Philip Atherton NextGen 09

  1. 1. Next Gen ‘09 Presenter: Phil Atherton Principal Consultant Date: November 2009
  2. 2. Next Generation Network planning <ul><li>Designing & planning NGA networks requires analysis of: </li></ul><ul><ul><li>Technical issues </li></ul></ul><ul><ul><li>Commercial requirements </li></ul></ul><ul><ul><li>Demographic information </li></ul></ul>
  3. 3. Sustainability requires more….. <ul><ul><li>The vision for the scheme, area, district or county! </li></ul></ul><ul><ul><li>The development of policy and strategy; </li></ul></ul><ul><ul><li>Consideration of socio-economic requirements; </li></ul></ul><ul><ul><li>Systems architecture and design; </li></ul></ul><ul><ul><li>Cost and revenue modelling; </li></ul></ul><ul><ul><li>Carbon neutral/green issues; </li></ul></ul><ul><ul><li>Financing & consideration of EU State-aid implications; </li></ul></ul><ul><ul><li>Procurement, planning and execution; </li></ul></ul><ul><ul><li>System implementation & timelines; </li></ul></ul><ul><ul><li>Ongoing network operation, management and maintenance. </li></ul></ul>
  4. 4. 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
  5. 5. The Core <ul><li>Core Co-Location Space </li></ul><ul><ul><li>GPON </li></ul></ul><ul><ul><ul><li>1:32 Split@70Mbps & ~1.6KW; ~3500 Clients Served Per 5m 2 </li></ul></ul></ul><ul><ul><li>WDM-PON </li></ul></ul><ul><ul><ul><li>1:32 Split@100Mbps & ~1.2KW: ~2000 Clients Served Per 5m 2 </li></ul></ul></ul><ul><ul><ul><li>1:16 Split@1Gbps & ~1.6KW: ~2000 Clients Served Per 5m 2 </li></ul></ul></ul><ul><ul><li>Additional Space Required For; </li></ul></ul><ul><ul><ul><li>Optical Distribution Frames (External fibres, Internal Patching, etc) </li></ul></ul></ul><ul><ul><ul><li>Uninterruptible Power Supplies </li></ul></ul></ul><ul><ul><ul><li>Cooling </li></ul></ul></ul>Internet Core Network Core A = <10Km B = <10Km C = <10Km Council Office Electricity Substation Water Treatment Works
  6. 6. How can Utility Companies help? <ul><li>Power Distribution Companies </li></ul><ul><ul><li>Spare co-location space in substations – secure! </li></ul></ul><ul><ul><li>Fibre communications immune to electromagnetic interference. </li></ul></ul><ul><li>Water Companies </li></ul><ul><ul><li>Spare co-location space in water and waste water treatment plants, remote pumping stations etc? </li></ul></ul><ul><ul><li>FTTP via the waste water system. </li></ul></ul><ul><li>Combine with Sub-Loop Unbundling </li></ul><ul><ul><li>FTTC+FTTP via waste water system </li></ul></ul>
  7. 7. The Distribution Network <ul><ul><li>Ducts or Overhead? </li></ul></ul><ul><ul><ul><li>Fibre in ducts - Life <25 Years; </li></ul></ul></ul><ul><ul><ul><li>Fibre via overhead - Life <10 Years. </li></ul></ul></ul><ul><ul><li>Re-use existing “Open-Access” infrastructure : </li></ul></ul><ul><ul><ul><li>How far do these infrastructures penetrate locally? </li></ul></ul></ul><ul><ul><ul><li>Can Sub-Loop Unbundling help? FTTC+last FTTP drop. </li></ul></ul></ul><ul><ul><li>Potential to ‘collaborate’ with private utility organizations to: </li></ul></ul><ul><ul><ul><li>Coordinate assets, costs and connectivity; </li></ul></ul></ul><ul><ul><ul><li>Use properly designed ducts infrastructure to maintain future Open-Access capability. </li></ul></ul></ul>Distribution  1 ,  2 ,  3 Cabinet or Buried Box Splitter  1 ,  2 ,  3  1 ,  2 ,  3 Cabinet or Buried Box Splitter <10Km <10Km <10Km) <20Km)
  8. 8. The Access Network <ul><ul><li>Ducts or Overhead? </li></ul></ul><ul><ul><ul><li>As before. </li></ul></ul></ul><ul><ul><li>Where to locate equipment? </li></ul></ul><ul><ul><ul><li>PON Splitters: Street cabinets, buried box, LAN room? </li></ul></ul></ul><ul><ul><ul><li>Ethernet: Needs power: Street cabinet or LAN room? </li></ul></ul></ul><ul><ul><ul><li>Each deployment is different, no “one-size-fits-all” solution. </li></ul></ul></ul><ul><ul><li>Properly designed duct infrastructure to maintain future ‘Open-Access’ capability; </li></ul></ul><ul><ul><li>Section 106 Rules can help. </li></ul></ul>Access Business Park Splitter  1  2 Local Office or Residence ONT ONT LAN Rooms  1 ,  2 ,  3  1 ONT Splitter
  9. 9. Financial Modelling <ul><li>Revenue modelling </li></ul><ul><ul><li>Economic analysis (Funding Models, RoI); </li></ul></ul><ul><ul><li>Customer profiling; </li></ul></ul><ul><ul><li>Service mixes, uptakes and timelines. </li></ul></ul><ul><li>Cost modelling </li></ul><ul><ul><li>Re-use of existing infrastructure?; </li></ul></ul><ul><ul><li>Civil works and street furniture; </li></ul></ul><ul><ul><li>In-building infrastructure; </li></ul></ul><ul><ul><li>Core network including backhaul and ‘Managed Internet’ connectivity; </li></ul></ul><ul><ul><li>Access technologies; </li></ul></ul><ul><ul><li>Ongoing operations, management and maintenance. </li></ul></ul><ul><li>Sensitivity Analysis </li></ul><ul><ul><li>Impact of customer take-up RoI and Investment Case; </li></ul></ul><ul><ul><li>Impact of technology choices & network elements on cost; </li></ul></ul><ul><ul><li>Impact of geographical disparities in economic growth. </li></ul></ul>
