The components needed for successful 6G communications
By Dr. Guillaume Ducournau, Professor and researcher in THz communications, Université de Lille, France
However, the deficiency of mmWave components could delay this leap forward in wireless communications.
A
Solving problems Whilst the rollout of 5G is still in its infancy, research is now heavily focused on solving a significant problem that will surface within the next few years. Antenna-to-antenna links – or the backhaul of the network – are essentially limited to frequencies under 100GHz. However, it is expected that, by 2025, the frequencies under 80GHz
cademia is hot on the heels of 6G, trying to resolve the challenges associated with introducing and running it successfully.
Currently there is a shortage of components, testbeds and even concepts to operate communications systems at
frequencies above 100GHz, and there are even fewer devices that work in the THz range

will no longer be enough to support the evolution of 5G and 5G Plus, especially in densely-populated areas. For 5G networks, at some point every user will expect to have access to at least 1GB/s, which means in crowded places like commercial centres or big cities there will be a need for managing enormous data rates at the antenna collecting point.
6G components needed While not yet a functioning technology, 6G will deliver data rates 100 times faster than 5G, and shift away from primarily connecting people and things to supporting connected robotic and autonomous systems (CRAS), unmanned aerial vehicles (UAVs), AI- based management systems and even
