A Study of 5G Network Performance: A Pilot Field Trial at the Main Skytrain Stations in Bangkok

Evaluating the Feasibility of Intelligent Blind Road Junction V2I Deployments

“…Several works demonstrate that in controlled scenarios LTE-V2X could uphold QoS metrics for advanced V2X use cases [20,21]. Recent works studying NR-V2X and its enhancements [22][23][24][25], also within private cellular networks, have shown very promising performance for the technology's capacity as a candidate wireless access technology for V2X communications. While C-V2X has significant potential as a V2X communications candidate, it is clear from previous studies that it is not yet ready to be deployed at scale for advanced use cases, such as teleoperation, due to the challenges associated with reliability in terms of upholding QoS metrics.…”

Revisiting 5G quality of service in Bangkok metropolitan region: BTS Skytrain station areas

“…In the first quarter of 2020, one of the leading mobile network operators (MNOs) in the Thai telecommunications industry, which was also the first winner of the frequency spectrum auction, made the official launch of 5G services. This was followed by the launch of 5G services by the second winner of the frequency spectrum auction a few months later [2], [3]. Following the conclusion of the auction for the use of the frequency spectrum, the following events took place in the frequency bands shown: n3 (1800 MHz), n28 (700 MHz), (26 GHz) [4].…”

“…In general, it is anticipated that 5G will theoretically deliver significant efficiencies in comparison to 4G (see Figure 1). Since it is capable of supporting a peak data rate of 20 Gbps for the downlink and 10 Gbps for the uplink, respectively [3], while the goals for the data rate are, for example, 100 Mbps and 50 Mbps for the downlink and the uplink, respectively. Furthermore, it may be able to support a peak data rate of 20 Gbps for the downlink and 10 Gbps for the uplink.…”

“…In the past, the multinational corporation Opensignal would publish its reports once a year about the QoS parameters spanning both DL and UL. However, each time the report has been published, it has been regarded with skepticism due to the fact that its methodology has been called into question, and some of the QoS values have appeared to be lower than the findings that have been tested by end-users in Thailand [3]. As a result, the present investigation was carried out in order to determine whether or not the findings from this study linked with the DL and UL speeds, as well as latency, are compatible with the report that was provided by Opensignal or whether they differ in certain respects.…”

“…With regard to the pertinent literature or earlier studies, they can be displayed as shown in Table 1 [3], [4], [8], [18]- [31]. The evaluation of updated 5G performance in Bangkok, Thailand, has not been carried out previously, despite the fact that there are a number of tasks linked with 5G performance evaluation.…”
