Japan Unveils 6G Device, 500 Faster than 5G

In a groundbreaking move poised to redefine the landscape of telecommunications, a consortium of leading Japanese companies including DOCOMO, NTT, NEC, and Fujitsu has unveiled a cutting-edge 6G wireless device. This technological marvel boasts an unprecedented data transmission speed of 100 gigabits per second (Gbps), marking a monumental leap forward from the capabilities of current 5G networks.

With ambitions to position Japan at the forefront of 6G innovation, the consortium’s efforts signal a pivotal shift towards the next generation of information and communications infrastructure, slated for introduction in the 2030s. Unlike its predecessors, 6G is not merely an extension of conventional mobile communications but promises to revolutionize connectivity across diverse domains, including wired, wireless, land, sea, air, and space.

The key to this quantum leap lies in the utilization of higher-frequency bands, specifically the “sub-terahertz” spectrum ranging between 100 and 300 gigahertz (GHz). Unlike the millimeter-wave bands employed by 5G, which operate at frequencies below 40 GHz, 6G’s embrace of the sub-terahertz spectrum necessitates the development of entirely new wireless devices from the ground up.

Overcoming formidable obstacles required a concerted effort from each consortium member, with DOCOMO spearheading the design of wireless transmission equipment capable of achieving blistering data rates of 100 Gbps over a 100-meter range in the 100 GHz band. Meanwhile, NTT focused on pioneering high-end wireless equipment for the 300 GHz band, achieving comparable breakthroughs in data transmission capabilities.

NEC’s contribution centered on the development of sophisticated multi-element active phased array antennas (APAA) tailored for the 100 GHz band, while Fujitsu’s expertise in compound semiconductor technologies paved the way for efficient signal amplification in both the 100 GHz and 300 GHz bands.

The implications of these advancements are profound, transcending the realm of telecommunications to encompass a myriad of potential applications. From seamless ultra-HD video streaming to real-time control in autonomous vehicles, the possibilities afforded by 6G’s unprecedented data transfer speeds are virtually limitless.

As the world eagerly anticipates the dawn of the 6G era, Japan’s bold strides towards realizing this vision underscore the nation’s unwavering commitment to technological innovation and leadership on the global stage.
