In a method and a device for generation of path profiles for use in radio wave propagation planning, several path profiles adjacent to a generated first, primary path (501 ) are generated (503).Obstacles detected in the adjacent path profiles are then transformed and translated (505) onto the primary path profile, whereby a resulting path profile taking into account both obstacles present in the primary path profile and obstacles close to it. The method and the device are particularly useful in urban and suburban areas where obstacles tend to be of a discrete nature and can be used for many types of, applications such as point-to-point point-to-multipoint and area coverage, applications.
