Abstract:

This letter investigates propagation at 7 and 13 GHz in urban locations motivated by coexistence studies in the recently opened 6 GHz band (5925-7125 MHz) and in the similar 13 GHz band (12700-13250 MHz). Path loss measurements were collected in four urban areas in both line-of-sight (LOS) and non-LOS (NLOS) conditions. We derive floating-intercept (FI) and close-in free space reference distance (CI) path loss models and achieve RMS errors between 5.6 and 9.0 dB. We investigate the applicability of WINNER II and 3GPP models at these frequencies and find that the LOS case provides a conservative estimate of propagation loss.
