Eppeltone RF Mesh (Wi-SUN) Communication Module for Smart Metering
Product Datasheet | Model: ECM-RFM-WISUN-DLMS
Overview The Eppeltone ECM-RFM-WISUN-DLMS is a high-performance wireless communication module based on Wi-SUN (Wireless Smart Utility Network) standards. Engineered for smart grid applications, it facilitates secure, low-power, mesh-based connectivity across electricity, gas, and water metering infrastructures.
Designed for compatibility with third-party DLMS/COSEM and IEC 62056-based meters, this module is tailored for rugged outdoor deployments across India, Europe, and the Middle East. It is field-proven in high-noise RF environments and delivers superior performance in both urban and rural utility networks.
