The present disclosure relates to a method of planning a route (R) to a destination (14). A map database (9) defines a road network; and a communications network database (10) defines one or more network parameter for a wireless communication network. The method uses a routing algorithm to plan a route (R) to the destination (14) using the communications network database (10) to estimate connectivity to the wireless communication network along one or more routes generated using the map database (9). The present disclosure also relates to a route planning apparatus (1).
