Because FEC does not require handshaking between the source and the destin
A Bluetooth device purchased in Europe should be equally at home operating in, say, Japan or the forward error correction ethernet US. Frequency RangeFor this reason, Bluetooth devices utilise the 2.4Ghz Industrial, forward error correction library Scientific, and Medical (ISM) frequency range. Throughout most of the world this band is free and unregulated. forward error correction pdf Notable exceptions include Japan, France and Spain where the bandwidth is reduced. These restrictions have been eliminated in both Japan and Spain. The French military have authority http://searchmobilecomputing.techtarget.com/definition/forward-error-correction over the 2.4Ghz band in French territory, but will also be relinquishing control as of 1st Jan 2001. Encouraged by the Bluetooth SIG, governments world-wide are now beginning to regulate the 2.4Ghz band, thus ensuring that it will remain available for unhindered use by Bluetooth appliances.Physical LayerThe Bluetooth hardware is comprised of a single http://ntrg.cs.tcd.ie/undergrad/4ba2.01/group3/technology.html 9*9mm chip. Inserted into any device it can communicate with any other Bluetooth device within a 10m radius, or up to 100m if an amplifier is used. The maximum data rate achievable by 1st generation technology is 1Mbps. Bluetooth appliances use Gaussian Frequency Shift Keying (GSSK) for radio frequency modulation. Judicious use of these modulation techniques should allow future generations to achieve a transfer rate of between 2 and 12Mbps.Noise ImmunityBluetooth was designed to operate in a noisy environment. Two powerful techniques equip it well for this purpose.Frequency Hop (FH) spread spectrum is a method which effectively divides the frequency band into a number of hop channels. A technology that quickly hops channels minimises potential interference. Bluetooth takes advantage of this technique by incorporating a fast frequency hopping technology with a nominal hopping rate of 1600 hops/second among 79 channels. After transmitting a packet each device hops to another frequency as determined by the master. The hopping sequence is unique to

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 forward error 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.
