Fujitsu to deliver O-RAN compliant radio units for KDDI's 5G rollout using virtualized base stations

摘要

Fujitsu has announced that its O-RAN compatible 5G Radio Unit has been selected by KDDI (au) for the construction of virtualized base stations for 5G commercial services in Japan, with planned delivery in the second half of FY 2021. In a press release the vendor outlined that its 5G Radio Unit takes advantage of 'O-RAN standard specifications for fronthaul interface for communication with base station controllers (CU: Central Unit/DU: Distributed Unit)'. It claims that this design makes it possible 'to establish a flexible network with an O-RAN configuration by connecting base station controllers between different vendors that comply with this specification'. Further, it goes on to note that: 'Fujitsu will make miniaturization and low power consumption a reality for Radio Units that utilize highly-efficient, wide-band power amplification technology. Mounting more antenna elements than conventional MIMO (Multi Input Multi Output) technologies enhance the effects of beamforming and spatial multiplexing and will ultimately help to deliver seamless, speedy mobile communications for users in places where many people gather.'
