Imagine Communications

Imagine Communications is a computer 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 Imagine Communications rather than just read about it. In short: Imagine Communications is an Irish internet service provider and telecommunications operator, who provide WiMAX, wireless broadband and resell Eircom telecommunications wholesale packages. The company operates in Ireland, the United Kingdom, the Netherlands, Austria, Norway and the United States.

Key takeaways

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

Reference excerpt

Imagine Communications is an Irish internet service provider and telecommunications operator, who provide WiMAX, wireless broadband and resell Eircom telecommunications wholesale packages. The company operates in Ireland, the United Kingdom, the Netherlands, Austria, Norway and the United States.

Services The company was set up as GTS Ireland on 15 November 1993. Imagine briefly operated the first Irish mobile virtual network, "Cellular 3", which bought airtime from Eircell. A legal challenge ended the arrangement and Imagine exited the mobile market. The "Cellular 3" name was derived from Imagine's de facto position as Ireland's third mobile operator at the time; Meteor Mobile Communications, the third physical operator, had yet to be licensed. Imagine later became the first company to introduce mobile WiMAX technology to Ireland. As of 2010, the company provides services to 17,000 businesses. Imagine has affiliations with several brands, including Motorola, HP, and Intel.

Related companies Clearwire was acquired by Imagine in 2010 Irish Broadband was acquired by Imagine in 2008 Cinergi Telecom was acquired by Imagine in 2007 Subsidiary Gaelic Telecom, which donates a percentage of each bill to a customer's selected GAA club or National school Access Telecom Bandwagon (music portal), partially owned as of 2006 Open Solutions provides network administration and related services

Worked examples

Example 1 — a first encounter with Imagine Communications

Start with the simplest possible case. Write down what Imagine Communications claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Imagine Communications 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 Imagine Communications 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 Imagine Communications

In research: Imagine Communications appears in computer 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 Imagine Communications 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: Imagine Communications is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies established in 1993, Mobile virtual network operators, Telecommunications companies of the Republic of Ireland, so understanding it makes those chapters shorter.
In everyday life: Look for Imagine Communications 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.
