使用WiFi 6E的朋友們需要注意，AFC for 6GHz 是必要的喔，尤其是高功率的產品，自动频率协调的功能，可以避免干擾現有的6GHz頻段的使用者。
再加上Steering KPIs for EasyMesh 2.0，Client可以在2.4G, 5G以及6G 頻帶上steering，load balancing可以做得更好，系統也更加穩定。
RTT Support AP mode, 可讓產品多了支援室內定位的附加功能，對於較大型的室內空間來說，定位功能不能依賴GPS，RTT 對於EasyMesh來說，會是個很好的賣點。
SPF 11.5 可以有更佳的WiFi 6E以及EasyMesh使用者體驗。
AFC的加入，MBSSID的優化，WLAN Host模組化，加強對non-EMA clients的使用，多個功能在對6GHz的優化，說明SPF11.5之後，才真正的是 WiFi 6E 完整實現，是WiFi 6E的終極版本。高通SPF11.x的Roadmap
