NEC：ADI公司，大规模（ADI）
我们为乐天移动共同开发了用于5G基站设备无线电的Massive MIMO天线。
大规模MIMO天线：
ADI公司的第四代宽带RF收发器解决方案用于实现高精度的大规模MIMO。
该5G无线电与Rakuten Mobile的“端到端完全虚拟化云原生移动网络”兼容。
配备5G开放式vRAN接口。
5G开放vRAN接口：
3.7GHz大规模MIMO * 1（超多元素天线），
采用数字波束成形技术* 2形成高精度光束
高效率地实现大容量传输。
降低电信运营商成本的优势：
运营商位于传统网络的物理基础设施上。
维护管理
保持，
修理，
人事费用等
通过消除负担，成本大大降低。
NEC已开始为Rakuten Mobile发售该产品。

NEC and Analog Devices Collaborate to provide a 5G O-RAN Massive MIMO Radio for Rakuten Mobile:
Norwood, MA and Tokyo, Japan –
October 23, 2020 –
NEC Corporation (NEC) and Analog Devices, Inc. (ADI)
announced today that they have teamed up to design a 5G Network Massive MIMO Antenna Radio Unit for Rakuten Mobile.
The radio unit
adopts ADI’s fourth-generation wideband RF transceiver solution to achieve high precision Massive MIMO
possesses a 5G open vRAN (virtual RAN) interface corresponding to Rakuten Mobile’s end-to-end fully virtualized cloud-native mobile network.
It delivers large capacity transmission with high efficiency by using 3.7GHz frequency Massive MIMO*1 and digital beamforming technology.*2
The cloud-native virtual network
heralds a major shift in how communications providers can offer high-speed internet access worldwide, at significantly lower costs,
made possible without the maintenance, upkeep, repair and labor costs associated with the physical infrastructure that hinders conventional networks.
NEC
has already started shipping the 5G Network Massive MIMO Antenna Radio Unit to Rakuten Mobile.
