“…The mmW communication system is also a candidate for the system offering highspeed communication services in HSR. The Distributed Antenna System based the 28 GHz millimeter Wave mobile communication system for HSRs analyzed the potential of the system through the computer simulations, showing that the enormous throughput exceeding 2 Gbps can be achieved in the HSR moving at a speed of 400 km/h [21].…”

The new generation of capsules that circulate through vacuum tubes at speeds up to 1200 km/h, which is being developed, demands communication systems that can operate at these speeds with high capacity and quality of service. Currently, the two technologies available are the new generation of 802.11ax networks and 5G NR. Using these technologies at such high speeds in a confined environment requires a careful study and design of the configuration of the network and optimization of the physical interface. This paper describes the requirements for critical and business communications, proposing a WLAN and 5G network design based on the analysis of the propagation characteristics and constraints of vacuum tubes and using propagation measurements and simulations made in similar environments at frequencies of 2.5/5.7/24 GHz. These measurements and simulations show that propagation losses in this environment are low (4–5 dB/100 m), as a consequence of the guided propagation, so that the use of bands is preferred. Finally, considering the propagation constraints and requirements of a Hyperloop system, a complete wireless communication system is proposed using two networks with 802.11 and 5G technology.

“…Besides, the research on mmWave bands used in train‐to‐infrastructure has been conducted. The authors in [24] reviewed the architecture design of a train‐to‐infrastructure (T2I) mmWave communication system. The mmWave has such a broad application prospect, and whether it can be applied in the vacuum tube scene is also worthy of attention.…”

A reliable train-to-ground wireless communication system is proposed for the foundation of the safe operation of Hyperloop. The wireless channel characteristics of Hyperloops at millimetre-wave (mmWave) bands are analysed based on the ray-tracing method. Considering the reflection paths and line of sight path, the channel transfer function expression is derived for each multipath and then the channel impulse response is obtained. On this basis, the investigation and analysis of the large-scale and small-scale channel characteristics, including the path loss, shadow fading, delay spread, and angular spread of 4 different mmWave frequency carriers, that is, 28/38/45/60 GHz, are conducted. Simulation results show that the path loss increases as the frequency increases while the time delay spread and angular spread almost keep unchanged. The relevant research results will contribute to the design of future Hyperloop wireless communication systems.

To acquire accurate channel characteristics for 5G New Radio (NR) vehicle-to-infrastructure (V2I) communications, in this paper, we propose a 5G passive channel measurement platform based on software defined radio devices and 5G user equipment. Different from active measurement platforms, the proposed measurement platform only requires a receiver and the channel state information reference signal (CSI-RS) periodically transmitted by the 5G commercial base stations is used as the measurement waveform. The channel impulse response can be computed based on the CSI-RS signal extracted from the received waveform and the standard CSI-RS signal generated according to the signaling information. By using the proposed 5G passive channel measurement platform, we carry out wireless channel measurement for V2I communications in typical urban scenarios. Further, based on the measurement, the small-scale channel fading characteristics including the power delay profile, the number of multipaths, the delay spread of multipaths, and the Ricean K-factor are analyzed.
