Every Transport Technology

telecommunications industry constant innovation
Telecommunications Industry: Constant Innovation

VoIP and Converged Communications

Wireless to WiMAX/4G/LTE

Wireline to Wireless

Copper to Fiber

Change comes from disruption. And disruption is constant!

Analog to Digital

  • Transition from Fixed to Mobile
    • Growth of fixed services slowing, turning negative
    • Mobile phone growth continues but levelling off due to market saturation

Phone Network

Data Network

  • Transition from Analog to Data
    • On circuit-switched (analog or TDM) voice networks, data is handled by making it look like voice (modems)
    • On packet switched data networks, voice is handled by making it look like data (VoIP)
discontinuities and convergence
Discontinuities and Convergence
  • … so we enlarged them to just about the right size.

Once we just had a telephone on our desks.

Then we added a computer mainframe terminal,

but replaced that with a personal computer …

… which became portable (laptop), …

… we added wireless networking including voice,

but we shrunk them a little too much …

Where Should Intelligence Reside?

SG 13 Work on “Future Networks”

Some Thoughts on the Future

intelligence was centralized but is it in the right place
Intelligence was centralized, but is it in the right place?
  • We began with human operators “inside the network” handling switching and services for “hard-wired” subscribers, …
  • ... “progressed” to analog mechanical circuit switching (SxS), ...
  • ... refined it with stored program control (#5 XBar, SP1), ...
we continued with the assumption that terminals were dumb
We continued with the assumption that terminals were “dumb” …
  • We converted from analog to digital transmission and switching.
  • We centralized network intelligence into with replicated islands of intelligence enabled by common channel signalling.
but isdn and mobility changed everything
… but ISDN and Mobilitychanged everything!
  • Suddenly terminals had to be able to do a great deal more:
    • A functional ISDN terminal is a de facto 2 line exchange!
  • Cellular networks added a new dimension to what terminals had to do:
    • Mobility!



  • We’ve gone from one extreme to the other:
    • Start: all intelligence in the network and none at the edges “dumb” terminals
    • Advances in technology enabled intelligence to migrate to terminals connected to a “dumb” network
  • Neither end of the pendulum swing is ideal …

Some Key Developments
  • Computing technology advances enable more powerful, faster computers
  • Today’s personal computer is yesterday’s super computer
  • Technology applied in handsets: as powerful as desktop PCs a few years ago

Open (incl. Policy)


Change is constant: adapt and adopt!




  • Mega trends aredefining a new era:
    • Hyper-connectivity
    • Network-awareapplications andapplications-awarenetworks
    • True Broadband
  • Technology is all about enabling users to do what they want to do!





The world is rapidly becoming Hyperconnected!


Anything that can be usefully connected will be connected

communications enabled applications
Communications-Enabled Applications
  • Reinvention of services and applications to support new levels of network-aware intelligence and an intuitive interaction experience
    • Achieve through advanced technology frameworks such as IMS and Services Oriented Architecture (SOA)
true broadband
True Broadband
  • The communications experience is so seamless that users no longer have to consider which technology is being used to make a connection.
  • Users simply communicate, anywhere, anytime from whichever device is most convenient. Most importantly, the broadband experience becomes so economical that the range of uses exceeds any experience of the past.
