60 GHz in-cabin real-time channel sounding

Ultrawideband Channel Sounding within an Airbus 319

“…From these results it is verified that CH 3 and 4 depicted higher delay-spread (and deviations) due to the lower IDR and MIDR. For CH1 and CH2 (mainly under LOS condition and then higher IDR and MIDR), the median rms τ ranges from 8.84 to 21.53 ns, which are lower than results reported at 2 GHz within an Airbus 319 [7] (i.e., there between 29.2 and 58.2 ns), higher than the results reported at the 60 GHz band within an Airbus 340 [8] (i.e., between ~2 and 6 ns), and in the same range than the results reported for a similar UWB band in a Airbus 319 [3] and within a Boeing 737-200 [4] (i.e., between ~10 and 30 ns, and between ~8 and 21 ns, respectively). Moreover, it is verified that the Airbus 319 incabin channel has median 0.9…”

“…Note that the Airbus 340 considered in [8] has larger crosssection than the Airbus 319 but not larger delay spread was perceived. Besides, note that the results presented in [3] and [4] were performed with a VNA, which implies a tradeoff between resolution and time consumption for performing measurements.…”

Characterization of 60 GHz shadowing by human bodies and simple phantoms

“…Real-time multi-antenna channel sounders at 60 GHz are rare but do exist. Such a channel sounder was presented in [5] and has since been used to characterize the shadowing events due to human bodies using two access points and one Tx [3]. Some measurements do require a larger number of antennas, which can exclude the possibility of using real-time measurements.…”

W-band photonic-wireless link with a Schottky diode envelope detector and bend insensitive fiber

“…• characterization of the wireless channel: most efforts for channel characterization and modelling have regarded frequencies in and below V-band or only estimated path loss [13,14]. A characterization of the W-band wireless channel has been performed [15] and is presented in section 2.…”
