Siemens Mobile

Siemens Mobile 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 Siemens Mobile rather than just read about it. In short: Siemens Mobile was a German mobile phone manufacturer and a division of Siemens AG. Siemens sold Siemens Mobile to the Taiwan-based BenQ in 2005, subsequently becoming BenQ-Siemens and succeeded by Gigaset.

Key takeaways

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

Reference excerpt

Siemens Mobile was a German mobile phone manufacturer and a division of Siemens AG. Siemens sold Siemens Mobile to the Taiwan-based BenQ in 2005, subsequently becoming BenQ-Siemens and succeeded by Gigaset. The last Siemens-branded mobile phones, the AL21, A31 and AF51, were released in November 2005.

History The first Siemens mobile phone, the Siemens Mobiltelefon C1, was launched in 1985. In 1994 the Siemens S1 GSM phone was launched. In 1997 Siemens launched the first phone with a colour screen, the Siemens S10, with a screen capable of displaying red, green, blue and white. In the same year Siemens launched the first "outdoor" phone, the Siemens S10 Active, with enhanced shock, dust and splash protection. Siemens launched the first slider phone, the Siemens SL10, in 1999. Siemens acquired the mobile phone division of Bosch in 2000. In the same year Siemens launched one of the first phones with an MP3 player and external memory card support (MultiMediaCard), the Siemens SL45. In 2003 Siemens launched its first phone running on the Symbian OS operating system, the Siemens SX1. The phone featured hot swappable MultiMediaCard. In the same year Siemens launched the Xelibri range of fashion phones. In 2005 Siemens launched the first phone with real GPS support, the Siemens SXG75. As of Q3 2000, Siemens had an 8.6% mobile handset market share, putting it behind Ericsson, Motorola and Nokia. For the calendar year 2003, Siemens was again fourth behind Samsung, Motorola and Nokia, with a figure of 8.5%. In 2004 it decreased to 7.2%. Siemens Mobile was making large losses and plummeting sales at this time. By the first quarter of 2005, market share was down to 5.6% as it fell behind competitors LG and Sony Ericsson. Their Xelibri range of phones, which was the company's answer to the fashionable handset trend at the time, became a costly failure. On 7 June 2005, the Taiwanese company BenQ agreed to acquire the loss-making Siemens Mobile from Siemens, together with exclusive right to use the Siemens trademark on its mobile phones for 5 years. Before transferring the mobile phone subsidiary to BenQ, Siemens invested 250 million euros and wrote down assets amounting to 100 million euros. Siemens also acquired a 2.5% stake in BenQ for 50 million euros. BenQ subsequently released mobile phones under the BenQ-Siemens brand, from its German unit. In 2006 the German unit of BenQ filed for bankruptcy. Siemens restarted the production of mobile phones under the Gigaset brand name.

Products

Classifications Depending on their name, the Siemens mobiles have the following classifications:

A series: low-cost phones with basic functionality. C series: mid-range phones. M series: phones with military specifications for outdoor activities. S series: flagship phones U series: UMTS devices manufactured in 2003 by Motorola Mobility, USA and rebranded under "Siemens" name. Secondary alphabet position initials xF cradle phones xL sliding phones (exceptions: Siemens SL45 and Siemens CL75) xX phones with advanced features xK phones with a full QWERTY keyboard (Siemens SK65) Within a class, the numbers have the following meaning:

the first digit (1-9) denotes the level of functionality of the phone; the second digit indicates the generation of the phone. The phones are also of the first generation of the model, containing the numbers 1, 6, 8.

Worked examples

Example 1 — a first encounter with Siemens Mobile

Start with the simplest possible case. Write down what Siemens Mobile 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 Siemens Mobile 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 Siemens Mobile 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 Siemens Mobile

In research
Siemens Mobile 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 Siemens Mobile 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
Siemens Mobile is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1985 establishments in West Germany, Consumer electronics brands, Defunct mobile phone manufacturers, so understanding it makes those chapters shorter.
In everyday life
Look for Siemens Mobile 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.
