Smart meters provide a complete overview of water, gas, heat and electricity consumption, being suitable for residential and commercial property management. These devices are mostly communicating according to wM-Bus standard over a relative short range. Therefore, a large-area reading of meters is not possible. Numerous gateways to wide area networks such as GSM/LTE would be required. This leads to immense costs.
By using LoRa®, cost-effective solutions can be provided. The LoRa® modulation is a perfect mean to increase the coverage of existing networks thanks to its Long Range and Low Power capabilities. A typical use case for the Range Extender is to collect wMBus messages from several utility meters and forward those over long distances into a LoRaWAN® network.
It allows a flexible configuration of calendar events for wM-Bus reception windows as well as device filtering by Manufacturer/Device ID. It includes a long life battery which ensures in combination with the new ultra-low power radio module iM881A-XL a life time of up to 10 years and more.
All data gathered can be stored in the cloud for remote analysis and processing. In this way the utility cost can be easily collected, time and effort for billing can be reduced, and energy efficiency can be optimized.
