What Can 5G Do for Public Safety? Structural Health Monitoring and Earthquake Early Warning Scenarios

Abstract

The 5th generation of mobile networks has come to the market bringing the promise of disruptive performances as low latency, availability and reliability, imposing the development of the so-called “killer applications”. This contribution presents a 5G use case in the context of Structural Health Monitoring which guarantees an unprecedented level of reliability when exploited for public safety purposes as Earthquake Early Warning. The interest on this topic is at first justified through a deep market analysis, and subsequently declined in terms of public safety benefits. A specific sensor board, guaranteeing real-time processing and 5G connectivity, is presented as the foundation on which the architecture of the network is designed and developed. Advantages of 5G-enabled urban safety are then discussed and proven in the experimentation results, showing that the proposed architecture guarantees lower latency delays and overcome the impairments of cloud solutions especially in terms of delays variability.

Developing and Testing High-Performance SHM Sensors Mounting Low-Noise MEMS Accelerometers

“…The IT architecture designed and developed is an enhanced version of the solutions and methodologies employed in previous years for acquiring and processing data from accelerometers, inclinometers, crackmeters, and temperature sensors dedicated to structural monitoring. The described solution adheres to the micro-services architecture and, in a subsequent phase, was restructured within a cloud framework towards edge-computing [ 36 ]. Figure 3 shows the proposed service architecture.…”

A network application approach towards 5G and beyond critical communications use cases

“…While appropriate standards for the support of PPDR services were described in Release 15 of the 3GPP specifications, including Mission Critical Push To Talk (MCPTT) (third Generation Partnership Project, 2017a), Mission Critical Video (MCVideo) (third Generation Partnership Project, 2017b) and Mission Critical Data (MCData) (third Generation Partnership Project, 2018), EU public safety organisations continue to rely on legacy PPDR networks, such as TETRA, TETRAPOL, P25, and DMR (Neto et al, 2022). To incentivise a transition of PPDR services to commercial broadband networks, the benefits of 5G technology for this vertical are well-documented in the scientific literature (Franchi et al, 2022;Borsatti et al, 2023), as have several frameworks, tools, innovative systems and research projects, to address service requirements in the sector (Apostolakis et al, 2021;Arampatzis et al, 2021;Chochliouros et al, 2021;Margetis et al, 2022;Sterle et al, 2022). Therefore, research focus has now shifted towards delivering reliable and unquestionable experimental evidence regarding the practical offerings of 5G to critical communications use cases (Volk and Sterle, 2021;Borsatti et al, 2023).…”

Global Models of Smart Cities and Potential IoT Applications: A Review

“…Public health monitoring devices monitor air quality, detect pathogens, and track the spread of diseases, which can help prevent outbreaks and protect public health. These devices are essentially used to protect and improve the health and safety of individuals and communities [99]. The public health monitoring applications involve:…”
