Abstract:
As the LTE is deployed commercially, the effect of interference of LTE mobile phone is issued. The paper presents an interference analysis of LTE mobile phone in the sound systems. Three LTE mobile phones from different manufacturer’s brands are used for measuring interference and three GSM phones are tested for the relative comparison with the LTE phones. A speaker and a wire telephone are applied as sound systems which are affected by LTE phone. The output spectra exposed to the LTE phones are presented and the interfered noise levels in sound systems are experimented at various distances from the LTE phones, and also at various powers of the LTE phones. The experimental results show that LTE mobile phones generate an interfered noise in sound systems up to the distance of 30~40cm. Also, the interfered noise is generated at over the power of 0dBm.
