Abstract

The signal strength in 5G mobile communication systems is signifcantly infuenced by the surroundings, with key factors including the path diference, operating frequency, and obstructions at specifc locations. Consequently, planning a communication system that can deliver improved signal strength becomes highly challenging. To address this issue, indoor path loss models are employed to estimate signal loss in diferent environments, frequencies, and distances. This paper introduces an intelligent multi-objective genetic algorithm aimed at enhancing path loss and received signal power. A comparative analysis is conducted to evaluate the performance of the proposed intelligent optimization algorithm against the traditional approach. The path loss and received power of various scenarios are estimated using various path loss models. The 5GCM indoor ofcce, 5GCM InH shopping mall, 3GPP TR 38.91 InH ofce, mmMAGIC InH ofce, METIS InH shopping mall, and IEEE 802.11 ad InH ofce indoor path loss models estimates the path loss of 62.37 dB, 62.15 dB, 63.12 dB, 50 dB, 55.18 dB, and 52.89 dB in traditional approach and 36. 87 dB, 35.86 dB, 36.84 dB, 68.80 dB, 36.23 dB and 33.94 dB using GA approach and received powers of −12.17 dBm,−11.37 dBm,−12.17 dBm,−5.80 dBm, −12.24 dBm and −8.68 dBm in traditional approach and 26.13 dBm, 27.14 dBm, 26.15 dBm, −5.80 dBm, 26.75 dBm and 29.05 dBm using GA approach repectively. The 5GCM and 3GPP models produces the path loss diference above 25 dB and mmMAGIC, METIS and IEEE models produces a path loss below 19 dB. Except mmMAGIC model, all models produces the recceiver power diference above 37 dBm. Therefore, the highest path loss diference of 26 dB is observed in 5GCM InH shopping mall model and the highest reccieved power difference of 39.01 dBm is observed in METIS InH shopping mall model. The results clearly demonstrate that the proposed intelligent optimization approach outperforms the traditional approach across various indoor scenarios.
