Using digital beamforming technology
Efficiently transfer large amounts of data
Covers all 5G frequency bands below 6GHz


Analog Devices and NEC Corporation announced on the 23rd that they have designed Rakuten Mobile's 5G network Massive MIMO antenna radio unit (RU).
This wireless device uses Massive MIMO and digital beamforming technology at a frequency of 3.7 GHz to transmit large amounts of data with excellent efficiency.

By eliminating the maintenance, upkeep, and labor costs associated with physical infrastructure that disrupts existing networks, cloud-native virtual networks enable telecommunications carriers to provide high-speed internet access globally at lower costs. NEC has already begun shipping its 5G network Massive MIMO antenna RU to Rakuten Mobile.

Additionally, ADI's fourth-generation wideband RF transceiver integrates a quad-channel transmitter, receiver, and Digital Pre-Distortion (DPD) on a single chip. This RF product is fully software reconfigurable and covers all 5G frequency bands below 6 GHz, significantly simplifying wireless design.

“ADI’s RF transceivers are designed to simplify system design, reduce size and weight, and minimize power consumption,” said Nozomu Watanabe, Senior Vice President at NEC. “They support 5G full-spectrum systems and provide the connectivity required to build the architecture.”

“The next wave of 5G-based network connectivity is all about flexibility,” said Greg Henderson, senior vice president at Analog Devices. “We are laying the foundation to accelerate 5G connectivity and help move to the next phase of truly virtualized networks.”
