Hotspot 2.0 & Passpoint offload and roaming planner
Model cellular data offload capacity, IEEE 802.11u ANQP query rates, and zero-touch auto-connect retention across enterprise AP hardware.

Model cellular data offload capacity, IEEE 802.11u ANQP query rates, and zero-touch auto-connect retention across enterprise AP hardware.
Hotspot 2.0 (based on IEEE 802.11u) is a wireless networking standard that allows mobile devices to automatically discover and evaluate access points prior to association. Using Access Network Query Protocol (ANQP), client devices query network capabilities, cellular roaming consortia, and realm identity parameters before transmitting association frames, enabling instant zero-touch roaming without manual SSID selection.
Hotspot 2.0 is the underlying IEEE 802.11u wireless standard. Passpoint (WiFi CERTIFIED Passpoint) is the industry certification program that validates device and access point interoperability. OpenRoaming, developed by the Wireless Broadband Alliance (WBA), is the global roaming federation that connects identity providers (telecom carriers, identity platforms, universities) with venue networks using Passpoint as the underlying radio standard.
Standard public captive portals use unencrypted open SSIDs that transmit data frames in cleartext, exposing users to eavesdropping and rogue AP attacks. In contrast, Passpoint mandates WPA2 or WPA3-Enterprise 802.1X authentication. Every client session generates unique cryptographic session keys via EAP-TLS or EAP-TTLS, providing encrypted over-the-air protection across public and guest venues.
High-density venues like stadiums and airports suffer from macro-cell cellular spectrum congestion. Hotspot 2.0 enables mobile network operators (MNOs) to automatically authenticate subscriber SIM credentials (EAP-SIM or EAP-AKA) or provisioned eSIM profiles onto enterprise WiFi networks. This offloads high data volume from saturated LTE and 5G cellular towers while providing visitors with high-speed connectivity.
Most modern enterprise wireless hardware vendors support Hotspot 2.0 Release 2, including Cisco Catalyst 9800, Cisco Meraki MR, HPE Aruba Central, Ruckus SmartZone, Juniper Mist, and Fortinet FortiAP. Network administrators configure 802.11u ANQP parameters, NAI Home Realms, and Roaming Consortium Organization Identifiers (RCOIs) directly within controller WLAN templates.
Yes. Venues can broadcast a dual-layer strategy. First-time visitors without a Passpoint profile connect via a standard branded captive portal to complete registration and accept terms. During onboarding, the Purple platform pushes an encrypted Passpoint profile or provisioning link to the user's device, enabling all subsequent visits to auto-connect with zero splash screen friction.
