The future of electronics is evolving rapidly as wireless communication advances. If you own a mobile phone, you are likely familiar with seeing 3G, 4G or even 5G symbols at the top of your screen.

These figures represent different generations of wireless communications technology that support our cellular data networks.

It all started in the 1980s with 1G, the first generation of wireless technology. Since then, we have rapidly progressed through the generations. For instance, the first commercial 3G networks appeared in the UK in mid-2001. Moreover, international standards such as ISO 9001 quality guidelines help ensure these networks meet rigorous technical requirements.

Now, some mobile customers have access to 5G networks. This is the fastest technology to date. It provides reliable connections to services like mobile broadband and the internet of things (IoT). However, this is only the beginning…

Although 5G is still in its infancy, we are already discussing what comes next: 6G. This new generation of communications technology is likely to change how businesses use digital devices. Consequently, it will influence how electronics manufacturers design the future of electronics…

In today’s tech-first society, people expect high speed from wireless mobile devices.

These capabilities rely directly on wireless communications technologies. Furthermore, these networks get smarter and more reliable with every new generation. But how do they work?

Simply put, connections are facilitated by a network of antennas. These antennas transmit radio frequencies to connect devices to online services.

The second generation was the first to employ digital networks. Consequently, it allowed mobile users to transmit data for text messaging. Then, 3G increased bandwidths and improved data transfer rates. This enabled people to send larger messages easily.

After that, 4G and 4G LTE arrived to enable interactive multimedia at high speeds. In 2019, mobile operators launched 5G to bring several superior features. For example, it offered extremely low latency.

With these wireless technologies, people and businesses gain unprecedented opportunities. These range from enabling machine-to-machine communications to generating data for decision-making.

Despite these benefits, the uptake of 5G has been relatively slow. In fact, Ericsson estimated that global 5G population coverage reached only 30% by late 2022 due to infrastructure gaps. Nevertheless, executives predict that 6G will arrive in 2030.

So, what could 6G offer when it arrives?

Telecommunications experts are currently defining future standards.

However, we know that 6G will offer higher frequencies, greater capacity, and lower latency. The next generation will likely enable rapid data transfer. In fact, it could be 100 times faster than 5G. Thus, it will facilitate instantaneous communications between devices.

The rollout of 6G will take the IoT to new heights. In addition, it delivers the bandwidth needed to supercharge the metaverse. From virtual meeting spaces to 3D social media, possibilities are endless.

We can also expect an influx of 6G-enabled smart devices. With seamless connectivity, consumers and businesses harness data on an unprecedented scale.

For example, healthcare stands to benefit greatly from this wireless iteration. Electrical components continue to shrink, helping designers create smaller sensors. Consequently, superfast 6G data speeds could revolutionise healthcare.

Working alongside the IoT, 6G networks could support AI, AR, and VR capabilities. This technology could also bring us ‘smart hospitals’. As a result, it improves cybersecurity while allowing providers to monitor patients remotely.

The possible uses for 6G devices remain largely theoretical today. However, developers cannot afford to stand still in this fast-paced world.

Therefore, manufacturers must look ahead to the future of electronics to prepare for 6G…

Before we enjoy 6G advantages, the industry must develop suitable infrastructure.

For instance, this emergence will significantly impact printed circuit board (PCB) design. Because 6G operates at frequencies of 100 GHz and above, PCB manufacturers need advanced tools. Thus, they can create complex structures suitable for high rates.

Engineers must also seek new materials with multilayer capacities. These materials withstand high radio frequencies without overheating. Additionally, PCB designs for 6G-enabled IoT electronics must include millimetre-wave (mmWave) circuits.

In short, mmWave is a frequency band operating at 30–300 GHz. It carries vast amounts of data using distributed mesh networks. Consequently, it will be crucial for 6G development.

The next generation of wireless technology is on its way. Therefore, manufacturers must start working now to realize future 6G devices.
