In 2021, the number of mobile devices operating worldwide stood at almost 15 billion, up from just over 14 billion in the previous year. The number of mobile devices is expected to reach 18.22 billion by 2025, an increase of 4.2 billion devices compared to 2020 levels.
Moving forward with 5G
As the number of devices grows, so does our dependence on them to fulfill daily functions and activities. The use cases for mobile devices increasingly demand faster connection speeds and lower latency. The 5G network will be critical to fulfilling those demands, operating at significantly faster rates than 4G. In North America, for example, it is expected that there will be
218 million 5G connections, up from just ten million in 2020. This means around 48 percent of all mobile connections in North America.
Globally, this figure should reach 20.1 percent by 2025.
6G: looking beyond 5G
While 5G has entered commercialization and is already creating new opportunities, researchers and engineers are already experimenting with
6G. Not only will the number of mobile devices continue to grow but cellular
internet-of-things (IoT) devices are set to permeate more industrial sectors in the coming years, meaning a solution will eventually be required for network congestion and data transfer speeds.
6G ought to be capable of solving those problems before they arise, potentially enabling a
network connection density ten times greater than that of 5G, and
peak data rates up to fifty times faster than the rate of 5G. The Federal Communications Commission in the United States has opened spectrum for experimentation, and China have already launched what is described as a 6G satellite, so that actual potential of 6G should be revealed over the coming decade.
