Wavecom

Wavecom 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 Wavecom rather than just read about it. In short: Wavecom (acquired by Sierra Wireless in 2009) was a French technology company that developed and manufactured embedded wireless technology for Machine to Machine (M2M) communication, enabling transmission and reception of data and voice communications using wireless cellular network operators. Its technology was used in smart meter solutions, automotive telematics, fleet management systems, wireless alarms, wireless…

Key takeaways

Wavecom 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 Wavecom to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wavecom from memory before moving on to harder problems.

Reference excerpt

Wavecom (acquired by Sierra Wireless in 2009) was a French technology company that developed and manufactured embedded wireless technology for Machine to Machine (M2M) communication, enabling transmission and reception of data and voice communications using wireless cellular network operators. Its technology was used in smart meter solutions, automotive telematics, fleet management systems, wireless alarms, wireless POS devices, fixed cellular terminals and other M2M systems.

History Wavecom was founded in 1993 by Michel Alard, Aram Hékimian and André Jolivet. In its first three years of existence, Wavecom operated as an engineering consultancy primarily focused on wireless communication. By 1996, the founders realized there was a market for a standard GSM module, which could be integrated into mobile phones and other wireless applications. The first standard module was introduced in January 1997. Wavecom was acquired by Sierra Wireless in 2009.

Open AT OS

Open AT OS is an operating system provided by Sierra Wireless together with its wireless modules. It natively provides GSM related functions, such as GSM voice calls or data transfer related APIs, in addition to standard operating system functions. On Sierra Wireless modules, the application binary is downloaded beside the GSM function binary and both are executed at the same time on the processor.

Worked examples

Example 1 — a first encounter with Wavecom

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

In research: Wavecom 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 Wavecom 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: Wavecom is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2009 mergers and acquisitions, Companies formerly listed on the Nasdaq, Computer companies established in 1993, so understanding it makes those chapters shorter.
In everyday life: Look for Wavecom 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 Wavecom in simple terms?

Why does Wavecom matter?

Because it connects several computer 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 Wavecom?

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.
