5G integration of Mobile and Wireless Networks, Business and SIM


Published on

While LTE (which some people call 4G mobile network) is on the way of getting deployed, discussions are ongoing towards 5G mobile communications.
The talk states that "a new radio interface" is a potential challenge, but integration aspects of heterogeneous networks are far more important. These aspects include seamless authentication across networks and "the business of heterogeneous networks". One focus is on the future SIM as an enabling technology, addressing the seamless access. The second item is on business aspects - "is there a business?" in heterogeneous networks.

5G integration of Mobile and Wireless Networks, Business and SIM

  1. 1. Center for Wireless Innovation Norway cwin.no CWI Norway CTIF - CWI workshop, Aalborg, Oct 2009 5G communication – a user-centric vision driving integration? Josef Noll Professor Senior Advisor University of Oslo/UNIK Movation AS josef@unik.no josef.noll@movation.no
  2. 2. Outline  From 1G to B3G, the service aspect  Drivers for higher bandwidth in 5G communications – Seamless authentication – 5G radio  Future SIM – Authentication centre – who owns the SIM card  Heterogeneous Radio – Shannon - the bandwidth dilemma – Cooperative business models  “While waiting for the future SIM” – Alternative Solutions 5G communications Oct 2009, Josef Noll 2
  3. 3. Service development on Mobile Phones Personalised broadband B3G: wireless services 3G: Multimedia communication 2G: Mobile telephony, SMS, FAX, Data 1G: Mobile telephony 1970 1980 1990 2000 2010 Original: B3G study, Jan 2001 Josef Noll, Sep 2004 Enabling Communication 3
  4. 4. B3G - the service aspect  Beyond 3G = Personalised Broadband Wireless Services  Personalised – Limited to CPA services – “login/password” is a security threat and a hinder for seamless personalisation  Broadband – partly satisfied for LTE (4G radio) and home WLAN (802.11n)  Wireless - yes  Services - the real drivers for 4G and 5G radio – iPhone (AppStore), Android – Widgets, Applets  5G - more bandwidth? 5G communications Oct 2009, Josef Noll 4

  6. 6. 5G business entities  Media, Content  Banks, Service providers provider  Telecom, Corporate, Home Service Payment aggregator provider • Service aggregator • Convenient interfaces • Ease of use Identity and personalisation provider • Identity and personalisation Authentication Customer provider care and Access • Convenience provider • Trust 5G communications Oct 2009, Josef Noll 6
  7. 7. 5G business - Content content and services provider  Novel applications will require higher bandwidth  Higher bandwidth will foster new applications  “There has always been something filling up bandwidth”  Examples: – Movie download – Sync operations – Animated reality, virtual (real) world, – Multiple simultaneous access  “Willingness to pay is not related to bandwidth” 5G communications Oct 2009, Josef Noll 7
  8. 8. 5G access - business Authentication considerations and Access provider  Access challenge: More bandwidth with less revenue Capacity increase  The radio dilemma related to 900 MHz capacity 7 relative Capacity increase – frequency ↑, bandwidth ↑ – frequency ↑, range ↓ 5 – outdoor to indoor outdoor 2 outdoor to indoor  The business dilemma 0 800 1800 1900 2400 3500 5200 – 5G access is expensive frequency [MHz] (range) – changing access means loosing revenue 5G communications Oct 2009, Josef Noll 8
  9. 9. 5G aspects  Bandwidth requirements come from other form factors (notebook, portable 3D cinema)  Assuming standardisation of application language – convertable widgets – web technologies (SAWSDL, html7) Seamless login  Seamless authentication – “My driver license on the information road”  “Indoor coverage can’t be satisfied through outdoor base stations” what are the drivers? – cooperating networks 5G communications Oct 2009, Josef Noll 9

  14. 14. Drivers for collaborative access Radio access networks  Heterogenous networks – Different entities – reduced revenue – “Collaborative Business Model” for seamless wireless access  The user as the driver – reduced costs – reduced electromagnetic radiation  Enabler – National authorities – EU commission – 5G communications Oct 2009, Josef Noll 14
