Introduction

With more that 100 million broadband users the underlying access technology of the internet is changing. This enables a new set of applications, new business models and the revisiting of old business models. People today spend four times as much time on the internet as in the heydays of 2000. Very different conceptions of broadband access. Several of the cable and television and telecoms companies see broadband as distribution means for, television, similar to the airwaves, but in this case allowing for pay for view access of the content, therefore would like high downstream speeds and low upstream speed. Internet companies (Google, Yahoo, Amazon) see this as interactive infrastructure and therefore want more synchronous (i.e. equal up and downstream speeds). The current debate of net neutrality, is the start of the coming painful convergence of television, music and telephony on the internet and IP as a base architecture. Useful places to look are:

Research Questions:

We consider the following questions crucial in understanding the broadband technology and it's future:

1.

Basic:

* What is broadband?

The term applies to networks having bandwidths significantly greater than that found in telephony networks. Broadband systems are capable of carrying a large number of moving images or a vast quantity of data simultaneously. Broadband techniques usually depend on coaxial or optical cable.

what are the advantages of broadband?

Fast, always on line, cheaper than dial-up, enables bigger files to be downloaded (video, music)

* what are the techniques available?

The breakdown of broadband technologies in December 2005 is as follows:

    o DSL: 62%
    o Cable modem: 31%
    o Other technologies (e.g. satellite, fiber and fixed wireless) : 7%

Current:

* what is the current broadband penetration?

The current broadband penetration in OECD countries (December 2005) is 13.6% of the population. The growth rate of the penetration was 15% in 2005. The top 4 countries are Iceland, Korea, The Netherlands and Denmark with penetration rates over 25%. In real number, the country with the largest amount of subscriber is the USA. The lowest penetration rate is granted to Greece with 1.4%. The EU 15 averages at 14.2% penetration.

The growth of broadband penetration amongst OECD countries is supported by the different governments and enjoys exponential growth:

     2001  2002  2003  2004  2005

OECD 2.9 4.9 7.3 10.2 13.6

EU15 1.6 3.4 5.9 9.7 14.2

* who are the main players?

In each of the separate countries, the national telecom provider is the main player for broadband diffusion, especially for DSL connections. Nevertheless, with the increased penetration of other techniques such as cable, fiber optic, satellite and wireless, new players come into play, often offering broadband internet in a bundle of products (Satellite/ cable TV, telecoms, etc.)

* what are the main bottlenecks to broadband diffusion?

Regional disparities, Transition to ‘real’ broadband, Security, Energy Consumption (an internet firewall consumes more energy per household than a clothes dryer),
