Original Abstract

Recently, the study of coexistence between Long Term Evolution (LTE) and Wireless Fidelity (Wi-Fi) systems in common Industrial, Scientific and Medical (ISM) bands is a hot topic. For such a study, an appropriate measurement setup with reliable evaluation process is essential. In this paper, we present a simple laboratory measurement testbed to measure and evaluate coexistence scenarios of LTE-Downlink (LTE-DL) and Wi-Fi systems in indoor environment. Completely automated measurement of the objective parameters on the physical layer (PHY) level, real-time evaluation of the results and flexibility are the main advantages of the proposed concept. Different coexistence scenarios between LTE-DL and Wi-Fi (using IEEE 802.11n/ac technologies) in the 2.4GHz ISM band were selected to validate our proposed measurement setup in an indoor environment. At the evaluation of the obtained results it was observed, that the LTE-DL system influenced by IEEE 802.11n/ac systems, similarly IEEE 802.11n/ac influenced by LTE-DL, has different performance.
