A broadband nationwide network for public safety based on LTE is inevitable where shared or dedicated types of LTE-based public safety networks are possible. Current LTE services do not meet mission-critical requirements and several enhancements have been defined by 3GPP to address this in Releases 12 and 13. First responders are familiar with LMR and consider it to be a reliable technology with massive deployment everywhere. Therefore, it is expected that LMR will continue to exist alongside any new LTE-based broadband public safety network. Recent LTE releases (particularly Release 15) addressed the LMR-LTE interoperability issue and described comprehensive interworking facilities. New and upcoming features and services of LTE in Releases 14 and 15, such as mission-critical data, mission-critical video, and aerial user equipments, are also directly applicable to public safety. The paper endeavours to provide a quick yet meaningful review of all these issues. It also offers a look ahead at the new and rapidly advancing virtualization technologies, such as software-defined radio access network, and radio access network slicing, as enablers for future public safety networks.<\/jats:p>","DOI":"10.1155\/2019\/7810546","type":"journal-article","created":{"date-parts":[[2019,6,10]],"date-time":"2019-06-10T19:31:07Z","timestamp":1560195067000},"page":"1-17","source":"Crossref","is-referenced-by-count":9,"title":["LMR and LTE for Public Safety in 700\u2009MHz Spectrum"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1145-5604","authenticated-orcid":true,"given":"Aizaz U.","family":"Chaudhry","sequence":"first","affiliation":[{"name":"Department of Systems and Computer Engineering, Carleton University, Ottawa, Canada K1S 5B6"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roshdy H.
