Towards ‘liquid bandwidth’

clearly
EU-Japan conferenceClearly …
  • … there is a need for massively wireless data access networks:
    • NL-mobile data usage in Q4 2012: 6.75 Pbyte (in Q4 2011: 4.3 Pbyte)
    • Interesting regions: now – theconference centres (e.g. RAI)are much more interesting compared to airplanes (fibre optics + ultra low power wireless USB to your chair?), trains (idem).
  • So: what drives wireless?

General drivers:

  • More speed (1G, 2G, 3G, 4G, …)
  • More spectral efficiency
    • Growth data to be transported >> available spectrum
    • Densification, architectural changes
  • Battling interference
    • higher frequencies, multi-hop
  • Diversity in use
    • More efficient ways of sharing spectrum
    • Spectrum harvesting, cognitive radio, spectrum etiquette

What drives wireless?

with this in mind what makes massively localised work
EU-Japan conferenceWith this in mind – what makes “massively localised” work?

RULE 1:

  • ‘A’ depends on context, situation, density of nodes – should be adapted!

RULE 2:

  • Find shortest path to ‘gateway’ on fixed network

Find the path of minimal ‘resistance’ – like liquid: LIQUID BANDWIDTH

what drives interference and adaptability
EU-Japan conferenceWhat drives ‘interference’ and ‘adaptability’?
  • A combination of power control, ‘the right frequency’, multi-hop, space division, localised intelligence
    • mm-waves: high propagation loss, so nature works for you
    • multi-hop: minimizing interfered region
      • Slightly more advanced: listening is more expensive compared to talking, so there will be a lower limit.
    • space division: from tri-sector to (optical) pencil beam *)
    • ‘intelligence per mm3’ is scaling faster than communication speed

*) Research by e.g. prof A.M.J. Koonen, TU Eindhoven

don t forget it s all about timing
EU-Japan conference“Don’t forget: it’s all about timing …”
  • If trend in wireless is to provide more bps/m3 andnetworks get more dense:
    • Wired infra becomes enabler and root of success-ful roll-out of next-generation wireless infra

conclusion
EU-Japan conferenceConclusion
  • Massively localized access networks are driven by cognitive nodes in an ad-hoc network – looking for a ‘minimal resistance’ way to connect to the ‘wired backbone’
    • Fibre / optical backbone as the ICT-nervous system
  • Key enablers are:
    • mm-wave technology, cognitive routing techniques like OpenFlow, advanced space division (e.g. pencil beam), and the generic increase of ‘intelligence per mm3
  • First deployment is expected in large and densely populated conference centres
