Observations and Conclusions from a Three Year Digital Radio Field Experiment in Australia

For the purpose of investigating the performance of digital radio systems, Telecom Australia established and conducted over a three year period (1982-1984), a 140 Mbit/s 16 QAM digital radio field experiment. In parallel with this experiment, analytical work was undertaken to develop an "outage prediction method" to assist with route design. This paper presents the observations and conclusions drawn from this work. Emphasis is placed on the aspects which relate to system design. We show that for digital radio outage prediction, a radio path can be characterized for multipath fading by the probability of occurrence of multipath fading and the mean echo delay, while the radio equipment can be characterized by a set of normalized parameters. The performance improvements achieved through the use of adaptive equalization and space-diversity are highlighted. Finally, we present a methodology for considering the performance of digital radio systems in the presence of interference and thermal noise, and present results for system performance with adjacent channel interference.

Minors and the Satellite

The Australian Satellite Users Association (AUSSAT, later SATUsers)1 was formed in 1981 by a number of concerned individuals who believed that planning for a domestic satellite communications system was proceeding with scant regard for the interests of minor, non-profit, users. While much had been said about the potential benefits of the proposed system for the isolated and disadvantaged, there was every indication that its technical specifications, tariff schedules and operating conventions would be heavily influenced by the demands of television networks and by Telecom Australia's determination to protect existing terrestrial markets.

Aussat and Business Management

With the launch of the domestic satellite system in the last quarter of 1985, the monopoly enjoyed by Telecom Australia in the supply of long haul telecommunications carriage ended. It ended in a gentle way since the alternative carrier, aussat Pry Ltd is 75% owned by me Commonwealth and 25% owned by Telecom.

Teleconferencing Research at Telecom Australia

The benefits and advantages offered by teleconferencing and new research and development in the field are discussed. The Telecom Australia Research Laboratories aim to establish how meetings are affected by different teleconferencing facilities, and to present the results in a form that is useful in assisting designers and users.

History of Telecommunications in Australia

The following chronology of the development of telecommunications in Australia is excerpted from a series of illustrated posters produced by Telecom Australia and available from the Public Relations branch of Telecom in each capital city.

Telecommunications as ecosystem: An Australian case study

In describing methods of analysing and evaluating alternative policy options of large systems, like the Australian Telecommunications Commission, this article proposes a set of criteria to test the policy options of Telecom Australia. The criteria are developed through three levels of enquiry. The rational enquiry describes the objective characteristics of the system; the mythological enquiry describes that set of beliefs which justifies the system's organization; and the ecological enquiry evaluates the adaptability of the system. This article concludes that re-evaluation at the mythological level is necessary for the successful continuation of Telecom Australia.
