Wi-Fi CERTIFIED™ac提供高達每秒數十億位元的資料速率,使設備能夠處理苛刻的應用,如超高清和4K視頻、多媒體流以及平板電腦、遊戲裝置、手機和許多其他設備上的快速檔案傳輸。 基於IEEE 802.11ac,Wi-Fi CERTIFIED ac設備提供了更高的容量、改進的電源管理和更低的延遲,可輕鬆應對當今苛刻的應用,同時為新產品和服務鋪平道路。

Wave 2功能帶來了Wi-Fi性能的新進展

Wi-Fi CERTIFIED ac通過支援wave 2功能提供更高性能的移動體驗。 最為顯著的是,多用戶多輸入多輸出(多使用者MIMO)允許設備在同一網路上同時運行而不會犧牲速度或性能。增加的速度是通過wave2的特性,如160兆赫通道和4個空間流來支援的。


Wi-Fi CERTIFIED ac建立在Wi-Fi CERTIFIED n的高性能基礎之上,工作頻率為5 GHz,設備可以利用更高的頻寬來實現更高的資料速率。 大多數Wi-Fi CERTIFIED ac產品都是雙頻段,在2.4 GHz和5 GHz頻段都可以使用,並且在2.4 GHz頻段支援Wi-Fi CERTIFIED n。 雙頻帶網路具有雙倍容量,因為設備可以使用不太擁擠的5 GHz頻段用於高性能應用,而2.4 GHz頻段則用於基本需求。


隨著物聯網時代的全面展開和超連接時代的臨近,越來越多的較小型設備相互連接並連接到互聯網。這些設備需要較長的電池壽命。Wi-Fi Alliance推出了節電功能,以使使用者在連接Wi-Fi網路和互聯網時,不用擔心功耗問題。Wi-Fi節電功能提供較長的休眠週期,減少了設備與基礎設施的通信需求。這些功能可極大地降低無數細分市場上Wi-Fi設備的功耗,包括智慧家居、智慧城市、工業和醫療保健市場。

Frequently Asked Questions
  • What is the benefit of MU-MIMO?

    MU-MIMO is an innovative breakthrough that enables simultaneous communication to multiple devices, improving overall speed and enabling network multitasking.

  • How can I upgrade my device to use wave 2 features?

    Upgrading devices to use wave 2 features is implementation dependent. Some devices can be upgraded through software, but most will require new hardware.

  • What performance advances are enabled by Wi-Fi CERTIFIED ac?

    Wi-Fi CERTIFIED ac enables higher data rates, higher capacity and lower latency.  Products implementing the technology behind Wi-Fi CERTIFIED ac with wave 2 features are capable of multi-gigabit data rates– nearly triple that of devices implementing only wave 1 features.

  • What new applications are enabled with Wi-Fi CERTIFIED ac?

    Wi-Fi CERTIFIED ac handles today’s demanding applications and paves the way for new applications in the future.  Certified-ac devices are more robust and offer a greater user experience including:

    • Transferring an HD movie to a tablet in under 4 minutes
    • Sharing photo albums with friends in seconds
    • Streaming three HD quality videos at one time

    Wi-Fi CERTIFIED ac devices also improve wireless performance in the enterprise in the following ways:

    • Enhanced user experience for teleconference meetings
    • Delivering greater in-office networking coverage – more clients for the same number of APs per office area
    • Projecting graphics, video and audio to a large screen in a conference room or auditorium
  • Are Wi-Fi CERTIFIED ac devices dual-band?

    Wi-Fi CERTIFIED ac operates in the 5 GHz band, but devices support the 2.4 GHz band by integrating Wi-Fi CERTIFIED n.  Dual-band devices switch between the more crowded but popular 2.4 GHz frequency band, to the cleaner 5 GHz frequency band to connect more demanding applications and avoid interference from other devices.

  • Is Wi-Fi CERTIFIED ac interoperable with previous versions of Wi-Fi?

    As with all Wi-Fi CERTIFIED devices, Wi-Fi CERTIFIED ac products are tested to ensure interoperability with legacy Wi-Fi CERTIFIED products. Products must operate in the same frequency band in order to connect.

  • What is WMM?

    Wi-Fi CERTIFIED for WMM (Wi-Fi Multimedia) provides multimedia enhancements for Wi-Fi networks that improve the user experience for audio, video, and voice applications.

  • How does Wi-Fi Alliance help ensure product compatibility and a good user experience for certified products?

    Compatibility and quality are achieved through rigorous testing of Wi-Fi products. Consumers should always look for the Wi-Fi CERTIFIED logo to ensure the best user experience possible.
