    Philip Atherton NextGen 09 Philip Atherton NextGen 09 Presentation Transcript

    • Next Gen ‘09 Presenter: Phil Atherton Principal Consultant Date: November 2009
    • Next Generation Network planning
      • Designing & planning NGA networks requires analysis of:
        • Technical issues
        • Commercial requirements
        • Demographic information
    • 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.
    • Network Elements Council/Partner/Utility Offices 32x100Mbps/16x1Gbps (WDM-PON) 32x70Mbps (GPON) Council Office Electricity Substation Water Treatment Works 20Km (GPON) or 40Km (WDM-PON) Internet Distribution Access Core  1 ,  2 ,  3 Cabinet or Buried Box Splitter Business Park  1  2 Local Office or Residence ONT ONT <10Km <10Km <10Km) Ethernet = 100Mbps Network Core Backbone (n x 10Gbps) A = <10Km B = <10Km C = <10Km Equipment Equipment Equipment LAN Rooms  1 ,  2 ,  3  1 ONT  1 ,  2 ,  3 Cabinet or Buried Box Splitter
    • The Core
      • Core Co-Location Space
        • GPON
          • 1:32 Split@70Mbps & ~1.6KW; ~3500 Clients Served Per 5m 2
        • WDM-PON
          • 1:32 Split@100Mbps & ~1.2KW: ~2000 Clients Served Per 5m 2
          • 1:16 Split@1Gbps & ~1.6KW: ~2000 Clients Served Per 5m 2
        • Additional Space Required For;
          • Optical Distribution Frames (External fibres, Internal Patching, etc)
          • Uninterruptible Power Supplies
          • Cooling
      Internet Core Network Core A = <10Km B = <10Km C = <10Km Council Office Electricity Substation Water Treatment Works
    • 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.

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