OPTIMIZATION OF TIZETI WI-FI COVERAGE IN AN ACADEMIC BUILDING

This study addressed the internal performance deficits of the Tizeti wireless network within the multi-room FUPRE Physics Department, a challenging environment characterized by a single band 2.4 GHz infrastructure and high signal attenuation from thick concrete walls. The aim was to transition the network from an uncoordinated installation to an optimized, high performance system capable of sustaining academic traffic. A quantitative, applied engineering methodology was employed, utilizing a comparative "Before and after" analysis. Optimization involved: physics-informed AP repositioning to mitigate 10 dB wall loss; rigorous Channel Planning (1, 6, 11 rotation) to overcome spectral congestion; and implementation of Quality of Service (QoS) policies on the MikroTik Router to prioritize Data Packets. Post optimization results demonstrated substantial improvements: a 64.4% increase in average Throughput and a 36.8% reduction in Latency, achieving a stable RSSI of ≥ -67dBm across 97% of the critical area. The project successfully proved that meticulous RF engineering and logical configuration can overcome severe physical and hardware constraints, delivering stable Roaming and high capacity necessary for modern academic operation.
