The success of the metaverse is going to need improvements in 5G and 6G technologies, says Jonathon Wright, UK based Chief Technologist for Keysight at the Keysight World Innovate today.
The key is getting sufficient bandwidth and low enough latency over global networks that can include satellite links. This will require new compression and transmission technologies in the 6G standards currently being developed.
Keysight is talking to several developers of lightweight augmented reality (AR) glasses for metaverse applications.
“20ms latency motion to photon defines the metaverse today and that provides a bandwidth and latency challenge for satellite, particularly in a 3D space,” he said. He points to the latency requirements of eye tracking in the latest Apple Vision Pro AR headset and the needs of remote surgery as key examples.
“This is beyond the 5G potential and we are looking to 6G to solve the challenge around the metaverse for aerospace and defence and emergency services,” he said.
Back in April, Keysight was part of the UK’s first 100Gbit/s sub-terahertz wireless link demonstration., The link was developed with the National Physical Laboratory and the University of Surrey running at 300 GHz using both 32 and 64 quadrature amplitude modulation on Keysight’s 6G sub-THz testbed platform at NPL.
The testbed uses the M8194A Arbitrary Waveform Generator (AWG) combined with Virginia Diodes (VDI) upconverters / downconverters to generate the signal and Keysight’s UXR0704A Infiniium multichannel high-performance 70 GHz oscilloscope to analyze the signal.
“6G is a key focus for NPL and we are using our scientific and measurement capabilities to tackle the challenges of this new technology. Our partnership with Keysight will be a critical success factor in our 6G research work,” said Irshaad Fatadin, Principal Scientist, National Physical Laboratory.
