The presentation tried to answer some key questions about mobile communications: Why is it the technology that reached a billion people worldwide faster than other technology mankind invented so far? Even though it is the ultimate challenge for engineers? What are these challenges and how can they be overcome? Why did GSM make it, but not Iridium or American CDMA? What about critical issues like health, privacy, ...? Is there humanity without communication?
