Abstract :
In this paper we present in-lab measurement results of radar interference into 4G LTE mobile communications system at 1800 MHz frequency band. Influence of various radar and LTE system parameters including radar antenna rotation effect on LTE traffic throughput loss due to interference is investigated. Measurements have been carried out using a fully functional Huawei LTE DBS 3900 1800 MHz base station connected to live mobile operator network. Paper includes estimation of radar interference levels and provides description of conditions which make the most impact on LTE network quality.
