Scientists have sent data through the air at speeds of up to 938 gigabits per second — setting a new record for wireless transmission speeds.
Most 5G connections transmit data in"narrow" frequencies below 6 GHz. But these transmission bands are highly congested, meaning speeds tend to be much lower than the theoretical maximum speed for 5G, which is 20 Gbps. "Our solution is to use more of the available frequencies to increase bandwidth, while maintaining high signal quality and providing flexibility in accessing different frequency resources. This results in super-fast and reliable wireless networks, overcoming the speed bottleneck between user terminals and the Internet."
The new approach combines two existing wireless technologies for the first time — high-speed electronics and millimeter wave photonics, Liu added. The latter technology uses photonics, or light, to generate millimeter-wave radiofrequency signals. This hybrid system enables large amounts of data to be transmitted wirelessly over bands that could be used in future systems like 6G.
