By Ry Crozier on Apr 26, 2021 9:27AM May prove a useful input into air quality monitoring systems. Microwave backhaul links used by mobile network operators may be a useful input into air quality measurement after research led by Monash University found that signal transmission patterns could be used to identify haze or smoke pollution in an area. Led by Dr Adrien Guyot, a research fellow in Monash University’s Department of Civil Engineering, and involving the Australian Bureau of Meteorology (BoM) and Dutch researchers, the study “analysed radio link signal fluctuations during smoke events associated with the 2019-2020 Australian bushfires.” Radio links, as defined by the study, are “commercial microwave links (CMLs) [and] are the backbone of cellular communication networks.”
