In the world of smart water metering<\/strong>, NB-IoT connectivity<\/strong> is often discussed as the ideal solution for remote meter reading. Its deep coverage, low energy consumption, and integration with existing cellular networks make it particularly attractive for utilities developing large-scale AMI infrastructures.<\/p> But there is a question that deserves attention: What happens when the cellular network is temporarily unavailable?\u00a0 In these situations, even NB-IoT\u2013based remote reading systems may temporarily lose connectivity. Let\u2019s imagine a smart meter designed with a dual communication architecture<\/strong>:<\/p><\/p>\n\n NB-IoT<\/strong> as the primary channel for remote meter reading<\/p><\/li>\n\n\n\n Wireless M-Bus (wM-Bus)<\/strong> as the secondary channel for proximity data collection<\/p><\/li>\n<\/ul>\n\n Under normal conditions, the meter communicates with the central system via NB-IoT<\/strong>, enabling automatic readings and remote event management.<\/p> However, if the cellular network becomes temporarily unavailable, the meter can still be read via wM-Bus<\/strong>, using drive-by<\/strong> or walk-by<\/strong> modes.<\/p> This approach allows utilities to maintain access to data even during temporary cellular network outages<\/strong>, avoiding operational disruptions.<\/p><\/p>\n\n Integrating NB-IoT and wM-Bus<\/strong> in the same device offers several concrete advantages:<\/p><\/p>\n\n \u2714 Continuity of remote meter reading<\/strong> even during cellular network maintenance or outages In practice, this introduces a true concept of communication redundancy directly within the device<\/strong>.<\/p><\/p>\n\n For utilities investing in AMI systems with long life cycles<\/strong>, designing devices with hybrid communication architectures<\/strong>\u2014combining cellular IoT and local radio\u2014can make a significant difference in terms of long-term reliability<\/strong>.<\/p> NB-IoT<\/strong> provides scalability and nationwide coverage, while wM-Bus<\/strong> ensures a local communication channel always available for proximity data collection operations<\/strong>.<\/p> In other words: it\u2019s not about choosing one technology over the other, but about making them work together.<\/strong><\/p><\/p>\n\n This dual connectivity approach<\/strong> is the foundation of ElecTo SONIC<\/strong>,<\/a> the new smart meter developed by Maddalena. Once again, the company demonstrates its pioneering role in a multiprotocol approach<\/strong>\u2014a design philosophy aimed at integrating complementary communication technologies to ensure operational continuity and maximum reliability.<\/p> ElecTo SONIC<\/strong> integrates within the same device:<\/p><\/p>\n\n NB-IoT<\/strong> as the primary communication channel<\/p><\/li>\n\n\n\n Wireless M-Bus<\/strong> as the local radio fallback channel<\/p><\/li>\n<\/ul>\n\n This is an approach that Maddalena adopted early in the sector<\/strong>, having previously developed multiprotocol solutions based on LoRaWAN and Wireless M-Bus<\/strong>. A vision that was internationally recognized in 2017 with the Global Technology Leadership Award<\/a><\/strong> assigned by Frost & Sullivan<\/span><\/span>.<\/p><\/p>\n\n In this way, even in the event of a temporary unavailability of the cellular network<\/strong>, the meter remains accessible for data collection, ensuring operational continuity and greater resilience of the metering infrastructure<\/strong> for utilities.<\/p><\/p>\n\n In critical infrastructures<\/strong>, such as water distribution systems, data reliability is essential<\/strong>. This is precisely the logic driving the evolution of smart metering systems<\/strong>: not relying on a single technology, but integrating different solutions to make infrastructure more robust and reliable over time<\/strong>.\n
