Reasons that May Affect the High Bit Error Rate

Reasons that May Affect the High Bit Error Rate

What is BER?

In digital transmission, the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion, or bit synchronization errors.

The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit error ratio is a unitless performance measure, often expressed as a percentage.

What is the reason that may affect Bit Error Rate?

Error codes are caused by the fact that decay changes the voltage of the signal during signal transmission, which causes the signal to be destroyed during transmission, resulting in error codes.
Noise, pulses caused by alternating current or lightning, transmission equipment failure, and other factors can cause bit errors (for example, the transmitted signal is 1 and the received is 0; vice versa).

1.Material selection of transceiver module.

2.Access to the radio frequency offset value (frequency offset);

3. Electromagnetic environment, interference at the same frequency, obstacles (partition walls), distance, transmission power of the mobile station;

4. Whether the power cord specification is stable or not. 

5. Environment and the radio temperature, the normal temperature is -30℃~+60℃.
