Site diversity is the most effective way to recover a signal lost during heavy downpours,
especially in tropical regions since other mitigation techniques such as adaptive power …

With the many folds increase in demand for capacity in mobile broadband communication
technology every year, wireless carriers must be prepared for the tremendous increase in …

The main factor impairing radio wave propagation is atmospheric refraction. To account for
fade margin, a crucial component of a reliable radio link, accurate estimates of the refractivity …

Given the massive rapid growth for capacity in wireless data telecommunications every year,
wireless carriers must be planned for a thousand-fold increase in mobile traffic in 2020. It …

The present work characterizes the degree of rain-induced attenuation on 15-80 GHz earth-
space communication links. Eutelsats 36B and 36C, and NigComSat-1R satellite links over …

In recent years, the higher frequency band is being adopted for radio communication and
satellite link systems due to the congestion at the lower frequency bands. However, at high …

Signal deterioration will result from tropospheric scintillation in microwave communication
connections with small fade margins. In tropical areas, very few scintillation research has …

The incidence of multipath fading in two Nigerian cities is explored in this study utilising the
geoclimatic factor technique and ITUR Recommendation P530-14. Nigerian cities Abuja and …

Domestic satellite signal failure due to rainwater accumulation on the prime focus parabolic
dish surface is a common phenomenon in the tropics. The problem is more pronounced with …

The partial reflections technique has been employed to study the generated or amplified in
