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.
