Analysis of Interference Patterns and its Environmental Factors on Cellular network

Nduka Watson Aguiyi, Smiles C. Obiajunwa

Abstract


The study looks at ways of mitigating interference in cellular networks using Frequency Hopping Spread Spectrum (FHSS) model. It is true that interference causes huge challenges to cellular networks operating across various frequency bands, including 800 MHz, 900 MHz, 1800 MHz, and 2100 MHz. This study intends to analyse the potency of FHSS in ameliorating interference and its environmental impacts and thus enhance network efficiency. The analysis centres on Cellular 1 and Cellular 2 at Dr. Peter Odili Road and NTA Road, Port-Harcourt, highlighting the spatial heterogeneity of interference patterns. From the analysis, interference hotspots are identified and its environmental factors highlighted. FHSS disperses the transmitted signal, reducing the impact coming from outside disturbances and optimizing spectral efficiency. The results gotten shows great improvements in interference mitigation efficiency when using FHSS, with interference levels reduced from 50% to 5%, 4%, and 6% at different intervals. The research study shows the efficacy of FHSS in improving network resilience and reliability, ensuring seamless connectivity and optimal service quality for users. In essence, the study underscores the critical role of FHSS in mitigating interference patterns in cellular networks. These findings gotten from this study add to the body of knowledge in interference mitigation techniques, informing future efforts to optimize network performance and address the evolving challenges faced by cellular networks.
