Abstract :
With the widespread use of WIFI networks, access location optimization is needed to improve network performance in the buildings. Wave propagation inside the building is one of the most challenging issues in network design and optimal location. Different parts of the building have different effects on the propagation of waves inside the building, such as fading, scattering and propagation of waves in several directions. Due to the nature of electromagnetic waves, the metal parts of the building have a great effect on the propagation of waves. In this paper, the effect of different metal parts of the building, including beams and door and window frames in standard dimensions, on the propagation of WIFI waves using Ray Tracing algorithm and CST software is modeled, and propagation patterns for different angles and distances are obtained. With the using of CST software, various modes such as rooms with different dimensions can be modeled. Then, based on the results, calculate the best location for the receiver. The results show that this method provides better capabilities than statistical methods to determine the best location of the receiver in the building.
