1 About the RFW-201 The RFW-201 is a radio communications device designed for use in water meters. The RFW-201 provides a 915 MHz radio interface to an RF mesh network. The RFW-201 operates from a 3.6V lithium battery. The supplied voltage is then regulated to 3.3VDC by the on-board power supply circuit. The radio module operates in license-free bands at 915 MHz (902.75 to 927.25 MHz). RFW-201 Nodes are fully compatible with mesh network hardware, protocols and operations.
