WMRNET-III is an self-organizing wireless network system designed for Water meter and Gas meter automated meter reading(AMR) which is consist of Data Concentrator APC930M and Node Transceiver APC240N or APC240F, It provides an reliable channel for meter terminal communication, The best of WMRNET-III is ultra power saving technology in nodes, Nodes duration life could last more than 10 years by battery-powered, the total cost in Node’s entire life cycle could be deeply reduced.

What’s more, WMRNET-III fully MESH connection makes the Node communication as router or repeat, no more equipment and device. WMRNET-III has different working frequency channel and NETID selection options, By different NETID, many WMRNET-III 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 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-III meet the mainstream market requirements.
