Telstra Research Laboratories

Telstra Research Laboratories is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telstra Research Laboratories rather than just read about it. In short: Telstra Research Laboratories (TRL) was a leading telecommunications research and development centre in Australia up until its closure in January 2006. Shortly before its closure it employed several hundred people including engineers, scientists, psychologists and other technical staff spread over several locations including Melbourne, Sydney and Launceston.

Key takeaways

Telstra Research Laboratories belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Telstra Research Laboratories to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Telstra Research Laboratories from memory before moving on to harder problems.

Reference excerpt

Telstra Research Laboratories (TRL) was a leading telecommunications research and development centre in Australia up until its closure in January 2006. Shortly before its closure it employed several hundred people including engineers, scientists, psychologists and other technical staff spread over several locations including Melbourne, Sydney and Launceston. The closure of TRL, with retrenchment of about 90% of its staff, was part of a broader restructure of Telstra's Network and Technology group following the announcement in November 2005 of the outcome of a strategic review led by new CEO Sol Trujillo. The new operating model places more emphasis on the reliance on key vendor partners, rather than the traditional in-house expertise that TRL provided to assist Telstra in being an intelligent purchaser of equipment and systems. Whilst in operation the Centre was under the management of Ross Lambi Chief Infrastructure Offer and Brendon Riley CEO of Telstra InfraCo who then reported to Sol Trujillo Telstra’s USA born CEO from 2005 to 2009. Telstra is Australia's dominant telecommunications carrier.

History TRL was originally established as the Research Laboratories of the Postmaster-General's Department (PMG) in 1923. The Research Laboratories continued as PMG, became Telecom Australia and later became Telstra, and was responsible for the development of several key technologies. Notable achievements included: a part in the development of radar for WW2; the first fax service in Australia; the first public TV broadcast in Australia; developing termite-resistant cabling; assisting with the development of the bionic ear and the cochlear ear implant; developing the optical fibre cold clamp; and building the first system to route calls to a destination depending on the caller's location (One3).

Worked examples

Example 1 — a first encounter with Telstra Research Laboratories

Start with the simplest possible case. Write down what Telstra Research Laboratories claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telstra Research Laboratories before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telstra Research Laboratories ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telstra Research Laboratories

In research: Telstra Research Laboratories appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telstra Research Laboratories in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telstra Research Laboratories is common in secondary-school and first-year university syllabi. It links to neighbouring topics Australian company stubs, Research institutes in Australia, Telecommunications company stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Telstra Research Laboratories outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
