Passpoint

無縫、安全地連接到Wi-Fi®網路

Wi-Fi CERTIFIED Passpoint®是一種適用于全行業的解決方案,可簡化Wi-Fi接入,且無需使用者每次訪問網路時都進行尋找網路和驗證身份的操作。Passpoint接入點(AP)幾乎可以部署在從零售商店到企業、酒店、機場、體育場等大型運營商網路環境的任何地方。

一旦使用者接入了某個場所提供的Wi-Fi網路,那麼之後使用者再次訪問這個網路時,支援Passpoint的用戶端設備就會自動連接。使用者無需在每次訪問該網路時,都再次搜索和選擇網路、請求Wi-Fi接入並重新輸入驗證證書。Passpoint實現了整個流程的自動化,因此在Wi-Fi網路和移動設備之間實現了更加無縫的連接,與此同時還可提供企業級安全性。Passpoint配置通過建立證書資訊以及向移動設備提供政策資訊,可支援(有或沒有SIM卡的)新設備入網。

Frequently Asked Questions
  • How does Passpoint support service provider branding and customer relationships?

    Passpoint enabled mobile devices can choose networks based on a list of preferred (direct or partner) providers, specific services and/or the best performance characteristics. For service providers offering a managed experience, seamless authentication is a valuable element, and Passpoint networks also support deployments where a click-through screen is essential for acceptance of terms and conditions or branding.

  • How does Passpoint equipment support Wi-Fi roaming?

    Passpoint devices use industry-agreed uniform mechanisms for discovering and creating secured connections to hotspots. This allows a subscriber to experience seamless Wi-Fi connectivity to a hotspot anywhere in the world a user’s provider has roaming agreements. Passpoint is specified as a requirement for the Wireless Broadband Alliance’s industry work on Wi-Fi roaming.

  • What standards does Passpoint draw on?

    Passpoint makes use of elements of IEEE 802.1X, 802.11u, 802.11i, and WPA3™-Enterprise security, as well as some Wi-Fi Alliance defined mechanisms.

  • Who created the Passpoint program?

    Members of Wi-Fi Alliance created the program. The group which developed Passpoint includes service providers, mobile operators, fixed line operators, and makers of mobile devices and infrastructure equipment.

  • What does Passpoint mean for end users?

    Passpoint provides a better Wi-Fi user experience while mobile. Users with certified Passpoint devices can enjoy the benefits of streamlined network selection and secure connectivity at Passpoint enabled hotspots. Passpoint-enabled devices operate based on user preference.

  • What does Passpoint bring to hospitality?

    Hospitality chains may own many brands but a single consolidated rewards program. Without Passpoint, either the rewards program SSID needs to be added at every hotel or users’ phones must be configured with several SSIDs. Passpoint can function with a single profile that identifies the rewards program instead of a hotel SSID. When a user visits an associated property, their device will automatically identify the access point and connect.

  • Can existing equipment be upgraded for Passpoint?

    The hardware and software platform of a given device determines whether it can be upgraded in the field. Equipment that has previously undergone certification testing can be updated and resubmitted for Passpoint certification.

  • Can legacy clients join a network with Passpoint access points?

    Legacy mobile devices can connect to Passpoint access points configured for open system authentication, although they will not enjoy Passpoint features for network selection, automatic authentication, or expanded security. A user connecting to an open network with a legacy mobile device will manually find the available networks and then select and connect to the preferred network.

    The access points used in hotspot and enterprise networks are often configured to support multiple SSIDs (networks) on the same equipment; a configuration that offers a Passpoint-certified network and a separate open network allows Passpoint mobile devices to enjoy the full benefits while supporting legacy clients.

  • Does Passpoint support voice over Wi-Fi?

    The scope of Passpoint testing is to ensure that the mechanisms for seamless discovery and creation of a secured link are implemented correctly. It is application-agnostic.

  • What types of equipment are tested for Passpoint?

    Infrastructure equipment such as access points, and mobile and portable devices such as smartphones, tablets, and notebooks have been certified. Passpoint is available on both SIM and non-SIM Wi-Fi devices.

  • Are Wi-Fi CERTIFIED products protected by security?

    As of July 1, 2020, all new Wi-Fi CERTIFIED devices require WPA3. The only way to be sure that a product meets the latest security standards is to purchase only Wi-Fi CERTIFIED products.

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

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