Abstract
This document discloses a solution for determining distances. In the solution, a first frame is transmitted (200) to a second apparatus; a second frame is received (202) from the second apparatus, as response to the first frame; an indication of the duration between the reception time of the first frame and transmission of the second frame is received (204); an indication whether the duration is constant or variable is received (206); and in case the duration is constant, the distance between the first apparatus and the second apparatus is determined (208) based at least partly on the indication of the duration.
