Abstract
Intelligent reflecting surfaces (IRSs) became, during the last few years a major player in beyond 5G networks because it can assist millimeter wave and terahertz transmissions to overcome their propagation and blockage issues. IRSs provide the network with alternative line of sight paths and extend the network coverage. However, deploying a single IRS seems not to be enough, specially in crowded large indoor area with multiple blocking elements. In this paper, we will discuss a scenario of the network with two implemented IRSs and compare it with the case of a single IRS, hence proving the superiority of first case to extend the coverage and reduce the effect of blockage occurrence in the network. Then, we will propose optimal placement of two IRSs in the environment to enhance the overall performance of the network. The proposed method is based on maximizing the average received power over all possible user equipment (UEs) positions within the study area. This method can guarantee larger received power for almost all UE positions. Finally, we study the performance of the network with different blockage probability of occurrence cases that effects on both the direct link between access point and UE and the alternative link between IRS and UE.
