A method of determining the optimum radio planning parameter of an antenna azimuth heading, comprising receiving, by a control system, a first set of data indicative of network performance for mobile devices of users within a specified geographical area covered by an antenna sector having a first azimuth heading; determining, by the control system, a first set of average values of parameters indicative of network performance based on the first set of data; receiving, by the control system, a second set of data indicative of network performance for mobile users within the specified geographical covered by an antenna having a second azimuth heading, wherein the second azimuth heading is different from the first azimuth heading, determining, by the control system, a second set of average values of parameters indicative of network performance for the antenna sector having the second azimuth value based on the second set of data; comparing the first and second sets of average values of parameters indicative of network performance at the first and second azimuth headings for the antenna sector to determine the azimuth heading at which the network performance is optimized.
