基于建筑物特征的5G 2.6 GHz多通道设备选型原则

The principle for antenna selection of 5G 2.6 GHz based on building features

作为满足高数据速率e MBB业务场景的5G关键技术之一,大规模天线技术对天线能力提出了更高的要求。国内运营商已有最大64通道的5G2.6 GHz宏站设备,通过Massive MIMO提供优异的网络性能。为了降低CAPEX和OPEX压力,满足部分天面空间受限场景需求,运营商引入了32通道和8通道设备,灵活适配多种场景。为了确保不同建设场景中设备选型的合理性,本文结合理论分析和仿真研究给出了基于建筑物特征的5G 2.6 GHz多通道设备选型原则。

As one of the key 5G technologies to meet high data rate e MBB scenario, large-scale antenna technology places higher requirements on antenna capabilities. China telecom operator already has the largest 64 TRX 5G 2.6 GHz AAU, which provides excellent network performance through Massive MIMO. In order to control the CAPEX and OPEX and meet the needs of some limited space scenarios, mobile operator introduced 32 TRX AAU and 8 TRX antenna to fl exibly adapt to various scenarios. In order to ensure the rationality of equipment selection in different construction scenarios, this paper combined with theoretical analysis and simulation research to give the principle for antenna selection of 5G 2.6 GHz based on building features.
