Nokia and KDDI (au) have embarked on a joint initiative aimed at delivering a fully virtualised Cloud RAN solution. In a press release the Finnish vendor confirmed the start of a lab-based proof of concept (PoC), using its AirScale All-in-Cloud BTS solution, to enable the Japanese cellco to research ‘how flexible, virtualised radio network technology can support the diversifying network performance requirements in the 5G era’. Nokia claims its AirScale All-in-Cloud BTS is a ‘fully cloudified 5G BTS, placing both the real-time and non-real-time baseband in the cloud’. With KDDI having launched commercial 5G services in March 2020, the PoC will be used to provide a flexible network configuration of a base station virtualisation as KDDI strives to implement an ‘optimal’ 5G network. The statement also noted that the Japanese carrier has also been working closely with Nokia on 5G core standalone network trials.
