Evolution of Mobile Networks - Impact and Possibilities for Future Services

6,331 views

Published on

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.

Evolution of Mobile Networks - Impact and Possibilities for Future Services

  1. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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
