          How Fast Can You Go?

 Over the last 100 years the type
  of information that we can transmit
  electronically has not changed
 Only the transmission speed has increased
 The typical high-speed Internet connection
  is 300,000 times faster then Morse Code

     Emerging Technologies

      Today’s Common Technologies

 Dial Up Connection – Uses existing
  telephone lines and modem
  (Speed: 56,000 bps)
 T1 Lines – High-speed digital
  telecommunications line (Speed: 1,544,000
  bps or 1.54 Mbps)

       Emerging Technologies

        Tomorrow’s Technology Today
 Digital Subscriber Line (DSL)
     Can provide connection speeds of
      512 Kbps to 1.54 Mbps
     Uses existing telephone system but employs
      new technology
     COST: $49.95 per month ( 2 yr.)
     Limited availability – future unclear   CIESE

        Emerging Technologies

        Tomorrow’s Technology Today
 Cable Modem – Uses existing cable TV
  system to deliver high speed Internet access
     Connection speeds of 1.5 Mbps
     COST: $40 per month
     Becomes slow with too many users

        Emerging Technologies

        Tomorrow’s Technology Today
 Wireless Computing – Wireless Local Area
  Networks (LANs) and Wireless modems are
  now available
     Wireless LAN – Radio
      frequency-based (Speeds: 11 Mbps)
     Cover only small local area

       Emerging Technologies

      Tomorrow’s Technology Today
   Wireless modems – Radio or cellular (CDPD)
    frequency based
   Coverage is limited (Speed 19.2 kbps
    – 28.8 kbps)
   COST: $300 - $1000 for modem card
    and $45 per month
   Some are going out of business          CIESE

     Emerging Applications

        What Does This All Mean?
 Multimedia Internet-based applications
 Video Conferencing via the web and wireless
  devices (e.g. cell phone, Palms)
 Application Service Providers (ASP)
 “Thin Client” Applications
 Remote access to scientific instrumentation
