- Abstract
- We collected channel measurements using smartphones in actual cellular environments. The measurement data contains physical cell identifier (PCI) information, but not the base station (BS) locations. Separately, the BS locations can be obtained from the spectrum information system [1] operated by the government. To match the measured PCIs with the BS locations, we generated a radio environment map (REM) based on the geographic information system (GIS). Utilizing the generated REM as a reference model, we matched the measured PCIs with the corresponding BSs. As the result, the distance between the user equipment (UE) and the BS was obtained, and the distance-dependent channel characterization became available. Finally, this paper presents the distance distribution of path loss and coverage based on the measurements.
