The recent volatility of global energy markets has promoted the role of IoT in reducing costs, improving efficiency and even insulating against fluctuations in spot prices. Water utilities have also been subject to growing stresses in many regions, occasioned by arguably greater extremes of weather but more particularly increasing demand and tighter regulations over quality and management. While roll-out of smart metering is a common factor across energy and water utilities, IoT has also figured increasingly across the whole distribution pipeline for maintenance and quality control. Most of these utility IoT applications now require wireless communication, not usually because mobility is involved but because wired communications for multiple metering and sensor points would be too expensive or practically impossible. Low…
