Japan develops 6G devices 20 times faster than 5G networks

The high-speed 6G wireless device, developed by a group of Japanese telecommunications companies including DOCOMO, NTT Corporation, NEC Corporation, and Fujitsu, can transmit data at 100 Gbps over a distance of 100 m.

These companies have collaborated on research and development of near-terahertz equipment, paving the way for the 6G era from 2021. They recently tested ultra-fast transmission of 100 gigabits per second (Gbps) at 100 GHz and 300 GHz over a distance of 100 m.

The frequency range of the electromagnetic spectrum used by the network is the fundamental difference between 5G and 6G. Faster data transfer speeds often come with higher frequencies.

5G signals are transmitted in the sub-6 GHz band and extend into bands around 40 GHz, called "millimeter wave bands". But with the 6G network, a higher frequency band in the range of 100 - 300 GHz will be needed, called the "near terahertz band" and will require completely different wireless equipment.

According to the companies, they need to find the exact performance standards that wireless devices operating in the sub-terahertz range need to meet.

To create high-speed 6G devices, each member company undertakes an important task in upgrading sub-terahertz technology.

DOCOMO conducts a wireless system configuration analysis for a 100 GHz telecommunications application and tunes the wireless transmission equipment to be able to transmit data at speeds of up to 100 Gbps over 100 m.

NEC researched a solution for 100 GHz wireless systems to create a complex active phased array antenna (APAA) with more than 100 parts.

NTT undertakes the development of high-end wireless equipment, focusing on 300 GHz equipment, helping to develop 300 GHz frequency wireless equipment that can transmit at 100 Gbps over 100 m.

Fujitsu develops new semiconductor technology that enhances signals at 100 GHz and 300 GHz frequencies with high performance.

Experts emphasize that when 6G technology provides seamless connectivity in the future, there will be limitless potential, allowing many applications from sending ultra-high definition video to real-time automatic vehicle control. , while increasing communication needs.
