LPWAN technologies impacted by noise on the ISM band focusing on LoRa and Sigfox

Take a look at this interesting article from researchers at the Department of Electronic Systems at University of Aalborg, Denmark, on interference in the European 868MHz ISM band.

The study focuses on LoRa and Sigfox and it shows quite clearly that the LPWAN technologies with their long range due to their very sensitive receivers will be more susceptible to noise than other technologies like Mesh networks. In a Mesh network like NeoMesh, where devices communicate hop-to-hop through the network, the radio links are less susceptible to noise since the wanted signal levels are generally higher due to the shorter distance between devices.
The noise levels reported in the article will reduce the effective range of LPWAN devices, and as such make them impractical in certain applications. Good for developers to know when deciding on what wireless technology to select for a product.

The study has been published at the 2017 IEEE Wireless and Networking Conference (WCNC) that was held in San Francisco in March.
