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. Five radio
transmission data rates are available: 9.6 kb/s, 19.2 kb/s, 38.4 kb/s, 76.8 kb/s and 153.6
kb/s. The transmission power of the 915 MHz radio is adjustable from 20 dBm to -20
dBm.
