As engineers come to grips with specifying the most appropriate Internet of Things solutions, a key consideration is the choice of communication system – usually a low power wide area network (LPWAN). The uninformed may assume that two-way LPWAN systems are better than one-way communication. However, many engineering applications such as water metering, do not usually require control of the device or even any communication back to the device. Moreover, two-way communication introduces complications around security and power management that should be considered.
This presentation explores the advantages of one-way sensing solutions and the refinements required to make them commercially and technically superior for certain applications. Taggle Systems’ one-way sensing solution is showcased. Taggle was founded by some of the same people who developed the first high-speed Wi-Fi chips, commercializing the development work completed at CSIRO. Their aim was to cover solution gaps that Wi-Fi couldn’t address. Taggle currently manages over 3 million water meter readings per day, making it one of the largest remote sensing operators in Australia and arguably the most successful IoT implementation to date
