A mobile station for use in a Radio Access Network, RAN, connected to a core network in which there is one or more Public Land Mobile Networks, PLMNs. The system includes a map server including a processor and a memory storing instructions executable by the processor to make the map server operable to prepare a basic route from a route origin to a route destination and obtain information regarding characteristics of the wireless communications network along the basic route. The organic light emitting device can reduce the angle dependency of the emission brightness and the emission color by outputting the light emitted from the emission layers in a condition where the light is scattered by the light scattering means.
