60-GHz Millimeter-Wave Propagation Inside Bus: Measurement, Modeling, Simulation, and Performance Analysis

Abstract

Millimeter-wave (mmWave) transmission over the unlicensed 60-GHz spectrum is a potential solution to realize high-speed internet access, even inside mass transit vehicles. The solution involves communication between users and a mmWave-band on-board unit that aggregates/disseminates data streams from/to commuters and maintains the connection with the nearest terrestrial network infrastructure node. In this paper, we provide a measurement-based channel model for the 60-GHz mmWave propagation inside a typical inter-city bus. The model characterizes power delay profile (PDP) of the wireless intra-vehicular channel, and it is derived from about 1000 data sets measured within the bus. The proposed analytical model is further translated into a simple simulation algorithm that generates in-vehicle channel PDPs. Different goodness-of-fit tests confirm that the simulated PDPs are in good agreement with the measured data. Finally, a tapped-delay-line (TDL) channel model is formulated from the proposed PDP model, and the TDL model is used to study the bit error rate (BER) performance of the mmWave link inside bus under varying data rates and link lengths.INDEX TERMS Intra-vehicular communication, 60 GHz channel sounding, power delay profile, tapped delay line, bit error rate.

Multi-Frequency Multi-Scenario Millimeter Wave MIMO Channel Measurements and Modeling for B5G Wireless Communication Systems

“…In this paper, channel measurements have been conducted with 4×4 MIMO antenna configurations at multi-frequency mmWave bands (28,32, and 39 GHz) and in multi-scenarios for B5G wireless communication systems. The detailed measurement and modeling results have been analyzed.…”

“…The QuaDRiGa open source model was extended and applied to the mmWave channel modeling. In [16], 28 GHz channel measurements were conducted in outdoor courtyard scenario with rotated arXiv:2007.13973v1 [eess.SP] 28 Jul 2020 horn antennas to obtain the path loss model. In [17], [18], channel measurements were conducted at 28 GHz and 39 GHz in outdoor urban macro (UMa) and urban micro (UMi) environments.…”

Millimeter-Wave Channel Modeling in a Vehicular Ad-Hoc Network Using Bose–Chaudhuri–Hocquenghem (BCH) Code

“…The TDL model was used for a bit error study of millimeter-wave by varying data rates and link length. Since millimeter waves cannot penetrate walls, a relay device is required to redirect signals [7]. In [8] bit error rate probability was evaluated for interference in a multi-hop millimeter-wave system.…”

Channel Propagation Characteristics for the Communications Inside Tower Structure Buildings

“…However, there are few studies for the inside of tower structures. Considering that tower structure is a special case of indoor scene, and some indoor channel models are worthy of references [8][9][10][11][12]. The channel model and channel characteristics were studied in metro train based on the ray tracing (RT) method at 26.5-40 GHz [9], and the validity of proposed model was verified by the measured data.…”
