Abstract
New verticals within the Internet of Things (IoT) paradigm such as smart cities, smart farming, or goods monitoring, among many others, are demanding strong requirements to the Radio Access Network (RAN) in terms of coverage, end-node’s power consumption, and scalability. The technologies employed so far to provide IoT scenarios with connectivity, e.g., wireless sensor network and cellular technologies, are not able to simultaneously cope with these three requirements. Thus, a novel solution known as Low Power - Wide Area Network (LP-WAN) has emerged as a promising alternative to provide with low-cost and low-power-consumption connectivity to end-nodes spread in a wide area. Concretely, the Long-Range Wide Area Network (LoRaWAN) technology is one of the LP-WAN platforms that is receiving greater attention from both the industry and the academia. For that reason, in this work, a comprehensive performance evaluation of LoRaWAN under different environmental conditions is presented. The results are obtained from three real scenarios, namely, urban, suburban, and rural, considering both dynamic and static conditions, hence a discussion about the most proper LoRaWAN physical-layer configuration for each scenario is provided. Besides, a theoretical coverage study is also conducted by the use of a radio planning tool considering topographic maps and a precise propagation model. From the attained results, it can be concluded that it is necessary to evaluate the propagation conditions of the deployment scenario prior to the system implantation in order to reach a compromise between the robustness of the network and the transmission data-rate.
Highlights
Low Power - Wide Area Networks (LP-WAN) have emerged as one of the most promisingInternet of Things (IoT) enabling technologies due to their advantages over other solutions such as short-range transmission technologies (e.g., WiFi, Bluetooth, IEEE 802.15.4-based protocols, etc.)or cellular communications [1,2]
We evaluate the performance of Long-Range Wide Area Network (LoRaWAN) under three well-defined conditions, namely, urban, suburban, and rural scenarios
Different LoRaWAN PHY layer configurations have been tested in three environments that are discriminated by their particular conditions against wireless transmissions
Summary
Low Power - Wide Area Networks (LP-WAN) have emerged as one of the most promisingInternet of Things (IoT) enabling technologies due to their advantages over other solutions such as short-range transmission technologies (e.g., WiFi, Bluetooth, IEEE 802.15.4-based protocols, etc.)or cellular communications [1,2]. The main characteristics and requirements that an IoT system presents are: (i) a reduced use of bandwidth; (ii) a limited number of messages per node per day; (iii) huge number of simultaneously-connected end-devices; (iv) long-range links; and (v) low-cost end-devices. The majority of these features are satisfied by the different LP-WAN platforms in the market [3]; they present important differences mostly related to their network architecture and the adopted business model.
