While 5G is still a few years out from being mainstream, 6G research is already underway and is expected to be commercialised by 2030. Its ultra-low latency and increased bandwidth will deliver massive amounts of data across decentralised, intelligent networks.
The emerging vision for 6G is to make possible near instant and ubiquitous connectivity to transform how the human, physical, and digital worlds interact. It will both expand upon and go far beyond the capabilities of 5G, marking a new era of wireless that accelerates digitalisation and drives business innovation across critical industries.
6G’s environmental sustainability use cases
Besides an economic boon, it has become imperative that the technologies of tomorrow deliver positive environmental and social change, and 6G is foundational to this vision. As climate change brings rising temperatures and extreme weather, global citizens are demanding urgent action.
135 countries and hundreds of companies worldwide have pledged carbon neutrality. The technology sector is poised to create long-term solutions toward environmental sustainability. In particular, electronic design can support the development of clean energy systems, data analytics for environmental applications, and machine technology advancements that reduce carbon emissions.
By focusing on sustainability as a key driver of 6G research, we will discover new ways to combat climate change in the following industries and beyond.
Transportation
6G will enable innovations in smart transportation and logistics, including connected vehicles and transit infrastructure. The growth in driverless electric vehicles will not only promote clean energy but will also reduce emissions by optimising traffic flow. These outcomes will be made possible by applying wireless connectivity to sensor technology, distributed computing, and AI. This combination of new technologies will allow vehicles, traffic cameras, and roads to communicate and coordinate in real time.
The Global System for Mobile Communications Association (GSMA)’s 2020 Mobile Industry SDG Impact Report found that the increase in vehicle monitoring, route optimisation, and fuel efficiency through telematics helped avoid approximately 105 million tons of greenhouse gases in 2018 — equivalent to taking 23 million cars off the road.
Manufacturing
6G will build upon 5G’s ability to modernise all stages of manufacturing — from product design to the factory floor to the warehouse. Connected machines and cooperative robotics will be able to orchestrate all manufacturing and supply chain management activities, automating once-manual processes to enable more efficient and resilient supply chains.
6G-enabled manufacturing plants will also advance our ability to monitor and manage energy and water usage, reduce carbon emissions, and leverage renewable energy to power operations. For example, Ericsson’s Smart 5G Factory reduced waste reduction by 5%, saved 5% on energy costs, and increased overall energy efficiency by 24%.
Agriculture
One of the main benefits of 5G and eventually 6G is expanding wireless access to rural areas. This opens new sustainability opportunities for the agricultural sector, where chemical fertilisers, pesticides, and animal waste release harmful greenhouse gases into the atmosphere.
Smart agriculture unlocks new ways to optimise crop production, conserve resources, improve soil health, and monitor livestock — all helping farmers reduce their carbon footprint.
Energy
As the world’s population grows, so does the need to manage and reduce fossil fuel consumption. 6G will help the critical transition to renewable energy, as well as further advance the development of smart grids.
Smart grids will enable communities to better monitor increasing energy demands, optimise electrical distribution, and use automation to manage large variations in loads. A Qualcomm report found 5G-connected smart grids will reduce gas and electricity consumption by 12% — and 6G will accelerate that progress.
ICT (Information and Communications Technology)
It is to be recognised that the telecommunications and technology sectors have an outsized influence on the economy, thus have similarly outsized influence on energy consumption.
The ICT industry already has a large footprint (about 1/10th of global electricity consumption), and is projected to rise significantly. The wireless communication industry, which is a big part of the ICT sector, has made it a primary 6G objective to reduce its energy usage and incorporate sustainability in its operational processes and lifecycle management.
Currently the Radio Access Network (RAN) consumes a major share of the energy (>50%) of the wireless network architecture. A variety of techniques, such as smart idling of radios and resource pooling, have already been incorporated into 5G, and more advanced approaches are under consideration for 6G.
Just like 5G, the next generation of connectivity represents a massive opportunity to impact technology, business, and society at large. Keysight looks forward to defining standards and creating the technological building blocks to deliver a human-centric, sustainability-focused 6G network that changes lives, secures the world, and connects people across the globe.
