As part of these efforts, migrating from traditional land mobile radio (LMR) systems toward cellular-enabled, next-generation, mission-critical networks is at the top of these agencies\u2019 agendas. In this paper, we provide an overview of cellular technologies ratified by the 3rd Generation Partnership Project (3GPP) to enable next-generation public safety networks. On top of using wireless communication technologies, emergency first responders need to be equipped with advanced devices to develop situational awareness. Therefore, we introduce the concept of the Internet of Life-Saving Things (IoLST) and focus on the role of wearable devices\u2014more precisely, cellular-enabled wearables, in creating new solutions for enhanced public safety operations. Finally, we conduct a performance evaluation of wearable-based, mission-critical applications. So far, most of the mission-critical service evaluations target latency performance without taking into account reliability requirements. In our evaluation, we examine the impact of device- and application-related parameters on the latency and the reliability performance. We also identify major future considerations for better support of the studied requirements in next-generation public safety networks.<\/jats:p>","DOI":"10.3390\/s21175790","type":"journal-article","created":{"date-parts":[[2021,8,31]],"date-time":"2021-08-31T22:58:15Z","timestamp":1630450695000},"page":"5790","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Enabling Next-Generation Public Safety Operations with Mission-Critical Networks and Wearable Applications"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2786-9377","authenticated-orcid":false,"given":"Salwa","family":"Saafi","sequence":"first","affiliation":[{"name":"Department of Telecommunications, Faculty of Electrical Engineering and Communication, Brno University of Technology, Technicka 12, 616 00 Brno, Czech Republic"},{"name":"Unit of Electrical Engineering, Faculty of Information Technology and Communication Sciences, Tampere University, 33720 Tampere, Finland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8382-9185","authenticated-orcid":false,"given":"Jiri","family":"Hosek","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Faculty of Electrical Engineering and Communication, Brno University of Technology, Technicka 12, 616 00 Brno, Czech Republic"}]},{"given":"Aneta","family":"Kolackova","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Faculty of Electrical Engineering and Communication, Brno University of Technology, Technicka 12, 616 00 Brno, Czech Republic"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"70397","DOI":"10.1109\/ACCESS.2018.2879760","article-title":"Survey of public safety communications: User-side and network-side solutions and future directions","volume":"6","author":"Yu","year":"2018","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"7810546","DOI":"10.1155\/2019\/7810546","article-title":"LMR and LTE for public safety in 700 MHz spectrum","volume":"2019","author":"Chaudhry","year":"2019","journal-title":"Wirel.
