Empirical measurement for path loss characteristics at multiple frequency bands from 2.2 to 14.6 GHz in chamber room
Free space path loss (FSPL) is the loss of electromagnetic signal strength.
This loss is caused by the line-of-sight path through free space. Even in a
line of sight (LoS) indoor single layer, as the distance increases, the path loss in the 1 GHz…
