A new triangular-grid ray tracing (TGRT) method is proposed. It is based on dividing the propagation region into triangles. The number of triangles is decided by the number of vertices of the structures, instead of their dimensions. For the 2D case, it can decreases the visible decision calculation to two edges for each triangle.

Ray Tracing Methods The propagationModel and raytrace functions use a ray tracing model that finds LOS and non-line-of-sight (NLOS) paths. The model finds LOS paths by shooting a ray from the transmitter toward the receiver. If the ray does not interact with a surface before reaching the receiver, then an LOS path exists.

The model was developed to check the propagation quality of the 5G network using 3-D ray tracing technique. The model was implemented using the Matrix Laboratory (MATLAB) software. The results from our performance evaluation showed that our model was able to produce a better 5G propagation quality over a wider bandwidth in lesser time.

The propagation models are classified mainly into two types: 1. Outdoor propagation model. 2. Indoor propagation model. 4.1 Outdoor propagation models In the mobile communication system radio transmission often takes place over discontinuous terrain. The terrain profile may vary from a simple curved earth profile to a highly mountainous profile.
