What is the bit error rate? How does it affect a remote control?

Detailed Answer

The bit error rate (BER) is the proportion of erroneous bits in received data; industrial remote controls typically require BER <10⁻³ (i.e., below one in a thousand). An excessively high BER causes: button response delay, lost action steps, and occasional false actuation. The LDER LD series meets the standard within 200 m, and frequency-hopping spread spectrum further reduces bit errors. Strong ambient electromagnetic interference raises the BER, which can be improved by adjusting the antenna position or switching to a lower band.
