WebbShannon's channel coding theorem states that "the error rate of data transmitted over a bandwidth limited noisy channel can be reduced to an arbitrary small amount if the information rate is lower than the channel capacity." This theorem is the basis for error correcting codes using which we can achieve error-free transmission.
