Five generations of cellular standards have fundamentally changed our lives, but the world of mobile communications is still evolving
Strictly speaking, the history of wireless begins with Heinrich Hertz. In the year 1886, he was the first person to generate and verify the existence of radio waves. In 1912, the first radio telegraph system developed by Guglielmo Marconi was used aboard the sinking Titanic to send an emergency SOS. Once the underlying physical foundations were mastered, standardization of mobile communications could begin.
Beginnings: 1G and 2G
The first cellular generation (1G) is remembered for its analog voice transmission and bulky mobile phones that have very little in common with modern devices.
In 1982, Groupe Spécial Mobile (GSM) was founded – the starting shot for cellular technology across Europe. The idea was that frequencies for mobile communications should be allocated only to operators who agreed to use the GSM standard. This made proprietary systems a thing of the past. Travelers no longer needed to buy a separate mobile device for every European country.
2G introduced digital voice transmission and the short message service (SMS). Furthermore, a new type of ecosystem emerged consisting of network operators, infrastructure providers, device manufacturers and T&M specialists.
