An important building block of 6G technology is the Sub-THz frequency range.
Sub-THz (100 into the 300 GHz) promises to be indispensable to achieve target requirements in terms of maximum throughput on the 1 Tbps level and extremely low latencies.
But Sub-THz waves will also likely be the foundation for intriguing novel applications. The access to much wider bandwidths will enable very high-throughput short-range communication combined with a sense of the environment for object detection or the next generation of gesture recognition down to millimeter resolution.
The vision is that in the 6G era, the digital, physical and human world will seamlessly fuse (cyber-physical fusion), leading to a connected society in which communications connects people, machines and virtual services with all of the necessary components of our daily life. The deployed sensors and actuators need to securely transfer and process data at extremely high rates to realize “immersive communications” of this kind.
For 6G, the targeted values are more stringent by a factor of approx. 10 times to 100 times compared to 5G and will pose new challenges for wireless communications and transport networks.
Efficient operation of wireless systems is highly dependent on adequate waveform design. While OFDM remains a strong candidate for 6G waveforms, alternative application-specific waveforms or unified scalable waveforms need to be explored, for example, for joint communications and radar sensing.
Moreover, the different spectrum ranges, device characteristics (phase noise, PA power efficiency) and system characteristics (signal bandwidth) must be taken into account. A number of new waveforms are under consideration, including orthogonal time frequency space modulation (OTFS) for high mobility scenarios with large Doppler spreads.
Furthermore, single carrier waveforms may play a more dominant role to fulfill the requirements for power efficiency in future devices. To allow more flexible use of wireless channels, it could be beneficial to relax the orthogonality constraint, as is realized for non-orthogonal multiple access (NOMA).
Want to learn more? Tonex offers 6G THz and Sub-THz Training, a 2-day course that covers key 6G technologies with an emphasis on the THz frequency band, which is in the range of 100 GHz to 300 GHz, and THz, which is from 300 GHz to 3 THz on the spectrum chart.
Participants will examine the benefits and challenges of coupling 6G with the THz frequency band.
Additionally, attendees will examine how THz signals have the capacity to drive advanced 6G technological applications such as digital twins, immersive extended reality (XR), mobile holograms and digital replicas, nano healthcare, three-dimensional (3D) calls, haptics communications, unmanned mobility, tele-operated driving and the nano-inspired internet of things.
