DATED: Vijay Kumar Chaurasia ii ABSTRACT Mobile cellular communication has already entered the mass market, and mobile internet services will soon become a reality. The frequent use of mobile radio technologies for people are has a direct impact on the deployment of base stations or radio access points, including antennas. To serve an increasing number of users, it requires an increasing number of base stations. Thus, operators must. carefully plan the deployment and configurations of radio base stations in order to support at a level of quality expected by customers. Planning is used to help radio engineers in their difficult tasks of balancing requirements or radio coverage and quality with customer's satisfaction and other practical aspects. These planning make extensive uses of functionalities very similar to a Geographical Information System (GIS) or even to base their product on a GIS. Furthermore, because radio communication between base stations and users is crucial, all computations are based on the use of radio-propagation predictions. Until recently, empirical propagation prediction seemed sufficient. However, more efficient planning and the planning of nonvoice services or of a mixture of voice and nonvoice services require more accurate propagation-prediction models. These propagation models are usually based on the computation of the physical interaction of radio waves and the environment. The establishment of tower cannot be performed efficiently manually because of their complexity and because of the time pressure involved in deploying costly infrastructure. Thus, there is a need of classification of area type and planning by radio engineers to design, analyses, and compare various scenarios. Thus, more detailed information is required, especially in urban environments where most users are located. If we are going to establish the towers, there should be need of consideration of road networks, railway lines and settlements of whole area planning in land use area. The aim is to develop some relationship between radio- propagation models used for mobile radio network planning and find the existed coverage and establish the new wireless tower where coverage are very less (or no coverage). The actual position of wireless towers can be identifying after ground survey only. The simulation results show the use of conventional propagation models and rough geographical databases for the planning of future cellular systems.
