NEC and ADI Collaborate to Provide 5G O-RAN Massive MIMO Radio Solutions for Rakuten Mobile
The radio unit uses
ADI's
fourth-generation wideband
RF
transceiver solution to achieve high-precision massive
MIMO
and has
a
5G
open
vRAN
(virtual radio access network) interface to
meet
Rakuten Mobile's
end-to-end fully virtualized cloud-native mobile network needs
,
achieving efficient high-capacity transmission
through
3.7GHz
massive
MIMO
and digital beamforming technology
. Cloud-native virtual networks herald a major shift in how communications service providers will provide high-speed Internet
access
worldwide at significantly lower costs
and, as much as possible, without the maintenance, upkeep, repair and labor costs associated with physical infrastructure, which are the factors that hinder
the development of
traditional
networks.

ADI's fourth-generation wideband RF transceiver integrates four-channel transmitters, receivers, and digital pre-distortion (DPD) in one chip. The radio solution can be fully reconfigured through software and covers all sub-6GHz 5G frequency bands, simplifying radio design.
“ADI’s RF transceivers are specifically designed to support wireless applications such as massive MIMO and small cell systems, simplifying system design, reducing size and weight, and minimizing power consumption,” said Nozomu Watanabe, senior vice president of NEC Corporation . “Virtualization is a reliable and cost-effective technology that the world’s leading telecommunications providers are exploring as the next evolution in communications. ADI’s RF devices enable us to provide the connectivity technology needed to build the architecture that supports the full spectrum of 5G systems.”
NEC's 5G equipment utilizes high-precision digital beamforming to achieve efficient, high-capacity transmission. The system also enables seamless installation through circuit integration.
“The next wave of 5G connectivity is defined by flexibility, and by working with NEC to develop the first Massive MIMO device for Rakuten Mobile, we are laying the foundation for 5G connectivity moving forward,” said Greg Henderson, senior vice president, Analog Devices. “This ecosystem is complex, but the main goal is to have all parties work together seamlessly to improve overall efficiency in terms of cost, time, and capital equipment. These links will help us move closer to a truly virtualized network.”
