華為完成FDD三頻Massive MIMO全球首商用網速暴增252%

不怕演唱會沒信號：華為、浙江電信宣佈完成FDD Massive MIMO創新商用測試，覆蓋和容量顯著提升

【華為解決5G最大弊端：不怕演唱會沒信號了】近日，浙江電信攜手華為在寧波完成了FDD Massive MIMO的創新商用測試，彰顯了其強大的網絡能力。測試結果顯示，相比傳統4T4R技術，覆蓋能力增強了8dB，下行容量提升至4.7倍，上行容量提升至4.3倍。這一成果意味着，當前城市密集居民區深度覆蓋、海面超遠覆蓋、大型體育場館和演唱會等上下行容量受限的難題，均能得到有效解決。此外，網紅直播、RedCap視聯網和車聯網等大上行需求也將獲得有力支持。華為表示，FDD Massive MIMO強化了多天線技術，不僅更加簡化和綠色，還顯著提升了系統容量。特別是在上行方面，通過大規模智能接收機技術，有效增強了上行覆蓋，並提升了上行MU-MIMO的配對效率，充分滿足移動AI時代對大上行容量的需求。
