Okumura-hata model tuning for TETRA mobile radio networks in Saudi Arabia

Network designers rely heavily on path-loss models to predict outdoor radio coverage areas within a certain error using conventional propagation models designed for systems prior to 4G. This paper provides Radio Frequency (RF) engineers and regulators with a reference that presents results of tuning the Okumura-Hata model to increase its accuracy to be used for TErrestrial Trunked RAdio (TETRA) mobile radio applications in Saudi Arabia. It includes correction factors based on measurement campaigns conducted in eight small-medium cities in Saudi Arabia. The selected cities covered all clutter classes that can be found in the country.
