25 years of network access technologies: from voice to internet; the changing face of telecommunications

Abstract

This work contributes to knowledge in the field of semiconductor system architectures, circuit design and implementation, and communications protocols.
The work starts by describing the challenges of interfacing legacy analogue subscriber loops to an electronic circuit contained within the Central Office (Telephone Exchange) building. It then moves on to describe the globalisation of the telecom network, the demand for software programmable devices to enable system customisation cost effectively, and the creation of circuit and system blocks to realise this.
The work culminates in the application challenges of developing a wireless RF front end, including antenna, for an Ultra Wideband communications systems applications.
This thesis illustrates how higher levels of integration over the period of 1981 to 2010 have influenced the realisation of complex system level products, particularly analogue signal processing capabilities for communications applications. There have been many publications illustrating the impact of technology advancement from an economic or technology perspective. The thesis shows how technology advancement has impacted the physical realisation of semiconductor products over the period, at system, circuit, and physical implementation levels.
