5G and IoT Technology

5G technology and its impact on IoT

In the rapidly evolving landscape of technology, two acronyms have been making waves in recent years: 5G and IoT. The fifth generation of wireless technology (5G) and the Internet of Things (IoT) have garnered immense attention, promising transformative changes in the way we connect, communicate, and live. In this blog, we will embark on a journey to explore the intersection of 5G and IoT, their current status, challenges, applications, and their profound impact on shaping the future of our digital world.

According to Ericsson’s recent Mobility Report, there is a significant surge expected in the number of 5G smartphone subscriptions worldwide, reaching approximately 600 million by the end of this year. This figure is nearly triple the total seen in 2020. Additionally, the report predicts that by 2022, the number of 5G subscriptions will surpass the one-billion mark.

The Internet of Things (IoT) is poised to connect over 50 billion devices by 2030, promising a highly interconnected digital ecosystem. What makes this even more remarkable is that 5G networks will be approximately ten times faster than the current LTE networks. This substantial increase in speed will empower IoT devices to communicate and share data faster and more efficiently than ever before.

In the realm of business-to-business sales of IoT devices, it is projected that by 2030, a total of 44.8 million 5G Internet of Things (IoT) units will be sold. Of these units, nearly half are expected to be utilized in Industry 4.0 applications, often referred to as smart factories. The second-largest segment of projected sales in 5G IoT units is expected to be in use cases related to smart cities, with a figure of 8.4 million units.

Among the various IoT segments, connected cars are set to become the largest in the global 5G Internet of Things (IoT) endpoint market. By 2023, it is anticipated that connected cars will hold an installed base market share of 39 percent, equivalent to approximately 19 million endpoints. The overall installed base of 5G IoT endpoints is projected to grow significantly, expanding from 3.5 million in 2020 to an estimated 49 million worldwide by 2023.

This remarkable growth in the adoption of 5G technology is expected to have a significant economic impact. The industry that stands to benefit the most economically is information and communications, with an estimated contribution of around $251 billion to the U.S. GDP between 2021 and 2025. Additionally, the real estate and business services industries are forecasted to contribute $190 billion and $187 billion, respectively, to the economy in the next five years.

Now that we have a comprehensive understanding of the potential of IoT in 5G technologies, let’s delve into a detailed exploration of the advantages that IoT and 5G bring to the table.

The Impact of 5G on the Internet of Things

5G technology is not merely an incremental improvement over its predecessors; it represents an important shift in wireless communication. With significantly higher data speeds, ultra-low latency, and massive device connectivity, 5G opens up a world of possibilities for IoT applications.
