Residential indoor measurements of the line of sight (LOS) and non-LOS (NLOS) distance dependent path loss are analysed from 10 MHz to 4.5 GHz. For these measurements, a time domain sounder is used to interrogate the propagation channel in two ways: static, and dynamic. For the static measurements, the transmit and receive antennas are located at predefined locations and the sounding premises vacated before capturing channel impulse responses (CIRs). For the dynamic measurements, a person displaces the receive antenna over predefined paths while the sounder stores CIRs at specific time intervals. The measurements are compared and analysed, and a modelling scheme is proposed for the continuous simulation of the distance dependent path loss.
