Nokia and KDDI have conducted what they claim is a first for Japan –a trial simulating future 5G network demands, providing gigabit connectivity inside an apartment block using Nokia radio technology on the 28-GHz band.

The trial, conducted between the KDDI Research Building and an apartment approximately 100 meters away, achieved speeds in excess of 1 Gbps using Nokia’s AirScale RAN, demonstrating how 5G technology can be used inside apartment blocks to meet demand for wireless ultra-broadband services like Ultra HD video in densely populated megacities such as Tokyo.

The trial took place in Fujimino City of Saitama Prefecture and marks the first in a series of 5G collaborations between Nokia and KDDI following the signing of a Memorandum of Understanding (MoU) last year.

“The speeds achieved in this trial show great potential for us to deliver high-quality services,” said Akira Matsunaga, senior director of Mobile Network Technical Development at KDDI. “Working with Nokia, we want to develop the use of technologies that deliver on the promise of 5G to meet our subscribers needs.”

“This trial is an important milestone both in our collaboration with KDDI and in our development of technology to meet the ever-growing demands of the large populations of megacities,” said Jae Won, head of Nokia Japan. “5G promises to deliver the ultra-low latency, capacity and high speeds for these types of deployments.”
