Customized long range LoRa module for smart water meter gas meter internet of things
The features of HAC-ML are shown as follow: Long Range Transmission, Low Power Consumption, Small Size, High Reliability, Easy Expansion, Simple Maintenance and High Successful rate for meter reading. By using TDMA communication mode, HAC-ML system can synchronize the communication time unit automatically. By using frequency hopping technology, HAC-ML system can avoid Co-channel interference and enhance the transmission reliability. By using the auto adaptive algorithm, it enhances the system capacity of HAC-ML system effectively.
HAC-ML system includes three necessary parts, i.e. Wireless collecting module HAC-ML, Concentrator HAC-GW-L and Server iHAC-ML WEB. Users also can select the Handheld terminal or Repeater according to their project requirements.
