A major technological revolution is about to take place in the internet world, which could completely transform the way people download and stream online. Japanese scientists have developed a 6G prototype device that has created a stir in the wireless internet industry. According to media reports, it is considered the world’s first 6G device. With this new technology, researchers achieved a whopping wireless internet speed of 112Gbps, which is said to be more than 20 times faster than existing 5G networks.
Until now, scientists developing 6G networks have been using extremely high frequencies, but beyond a certain point, normal electronic circuits stop functioning properly. Especially when signal frequencies exceed 350 GHz, digital noise increases significantly. This causes data to become unstable and internet connections to become unreliable.
Takeshi Yasui’s team at Tokushima University has found a solution to this significant challenge. By overcoming traditional electronic limitations, the researchers achieved record wireless speeds of 112Gbps in the 560 GHz band without any signal interruption. This achievement is considered crucial for the future of 6G technology.
Light technology used to replace old electronics
Photonics, or light-based technology, played a major role in this success. Scientists used light-based technology instead of conventional electronic circuits. A unique device called an optical microcomb proved crucial in this experiment.
The optical microcomb can be thought of as a highly advanced laser system that produces a highly stable and precise light beam. Because these light signals are highly stable, they produce virtually no digital noise. This is why scientists were able to generate extremely fast terahertz signals that can transfer data without interruption.
Generally, in laser-based technologies, even slight vibrations can disrupt the system, disrupting laser alignment. To address this issue, Japanese scientists permanently connected optical fibers directly to a silicon nitride microresonator chip. This reduced the device’s size and eliminated alignment issues.
The research team also incorporated a unique temperature control system to ensure that changing weather and temperatures do not impact the device’s performance. It is believed that this technology could transform the future of ultra-fast internet and next-generation wireless networks.
