In any kind of network planning it is the central task to estimate and thus analyze propagation characteristics of a radio system through a medium in order to state accuracy in signal parameters for efficient network planning. The system must necessarily incorporate in itself the ability to predict the accurateness of radio propagation behavior. The site measurements each and every time are no doubt expensive & costly, so these models are a better alternative to that and even a lot less costly along with better suitability. Path loss thus is now a major consideration while laying down any network of base stations that can be used to estimate transmission requirements for a particular region thus offering better Quality of Service.
