Some Technology Trends

• Internet Protocol (IP) technologies as
  strategic element in design, development and use
  of telecoms networks
• Unification and interoperability of IP-based and
  PSTN network services/applications
• Gateway devices that can exchange voice, video,
  facsimile and data traffic between PSTN and IP
  networks emerging
• Move towards holy grail of voice and data
  integration

3
More Trends

• Popularity of wireless networks and mobile data
  services
• We will see Post-PC second wave of Internet
  growth in personal communicator appliances
• Jeff Hawkins inventor of the Palm Pilot
• The future of Internet access is mobile Internet
  access
• 2.5 3G (IMT-2000) networks will enable this
  revolution

ITUs IMT-2000

• Features of IMT-2000 Capability Set 1 include
• Support of packet data services (e.g., IP)
• Data rates 384 Kbps to 2 Mbit/s
• Quality of service negotiation
• Asymmetric or symmetric upstream/downstream bit
  rates
• Global roaming capability
• First deployed in Japan in early 2001 then Europe
  then Americas

Communicator of Tomorrow

• Tell it where you are and you can find what
  youre looking for
• With operators or GPS location service, you
  dont even need to tell it where you are
• We will constantly synch with data about our
  environment

Thank you for your review!

Traffic Jams

• Internet is currently a best-effort network
• Holy grail requires quality of service
  applications (e.g., PSTN-like voice, video) mixed
  with best-effort ones (e.g., email, WWW)
• Differentiated services require
• guanteed quality of service levels and
  differentiated bandwidth usage
• new pricing accounting models to account for
  different traffic value flows
• new models of interconnection roaming
  agreements

Mobile Internet dilemmas

• In the Internet world
• Access is generally unmetered, flat-rate
• E-mail is perceived to be a free application
• Content providers gain revenue principally
  through advertising or subscription
• In the mobile world
• Access is generally metered, per-minute
• Voice mail and messaging are charged by air-time
• Content providers share airtime revenues
• In a mobile Internet world
• Which business model takes precedence?
• Who does the billing?
• How are interconnect revenues split?
