Abstract: With the popularization of Internet-of-things (IoT) and wireless communication systems, a diverse set of applications in smart cities are emerging to improve the city-life. These applications usually require a large coverage area and minimal operation and maintenance cost. To this end, the recently emerging backscatter communication (BC) is gaining interest in both industry and academia as a new communication paradigm that provides high energy efficient communications that may even work in a battery-less mode and, thus, it is well suited for smart city applications. However, the coverage of BC in urban area deployments is not available, and the feasibility of its utilization for smart city applications is not known. In this article, we present a comprehensive coverage study of a Citation: Sheikh, M.U.; Xie, B.; practical cellular carrier-based BC system for indoor and outdoor scenarios in a downtown area of a Ruttik, K.; Yi˘gitler, H.; Jäntti, R.; Helsinki city.
