                            <p>Üniversiteyerleşkelerinde kablosuz ağlar son yıllarda büyük önem kazanmıştır. Bu ağlarınüniversite yerleşkeleri gibi büyük bölgelerde planlanması, tasarlanması vekurulması sırasında birçok problemle karşı karşıya kalınmaktadır. Buproblemlerden bazıları, yerleşkelerin fiziki özellikleri, uygun cihazkonfigürasyonu ve gerekli olan cihazların adedinin belirlenmesidir. Özelfirmalar proje için kendi yöntemleri ile marka, model, maliyet ve adetbelirlemektedirler. Ancak çıkan sonuç her zaman kurum açısından pekte uygunolmamaktadır. Bu nedenle yerleşkelere uygun sinyal dağılımına sahip planlama vetasarımın yapılabilmesi birçok sorunu çözmekle birlikte kullanımı vememnuniyeti artırıcı etkiye sahip olacağı düşünülmektedir. Bu çalışmada, HititÜniversitesi Kuzey Yerleşkesinde kurulu olan bir adet dış ortam erişimnoktasından (Access Point-AP) elde edilen sinyal dağılımına göre coğrafi bilgisistemleri görünürlük analizi yardımıyla tüm alan için kestirim yapılarak uygunsinyal dağılımı belirlenmeye çalışılmıştır. Çalışma sonunda 56 hektarlık birbölgeye toplam 9 adet dış ortam AP ile uygun sinyal dağılımı elde edilmiştir.</p></trans-abstract>

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.</p></abstract>
