SCIENCE: Scientists have sent data through the air at a speed of 938 gigabits per second (Gbps) – setting a new record for wireless transmission speed. New record close to 1 terabit per second (Tbps), 30 in 0.26 seconds Gigabyte (GB) is equivalent to downloading a 4K Ultra HD movie. In comparison, the U.S. It will take about 17 to 29 minutes to download using an average 5G connection in the U.S., which ranges from 140 to 230 megabits per second (Mbps). U.K. In the U.S., where the researchers are located, the average 5G speed is about 100 Mbps, which means the received data transmission speed is about 9,380 times faster.
Scientists achieved this for the first time by combining radio and optical techniques, enabling them to use radio frequency (RF) wavelengths up to 150 gigahertz (GHz). They outline their methods in a new study published October 15 in The Journal of Lightwave Technology.
Most 5G connections transmit data in “narrow” frequencies below 6 GHz. But these transmission bands are highly congested, meaning speeds fall far short of the theoretical maximum speed for 5G, which is 20 Gbps. But future 6G transmission speeds are likely to occupy higher frequencies than the narrow 5G band, which will let communications networks take advantage of much higher speeds. According to the Global Mobile Suppliers Association (GSA), these bands include “upper mid-band” frequencies from 7 to 24 GHz, as well as “sub-terahertz bands” from approximately 90 to 300 GHz.
U.K. “Current wireless communications systems are struggling to meet the growing demand for high-speed data access, users and fiber,” senior study author Zixin Liu, professor of electrical engineering at University College London (UCL), said in a statement. “Capacity in the last few meters between optic networks is holding us back.” “Our solution is to make more use of available frequencies to increase bandwidth, while maintaining high signal quality and providing flexibility in accessing different frequency resources. The result is super-fast and reliable wireless networks that seamlessly connect user terminals and the Internet. “Removes the middle speed barrier.”
