Experimental Indoor Coverage of a Commercial mm-Wave 5G Network

This paper presents the coverage measurements and path loss results of a 5G indoor signal within the 5G Experimental Center for New Generation Services (5G Laboratory) located in the Department of Electrical Engineering of the University of Chile. An Ericsson AIR 5121 antenna and commercial base station that is in a fixed position inside the laboratory and a 5G router equipment (5G NR mmWave Mobile Hotspot) are used to perform measurements in the 28 GHz frequency band. Both Line of Sight (LoS) indoor and Non-Line of Sight (NLoS) scenarios were considered within the laboratory and in a hall next to the it. The measurement results show acceptable data rates in DL and UL, however a deviation of more than 40dB with respect to the 3GPP TR 38.901 model both in LoS and NLoS conditions was observed. These results are expected to be important to review the coverage behavior of a commercial 5G network at the n261 band millimeter wave frequency.
