The Birth of 6G Technology
Since 2021, these industry giants have been focusing their research and development efforts on sub-terahertz technology. This technology operates in the higher frequency bands between 100 and 300 GHz, presenting both novel opportunities and formidable challenges. Unlike the existing 5G networks, which operate in the frequency bands below 100 GHz, 6G technology ventures into uncharted territories, necessitating the development of entirely new wireless devices and infrastructure.
Collaborative Innovation: Contributions from DOCOMO, NTT, NEC, and Fujitsu
Each member of this consortium has played a crucial role in advancing different aspects of 6G technology, pooling their expertise to overcome the inherent challenges of sub-terahertz frequencies.

Overcoming Challenges in the Sub-Terahertz Frequency Bands
Operating in the sub-terahertz frequency bands presents unique challenges that the consortium has had to address. One of the primary issues is signal attenuation, which increases with frequency, leading to shorter transmission ranges. To mitigate this, the consortium has developed advanced signal amplification and error correction techniques, ensuring that 6G signals can travel longer distances without significant degradation.
Another challenge is the need for line-of-sight communication at higher frequencies. Unlike lower frequency bands, which can penetrate obstacles like walls and buildings, sub-terahertz signals are more easily obstructed. The consortium has tackled this issue by incorporating sophisticated beamforming and beam-steering technologies, allowing 6G signals to navigate around obstacles and maintain robust connections.
Implications for the Future: Transformative Applications of 6G Technology
