This OID stores the received power in decibel-milliwatt (dBm) format as a readable text string, typically ranging from -40 to +8.2 dBm. Network engineers use this to quickly assess whether the remote transmitter is sending adequate signal strength without needing to convert raw binary values. A value of '-10.5 dBm' means the receiver is detecting a reasonably strong signal with good margin above the typical -20 dBm sensitivity threshold.
