WMRNET-I Power and Energy Meter AMR Solution


WMRNET-I is an self-organized wireless network system designed for smart Energy meter automated meter reading(AMR) which is consist of Data Concentrator APC910M and Node Transceiver APC220N or APC230N, It provides an reliable channel for meter terminal communication, The best of WMRNET-I are fully MESH connection and Node as router or repeat, no more equipment and device. WMRNET-I has different working frequency channel and NETID selection options, By different NETID, many WMRNET-I could work at the same frequency channel in the same area at the same time. The simplified communication protocols and EDAC coding are keeps the network running in high efficient and interference immunity.

The Node is easily to embedded into Energy meter as well as the Data Concentrator to integrated to wire connection or GSM/2G/3G devices. The mass Energy meters are supported by WMRNET-I, Single-phase meter, Three-phase meter, etc. For large data communication in resident community, industrial area, high-rise building and village reconstruction to realize an flexible intelligent infrastructure.
