TETRA Outdoor Large-Scale Received Signal Prediction Model in Riyadh City-Saudi Arabia

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, Saudi Arabia. This 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 value of the model exponent (n) for the selected routes is found to be 3 plusmn 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 routes in Riyadh.
