NETWORK TECHNOLOGIES News of Constrat, a water metering supplier deploying 7,000 water meters across Greece and working in partnership with Sigfox Hellas to bring this kind of connectivity, demonstrates the kind of scale some projects take on, and the subsequent challenges involved in ensuring 7,000 water meters are operating without disruption. I was curious to learn more, so I spoke to Dimitris Kantaros, Chief Operating Officer of Sigfox Hellas, the Greek operating arm of Sigfox 0G Technology. In conversation with Kantaros, he was keen to emphasise that he believed Sigfox 0G technology to be one of the best unlicensed LPWAN protocols in IoT right now, for its efficiency, scalability and resilience – but acknowledged there was no one technology to serve all sectors. “We’re trying to find the golden ratio here,” he said.
device,” Bradley explained. This is what Kigen provides.
eSIM technology is proving useful in allowing water suppliers to switch between profiles, rather than being confined to a physical SIM card. “You can also manage the lifecycle of those connectivity profiles over-the-air, so you can download a new profile,” Bradley added. The cost, quality of data, and deployment are driving this shift to using cellular technology, said Bradley. “Networks like NB-IoT and LTE-M can reach very hard to reach areas. If a water meter is somewhere covered in concrete, you can reach it with these technologies because the band that is used is quite flexible.” On being asked whether he thought there was a “one size fits all” solution, Bradley was diplomatic in his answer. “We just need to make sure that whatever the given company chooses is sustainable,” he said.
Sigfox 0G technology’s reach is vast. It provides connectivity for water metering
