Number of mobile devices worldwide 2020-2025

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.

2021年，全球运行的移动设备数量已达约150亿台，较上一年略微超过140亿台。预计到2025年，移动设备数量将达到182.2亿台，较2020年水平增长42亿台。随着设备数量的增长，我们对它们的依赖性也在不断加深，以满足日常功能和活动的需求。移动设备的应用场景对更快的数据连接速度和更低的延迟提出了更高的要求。5G网络对于满足这些需求至关重要，其运行速率显著高于4G。例如，在北美，预计到2025年将实现2.18亿个5G连接，较2020年的1000万个连接大幅增长。这意味着北美所有移动连接中约有48%。在全球范围内，这一比例预计将在2025年达到20.1%。展望6G：超越5G的时代。虽然5G已进入商业化阶段并创造了新的机遇，但研究人员和工程师们已经开始探索6G。随着移动设备数量的持续增长，以及未来几年蜂窝物联网（IoT）设备在更多工业领域的渗透，网络拥塞和数据传输速度的问题将最终需要解决。6G有望在问题出现之前解决这些问题，可能实现比5G网络连接密度高十倍的网络连接密度，以及峰值数据速率比5G快五十倍。美国联邦通信委员会已开放频谱进行实验，而中国已发射了一颗所谓的6G卫星，因此6G的实际潜力有望在未来十年内揭晓。
