This research involves comparative analysis of mobile radio transmission path loss models in Lagos state. Lagos, coastal region within an altitude of 38m, and geographical coordinates (63.60N, 3.280E), in the rainforest area of south-western, Nigeria. The measured active base stations propagation measured parameters (for selected areas; Agbowa, Ibeju Imota, Ilupeju, and Surulere in Lagos between 2019 and 2020 from MTN-NG Microsites) recorded between frequency range of 1500- 2500MHz band with a visible line of sight (LOS) in three areas within the state. Stanford University Interim, ECC-33 and COST 231 models were adopted and optimized models were developed and their empirical outcomes revealed standard deviations (SDs) of 1.87, 1.11, and 31.78 respectively at 500m distance from the microsite of average rural areas. For the sub-urban areas, RMSEs (root mean square errors) observed were 39.11, 0.04, and 1.98 and with SD being 33.52, 0.03, and 1.69.  More so, for an urban area, it was discovered that the RMSEs obtained for these three models were 34.84, 1.98 and 0.55 with SD of 29.86, 10.27 and 0.47 at same distance of 500m. The implication is that probability of an improved performance is high when optimized models is adopted compared with what is in existence.
