 The use of reconfigurable intelligent surfaces, RISs, or intelligent reflecting surfaces, IRSs, can be used to improve the efficiency of wireless communication systems by altering the way signals travel through them. These surfaces can be used to create a more efficient wireless environment, allowing for improved data transfer rates and reduced power consumption. Additionally, they can be used to create a more secure network, as they can block certain frequencies from entering or exiting the network. The technology has been shown to be effective in improving the performance of existing networks, and it could also be used to create new networks in the future.
