製造企業一直是網絡攻擊犯罪分子的首選目標。據統計在2020年第一季度，針對製造業的勒索軟件攻擊增加了156％，而同期各行業平均僅增長了25％。造成這一局面的原因有很多，其中關鍵的一條是負責生產技術(OT)和負責信息技術(IT)的兩個團隊沒能很好地協作。 IT團隊有豐富的網絡安全實戰經驗，但因為很多生產設備難於接入企業網絡，所以一旦遇到產線遭攻擊的事故往往束手無策。而網絡安全又不是OT團隊的業務重點，據IBM針對370家工業企業的調研，74%的受訪者沒有進行OT風險評估，78%的受訪者沒有OT特定的安全策略，還有81%的受訪者沒有OT特定的安全事件響應計劃。所以為企業提供能融合IT和OT團隊的工具，搭建覆蓋產線、辦公等的企業全方位網絡安全保護傘既是關係企業當下運營的關鍵，也是未來推進智能製造轉型的基礎。

2020 年 4 月，聯邦通信委員會 (FCC) 通過關於 6 GHz 頻段無線操作的新規定，為非授權設備開放 1200 MHz 頻譜的使用。這是自 1989 年以來批准的最大一次 Wi-Fi 頻譜擴充。 6 GHz 頻段的開放使 Wi-Fi 可用頻譜增加了一倍多，可減少無線電波擁塞、增加信道寬度、提高連接速度，使各行業的一系列創新成為可能。自 FCC 決定開放 6 GHz 頻段以來，有 70 個國家/地區（覆蓋 34 億人口）已經批准或正在考慮制定關於 6 GHz 的法規（來源：Wi-Fi-Alliance）
