And they got away with it. Disclaimer: This article uses the term "GSM Mafia" as a historical industry nickname. No criminal activity, violence, or actual organized crime was involved in the development of the GSM standard.
The story goes like this: In 1987, the group was deadlocked over whether to use Frequency Division Multiple Access (FDMA) or the new, unproven Time Division Multiple Access (TDMA). The meeting had failed. The next morning, over coffee and croissants, Haug and Dupuis wrote a compromise on a napkin. By lunch, they had arm-twisted Germany into agreeing. By dinner, the vendors were told—not asked—to build chips for a hybrid system.
The truth is messier. The GSM Mafia were not heroes or villains. They were engineers who understood that technology is politics by other means. They didn't ask for permission. They asked for consensus—and when that failed, they asked for forgiveness.
