Unwired

Unwired 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 Unwired rather than just read about it. In short: Unwired Australia Pty Ltd was an Australian company dedicated to fixed wireless telecommunications network offering carrier grade Internet services. They provided coverage in Melbourne and Sydney.

Key takeaways

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

Reference excerpt

Unwired Australia Pty Ltd was an Australian company dedicated to fixed wireless telecommunications network offering carrier grade Internet services. They provided coverage in Melbourne and Sydney. As of 8 March 2010 Unwired had 52,320 customers and 97 employees. The technology used by Unwired was provided by American manufacturer Navini Networks and Venturi Wireless Solutions. Unwired utilised a wireless network similar to WiMax, using base towers that broadcast a microwave signal, offering speeds of up to 1024 kbit/s. The Unwired network was the first data only network providing Internet services in Australia. Unwired customers used external modems to connect to the wireless network. Unwired technology was portable, but not mobile - the technology does not operate well while the receiver was in motion. The network operated at 3.5 GHz within a spectrum exclusively reserved for use by Unwired. Unwired offered free technical support 7 days a week plus public holidays. Optus bought out Unwired and shut down the Unwired network at midnight on 28 February 2013.

Corporate acquisitions The Seven Network Limited's subsidiary Network Holdings acquired Unwired in 2008 for a reported $127 million. Seven Network Limited owns 50% of the Seven Media Group which owns the Seven Network. At this time Unwired CEO David Spence left the company. Unwired was later consolidated into Seven's wireless broadband division, Vividwireless which was based in Perth. Australia's second largest telecommunications company, Optus, announced in February 2012 that it would buy Vividwireless from its parent Seven Group, for a total cost of $230 million. Optus said this would create a new 4G mobile broadband network in Australia.

Closure Optus shut down the Unwired network at midnight on 28 February 2013 so that the spectrum can be used for its 4G network. Subscribers had to migrate to another internet service provider. Prepaid subscribers were given a refunds on remaining credit and pro-rated refunds on unused data.

Worked examples

Example 1 — a first encounter with Unwired

Start with the simplest possible case. Write down what Unwired 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 Unwired 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 Unwired 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 Unwired

In research: Unwired 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 Unwired 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: Unwired is common in secondary-school and first-year university syllabi. It links to neighbouring topics Australian companies established in 2000, Companies based in Sydney, Telecommunications companies of Australia, so understanding it makes those chapters shorter.
In everyday life: Look for Unwired 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.

Frequently asked questions

What is Unwired in simple terms?

Unwired Australia Pty Ltd was an Australian company dedicated to fixed wireless telecommunications network offering carrier grade Internet services. They provided coverage in Melbourne and Sydney.

Why does Unwired matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Unwired?
