John Costa’s 35 Years of Contributions to this Telecommunications Journal

John Costa has retired from this Journal’s Board of Editors, after 35 years of active contribution. From 1990 to 1992, he was Executive Editor (and Editor-in-Chief), producing eight issues of the Telecommunication Journal of Australia (TJA), the name of this Journal up until 2013. Just as significant were the many subsequent issues of the Journal for which he was Guest Editor, from 1994 onwards. TJA evolved first into the Australian Journal of Telecommunications and the Digital Economy (AJTDE: 2013–2018) and subsequently the more deliberately international Journal of Telecommunications and the Digital Economy (JTDE: 2019– ). As an ongoing and popular member of the Editorial Advisory Board, John was noted for his skill in commissioning new papers from distinguished overseas authors, as well as the impetus he gave the Journal in its coverage of new forms of satellite and terrestrial radio communications.

Elizabeth (Liz) Dyneley Fell, 1940-2020

Liz Fell (7 March 1940 to 13 August 2020), a freelance journalist, was elected a Distinguished Fellow of the Telecommunication Society of Australia in 2003 for her notable and enduring contributions to Australian telecommunications. Amongst others, she carried out brilliant interviews over twenty years (1994-2013) for the Telecommunications Journal of Australia. This article celebrates her notable contributions to Australian telecommunications, and includes references to two of her most famous interviews, with Malcolm Turnbull MP in 2011 and with the Hon. James (Jim) Spigelman AC, Chairman of the ABC, in 2013.

A new Feature Reduction Algorithm Based on Fuzzy Rough Relation for the Multi-label Classification

The paper aims to improve the multi-label classification performance using the feature reduction technique. According to the determination of the dependency among features based on fuzzy rough relation, features with the highest dependency score will be retained in the reduction set. The set is subsequently applied to enhance the performance of the multi-label classifier. We investigate the effectiveness of the proposed model againts the baseline via time complexity.
 Keywords: 
 Fuzzy rough relation, label-specific feature, feature reduction set

The Victorian Time Signal Service

A 1945 technical paper from the Telecommunications Journal of Australia is revisited that describes the timing and signalling equipment used at the Melbourne Observatory between 1853 and 1945. The equipment was used to provide the Victorian Time Signal Service for over ninety years.

Stepping down and handing over

Some departing words from the Journal's Managing Editor in stepping down from the role of Editor-in-Chief of the Telecommunications Journal of Australia and its successor, the Australian Journal of Telecommunications and the Digital Economy, after 21 years in the job.

The NBN Futures Project

Over the past 20 years the provision of broadband services in Australia has become a matter of contention. The National Broadband Network (NBN) and longer-term plans for the way in which it will be structured and operate into the future have been caught up in this. The potential sale by the government of NBN Co, the developer of the NBN, in the next few years has brought greater urgency to considering the longer-term future of the NBN.
 An NBN Futures Project, whose aims are explained in this article, is promoting public and policy discussion through TelSoc (the Telecommunications Association) on the NBN and its future, with the aim of building consensus and common ground as a basis for developing public policy for the future. TelSoc’s role is not to advocate particular policy positions, but to provide media and forums for ensuring that critical analysis and discussion does occur and is shared as widely as possible. The Project promotes articles in the Journal of Telecommunications and the Digital Economy, together with forums, talks and other events.
 This article describes the NBN Futures Project and how it envisages that it will make a difference.

A new Journal for telecommunications with an added purpose

The Australian Journal of Telecommunications and the Digital Economy (ajTDE) is the reincarnation of the Telecommunications Journal of Australia (TJA), under the guidance of essentially the same Editorial Board – give and take a few distinguished members – who had moved the traditional ‘print and post’ version of TJA (published since June 1935) to its exclusively online version (from November 2007 to June 2013).

Peter Darling 1947-2013 A brief commemoration of a gifted writer of tutorial articles on modern telecommunications

This historic first issue of the Australian Journal of Telecommunications and the Digital Economy is dedicated to Peter Darling, one of its founding editors, who passed away on 2 October 2013. Peter was a prodigious contributor to the former Telecommunications Journal of Australia (TJA). He was famous for his gifts in writing accessible tutorial articles on quite complex new developments in telecommunications technology and regulation.
 This short commemorative article references nine papers that Peter authored in TJA from 2002 to 2013, and an extended interview he gave TJA’s Liz Fell in the year 2000.

An Introduction to Telecommunications Policy in Canada

This paper provides an introduction to telecommunications policy in Canada, outlining the regulatory and legislative environment governing the provision of telecommunications services in the country and describing basic characteristics of its market for retail telecommunications services. It was written in 2017 as one in a series of papers describing international telecommunications policies and markets published in the Australian Journal of Telecommunications and the Digital Economy in 2016 and 2017. The discussion focuses on broad trends and major players and identifies key regulations and policies in place in 2017, with information drawn primarily from regulatory and policy documents. The paper does not offer an exhaustive description of all telecommunications policy issues, markets and providers in Canada.

Historical paper: The 2004 Proposal for the Structural Separation of Telstra

A comment by Australian Prime Minister Malcolm Turnbull on 23 October 2017 has re-awakened interest in the possibility that lay open in 2004 for the then Coalition government, of which Mr Turnbull was a member, to have preceded New Zealand in reaping the benefits of structural separation of the incumbent carrier. The paper “Revisiting the Stuctural Separation of Telstra”, published in the Spring 2004 issue of the Telecommunications Journal of Australia and republished below, provided not just the policy rationale for structural separation, but also detailed how it could have been achieved.

A Time For Renewal

The Telecommunications Association has commenced the second phase of the renewal process that started in 2013. As part of the first phase of this renewal process a key decision was to relaunch the Telecommunications Journal of Australia as the Australian Journal of Telecommunications and the Digital Economy. In addition to the Journal, the Telecommunications Association holds the Henry Sutton and Charles Todd Orations each year in Melb0urne and Sydney respectively. As the second phase progresses, the Telecommunications Association will launch a new brand, update the Association’s website and host the first of what should become an annual two-day telecommunications forum. The first event is to be held in Melbourne in November. For the Journal, key milestones have now been achieved, including being added to the SCOPUS list of indexed Journals and the Australian Research Council’s Excellence in Research for Australia, which is the national research evaluation framework.
