Abstract
Light communications, also denoted as LiFi, is promising for future wireless indoor networks. For performance evaluation, the IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models based on non-sequential ray tracing. In this paper, we validate the modeling approach behind by means of measurements. The same indoor scenarios, where measurements took place in 200 MHz bandwidth, have been modeled in 3D and applying ray tracing. We show that the mean-square error between simulation and measurement is below 2%. Finally, we investigate important channel parameters like path loss and coherence bandwidth as a function of distance with and without line-of-sight.
