The internet world is witnessing a major technological shift that could completely change the way people download and stream online content. Japanese scientists have created a 6G prototype device, which has created a stir in the wireless internet industry. According to media reports, it is considered to be the world’s first 6G device. Using this new technology, researchers have achieved astonishing wireless internet speeds of 112 Gbps – said to be 20 times faster than existing 5G networks.
Solution to the biggest challenge of 6G
Until now, scientists building 6G networks were using much higher frequencies; But, beyond a certain limit, common electronic circuits stop functioning properly. In particular, when the signal frequency exceeds 350 GHz, the level of digital noise increases significantly. As a result, data transmission becomes unstable, and the Internet connection loses its reliability.
Japanese scientists set a new record
A team led by Tokushima University scientist Takeshi Yasui has successfully found a solution to this major challenge. Overcoming traditional electronic limitations, researchers achieved record-breaking wireless speeds of 112 Gbps within the 560 GHz band, completely free from any signal interference. This achievement is being considered an important milestone for the future of 6G technology.
Technology based on light replaced traditional electronics
The biggest contribution to this success was photonics – that is, technology based on light. Instead of relying on common electronic circuits, scientists used techniques based on light. A special device named “Optical Microcomb” proved to be extremely important for the success of this experiment.
Optical microcomb reduces digital noise
The optical microcomb can be considered a very advanced laser system, which is capable of producing extremely stable and precise light beams. Because these light signals have such high stability, there is almost no chance of digital noise being introduced into them. This is why scientists have been successful in creating extremely fast terahertz signals, which are capable of transferring data without any interference.
Making the device more stable and practical
Typically, in laser-based technology, even the slightest vibration can break down the entire system as it can cause the laser to be out of alignment. To overcome this problem, Japanese scientists permanently attached optical fibers directly to a silicon nitride microresonator chip. This reduced the size of the device and also eliminated the problem of alignment.
Additionally, the research team also incorporated a special temperature control system to ensure that fluctuations in weather and temperature do not have any adverse effect on the performance of the device. It is believed that this technology can revolutionize ultra-fast internet and next generation wireless networks in the future.
