Detailed Answer
Receiver sensitivity is the minimum signal strength the receiver can correctly demodulate, in dBm — the smaller the number, the more sensitive. Industrial-grade receiver sensitivity is typically -105 to -120 dBm. The LDER LD series has a receiver sensitivity of about -110 dBm, achieving 200 m communication at 10 mW transmit power. Sensitivity is affected by RF front-end design and antenna matching. When comparing specs, make sure test conditions are consistent, and evaluating sensitivity together with the bit error rate (BER) is more meaningful.
| Industrial grade | -105~-120dBm |
| LDER | approx. -110dBm |
| Correlation | BER |
Note:The smaller the sensitivity value the better, but evaluate it together with the bit error rate.
