Smart water meters and other metering devices have been in use for over 10 years. To ensure this long lifetime, these battery-powered IoT devices must be power-optimized. In addition, there are often size constraints on the devices. This means that the components of the device must also be as small as possible. Last but not least, cost-efficiency is also an important issue for these types of devices. For some years now, smart water meters have been in use that ensure fully digital data transmission and help optimize water consumption.
The Integrated SIM was specially designed for use in low-power IoT devices. It has contributed to making these mostly battery-operated devices even more efficient and has thus been able to guarantee a longer service life.
Read how this use case successfully showed that the Integrated SIM is ready to be used in many IoT applications.
