State of the Art in LP-WAN Solutions for Industrial IoT Services

Ramon Sanchez-Iborra et al. Sensors (Basel). .

Abstract

The emergence of low-cost connected devices is enabling a new wave of sensorization services. These services can be highly leveraged in industrial applications. However, the technologies employed so far for managing this kind of system do not fully cover the strict requirements of industrial networks, especially those regarding energy efficiency. In this article a novel paradigm, called Low-Power Wide Area Networking (LP-WAN), is explored. By means of a cellular-type architecture, LP-WAN-based solutions aim at fulfilling the reliability and efficiency challenges posed by long-term industrial networks. Thus, the most prominent LP-WAN solutions are reviewed, identifying and discussing the pros and cons of each of them. The focus is also on examining the current deployment state of these platforms in Spain. Although LP-WAN systems are at early stages of development, they represent a promising alternative for boosting future industrial IIoT (Industrial Internet of Things) networks and services.

Keywords: Industrial Internet of Things (IIoT); Internet of Things (IoT); Low-Power Wide Area Networks (LP-WAN); Machine-to-Machine (M2M) communications; wireless sensor networks.
