  • Hi Josef, Thanks and I would agree to some extent. As mentioned in the slides, apart from underlying technology, we need to look at business models and also regulatory aspects. I think your concern could be addressed mainly there.

  • Hei Sharam,
    again, a very good presentation. Liked your views, excellent knowledge and clear slides.
    The main challenge to my understanding is 'still' the convergence between privat (home, office,...) and public (operator) infrastructure.
    Looking forward to discuss.

Broadband/Mobile Broadband the 4th Utility Blurring boundaries and convergence of telecommunication, information, broadcasting, media and publishing technologies Services grow in multiplicity, diversity and richness of content More powerful and enabled devices - Changes on the shape, size, capability and price Hyper Connectivity- mobile Internet with extreme mobility, ubiquity, personalization, adaptation, video addiction and surprising applications as yet unimagined Ubiquitous ultra broadband high quality and affordable communications essential to the functioning of modern life & society MBB Communication & Service Outlook + Telecommunication at the heart of several industries Transport, Utility, Education, Health & Commerce 4
  5. 5. High capacity pipes with intelligent plumbing that could incorporate sophisticated resource control capability Page 5 Growing Population Hyper Connectivity Limited Resources Hundred-fold increase in network flow brought by mass terminals and mass digital content and hyper connectivity -> thousand-fold increase in traffic flow on mobile networks Mobile data traffic is doubling every year BUT capacity doubles every 10 years Spectrum the blood line of mobile communication, finite resource, scarce & expensive New network topologies, frequency reuse and deployment strategy key to keep up with exponential increase of traffic with limited spectrum availability Communication network to improve in intelligence, flexibility, automation, resilience, efficiency, speed, security, privacy, latency YET lower delivery cost per bit/per sub/per km2 5 MBB Service Outlook – cont.
