Optimal Antenna Placement in a Distributed Antenna System using RSSI Optimization for Indoor-to-Outdoor Propagation

This paper represents the indoor-to-outdoor propagation characteristics for a distributed antenna system which is providing connection to end users via four access point locations. The access point locations are optimized by analyzing the layout model variants by adding furniture and reinforcing rods with the primary concrete structure using particle swarm optimization. The received signal strength indicator (RSSI) is calculated at various distance from the access points by calculating the path loss at each point on the layout. Optimizing the access point locations helped in reducing the path loss at each grid location, further helping us in achieving optimum RSSI.
