Survey of the low power wide area network technologies

Journal of Network and Computer Applications, 2020
Abstract With the number of connected devices in Internet of Things (IoT) increasing, the requirements for connectivity (e.g., battery life, deployment cost and coverage) are evolving to ensure effective communication between these devices. The emerging low power wide area (LPWA) technologies pave a way to address the problem as they can provide ...

Modelling and analysis of low-power wide-area networks [PDF]

2017 IEEE International Conference on Communications (ICC), 2017
In this paper, we investigate the uplink transmission performance of low-power wide-area networks (LPWANs) with regards to coexisting radio modules using LoRa as an example. In doing so we adopt a new topology to model the network where the node locations of the network of focus (LoRa) follow a Poisson cluster process (PCP) while other coexisting ...

Low-Power Wide-Area Networks at the IETF

IEEE Communications Standards Magazine, 2017
A new breed of wireless technologies has emerged under the generic name of low-power, wide-area (LPWA), with a number of common characteristics that make these technologies uniquely suitable for Internet of Things (IoT) applications. These common characteristics include a power-optimized radio network, a simplified network topology, frame sizes in the ...

Low-power wide-area networks

Proceedings of the Workshop Program of the 19th International Conference on Distributed Computing and Networking, 2018
Low-Power Wide-Area Network (LPWAN) is an emerging network technology for Internet of Things (IoT) which offers long-range and wide-area communication at low-power. It thus overcomes the range limits and scalability challenges associated with traditional short range wireless sensor networks.
