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*.
