A system and methodology for network planning in which a software based tool provides network engineers with the capability to more precisely plan for traffic loading within the network on a cell site by cell site basis. Thus for each cell site, variations in geographic location, device mix, historical usage patterns and other factors are taken into account to allow for more accurate network planning and for more efficient use of capital. Cell sites with a higher traffic profile based upon historic device mix and usage patterns will be associated with lower OSF values thus enhancing the user experience for a device user in communication with that cell site. On the other hand, for cell sites with a lesser traffic profile, a higher OSF value is ascribed thus allowing for capital to be deployed elsewhere while still maintaining a positive user experience for users relying on that cell site.
