WMRNET-IV is an self organized wireless network system designed for Water meter and Gas meter automated meter reading(AMR) which is consist of Data Concentrator APC950, Router and Node Transceiver APC340F, It provides an reliable channel for meter terminal communication, The best of WMRNET-IV are power saving technology and ultra long range covers, Nodes duration life could last to 10 years by battery-powered, the total cost in Node’s entire life cycle could be deeply reduced. What’s more, By LoRa Spread Spectrum technology, the Node interference immunity, covers distance and penetrating ability tops all RF products.

WMRNET-IV adopts an composited topology with MESH and STAR connection, Nodes only connect to Router as an STAR, then all Routers connected as an MESH to communicate with Data Concentrator. WMRNET-IV has different working frequency channel and NETID selection options, By different NETID, many WMRNET-IV could work at the same frequency channel in the same area at the same time. The WMRNET-IV is best for Large or mass resident community, Industrial area and Building groups.

The Node is easily to embedded into Water meter and Gas meter as well as the Data Concentrator to integrated to wire connection or GSM/2G/3G devices. Meanwhile, Impulse sensor meter and Optical sensor meter are well supported by Node to make WMRNET-IV meet the mainstream market requirements.
