Fujitsu Network Technologies

Secure networks that operate with speed and energy efficiency from the edge to the core

Meeting sustainable business transformation agendas with 5G network solutions

Bandwidth demand shows no sign of decelerating. And as we move towards a borderless convergence, where physical reality is modelled in metaverse-like digital twins, there is an even greater call for ultra-fast networks.

Businesses are now exploring high-bandwidth private 5G networks to underpin sustainable transformation agendas in environments such as customer premises, factories, warehouses, and hospitals. Whether it is a smart factory or a smart city, digital twins are starting to be used to process IoT sensor edge data across multiple industries, especially in automotive, transportation, manufacturing, energy, utilities, and healthcare.

Fujitsu is focused on providing sustainable 5G network solutions that are more energy efficient, ensure better performance, and deliver higher network quality.

Leveraging AI and the quantum-inspired Digital Annealer to optimize computing resources, Fujitsu has successfully developed a new 5G vRAN technology to deliver high performance and reduce energy consumption. This reduces overall system CO2 emissions by 50% or more compared to conventional vRAN technology.

With higher frequencies and shorter signal propagation than 4G/LTE, 5G typically involves a larger number of smaller-cell deployments. This pattern could drive up infrastructure and maintenance costs if proprietary protocols and technologies resulted in vendor lock-in. To mitigate this risk, Fujitsu has already introduced new cloud-native 5G base stations based on the Open RAN (O-RAN) open standard.

Fujitsu is investing in the future of 5G networks, 6G, and optical communications

The high bandwidth of 5G networks – which will only intensify when 6G arrives in about 2030 - means so much more data will cross national and private networks that current core network backbone technologies will no longer be adequate.

Fujitsu’s research is looking beyond 5G and 6G to photonics-electronics convergence, where signals encoded in light waves transmit information. Photonics-electronics convergence in computing will also reduce energy consumption significantly.
