How to tame densification of wireless networks with SDN/NFV

  1. 1. How to tame densification of wireless networks using SDN/NFV Pisa Internet Festival, 10/10/13

  4. 4. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 4 The Big Problem Traffic Revenues Data eraVoice era Telecom operator 
  5. 5. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 5 Picture of the Big Problem Debut of Pope Benedict Debut of Pope Francis
  6. 6. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 6 Need more wireless capacity? • Today’s radio access technology is (largely!) overprovisioned: – IEEE 802.11n: easily 100 Mb/s, can be 300 Mb/s – HSPA+: up to 84 Mb/s – LTE: up to 300 Mb/s • Let’s not even mention LTE-A!
  7. 7. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 7 So what do we need? • Add more and more base stations, esp. where capacity is needed: – Crowded public spaces – Residential buildings, offices – Events, fairs – … What we get
  8. 8. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 8 Densification of wireless access networks From macro-cell only
  9. 9. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 9 Densification of wireless access networks From macro-cell only to pico-cells
  10. 10. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 10 Densification of wireless access networks From macro-cell only to pico-cells to small-cells
  11. 11. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 11 Summary • We have demands from market/users today • We have technology supporting those demands today • Unfortunately we just can’t continue to deploy new base stations because we have issues: 1. high CAPEX/OPEX €€€ 2. interference 3. backhaul 4. signalling

  13. 13. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 13 Project overview • Connectivity management for energy optimised wireless dense networks – Start: 1/1/13 – End: 30/6/15 – Total cost: 4,460 k€ – Total funding: 2,978 k€ – Total effort: 443 PM
  14. 14. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 14 Goal To enable sustainable deployment of very dense and heterogeneous wireless networks sustainable = cost effective + energy efficient very dense = 1000x compared to current density (in users/sqm vs. users/BS) heterogeneous = + diverse range (macro vs. pico vs. femto) + diverse technologies (LTE vs. WiFi) + diverse deployments (planned vs. unplanned) + diverse backhaul types (optical vs. wireless)
  15. 15. 10/10/2013 – Pisa Internet Festival claudio.cicconetti@intecs.it 15 How is this done?
