ARROW NB-IoT RADIO MODULE
Images for demonstration purposes only: elements may vary
NB-IoT Radio Module available in a compact version with inductive sensor for direct mounting on the meter, or in a separate version with pulse input to upgrade any compatible pulse-output meter to a smart device. Data communication uses a low-latency UDP protocol with wM-Bus application layer compliant with EN 13757-8:2023, ensuring interoperability and reliability.
NB-IoT connectivity provides long-range coverage via the 4G cellular network, both in urban and suburban environments. Battery-powered operation ensures up to 10 years of autonomy, depending on configuration and transmission frequency.
Activation and configuration are performed via NFC interface using a dedicated Android app or through OTA (Over-The-Air) mode.
