Nokia selected to conduct 5G Sub- 6GHz standalone trial in Japan

Nokia has announced it is conducting a 5G standalone ( SA ) network trial with Chubu Telecommunications Company ( CTC ), a subsidiary of KDDI , in Japan .

For the trial , Nokia is supplying its latest AirScale product portfolio and Compact Mobility Unit ( CMU ) to support both 5G indoor and outdoor connectivity .
The trial will utilize a local 5G network which is independent of a traditional mobile network and use the Sub-6GHz ( n79 ) 4.6-
4.9 spectrum band for enhanced capacity . The high-band Sub-6GHz spectrum supports high capacity and extreme mobile broadband capabilities .
The trial will verify how Nokia ’ s 5G SA network can enable CTC to provide commercial high-speed , high-capacity , low latency Fixed Wireless Access services to subscribers without the need for a fiber-optic installation at a customer ’ s home . This is expected to shorten service delivery times .
In this trial , Nokia ’ s 5G SA core was installed at a CTC Lab , and 5G base stations were installed at another CTC Lab and at an apartment complex in Nagoya City . Local 5G networks can be built ahead of time in areas where mobile network services are not yet deployed and have the flexibility to configure the required performance . They are also less susceptible to communication failures or disasters in other locations .
During the trial , CTC will examine the construction and operational processes of installing a 5G Core and 5G base station and verify the application of local 5G including the radio wave propagation characteristics and communication performance in a live environment . The trial will also explore how businesses can utilize the local 5G network to improve the efficiency of solutions such as remote monitoring , video transmission and image analysis .
Kazuhide Yokoi , Director , Corporate Strategy , CTC , said : “ We are delighted to partner with Nokia to unlock local 5G ’ s full potential in Japan . With this trial , our effort is to explore the best of local 5G to deliver a high-speed , best-in-class ultra-broadband experience to our customers while preparing for practical use .”
Donny Janssens , Head of Customer Team , Nokia Enterprise Japan , said : “ We are pleased to be conducting this local 5G standalone network trial together with CTC . Our 5G standalone in the Sub-6 spectrum band will enable CTC to explore new capabilities and revenue opportunities while enhancing its network ’ s operational efficiency . A commercial local 5G SA service will further enable CTC to deliver superior service , capacity and reliability to its customers .” p
