Hello, I am using a few Xbee3 modules to form a Zigbee network for communication between devices. I discovered that it's possible to obtain the RSSI readings directly using the xbee.atcmd command on micropython. My end goal however is to obtain the SINR(signal to interference + noise ratio).
I don't think there's a built in function to obtain the SINR reading. Are there any suggestions on how I can go about this?
Thanks.
Dear Clifton, the radio receiver performance is indeed determined by the SINR. However, the measurement requires dedicated Radio tester or distortion analyzer. It is difficult to carry out the measurement in the field.
To overcome this, the RSSI values can be used . The IF processor chip makers provide the calibrated RSSI chart and the RSSI readings and the SINR have a linear relationship.
In cellular networks, RSSI is used to work out the proximity while deciding on hand-off It is a powerful signal.
