What is FEC?


Forward Error Correction. Google it :-)



Just to add to Mike's comment, FEC works by send the same message several
times- in simple terms, in the hope that one with get through correctly. It
is simple to implement, your recieving system just needs to be able to
identify a correct message and use it, not spot a bad message and initiate
either a request for resend or applly some sort of correction method
(assuming there is error correcting code in the message).
