Today Tomorrow Yesterday • Mobile networks • Voice Services Internet Access • SMS, MMS, Data Transmission • Fixed networks • Voice Services Internet Access TV • Mobile networks • Voice services • Internet access • Videoconferencing • TV • Fixed networks • Voice Services • Internet Access • TV,HDTV, VOD Mobile networks Voice Services Fixed networks Voice Services

  3. Access networks Fixed networksxDSL VDSL2Opticalnetworks(PON) Mobile networksGSM UMTSWIMAX + WiFiCDMA

  4. Mobile networks • Pros • Wide area coverage • Mobility of subscribers • Cons • Limited RF resources • Shared bandwidth Fixed networks • Pros • Dedicated bandwidth • Provision of multimedia services • Cons • High CapEx • Lack of mobility

  5. Fixed networks - evolution • Optical fibrecables • Built-in backbone networks • FTTC • FTTB • FTTH Pros: unrestricted bandwidth Cons: high network build costs

  6. Mobile networks – trends in development Target Solution = LTEStandard

  7. Mobile networks – integrated network architecture • Implemented technology • Unlimited access • Roaming

  8. WiMAX (802.16-2004) + WiFi (802.11n) • Pros: • Low cost of equipment • Competitive prices • Cons: • Evolving technology • Geographical limitations (e.g.,due to lack of roaming)

  9. WiMAX (802.16-2005) + IMS

  10. Mobile networks - bandwidth

  11. WIMAX or G3.x? • Wimax • The 802.16-2004 release • Market niches – for mobile and fixed telcos • Services offered for rural areas • The 802.16-2005 release • Depending on launching scale • Mobile network standard – global coverage • Local „islands” – supported by WiFi • G3.x • Service availability limited to major metropolitan centers G.xWIMAX multi-service networks transport networks

  12. Major cost components • G3.x • High network build costs (operator license, RF fees, equipment) • Wimax • Relatively low cost of „islands” – Internet Access • High network build cost– value added services

  13. Fixed networks - bandwidth

  14. Fixed network - VDSL2 • Pros • high transmission speed • Triple Play services (incl. HDTV) • Cons • small-area coverage • problems with using of existing network • investment costs

  15. Fixed network – The range of xDSL/VDSL

  16. Fixed networks withTriple Play service provision

  17. Alternate solutions CATV networks • Fixed network • Shared bandwidth • Geographical restrictions • Competitive to ADSL/VDSL (WIMAX 802.16-2004) Digital TV • Satellite TV • Terrestrial TV (with HDTV, VoD)

  18. What is next ? • Voice (communications, video, messaging) - in charge of mobile networks - fixed and mobile network convergence • Internet - via any transmission media • Multimedia applications - such as HDTV or VoD - in charge of fixed networks
