# Wireless Projector Usage

Wireless projector usage refers to the method of transmitting visual content from a source device (laptop, tablet, smartphone) to a projector without a physical cable connection.

At Universität Greifswald, this is primarily facilitated through the use of [[airserver]]. Because wireless mirroring can create significant interference with existing campus WLAN (such as [[eduroam]]), the [[universitatsrechenzentrum-urz]] enforces strict technical boundaries:

1. **Frequency Isolation**: By banning the 2.4 GHz band and restricting the 5 GHz band to a specific channel (Channel 165), the university minimizes signal overlap and congestion.
2. **Managed Addressing**: The requirement for IP address reservations ensures that these devices are known and manageable within the network infrastructure.

This approach allows for the flexibility of wireless presentations while maintaining the stability of the broader [[campus-it]] environment.
