“…Regarding the Train-to-Ground link for high-speed trains, a very complete reference is [5] but it is focused on frequencies below 6 GHz; for tunnels which are a very common scenario in railways, there are many papers, like [6,7]; inside metro stations there are many research papers like [8]; and for mm-wave research in railways there are some ray-tracing simulations in mm-wave and THz [9]. For intratrain link, there are some recent papers but below 6 GHz [10,11]. The structure of the paper is the following: in Section 2 we will describe the experiment setup, covering the environment details, the measurement setup, and the processing of the data; in Section 3 we will explain all the results obtained from the measurements, and, finally, in Section 4 a conclusion and some discussion are provided.…”

Passenger trains and especially metro trains have been identified as one of the key scenarios for 5G deployments. The wireless channel inside a train car is reported in the frequency range between 26.5 GHz and 40 GHz. These bands have received a lot of interest for high-density scenarios with a high-traffic demand, two of the most relevant aspects of a 5G network. In this paper we provide a full description of the wideband channel estimating Power-Delay Profiles (PDP), Saleh-Valenzuela model parameters, time-of-arrival (TOA) ranging, and path-loss results. Moreover, the performance of an automatic clustering algorithm is evaluated. The results show a remarkable degree of coherence and general conclusions are obtained.

“…According to them, this is appropriate for ETCS L2 because a braking phase on the track determines the minimum headway time. Still, encouraged by rapid progress in commercial mobile communication technology, a recently conducted research [50][51][52][53][54] has changed the focus on new potential technologies that could replace GSM-R in the future. Currently, a Future Railway Mobile Communication System (FRMCS) based on 5G technology has the highest potential to succeed the GSM-R.…”

In times of ever stronger awareness of environmental protection and potentiation of a beneficial modal split, the railway sector with efficient asset utilization and proper investment planning has the highest chance of meeting customer expectations and attracting new users more effectively. Continuous increase in railway demand leads to an increase in the utilization of railway infrastructure, and the inevitable lack of capacity, a burning problem that many national railways are continually facing. To address it more effectively, this paper reviews available methodologies for railway capacity determination and techniques for its enhancement in the recent scientific literature. Particular focus is given to the possibility of increasing railway capacity through signalling systems and installing the European Train Control System (ETCS). The most important relationships with segments of existing research have been identified, and in line with this, the directions for a potential continuation of research are suggested.

“…This latter system can be even split into two: one for mission critical data and the other for non-mission critical data. However, another approach consists of using one communication system [7]. Indeed, with 5G, a single network can be used for all types of data with appropriate network slicing through software defined networking (SDN) and network function virtualization (NFV) [8].…”

“…[9], in order to characterize the propagation of these waves in different conditions (tunnels, rural and urban scenarios, straight and curved routes). Although they are suited for communication between RRHs and MRs, mmWave frequencies might be best suited for an mMTC slice dedicated for transmission of train control and management system (TCMS) information between sensors and RRHs (both fixed along the track, such that LOS can be easily maintained) or between sensors inside the train measuring train parameters and the internal train communication network [7]. Sub-6Ghz bands can be used for longer range connectivity between MRs and macro BSs.…”

<b>To meet the increasing demands for passenger data rates, modern railway communication networks face significant challenges. The advent of 5G communications after the long-term evolution (LTE) and LTE-Advanced (LTE-A) systems provides several technological advances to address these challenges. In this paper, after reviewing the main 5G communication aspects for modern railways, we present methods to ensure connectivity and energy efficiency for the passengers' user equipment (UE) through the use of mobile relays (MRs) on top of the train wagons in conjunction with intelligent resource allocation. Relevant challenges to train connectivity are also presented, and suitable solutions are outlined.</b>
