With the commercial use of 5 G network

operators pay more and more attention to the investment cost of 5 G network deployment. In the initial stage of 5 G network construction

the operator will simulate the designated area through the network planning tool

and finally formulate an effective network construction scheme according to the simulation results. Ray tracing algorithm is often used as a fi ne simulation method because it can well model the path of direct

refl ection

diffraction and transmission of signal. This paper introduces the research progress and algorithm application scenarios of ray tracing

studies two ray tracing algorithms through actual cases

analyzes and compares the application differences of the two ray tracing algorithms in 5 G planning simulation

verifi es the reliability of the two algorithms

and provides a variety of support schemes for the future 5 G planning network construction.
