This paper presents the results of frequency domain channel sounding of wireless in-car channels. Based on an extended measurement campaign different application-specific channels are characterized by channel gain, cumulative density functions and time dispersion parameters. The measurement sets are chosen for the freely disposable industrial, scientific and medical (ISM) frequency bands. Characteristic time-domain values are calculated from ultra-wideband (UWB) channel transfer functions exhibiting a frequency range of 433 MHz-10 GHz. Inside the drivers cabin both line-of-sight (LOS) and obstructed-line-of-sight (OLOS) radio links are considered. All parameters are derived from measurements using omni-directional antennas and can thus be applied to common channel models.     «
