The measurement setup was identical as in the case of measurements of UWB in-vehicle channel in frequency domain performed on 17 Oct and 7 Nov 2013. The RX antenna and TX antennas were placed according to <a href=\"#fig1\">Figure 1<\/a>. The receiving antenna was placed at 10\u00d710 spatial points using the polystyrene rack which ensured defined location of the antenna. The polystyrene rack utilizes a 3 cm grid distance between neighboring measurement locations.
