In some circumstances (military operation, but also cultural event like a music festival), one may need to have a WiFi network that's quickly and easily deployed, and the same time secured and easy to monitor.
Study the feasibility and security of a deployable WiFi mesh.
Hardware
The wifi mesh will consist of wifi mesh antennas (for example https://www.tp-link.com/en/omada-mesh/product-list/) plugged on solar cells and batteries. This will allow to deploy the network antennas without any cabling.
Monitoring and security software
Next to the hardware, the network will require some monitoring and configuration interface. The goal is to define requirements, find candidates and if needed develop custom management software.
To start this project you should have some knowledge of network management.
