 Üniversite yerleşkelerinde kablosuz ağlar son yıllarda büyük önem kazanmıştır. Bu ağların üniversite yerleşkeleri gibi büyük bölgelerde planlanması, tasarlanması ve kurulması sırasında birçok problemle karşı karşıya kalınmaktadır. Bu problemlerden bazıları, yerleşkelerin fiziki özellikleri, uygun cihaz konfigürasyonu ve gerekli olan cihazların adedinin belirlenmesidir. Özel firmalar proje için kendi yöntemleri ile marka, model, maliyet ve adet belirlemektedirler. Ancak çıkan sonuç her zaman kurum açısından pekte uygun olmamaktadır. Bu nedenle yerleşkelere uygun sinyal dağılımına sahip planlama ve tasarımın yapılabilmesi birçok sorunu çözmekle birlikte kullanımı ve memnuniyeti artırıcı etkiye sahip olacağı düşünülmektedir. Bu çalışmada, Hitit Üniversitesi Kuzey Yerleşkesinde kurulu olan bir adet dış ortam erişim noktasından (Access Point-AP) elde edilen sinyal dağılımına göre coğrafi bilgi sistemleri görünürlük analizi yardımıyla tüm alan için kestirim yapılarak uygun sinyal dağılımı belirlenmeye çalışılmıştır. Çalışma sonunda 56 hektarlık bir bölgeye toplam 9 adet dış ortam AP ile uygun sinyal dağılımı elde edilmiştir.

Wireless networks on university campuses has gained importance in recent years. These networks in major areas such as university campuses, are faced with many problems during the planning, design and establishment. These problems are among the first that comes to mind, the physical properties of the campus and is selected according to the characteristics of network equipment. There is no doubt at all points of a wireless network set up in order to provide uninterrupted 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 to have acceptable signal distribution will have the appropriate use of and satisfaction with increasing effect. In this study, due to the start of construction on the North Campus of Hitit University, wireless signal spread using the current spread has been determined with the help of geographic information systems visibility analysis. An area of 56 hectares, with the total of 9 AP the acceptable signal distribution was obtained.
