Reference excerpt

Vodafone Mobile Connect USB Modem branded as Vodem is a product of Vodafone that connects to the broadband internet. It is connected to the computer via USB which makes the product usable to virtually any computer, desktop or laptop. Huawei E220, K3806 and K3772H Vodem sticks are manufactured by Huawei for Vodafone. The K3772Z Vodem stick (note the 'Z' suffix) is manufactured by ZTE for Vodafone.

Drivers and installation Using this USB modem, customers are able to access 3G broadband services, from many types of computer. The software self installs from the modem, reducing the need for technical expertise from users. Vodafone's Mobile Connect Lite software self-installs through a Windows's auto-start feature. It uses the executable : VodafoneUSBPP.exe This device is also supported in Linux, using Vodafone Mobile Connect Card driver for Linux, which can be downloaded from the Vodafone Global website If this modem is to be used on Windows Vista, it must first be updated to the latest firmware on a Windows XP system, as the modem does not function on Windows Vista with the default firmware.

Speed Using HSDPA technology, it offers download speeds of up to 3.6 Mbit/s and upload speeds of up to 384 kbit/s, which depends on Vodafone's network on each of the countries offering 3G services. Unfortunately, speed degrades rapidly when getting to the fringe of coverage or inside buildings where signal strengths fades. This commonly results in almost unusable speeds of 6.6Kbs for receiving and 68.8 Kbs for sending, which is a symptom even in Central London locations. There are however commercial solutions available to increase signal strength by attaching external antennas to the Huawei E220. When outside of 3G broadband coverage, customers will automatically be able to access the web using Vodafone's existing GPRS services. Most Vodems and Vodem sticks are of reaching 7.2 Mbit/s. The original Huawei E220 supports up to 3.6 Mbit/s, and can connect up to 7.2 Mbit/s with a firmware upgrade. The Vodafone K5150 Vodem is a CAT4 4G device, capable of download speeds of up to 150 Mbit/s on a 4G LTE network and 42.2 Mbit/s with a dual-carrier network. The Vodafone Pocket WiFi is capable of download speeds of up to 150 Mbit/s on a 4G LTE network and 50 Mbit/s with a dual-carrier network.

Worked examples

Example 1 — a first encounter with Vodafone Mobile Connect USB Modem

Start with the simplest possible case. Write down what Vodafone Mobile Connect USB Modem 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 Vodafone Mobile Connect USB Modem 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 Vodafone Mobile Connect USB Modem 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 Vodafone Mobile Connect USB Modem

In research: Vodafone Mobile Connect USB Modem 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 Vodafone Mobile Connect USB Modem 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: Vodafone Mobile Connect USB Modem is common in secondary-school and first-year university syllabi. It links to neighbouring topics Modems, Vodafone, so understanding it makes those chapters shorter.
In everyday life: Look for Vodafone Mobile Connect USB Modem 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.
