Snapshots of the mobile industry show the huge and rapidly growing demand for data. According to the latest Ericsson mobility report, the global use of mobile data traffic has grown by 68 percent over the past year.

Growth in mobile data traffic is expected to increase in the coming years as 5G penetration increases and 4G coverage continues to expand. Ericsson expects 5G users to reach 2.6bn by the end of 2025, covering 65 percent of the world's population and generating 45 percent of total global mobile data traffic. It will be the fastest-growing mobile technology to date rolled out globally.

Three other ways 5G momentum will affect mobile users:

North America will lead the way. Thanks to the high adoption of communications technology by consumers in North America, the region is set to become one of 5G's hottest markets in the coming years. North America is expected to have 320 million 5G users or 74% of all mobile users. In addition, 91 percent of current wireless subscribers in the market are 4G, the highest share in the world. As service providers continue to deploy 5G networks across the continent, we will see more and more consumers switch to 5G.

Data consumption will increase dramatically.5G's fast adoption rate, speed, and low latency will drive data usage. The growth in mobile data traffic is driven by video, but there are other factors, including mobile gaming and the push for higher resolution.5G can also support more immersive media formats and applications such as VR/AR and 360 videos, providing the performance required for good user experience. The mobility report estimates that by 2025 in North America alone, the expected average mobile data usage per smartphone will be 45GB per month.

By contrast, service providers that launched nationwide 5G in South Korea in August averaged more than 25 gigabytes of mobile data per subscriber per month.
5G is the future, but 4G users will continue to grow modestly. Despite the new 5G networks, 4G will remain the network for people everywhere.

Currently, there are 4.34 billion users worldwide. That number is expected to grow modestly over the next six years, to $4.79 billion by 2025, in parallel with 4G. We can expect consumers from countries with the lowest subscription rates to account for a large proportion of this growth. In India, for example, 86% of the population has mobile subscriptions, mainly 4G and 2G. By 2025, the number of mobile subscribers in India is expected to grow by 3 percent and will consist mainly of 4G (80 percent) and 5G (11 percent).

In an era of faster and more complex smartphones, it's clear that people will only continue to increase the amount of internal capacity they consume on their mobile devices. To take advantage of the findings of this report, service providers need to provide their customers with networks that can withstand the rapid growth in data consumption over the next few years. For service providers and businesses, a greater focus on capacity and a deeper understanding of consumer behavior are critical.

The large-scale construction and upgrading of communication base stations have created a huge demand for high-frequency and high-speed PCB, and PCB is now facing a new round of upgrading demand.

Compared with the advanced level of foreign countries, China's electronic components industry still has a certain gap, facing many challenges. With international trade tensions and the advent of 5G, domestic manufacturers have an opportunity to catch up or be further extended.
