# UniHGW

**UniHGW** is an open, free Wi-Fi network provided by the [[universitatsrechenzentrum-urz]] at the [[universitat-greifswald]]. It serves as a limited alternative to the secure [[eduroam]] network.

## Purpose
UniHGW is intended for:
1. **Short-term guests**: Providing quick and easy internet access.
2. **Bootstrapping**: Allowing users to configure [[eduroam]] on devices that lack a wired network connection and cannot use mobile data.

## Technical Constraints
The network is subject to several restrictions compared to the standard campus infrastructure:
- **Infrastructure**: It utilizes a separate DSL connection rather than the DFN X-WIN science network.
- **Access Control**: Users must authenticate through a [[captive-portal]] as a guest.
- **Performance**: Bandwidth and concurrent user capacity are limited.
- **Connectivity**: It provides external internet access only. Internal university resources and licensed academic publications remain inaccessible unless the user employs a [[vpn]] or authenticates via [[shibboleth]].

## Usage Guidelines
- **Preference**: [[eduroam]] is the recommended connection method for all university members.
- **Events**: For organized conferences, dedicated conference access (**Tagungszugänge**) is preferred over UniHGW.
