不怕演唱会没信号：华为、浙江电信宣布完成FDD Massive MIMO创新商用测试，覆盖和容量显著提升

【华为解决5G最大弊端：不怕演唱会没信号了】近日，浙江电信携手华为在宁波完成了FDD Massive MIMO的创新商用测试，彰显了其强大的网络能力。测试结果显示，相比传统4T4R技术，覆盖能力增强了8dB，下行容量提升至4.7倍，上行容量提升至4.3倍。这一成果意味着，当前城市密集居民区深度覆盖、海面超远覆盖、大型体育场馆和演唱会等上下行容量受限的难题，均能得到有效解决。此外，网红直播、RedCap视联网和车联网等大上行需求也将获得有力支持。华为表示，FDD Massive MIMO强化了多天线技术，不仅更加简化和绿色，还显著提升了系统容量。特别是在上行方面，通过大规模智能接收机技术，有效增强了上行覆盖，并提升了上行MU-MIMO的配对效率，充分满足移动AI时代对大上行容量的需求。
