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.
