Abstract
The systems and methods described herein are directed to techniques for improving battery life performance of end devices in resource monitoring systems which transmit data using low-power, wide area network (LPWAN) technologies. Further, the techniques include providing sensor interfaces in the end devices configured to communicate with multiple types of metrology sensors. Additionally, the systems and methods include techniques for reducing the size of a concentrator of a gateway device which receives resource measurement data from end devices. The reduced size of the concentrator results in smaller, more compact gateway devices that consume less energy and reduce heat dissipation experienced in gateway devices. The concentrator may comply with modular interface standards, and include two radios configured for transmitting 1-watt signals. Lastly, the systems and methods include techniques for fully redundant radio architecture within a gateway device, allowing for maximum range and minimizing downtime due to transmission overlap.
