Abstract: The influence of variable troposphere air temperature, relative humidity and atmospheric moisture on UHF radio network propagation in the tropical region of south western Nigeria has been comprehensively investigated using experimental, theoretical and statistical approaches. This was done by measuring UHF received signal strength (RSS) over the available frequency band of 900-960MHz and specifically at individual service providers operating frequency concurrently with the variable weather parameters. Data were evaluated using modified models and statistical methods. The results show significant influences of the three atmospheric parameters on UHF networks links within the region. Further evaluations reveal that relations between variations in air temperature (control factor) and the received signal strength (RSS) can be technically and instrumentally utilized for efficient link control in the region.
