An important selling point of Siemens’ mobile phone network technology is its high level of reliability even in extreme conditions. A film showing the demanding tests the technology is subjected to was developed for the company to display at trade fairs.

The film is impressive because of its combination of live shots of the tests with high-quality archive material that symbolises extreme conditions such as heat, cold, humidity and earthquakes. Animated text conveys additional facts so that the film can also be shown without sound.
