The Study of Interference between UMTS and Wi-Fi in Indoor Environments

Abstract

Nowadays, wireless services are becoming increasingly present in our daily lives. UMTS technology is successfully imp lemented and is already installed everywhere. Wi-Fi service should be tested to coexist with UMTS service, with minimal interference. Hence in typical do mestic environments is verified the possibility of coexistence of two antennas, in the same access space. Initially, the characteristic of Wi-Fi antennas parameters are measured. Then we measured the effect of positioning the two antennas in vicinity, in different configurations. Results of measurements show that the configuration of the access point can determine the pair of antennas that provides better appearance in terms of adaptation and topology of the installation.
