This paper investigated the suitability of some popular terrestrial rain attenuation prediction models for Lagos Island, Lagos, Nigeria, at 17 and 45 GHz. At 10 GHz and above, line of sight radio communications is impeded due to the fact that larger raindrops, and is therefore follows that, to effectively model a terrestrial link system in tropical stations, it is necessary to carefully investigate and identify the most suitable model to efficiently and accurately predict rain attenuation exceedances at various percentages of time. Monthly rain data spanning five years (January 2014 to December 2018) were sourced from the Nigerian Meteorological Agency. Four prediction models (ITU-R P.530-17, Da Silva Mello, Crane Global and Moupfouma) were studied. ITU-R P.530-17 model produced the closest predicted values when compared to the measured attenuation values at both 17 and 45 GHz, and it was distantly followed by the Crane Global model. However, at 17 GHz, Moupfouma exhibited the worst performance, while Da Silver Mello showed the worst at 45 GHz, for all percentages of time exceeded. Furthermore, this outcome surmises that the ITU-R P.530-17 model adequately cater for all locations for terrestrial communication links, for temperate, tropical and equatorial alike, for domestic (at p=0.1%) and commercial users (at p=0.01%) of the time exceeded.
