Abstract

By the end of second decade of XXI century different wireless technologies typically coexist in the same geometrical space and share the same unlicensed frequency bands. Although the interference of Wi-Fi and 3G networks is quite well known by the present time, the wireless engineers still lack good estimation methods of such an impact. Here we give a view on the mask of the UMTS 2100 signal, provide practical measurements, propose a model of its attenuation in order to provide the average signal strength level value. Finally this article provides numerical estimation for signal to noise degradation in order to evaluate the interference effect.
