Nokia and NTT DOCOMO Conducting 5G Trials in the 90 GHz Band

At the Brooklyn 5G SummitNokia and NTT DOCOMO are showcasing 5G technology innovations that will deliver massive-capacity to address the increased demand in video data and other applications.

They are working together to create technologies that will support the delivery of enhanced mobile broadband applications for 5G. The widespread availability of applications such as real-time virtual and augmented reality video will enable new capabilities for both industries and consumers. Delivery will rely on ultra-responsive networks with massive wireless capacity in dense deployment scenarios.

At the Brooklyn 5G Summit, Nokia, supported by NTT DOCOMO, will show two technology innovations being developed to address these demands:

  • The companies will apply a Nokia Bell Labs-developed compact mmWave phased-array antenna system scalable up to 256-elements using an integrated circuit (RFIC) solution in the 90 GHz frequency band to enable multi-gigabit per second speeds. The test will demonstrate how using 5G New Radio (5G NR) enhancements at higher mmWave frequency bands can manage radio complexity and a larger number of antenna beams, while enabling greater bandwidth. It will also show how using a larger number of antenna elements at higher frequency bands can minimize pathloss to enable coverage similar to that found using lower mmWave bands.
  • A joint demonstration will also show how dynamic offloading relocation in a 5G core will enable the low-latency networks required to support time critical mobile broadband applications for future automation and augmented reality.

Nokia and NTT DOCOMO will continue to test these technologies in NTT DOCOMO's research lab at the Yokosuka Research Park in Japan. The companies will investigate how the Nokia Bell Labs developed RFIC solution operating in the 90 GHz frequency band will enhance coverage in a variety of scenarios, including urban, suburban and in-building environments to meet the massive connectivity demands of consumers and businesses in Japan.
