Nettet22. sep. 2024 · A reconfigurable intelligent surface (RIS) reflects incoming signals in different ways depending on the phase-shift pattern assigned to its elements. The most promising use case is to aid the communication between a base station and a user when the user has a line-of-sight (LOS) channel to the RIS but the direct channel is blocked. NettetAssume the path loss exponent for in-building line of sight to be 2.7. First, let's compute the path loss at 4 meters for the carrier frequency of 3960 MHz using the relations in (4.1) and (4.2): (4.3) For the complete range of 1 to 10 meters, the path loss is shown in Figure 4.6.
