching, etc)

• Uninterruptible Power Supplies

• Cooling

How can Utility Companies help?

• Power Distribution Companies

• Spare co-location space in substations – secure!

• Fibre communications immune to electromagnetic interference.

• Water Companies • Spare co-location space in water and waste water

treatment plants, remote pumping stations etc?

• FTTP via the waste water system.

• Combine with Sub-Loop Unbundling• FTTC+FTTP via waste water system

The Distribution Network

• Ducts or Overhead?

• Fibre in ducts - Life <25 Years;

• Fibre via overhead - Life <10 Years.

• Re-use existing “Open-Access” infrastructure :

• How far do these infrastructures penetrate locally?

• Can Sub-Loop Unbundling help? FTTC+last FTTP drop.

• Potential to ‘collaborate’ with private utility organizations to:

• Coordinate assets, costs and connectivity;

• Use properly designed ducts infrastructure to maintain future Open-Access capability.

The Access Network

• Ducts or Overhead?

• As before.

• Where to locate equipment?

• PON Splitters: Street cabinets, buried box, LAN room?

• Ethernet: Needs power: Street cabinet or LAN room?

• Each deployment is different, no “one-size-fits-all” solution.

• Properly designed duct infrastructure to maintain future ‘Open-Access’ capability;

• Section 106 Rules can help.Access

Financial Modelling• Revenue modelling

• Economic analysis (Funding Models, RoI);• Customer profiling;• Service mixes, uptakes and timelines.

•Cost modelling•Re-use of existing infrastructure?;•Civil works and street furniture;•In-building infrastructure;•Core network including backhaul and ‘Managed Internet’ connectivity;•Access technologies;•Ongoing operations, management and maintenance.

• Sensitivity Analysis

• Impact of customer take-up RoI and Investment Case;• Impact of technology choices & network elements on cost;• Impact of geographical disparities in economic growth.

Carbon Impact

• FTTP can significantly reduce need to travel

• Face-to-face using video such as tele-presence• Remote diagnosis using tele-medicine• Etc.

• UK Power Conversion Factor:

• For every 1KwH used in the UK 0.843Kg of CO² is produced*.
