Broadband Technology

Tuesday 20 March 2007


Anglia Ruskin University, Chelmsford

Elspeth MacFadyen, BT


The talk will explain BT’s approach to enhancing the capability of fixed network broadband, within a frame of reference including technology and economics. Pressure for more bandwidth is growing rapidly and BT must respond in a way that meets the needs of customers and makes business sense. It is BT's ambition to ensure that customers get the service level their applications require, from access to backhaul and beyond. BT has an ongoing research and standards programme in DSL, and copper and optical transmission. Fibre architectures FTTP and FTTC with ADSL2+ sourced in the cabinet have been trialled in 2005/6. A trial of cabinet-sourced VDSL2 is expected to start before the end of 2006, subject to availability of line-cards from manufacturers.

Elspeth works in BT's Group Chief Technology Office, where she directs Group activities on key access technology strategy questions.
