Japan’s NTT Docomo and Nokia are performing joint 5G technology trials using extremely high frequency 90-GHz millimeter wave (mmWave) spectrum.
At the Brooklyn 5G Summit in New York this week, the companies are demonstrating the use of a Nokia Bell Labs-developed compact mmWave phased-array antenna system using an integrated circuit solution in the 90-GHz frequency band.
The demonstration aims to show how using 5G new radio enhancements at higher mmWave bands can manage radio complexity while enabling greater bandwidth.
Meanwhile using a larger number of antenna elements at higher frequency bands can minimize path loss to enable coverage similar to that found in lower mmWave bands, Nokia said.
The companies also conducted a joint demonstration to show how dynamic offloading relocation in a 5G core will enable the low-latency networks required to support time critical mobile broadband applications such as automation and augmented reality.
Nokia and Docomo have pledged to continue to test these technologies at Docomo’s research lab at the Yokosuka Research Park in Japan.
“These demonstrations at the Brooklyn 5G Summit build on a long collaboration with Nokia,” Docomo CTO Hiroshi Nakamura said.
“Working together, we want to accelerate the evolution of 5G technologies especially towards pioneering higher frequency bands such as 90 GHz.”
