As most of the main frequency resource of LTE is being used and the propagation model adjustment is amount of work

it is difficult to make an adjustment for every city or scene. A propagation model mapping method based on vector distance which is depended on the landform for non-adjustment city or scene is pushed out. Through the ANPOP simulation analysis of two-dimensional without weighting

two-dimensional with weighting

multi-dimensional with weighting

the performance of multidimensional with weighting is most reliable. It is a significant way for making a network fine planning. Constructions can be guided by it as well.
