Real-world connectivity

The Vianden Castle area and Our valley have solid signal. The Ardennes forest sections near Clerf and Wiltz have 4G on main roads and in village centers but signal weakens in deep forested areas between towns. The German and French border crossings all have coverage on the Luxembourg side.
