Capacity Maximization of the mmWave Networks Deploying Intelligent Reflecting Surfaces: An Enhancement Approach for 6G Internet of Things

An intelligent reflecting surface (IRS) is a reconfigurable mechanism that may be used to regulate the transmission of radio signals by modifying the electrical and magnetic characteristics. As a result, IRS is regarded as an advanced technology for sixth-generation (6G) Internet of Things (IoT) communications infrastructure. The objective of the work is to improve the capacity of the micro cell, i.e., enabling the micro cell base station of a two-tier network to serve an increased number of devices. Therefore, the work deployed an IRS in a micro cell and achieved significant improvements in the performance with a reduced transmit power of the micro base station.
