Thesenetworks in major areas such as university campuses, are faced with manyproblems during the planning, design and establishment. These problems areamong the first that comes to mind, the physical properties of the campus andis selected according to the characteristics of network equipment. There is nodoubt at all points of a wireless network set up in order to provideuninterrupted service and quality of the signal is expected to be good.However, it should be understood literally cannot meet these expectations.Therefore, to solve many problems to campus planning and design can be made tohave acceptable signal distribution will have the appropriate use of andsatisfaction with increasing effect. In this study, due to the start ofconstruction on the North Campus of Hitit University, wireless signal spreadusing the current spread has been determined with the help of geographicinformation systems visibility analysis. An area of 56 hectares, with the totalof 9 AP the acceptable signal distribution was obtained. CR - Goodchild, M.
