What does passpoint do

connecting to Wi-Fi networks, particularly public hotspots.It allows users to automatically and securely connect to Wi-Fi networks without needing to manually select SSIDs or enter credentials each time they connect to a new network

Process

• Automatic Network Selection

  • Devices equipped with Passpoint can automatically discover and connect to available Wi-Fi networks that meet specific security and performance criteria. This eliminates the need for users to manually search for and join a network.

• Seamless Roaming

  •  Passpoint supports seamless roaming between networks, allowing users to move from one hotspot to another (e.g., from a coffee shop to an airport) without having to log in again.

• Enhanced Security

  • Passpoint requires the use of WPA2-Enterprise (and more recently WPA3) security, which provides better encryption and authentication compared to open networks. It uses Extensible Authentication Protocol (EAP) for authentication, enhancing security for users.

• Authentication via SIM, Certificates, or Username/Password

  • Passpoint supports multiple methods of authentication, including:

• • • SIM-based authentication(for cellular subscribers),

    • Certificate-based authentication

    • Username and password authentication (e.g., credentials provided by an internet service provider).

• Efficient Data Management

  •  By prioritizing Wi-Fi over cellular networks for data traffic, Passpoint can reduce mobile data usage, particularly in areas with strong Wi-Fi coverage.

Use cases

• Public Hotspots

  • Passpoint is widely used by public Wi-Fi providers, such as airports, hotels, and cafes, to streamline the user experience.

• Service Provider Networks

  •  Internet service providers (ISPs) often deploy Passpoint to allow their subscribers to access their Wi-Fi networks automatically, even when they are away from home.

• Enterprise Networks

  •  Some organizations use Passpoint to provide employees with secure and seamless Wi-Fi access in different office locations.
