This presentation discusses the evolution of mobile networks and the resulting potential for future devices and applications. Drivers are, for example, LTE, HSPA+, higher speeds, more bandwidth, fixed-mobile convergence, DSL and cable access in an overall network strategy, cloud computing, connected home services, always best connected, social networks and privacy.

  • 1. Oxford University CPD Future Technology Conference April 2009 Evolution of Mobile Networks Impact and Possibilities for Future Services Martin Sauter 1 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 2. Who Am I Working on wireless projects for a network • infrastructure vendor (Wireless) Network Researcher and Blogger • Book Author • 2 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 3. Future Services By Whom? Internet based companies (Google, Skype, • Yahoo, startups, etc.) Their business model: Idea, trial and error, free at • the beginning, later funded by advertising and premium services Network Operators • Their business model: Pay for services from day • one → Interop. and getting a critical mass is difficult This presentation looks at how Network Operators can benefit from the Network Evolution 3 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 4. Trend 1: Wireless Networks Are Evolving UMTS → HSPA → HSPA+ • LTE is at the doorstep, promises even higher speeds • Lots of improvements to achieve higher speeds like • higher order modulation and MIMO. Digital Dividend for Broadband Everywhere • The good news: Higher top speeds will help us for • some time to escape bandwidth bottlenecks. The bad news: Super high speeds only in selected • places! 4 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 5. Higher Speeds But Not Everywhere Ericsson Review article shows maximum speed depending on location. http://tinyurl.com/dk6c2p (not included due to copyright reasons but available via this link, see Figure 2) 5 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 6. Cellular Capacity Today and Tomorrow 3G Network Capacity Today: ~30 MBit/s per km² • (4 UMTS networks, one BTS per operator per km², 3 sectors, single carrier) Based on 70 MB of daily data traffic (~2 GB/month) that's • good for 800 users per km² Potential 3G Capacity Tomorrow: ~ 500 MBit/s per km² • (use of full capacity in 900, 1800, 2100 and 2600 Mhz with HSPA and LTE) → But: Who can predict how many people will use the system in the future and how traffic develops? * If you are interested in the details for the numbers, please contact me via http://www.wirelessmoves.com 6 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 7. Trend 2: Fixed Line Advances ADSL speeds are increasing • ADSL2+ available in many • locations VDSL now being deployed: • But: Expensive! Fiber to the Home • → Almost infinite capacity and A VDSL cabinet reachability. But: Even more expensive! And on top: It's fixed line but most people don't use it with a cable → Wi-Fi is also wireless! 7 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 8. Trend 3: Fixed – Wireless Reintegration Wireless Operators are buying fixed line assets • again. With the Internet, operators have finally • understood that it makes no sense anymore to offer fixed and mobile services separately as most users want both! → Usability break! Complete reversal over earlier trend! • 8 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 9. Trend 4: Femtocells - Making use of Fixed Line Assets Femtos will be integrated • into a single DSL-modem / Wi-Fi / Picocell package. The first obvious use: It's • good for offloading a significant amount of traffic from the macro network.

  • 10. Putting all 4 Trends together leads to: Connected Home Services „Mobile“ devices (phones, smartphones, mp3 • players, cameras) interact with the „fixed“ devices in the home network (PC, Network Attached Storage containing pictures, videos, and other private information) Access to „fixed devices“ and data stored on them • also while being outside the home network via the cellular network over an encrypted link. 10 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 11. Connected Home Services Femtos vs. Wi-Fi Femtos great for network operators • Wi-Fi great for Internet companies • Who will win? • Maybe both should win? • Peaceful coexistence. • Always best connected (best as in fastest, cheapest, • most convenient). Possible with both femtos and Wi-Fi. → Intelligent Software 11 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 12. Trend 5: Cloud Computing What is it, who likes it and why? → Computing resources • in the network and storing data (calendar, address book, files, etc.) somewhere in the Internet. Many interesting possibilities, BUT: storing private data • on the Internet is not to everyone's liking → inherent privacy and security issues, wanted and unwanted. → Connected Home Networks offer an alternative to storage in the cloud to protect data and privacy! 12 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
  • 13. Summary Trend 1: Wireless Network Evolution • Trend 2: Fixed Network Evolution • Trend 3: Fixed - Wireless Re-Integration • Trend 4: Femtos + Wi-Fi • → These trends pave the way for Connected Home Services Trend 5: Cloud Computing • Anti-Trend 5: From the Cloud to the Home • → Great possibilities for network operators in the future! 13 Martin Sauter - www.wirelessmoves.com - Future Technologies Conference - Oxford University CPD - April 2009
