GSM Baz İstasyonlarının Elektromanyetik Güç Yoğunluğu’nun Lagrange İnterpolasyon Yaklaşımı Kullanılarak Belirlenmesi

Öz

Gezgin haberleşme sistemleri insan hayatında önemli bir rol oynamakta ve bu rolün önemi insan sayısındaki artışla ortantılı olmaktadır. Raporlar, gezgin haberleşme sistemlerinin kullanımına ve nüfus artışına paralel olarak baz istasyonu sayılarının da arttığını göstermektedir. Baz istasyonu gücünün belirlenmesi özellikle kalabalık şehirler için çok önemlidir. Baz istasyonlarının olası tıbbi etkilerinden dolayı insanların baz istasyonlarından ne kadar etkilendiğini bilme hakları vardır. Bu nedenle 120 baz istasyonunun radyasyon seviyesi baz istasyonlarından 20, 40 ve 60 metre mesafelerde 900 MHz frekansında ölçülmüştür. Bu çalışmada, rastgele ara mesafeler için elektromanyetik seviyenin gücünü tahmin etmek için lagrange interpolasyon yöntemi uygulanmış ve her mesafe için 0,99'un üzerinde korelasyon elde edilmiştir.

Determining the Electromagnetic Power Density of GSM Base Stations by Using Lagrange Interpolation Approach

Öz

Mobile communication systems are playing an important role in human life and the importance of this role depends on the increase in the number of people. Reports show that the numbers of base stations are getting increasing in parallel to use of mobile communication systems and population growth. Determining the base station strength is very important especially for the crowded cities. Because of the possible medical effects of base stations, people have the right to know how much is affected by base stations. Therefore, radiation level of 120 base stations have been measured 20, 40 and 60 meters distances from base stations at the frequency of 900 MHz. In this study, the lagrange interpolation method is applied to estimate the strength of electromagnetic level for random intermediate distances and, above 0.99 correlation was achieved for each distance.
