This paper was first presented at an Institution of Engineering and Technology seminar held at Savoy Place in London on Monday 24th September 2012 celebrating 175 years of telecommunications. It was subsequently published in 2012 within a special issue of the Journal of the Institute of Telecommunications Professionals (Volume 6, Part 4, Pages 46-49) and is made available here with their kind permission.
