TETRA outdoor large scale received signal prediction model is presented here.
The model follows log-distance model. It is derived based on received signal strength survey measurements of a TETRA
system, operating in the 300-400 MHz band, in Riyadh city.
The model is aimed to assist practicing engineers in the estimation of received power, or electric field strength as well as path-loss
at any given distance from the base station or vice versa. The model exponent (n) for the selected routes is found to be 3 ± 0.7.
However, the overall value of n for urban area in the Riyadh city is found to be 3.22. It is noted that the value of n obtained here is low,
compared to values obtained in several European cities, as the streets are wider and the buildings are lower in most part of the route in Riyadh.
