This study examines the relationship betweenatmospheric factors [temperature and relative humidity] and network performance [call drop and Radio Resource Control] in Lokoja Metropolis. Monthly data collected from Globacom[GLO] office in Lokoja and Nigerian Meteorological Agency [NIMET] office in Lokoja over a one-year period reveals significant correlations between atmospheric variables [Temperature and relative humidity] and network performance [Call drop and Radio Resource Control]. We observed that call drop is directly proportional to temperature and relative humidity, while Radio Resource Control [RRC] has an inverse proportionality with temperature and relative humidity, assuming other meteorological variables are kept constant. Statistically, call drop showed a positive correlation of 0.35493 with temperature and 0.63769 with relative humidity, while RRC showed a positive correlation of 0.37289 with temperature and 0.5756 with relative humidity. Taken together, these findings indicated that increased temperature and humidity increased call drops and lower Radio Resource Control [RRC] success rates. This research has provided insights useful to the telecom operators and regulatory bodies to ensure network reliability, better resource allocation, environmental consideration and quality of service in tropical regions similar to Lokoja. Additionally, this research can also be useful in identifying key performance indicators, developing mitigation strategies, improving network maintenance and enhancing customer experience. Correlations were measured using Pearson correlation coefficients at a 5% significance level. These findings imply that network operators must account for atmospheric variability in optimizing reliability, resource allocation, and planning for mobile services in tropical climates. Despite being weak, this correlation is statistically significant and meaningful in real-world scenarios where multiple environmental and operational factors collectively influence call drops.
