Check out SeeSignal, a great tool developed by the BadVR team that allows users to visualize wireless signal data as interactive holograms overlaid onto real-world environments. The app enables users to explore their local environment and quickly discover hotspots and dead zones, making it easy to optimize their wireless signal experience.
Utilizing data spatialization and sampling algorithms, SeeSignal quickly discovers wireless networks and allows users to select one or more to visualize holographically. The app's features include accessibility support for colorblind users, equipment locating gadgets, and a "WiFi hands" option.
