Passpoint

无缝、安全地连接到Wi-Fi®网络

Wi-Fi CERTIFIED Passpoint®是一种适用于全行业的解决方案,可简化Wi-Fi接入,且无需用户每次访问网络时都进行寻找网络和验证身份的操作。Passpoint接入点(AP)几乎可以部署在从零售商店到企业、酒店、机场、体育场等大型运营商网络环境的任何地方。

一旦用户接入了某个场所提供的Wi-Fi网络,那么之后用户再次访问这个网络时,支持Passpoint的客户端设备就会自动连接。用户无需在每次访问该网络时,都再次搜索和选择网络、请求Wi-Fi接入并重新输入验证证书。Passpoint实现了整个流程的自动化,因此在Wi-Fi网络和移动设备之间实现了更加无缝的连接,与此同时还可提供企业级安全性。Passpoint配置通过建立证书信息以及向移动设备提供政策信息,可支持(有或没有SIM卡的)新设备入网。

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.
