WorldTel

WorldTel 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 WorldTel rather than just read about it. In short: WorldTel Limited was established in January 1995 as part of an International Telecommunication Union initiative to help mobilize development of the telecommunications sector in developing countries. The primary catalyst for its creation was a McKinsey & Co. report recommending creation of a separate company for this purpose.

Key takeaways

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

Reference excerpt

WorldTel Limited was established in January 1995 as part of an International Telecommunication Union initiative to help mobilize development of the telecommunications sector in developing countries. The primary catalyst for its creation was a McKinsey & Co. report recommending creation of a separate company for this purpose. Sam Pitroda, who developed the telecommunications services in India, became its first chairman in May 1995. In 1996, $10 million of financing was announced, along with plans for 50 million telephone lines. WorldTel UK was awarded a 2001 license for services in Bangladesh. In 2004 Swedtel, based in Stockholm, was purchased by WorldTel UK Limited. In November 2007, Mohammad Nayeem Mehtab Chowdhury of WorldTel Bangladesh Holdings was arrested for allegedly forging the signature of Pitroda and withdrawing money from banks illegally that was intended for investment. In April 2008, WorldTel Bangladesh announced that Chowdhury was released and cleared of charges, and it would start service "soon" in Dhaka. In 2010, the Bangladesh Telecommunication Regulatory Commission raided the offices of WorldTel Bangladesh and seized voice over IP equipment. Around 2007 the UK company no longer filed financial statements, and was dissolved in 2011. The company maintained a web site through about 2010.

Worked examples

Example 1 — a first encounter with WorldTel

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

In research: WorldTel 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 WorldTel 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: WorldTel is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telecommunications companies of Bangladesh, Telecommunications company stubs, so understanding it makes those chapters shorter.
In everyday life: Look for WorldTel 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 WorldTel in simple terms?

Why does WorldTel 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 WorldTel?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
