Wideband Indoor Radio Propagation Measurements at 5.4 GHz

Resumen

Wideband indoor time domain measurements at 5.4 GHz are presented in this paper. A swept Time Delay Cross Correlator is used to measure the radio channel, and the measurements are performed using an autonomous robot that follows a predefined route line-of-sight and non-line-of-sight modern office buildings. Analysis shows that the RMS delay spread follows a normal distribution whose mean does not always increase with distance. Also, the global statistics of the RMS delay spread follow a truncated normal distribution with a better fit. Results are presented in the form of RMS delay spread and power delay profiles.
