Study of RSSI and Throughput in Identical Residential Units with Various Wi-Fi Configurations

Indoor communication is very popular in residential and office environment for the users with low mobility. Wireless signals are significantly affected by various obstructing materials and surfaces. This paper presents a study measuring the received signal strength indicator (RSSI) and throughput in a typical 3BHK residential unit. The propagation scenarios are line-of-sight (LoS), obstructed LoS (OLoS) and non-line-of-sight (NLoS). The operating frequency band of transmitted wireless signal is sub 6GHz band. We placed some more obstructing material inside the flat and analyzed the receiver performance in terms of RSSI and Throughput. The study observed a relationship between RSSI and throughput across different propagation scenarios and found that, in some cases, the performance under OLoS conditions was superior to that of LoS.
