Electrical Engineers at UCI Develops New Wireless Transceiver Faster Than 5G

Electrical engineers on the University of California, Irvine (UCI) have invented a unique wireless transceiver that will increase radio frequencies into the 100-gigahertz territory, which is four times the pace of the upcoming 5G wireless communications standard.

The 4.4-mm2 silicon chip, dubbed “end-to-end transmitter-receiver” by its creators in UCI’s Nanoscale Communication Integrated Circuits Labs, can process digital signals more energy-efficiently and more rapidly. This may be attributed to its unique digital-analog structure. The latest breakthrough has been reported in the IEEE Journal of Stable-State Circuits.

In response to the NCIC labs director, Heydari, communications circuit engineers and academic researchers have long wished to find out whether or not wireless techniques are capable of the high pace and efficiency of fiber-optic networks.

His group’s solution is a single transceiver that leaps significantly over the 5G wireless standard—chosen to operate inside the 28 to 38 GHz range—into the 6G standard, which is assumed to operate at 100 GHz and above.

It will quickly become vital to have receivers and transmitters that can handle such high-frequency data communications and thus bring in a unique wireless generation managed by autonomous autos, the “IoT,” and vastly expanded broadband for streaming of various subtle technologies, including HD video content.

Although this virtual dream has driven technology builders for many years, obstacles have started to emerge on the path to progress.

Heydari stated that various frequencies of signals via demodulation and modulation in transceivers have been traditionally done via digital processing. Nevertheless, built-in circuit engineers have begun to see the physical constraints of this strategy.

So as to resolve this problem, researchers at NCIC Labs employed a chip architecture that significantly relaxes the requirements of digital processing by changing the digital bits in the radio-frequency and analog domains.
