Researchers believe there are more spectrum options for next-generation 6G networks than previously thought.
5G commercial networks launched in 2019 with promises of lower latency and faster data speeds. To extend this functionality, it is believed that 6G networks will need to use the higher frequency Terahertz bands.
However, at higher frequencies, these waves become more difficult to handle, making it easy to lose connection.
New algorithms must also be developed that allow processing on the new bandwidth and completely new hardware must be designed that can function in this new zone.
A team from the University of Southern California (USC) conducted tests on proposed 6G frequencies to address these challenges.
They try to learn enough about the nature of each frequency and then develop new devices that will work in it.
Andy Molisch, USC professor of electrical and computer engineering, explained that their early work suggests we have more options for communication on 6G frequency than previously thought.
His team conducted a series of highly detailed measurements on possible 6G frequencies that yielded some “surprising” results that will help design next-gen networks.
“Researchers have long believed that as we move to the 6G frequency, the ways a signal can reach a receiver will be very limited,” Molisch said. “Our work shows that in a number of key situations this is not really the case.
” He added that a lot more work needs to be done before they can start building practical tools that work in this space.
“Our first round of measurements has been extremely successful so far, but many more measurements need to be done before we understand enough to communicate on these frequencies to make 6G a daily reality,” he said.
The team identified three technologies that could be enabled with 6G networks: haptic internet, mobile edge computing and holographic communications.
All three of these areas have the potential to change the face of communication, health, transportation, education and more, the researchers said.
