BER: Bit Error Rate

Bit Error Rate (BER) is the ratio of received bits that contain errors. BER is usually expressed as ten to a negative power. For example, a transmission might have a BER of 10 to the minus 9, which indicates that, out of a billion bits transmitted, one bit was in error. Typically, the bits in error need to be re-transmitted, which may slow down communications.
