Researchers at the University of California have developed a chip that operates at frequencies above 100 GHz, the bandwidth of which is four times higher than the capabilities of the current standard 5G. the new architecture in the future can replace kilometers of optical cables in data centers with a significant reduction in equipment costs.
Researchers managed to "jump" the bandwidth limit of 5G devices with the help of the original architecture of the chip "through-transmitter-receiver", which significantly reduces the requirements for digital processing, modulating digital bits in the analog and radio frequency areas. The unique configuration of the transceiver also allows it to consume significantly less energy than modern systems, reducing the cost of ownership of the device.
"We called our chip 'super-5G'. Its total speed of data transmission and reception is several times higher than the capabilities of the fifth-generation networks. In addition, the work at higher frequencies potentially allows you to provide most of the bandwidth directly to Telecom operators," says the author of the project Payam Heidari.
Operating frequencies over 100 GHz have recently been licensed by the US government. The development of the University of California — the first of its kind device that can work in this range. 5g networks have a range of frequencies ranging from 28 to 38 GHz, and they are not technically capable of providing such high data rates.
In the future, a new generation of chips can be integrated into the communication modules of IoT devices, Autonomous driving systems and multimedia gadgets for streaming data in ultra-high resolution. It is expected that the first commercial devices based on advanced development will appear on the market with the advent of 6G networks.
