The fifth-generation wireless communications standard, or 5G, is still in the process of being rolled out around the world, but engineers from the University of California, Irvine, (UCI) have already bested the technology.
A wireless transceiver in the form of a 4.4 mm2 silicon chip, the device operates in the 100 GHz range, allowing it to process signals faster and with greater energy efficiency than 5G, which uses the 28 to 38 GHz range.
To circumvent physical limits to digital processing, the technology uses a design that allows it to modulate digital bits differently.
“We call our chip ‘beyond 5G’ because the combined speed and data rate that we can achieve is two orders of magnitude higher than the capability of the new wireless standard,” said Payam Heydari, Professor of Electrical Engineering and Computer Science at UCI and senior author on a paper describing the research.
“In addition, operating in a higher frequency means that you and I and everyone else can be given a bigger chunk of the bandwidth offered by carriers.”
