* * * A Radio Propagation Model, also known as the Radio Wave Propagation Model or the Radio Frequency Propagation Model, is an empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency, distance and other conditions.

A single model is usually developed to predict the behavior of propagation for all similar links under similar constraints. Created with the goal of formalizing the way radio waves are propagated from one place to another, such models typically predict the path loss along a link or the effective coverage area of a transmitter.

* * * For the RF PLANNING & DESIGN of mobile radio systems, radio wave propagation models are necessary to determine the propagation characteristics. The path loss predictions are required for the coverage planning, the determination of multipath effects as well as for interference and cell calculations, which are the basis for the high-level network planning process.

* * * Generally this planning process includes the prediction of the received power in order to determine the parameter sets of the base transceiver stations ( or access points) . With the introduction of wireless broadband services in third generation systems ( UMTS) or in Wireless Local Area Networks ( W-LAN) , the wideband properties ( e.g. delay spread, angular spread and impulse response) of the mobile radio channel become more and more important for the planning process.

T he environments where these systems ( GSM, CDMA, WIMAX) are intended to be DESIGN & INSTALLED, are ranging from large rural areas, urban, sub urban, high dense urban, dense high rise building ( macrocells) down to indoor environments ( picocells) . Hence wave propagation prediction methods are required covering the whole range of macro-, micro- and pico-cells including in-building scenarios and situations in special environments like tunnels or along highways - tol road
