Nokia and NTT DOCOMO test 5G using 90 GHz

Nokia and NTT DOCOMO will undertake a joint study and trials on 5G using 90 GHz frequencies.

Nokia Bell Labs has already tested a first phased-array RF chip solution for the 90 GHz band to increase radio coverage in higher frequency bands and deliver multi-gigabit speeds at scale.

At this week's 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 path loss 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.

Marcus Weldon, President of Nokia Bell Labs, said: "At Bell Labs, we work with leading operators such as NTT DOCOMO to develop disruptive technologies that will redefine human existence. At the Brooklyn 5G Summit, we will show the world's first RF solution that addresses the challenge of delivering optimized coverage for future mmWave frequencies, using a pioneering RFIC design that can be scaled to any array dimension and deliver optimized connectivity to any set of devices."

NTT DOCOMO Tests Solar Base Stations

NTT DOCOMO is launching field tests of three conventional mobile-network base stations that have been installed with solar panels, high capacity rechargeable batteries and green power controllers.

NTT DOCOMO will install 10 green base stations in the Kanto-Koshinetsu region of Japan by late summer, including the first three in Tokyo, Kanagawa and Yamanashi prefectures. The equipment was already by tested at its R&D Center from March 2012 to February 2013. 

The green base stations use solar panels to generate and store solar power during the daytime. If commercial power supply is cut off during a disaster, the station can rely solely on this power to run communication equipment during the day and use high-capacity, rechargeable batteries to store 14-16 hours’ worth of power when solar power is not available.

The solar panels to be used in the field test generate up to 4.19 kW, whereas the maximum power consumption of a base station is 2.0 kW. Remotely controlled green power controllers will manage power used by the base stations, including utility-provided electricity, solar panel-generated electricity, and high-capacity, rechargeable batteries that discharge their energy as required.

The company said its interest in disaster-proof, environmentally friendly base stations was spurred by the Great East Japan Earthquake.  NTT DOCOMO is also considering fuel cell technologies and wind-powered base stations.
