Disaster scenarios can disconnect entire cities from the core network (CN), isolating base stations (BSs) and disrupting the Internet connection of app services for many users. Such a disruption is particularly disastrous when it affects critical app services such as communication, information, and navigation. Deploying local app servers at the network edge can solve this issue but leaves mobile network operators (MNOs) faced with design decisions regarding the criticality of traffic flows, the BS topology, and the app server deployment. We present the Crisis and Resilience Evaluation Tool (CARET) for crisis-mode radio access networks RANs, enabling MNOs to make informed decisions about a city's RAN configuration based on real-world data of the NetMob23 dataset.
