Wideband Directional Radio Propagation Channel Analysis Inside an Arched Tunnel

Analysis of DSRC Service Over-Reach inside an Arched Tunnel

“…The analysis of the channel for large coverage communication systems was provided in [23], [24], whereas for the inspection of the over-reach in the DSRC out-of-zone, it is essential to analyze the propagation channel for the nearby area in this particular scenario. For this purpose, two specific scenarios with transmitter (Tx) locations according to the RSU position in Japanese DSRC standard were investigated.…”

Channel modeling and measurements in waveguide-like structures

“…In [60] and [61], the path loss exponent n that indicates the increase rate of the path loss PL with respect to the distance d was found to be less than 2 based on wideband channel measurements at different frequency in different types of tunnels. The same observation was made based on measurements along LOS corridors in different frequency band range from 450 MHz to 90 GHz [40], [62]- [69].…”

Channel Measurement and Modeling in Complex Environments

“…For instance, a hybrid tunnel propagation model has proposed based on the measurements at 900 MHz on horizontal and vertical polarization in a typical coal mine [88]; the radio propagation model for underground low-power sensor nodes [89]; the measurements in road tunnel [90], railway tunnel [91], subway tunnel [92], etc. There are also few propagation characterizations based on wideband radio channel measurements, which have been made in a highway road tunnel at 5.2 GHz [90]; in the underground mining environments in the range of 150-900 MHz [93], at 1 GHz [94], and at 2-5 GHz [95,96].…”
