# Open Wi-Fi

**Open Wi-Fi** refers to wireless network configurations designed to provide low-barrier internet access to users, typically short-term guests or users who are not yet authenticated on a more secure institutional network.

At the Universität Greifswald, this is implemented via the [[unihgw]] network.

## Characteristics
- **Low Barrier to Entry**: Designed for "unhindered" access for guests.
- **Limited Scope**: Often restricted to external internet traffic, excluding internal institutional resources.
- **Authentication**: Frequently employs a [[captive-portal]] to manage guest registration and terms of service.
- **Resource Constraints**: Typically operates with lower bandwidth and lower priority than secure, authenticated networks like [[eduroam]].
