Wireless Technologies and the SAFECOM Sor for Public Safety Communications
Wireless Technologies and the SAFECOM SoR for Public Safety Communications Leonard E. Miller Wireless Communication Technologies Group Advanced Network Technologies Division Information Technology Laboratory National Institute of Standards and Technology Gaithersburg, Maryland 2005 Cover photo: Santa Clara County antenna farm, from http://www.sccfd.org/frequencies.html ii Wireless Technologies and the SAFECOM SoR for Public Safety Communications Preface The Problem: Lack of Capacity, Interoperability, and Functionality National assessments of public safety communications (PSC) that were made in the 1990s found that the nation’s public safety agencies faced several important problems in their use of radio communications1: • First, the radio frequencies allocated for Public Safety use have become highly congested in many, especially urban, areas…. • Second, the ability of officials from different Public Safety agencies to communicate with each other is limited…. Interoperability is hampered by the use of multiple frequency bands, incompatible radio equipment, and a lack of standardization in repeater spacing and transmission formats. • Finally, Public Safety agencies have not been able to implement advanced features to aid in their mission. A wide variety of technologies—both existing and under development —hold substantial promise to reduce danger to Public Safety personnel and to achieve greater efficiencies in the performance of their duties. Broadband data systems, for example, offer greater access to databases and information that can save lives and contribute to keeping criminals “off the street.” Video systems promise better surveillance capabilities, increased use of robotics in toxic and hazardous environments, and better monitoring and tracking of both personnel and equipment. The national assessments of PSC have had significant impact on legislation, regulation, and funding. -

In this paper, we present a detailed survey of various resource allocation schemes that have been considered for the cellular network’s operation in the unlicensed spectrum. The key channel access mechanisms for cellular network’s operation in the unlicensed bands are discussed. The various channel selection techniques are explored and their operation explained. The prime issue of fairness between cellular and Wi-Fi networks is discussed, along with suitable resource allocation techniques that help in achieving this fairness. We analyze the coverage, capacity, and impact of coordination in LTE-U systems. Furthermore, we study and discuss the impact and discussed the impact of various traffic type, environments, latency, handover, and scenarios on LTE-U’s performance. The new upcoming 5G New Radio and MulteFire is briefly described along with some of the critical aspects of LTE-U which require further research. -
