M420
TRANSCEIVER
QUICK GUIDE
AQG-10120-01
The M420 transceiver is a full duplex FlexNet® transceiver intended for installation into a Sensus FlexNet® M420B or M420D
Base Station. By providing dual M420 transceivers, a single base station can simultaneously support communications for
both AMI meter reading systems and high value applications such as DA, DR, HAN, and lighting control while transmitting
and receiving in a 200 kHz band of spectrum. This bandwidth enables more dedicated channels and higher network traffic
capacity.
