Terahertz (THz) Kiosk application offers ultrahigh downloads of digital information to users’ handheld devices. System configuration and multiple paths between the transmitter and receiver have important impact on the achievable data rates. In this paper, the propagation channel of THz Kiosk downloading application is investigated and a stochastic channel model is proposed. Based on channel measurements...
In reality, the dominant components (the specular rays with larger power) of wireless channels should be contiguous and smoothly changing over positions. However, such spatial consistency cannot be guaranteed if the channel is modeled in a purely stochastic way. In this paper, through two series of simulations, we study the spatial consistency of dominant components between ray-tracing and stochastic...
Due to the extra loss resulting from tunnel curve, most of the theoretical models cannot be directly used for propagation inside curved tunnels. In this paper,extensive simulations are made for propagation at different frequencies in different types of curved tunnels, by using a ray-tracing simulator that is validated by numerous measurements. From the simulated received power, the extra losses of...
