It is provided a method, comprising determining a respective elevation of each of plural beams from an access point based on stored configuration data, wherein each of the plural beams is identified by a respective identification included in an indication comprising the identification of the respective beam and an information on a respective received beam power, and the indication is received from a terminal; selecting a first beam and a second beam among the plural beams such that the elevation of the first beam is different from the elevation of the second beam; retrieving, from the stored configuration data, a transmit power of the first beam and a transmit power of the second beam; estimating an estimated elevation of a line connecting the access point and the terminal based on the received beam powers, the transmit powers, and the elevations.
