  • The Future of Information Services and their management Presentation at the KhTURE 12.9.2000 Kalle Lyytinen University of Jyväskylä
  • Future of Information Services
    • Fast change in all computing technologies
    • Networks and distributed computing architectures ubiquitous (internet)
    • Migration of applications, telecommunications and media
    • Creates new information services and service channels
  • The New Digital Environment Technology Market Global connectivity via an open network Global Information Infrastructure Transformation of physical media into digital format Digital Convergence Doubling of digital engine capacity every 18 months Moore’s Law For transmission, presentation, interaction, security Open Standards Tailoring of product/service to unique needs of the customer Mass Customization Value increasingly derived from information content Information Industries High penetration of computers and knowledge to use them Computer Literacy On-demand delivery, whenever, wherever Anytime, Anyplace

  • The Change in Telecommunication Landscape
    • From fixed to wireless
    • From narrow band to broadband
    • From circuit switched to packet switched
  • From Fixed to Wireless
  • Forecast for Mobile Communications in Finland by Finnish Post & Telecom in 1983 150.000 100.000 50.000 0 1971 -75 -80 -85 -90 -95 2000 GSM NMT ARP Total Subscribers Note: Actual number of connections in 1998 was 20 times as many as forecast
  • Case: Finnish experiences - Highest Mobile Communications Penetration in the World % of population February 1999

  • The new wireless technology enablers
    • WAP (Wireless Application Protocol)
    • UMTS (Universal Mobile Telecommunication System) and Media Phones
  • What Is WAP ?
    • The WAP (wireless application protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radioTransceivers, can be used for internet access, including e-mail, the world wide web, Newsgroups, and internet relay chat (IRC).
  • What is WAP (2)
    • WAP specifies means for offering mobile internet services:
    • Vendor independence (open standard)
    • For mobile terminals
    • Assumes slower and lower reliability in connections
  • What is WAP ? (3)
    • Compatibility is ensured:
      • all digital mobile networks including:
      • GSM-900, GSM-1800, GSM-1900 ,CDMA IS-95 TDMA IS-136
      • 3G systems - IMT-2000, UMTS, W-CDMA, Wideband IS-95GSM, DCS, DCMA, WCDMA
      • WWW bases standards and protocols
      • in future UMTS and other 3G will bring only more bandwitdth, but the service level will remain the same (WAP)
  • WAP HTTP Päätelaite WAP-gateway WWW-palvelin
  • Internet Comparison between Internet and WAP Technologies HTML JavaScript HTTP TLS - SSL TCP/IP UDP/IP Wireless Application Protocol Wireless Application Environment (WAE) Session Layer (WSP) Security Layer (WTLS) Transport Layer (WDP) Other Services and Applications Transaction Layer (WTP) SMS USSD CSD IS-136 CDMA CDPD PDC-P Etc..
