Nokia demonstrates potential of 28GHz in built-up areas

News

Nokia has embarked on its latest 5G trial, teaming up with Japanese operator KDDI to test how 28GHz spectrum can deliver high speeds in built up areas.

The trial in Fujimino City used Nokia's AirScale radio and achieved speeds of 1GBps between KDDI's research building and an apartment complex 100 metres away.

Akira Matsunaga, Senior Director, Mobile Network Technical Development, KDDI, said: "The speeds achieved in this trial show great potential for us to deliver high-quality services."

Jae Won, Head of Nokia Japan, added: "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.

"5G promises to deliver the ultra-low latency, capacity and high speeds for these types of deployment, and this trial is a great example of how it can be applied to transform the entertainment experience as one of the many use cases 5G has to offer."

Both companies signed a memorandum of understanding last year to research various 5G technologies. Nokia said the results helped show how operators could meet demand for high speed and quality mobile broadband in "megacities" such as Tokyo.

In March, Ericsson partnered with Japanese operator Softbank to also show how 28GHz could operate by using mmwave technology.

The Swedish operator used the same band in a separate test with IBM in February.
