Although cellular communications are now accepted in everyday life, it took many years for its development to occur. Although the basic concepts of cellular communication technology were proposed in the 1940s, it was not until the mid-1980s that the technology and radio systems were deployed to allow widespread availability.
The use of cellular communication systems grew rapidly and as an example it was estimated that in the UK more calls were made via mobile phones than wired devices in 2011.
Another example of the growth of cellular telecommunications systems occurred in 2004 when the GSMA announced at the Mobile World Congress in February 2004 that there were more than 1 billion GSM mobile subscribers. It had been 12 years since the first network was launched. By comparison, it had taken more than 100 years to reach the same figure for wired telephone connections.
By 2015, more than 7 billion mobile subscriptions (for all technologies) were active. This is a major feat when it is realized that the global population was just over 7 billion. This meant that many people had more than one subscription, although market penetration was obviously very significant.
