The new technology can triple the data transfer rate.
A new study presents a technology capable of tripling data transfer speeds in wireless networks, which could be a significant step in the development of 6G communications. Researchers at Cornell University (Ithaca, New York) have developed microchips equipped with three-dimensional stacks of reflectors that promise increased throughput through the use of spiral waveguides.
Current wireless technologies, including 5G, operate at frequencies below 6 GHz. The new development is aimed at using frequencies above 20 GHz to achieve data transfer speeds that exceed 5G by a hundred times. The main problem associated with high 6G frequencies is an increase in signal loss due to attenuation caused by environmental influences. Traditionally, phase shifters are used to compensate for signal delays, but they are inefficient over wide frequency bands and can cause signal blurring.
The new component developed by Bala Govind's team is a reduced true time delay element measuring only 0.16 square millimeters, which is smaller than that of phase shifters. This component can evenly delay all frequencies in the 14 GHz bandwidth, avoiding problems with signal blurring. The achievements were made possible by the use of three-dimensional spiral reflectors, which provide a delay of signals due to their three-dimensional movement in stacks.
Using such devices in arrays with a bandwidth of 8 GHz can provide data transfer speeds of more than 33 gigabits per second, which is three times the capacity of phase shifters and 40% higher than the existing true time delay elements. In addition, the proposed approach can be applied in optical and acoustic fields.
The results of the study were published this week in the journal Nature, highlighting the importance of development for the future of wireless communications and the potential to significantly accelerate the development of 6G technologies.
