Wi-Fi Optimized Connectivity

提升網路移動性

Wi-Fi CERTIFIED Optimized Connectivity™–是Wi-Fi CERTIFIED Vantage™的一個關鍵組成部分。它是一項Wi-Fi Alliance® 認證計畫,通過減少傳輸時間開銷以及對所選接入點進行更快的身份驗證,來提升網路移動性,並在使用者網路內或跨網路漫遊時為其提供更穩定的網路連接。Wi-Fi Optimized Connectivity™使用戶在整個漫遊過程中體驗高品質的網路連接,由於接入點和用戶端設備可以實現資訊交換,以下主要益處得以實現:

優化網路發現與選擇:移動端和接入點採用改進的通道掃描技術,快速識別潛在的可供連接Wi-Fi® 網路。

鏈路品質評估:基於雙向鏈路品質估計與網路拓撲資訊,為用戶端設備提供指標,協助其迅速做出決定,選擇能夠提供最佳連接的接入點。

快速身份驗證:使用快速初始連結設置(FILS)身份驗證,設備可以協同工作以減少傳輸時間開銷,並對所選接入點或網路進行更快的身份驗證。

高效傳輸:顯著減少管理幀傳輸,使設備能夠用更少的時間回應管理資訊,用更多的時間傳輸使用者資料。

運行中的Wi-Fi Optimized Connectivity

一項現場測試表明,使用Wi-Fi Optimized Connectivity關鍵元件的設備比那些未通過這些技術認證的設備性能更好。使用Wi-Fi Vantage™功能來增強網路發現和高級漫遊,結果顯示相較於未獲得Wi-Fi 優勢認證的Wi-Fi設備,這些設備的設置時間減少了76%,管理幀和信標擁堵平均減少了76%,性能顯著提高。執行測試的服務提供者能夠高效的管理網路資源,容納更多的設備,提供更高的客戶滿意度。終端使用者可以體驗更快的連接,更加穩定的語音、視頻通話。

Wi-Fi Optimized Connectivity和Wi-Fi 6E

Wi-Fi Optimized Connectivity功能也是6GHz頻段高效的發現網路接入點的關鍵因素。同時運行2.4GHz頻段或5GHz頻段以及6GHz頻段的Wi-Fi 6接入點——也被稱為Wi-Fi 6E——在2.4 GHz和,或5 GHz頻段傳輸一個減小鄰居報告元素,來實現6GHz基本服務集合(BSSs)的頻外探查。為了最大限度地提高頻譜效率和利用率,同時在多個頻段運行的接入點都默認將禁用6GHz頻段的FILS發現幀和主動探測響應幀。僅在6GHz頻段運行的接入點傳輸FILS發現幀或者主動回應探測幀,從而實現高效的頻道掃描。對於那些運行於其他頻段和通道的BSSs,尤其是那些對主動掃描有監管限制的動態頻率選擇通道,Wi-Fi Optimized Connectivity接入點可以使用相同的功能來實現高效探查。
