  Re: What is FEC in Bluetooth?
Answer
# 1		 FEC is the error correcting technique used in bluetooth. it
stands for forward error control( or check-- i suppose). in
this there is an BER(bit error rate) for a particular
transmission which tells about the permissibility of the
corrupted bits. if the BER is more than the average BER
(prescribed value) then the communication made is useless
and need to be made again. so the data frame packet is
regenerated from the corrupted data and used again.

  Re: What is FEC in Bluetooth?
Answer
# 2		 FEC is "Forward Error Correction".
FEC is a method of obtaining error control in data
transmission in which the source (transmitter) sends
redundant data and the destination (receiver) recognizes
only the portion of the data that contains no apparent
errors. Because FEC does not require handshaking between
the source and the destination, it can be used for
broadcasting of data to many destinations simultaneously
from a single source.
It enables a receiver to not only detect but also correct
errors in a transmission.
Although successful in reducing the number of
retransmissions, the overhead incurred by using FEC
significantly slows down transmissions and is therefore not
used in relatively noise free environments. Packet headers
are an exception to this as they always make use of FEC,
regardless of environmental factors.
