What does FEC mean in Bluetooth?

- FEC stands for Forward Error Correction. On the data payload, FEC reducing the number of retransmissions.

- Within blue tooth, there are 2 versions namely, 1/3 FEC and 2/3 FEC.

- The 1/3 version is 3 times repetition of each information bit.

- The 2/3 version is a shortened Hamming code.

- It is known as a method of obtaining error control in data transmission in which the source sends redundant data and the destination will recognize it without the errors.

- They are used for broadcasting to many destinations from a single source.
