On the cusp of 6G, are we also on the verge of a materials breakthrough?

The world has barely experienced a fraction of the services 5G mobile promised to deliver, and already the drive toward 6G is gathering momentum. The standardization process begins this year, and the final specifications are expected to be released in 2028, with rollout beginning in 2030. It’s proof, if more were needed, that we are an impatient and ambitious species.

Ericsson has helpfully described the 6G standardization process, which is expected to permit a much cleaner transition than we have seen in the move from 4G to 5G. Although 6G will leverage some 5G infrastructure, particularly in the core, connectivity will be standalone from the start and should perform better as a result. It’s hard to grasp, but 6G data rates and latency are expected to be about 1000 times faster than those of 5G.

The bigger picture is working toward a pervasively connected world that supports our lives and adapts to our needs, wherever we are and however those needs change in real-time. Wireless is the only connectivity that can do this for us. Realizing the necessary connections is extremely challenging at every level, from the standards-setting efforts undertaken by the 3GPP, the global body managing mobile standards, to the subcomponent level – including the new materials we must develop to build the systems that can realize the performance promised in the specifications.

The humble printed circuit board continues to change to meet new demands.

Power is nothing without control. It’s not a quote by a famous politician or social commentator, or even Mark Twain. It’s an advertising slogan for car tires. But it’s also an apt description of the opportunities for our industry that are now happening as part of the green energy transition.

Electrification is one of today’s dominant megatrends. The “old way” of releasing energy from traditional fuels by explosions and burning is giving way to alternatives like electromagnetic and photovoltaic conversion, as well as chemical processes inside batteries and fuel cells. Taking the utmost care of every joule is critical to maximize the harvest from the scarce ambient energy sources and to minimize waste throughout the conversion system, distribution infrastructure, storage and – ultimately – the load.

Exercising that care demands control. This is where more power electronics are being employed to ensure efficient and precise conversion as we accelerate the pace of electrification; changing traditional mechanical, hydraulic, and fossil-fueled tools and vehicles that we have all become accustomed to using into electrical equivalents that can be powered from clean and sustainable energy. Replacing conventional boilers with electric heat pumps for heating buildings is one example.
