Abstract
including an analysis of where additional placement of microwave towers for microwave bearers, mobile cell citing and wireless loop placing across the roads (pipe line gas) needs to take place and which areas the existing digital network is not properly serving the east north of Iran (Tabriz- Uromia) . By answering these questions rapidly and effortlessly, planners can maximize profitability and establish a competitive advantage.

The project will detail to the reader how a GIS radio planning tool enables the planning engineer to model and optimize the performance of the network. Added to this is the inclusion of demographic analysis, roadway networks and the geomorphology of the landscape by using 3-D geospatialdata, Due to the availability of the data and the proximity of the researchers the study site will be the east north of Iran. It should also be noted that with the advent of the deregulation of the telecommunication markets across Iran, there are an increased number of network providers and a greater complexity of networks using a wider range of the frequency spectrum. The performance of the network needs to meet a number of technical criteria such as optimum radio coverage of customer demand areas and interference thresholds, in an increasingly congested spectrum.

The main targets of all radio network planning tools are to aid in the achievement of realizing the required radio coverage, to maximize network capacity and to reach good quality of service and to minimize the cost of network infrastructure (Telstra, 1998). The development of a GIS, requires Geographic Data, Telecommunications related data, general visualization and radio propagation analysis aspects (Ansary, 1998)
