INVESTIGATION OF INDOOR WI-FI STABILITY BASED ON THE RECEIVED SIGNAL STRENGTH INDICATOR (RSSI): A CASE STUDY AT UC TATI HOSTEL

Abstract

Wi-Fi has become indispensable in today’s digital era, enabling connectivity in homes, workplaces, and educational institutions. However, ensuring stable indoor Wi-Fi remains a challenge due to factors such as structural obstacles, interference, and varying user loads, all of which impact signal strength. This study examines indoor Wi-Fi stability at UC TATI Hostel, aiming to achieve an optimal RSSI value of -67 dBm using Ekahau AI Pro and the WiFiman app for analysis. Various scenarios were assessed, including different AP types, placements, and user loads. Findings revealed that wall-mounted APs outperformed ceiling-mounted ones, and modern APs with advanced features were more effective than older models, particularly under heavy user loads. Additionally, environmental factors like interference from lighting influenced performance. The study offers practical recommendations for enhancing Wi-Fi in similar indoor settings, emphasizing the importance of upgrading to modern APs, strategic AP placement, and reducing interference.
