Hotspot

Wifi passpoint(hotspot 2.0)

Definition: A Wi-Fi hotspot is a physical location or device that provides wireless internet access to users, typically through a local area network (LAN) connected to a router. It can be created using a mobile device (mobile hotspot) or a dedicated router.
Authentication: Users typically need to manually connect to a hotspot by selecting the network (SSID) and entering a password.
User Experience: The connection is often temporary. Users must re-authenticate every time they connect to the hotspot.
Security: Hotspots generally offer open or password-protected networks. Open networks (like those in public places) can be less secure, exposing users to potential threats unless extra protection (like a VPN) is used.
Use Cases: Public places like airports, cafes, or personal hotspots created using a smartphone.

Definition: Wi-Fi Passpoint is a technology that automates the process of connecting to secure Wi-Fi networks. It was developed by the Wi-Fi Alliance under the Hotspot 2.0 standard, making the connection process more seamless, secure, and automated.
Authentication: Passpoint networks use automatic authentication, often linked to a user’s cellular carrier, credentials stored on a device, or SIM card. Users don’t need to manually select the network or enter credentials each time.
User Experience: Once a device is configured to use Passpoint, it can automatically connect to available Passpoint-enabled Wi-Fi networks, providing a seamless and roaming-friendly experience similar to how mobile networks operate.
Security: Passpoint uses advanced encryption standards (WPA3 or WPA2-Enterprise), ensuring a higher level of security than typical public hotspots. It also supports seamless authentication via EAP (Extensible Authentication Protocol).
Use Cases: Common in places like airports, hotels, or city-wide networks where secure, automatic roaming is desired. Cellular carriers and ISPs also use Passpoint to offload traffic from mobile networks to Wi-Fi.
