Experimental Coverage Measurements on a Commercial 5G Network in the 28 GHz mm-Wave Band

This paper presents the coverage measurements and path loss results of a 5G indoor and outdoor signal within the 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 and Line of Sight (LoS) outdoor the laboratory. The measurement results show acceptable data rates in DL and UL, however a deviation of 20 dB to 30 dB with respect to the 3GPP TR 38.901, METIS and NYU model. These results are expected to be important to review the coverage behavior of a commercial 5G network at the 28 GHz band millimeter wave frequency.
