For appropriate regulation and quality assurance, continuous monitoring of cellular network
services is necessary. A drive test measurement was carried out in Calabar, to investigate …

The dependency of mobile network operators on the troposphere for signal transmission
without pre-evaluation and characterization of the region where the signals are transmitted …

Using propagation models helps with communication system planning and maximizes the
use of the radio spectrum, a limited natural resource. Here is a comparative analysis …

The objectives of this study are to understudy the effects of temperature and relative humidity
