  1. Towards ‘liquid bandwidth’ Prof. dr. Erik Fledderus TNO | Managing director Information Society TU/e | Professor Cognitive Wireless Networks

  2. EU-Japan conference Clearly … • … 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?

  3. EU-Japan conference What drives wireless?

  4. EU-Japan conference More speed What drives wireless? Edholm’s law

  5. EU-Japan conference More spectral efficiency (bits / s / Hz / m3) What drives wireless?

  6. EU-Japan conference What drives wireless? Battling interference

  7. EU-Japan conference What drives wireless? Diversity inuse

  8. EU-Japan conference 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?

  9. EU-Japan conference With 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

  10. EU-Japan conference What 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

  11. 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 Ray Kurzweil From wall-sockets to ambient connectivity … Source: ZTE, 2012

  12. EU-Japan conference Conclusion • 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
