Wireless Microphones Interference Decreasing Using LTE Filters

Abstract

Strong signals from mobile phones can disturb and interfere with television signals making the channel impossible to receive the signal. In this paper, we measured the interference between wireless microphones and mobile phones that work in the same frequency Bandwidth from 750MHz to 850MHz. The measurements were performed on Košutnjak site from Radio Television Serbia (RTS) distribution main center. In this paper, we have two main contributions. First, we described the influence of existing Long Term Evolution (LTE) technology on wireless microphones which is used in Television stations. Second, it is described how this influence can be reduced using LTE filters searching for optimal filter response.
