Who is Bluetooth?
Yes, the question is asked the right way. It doesn't necessarily
need to be asked WHAT.
Because:
The origin of the word derives from Harald II from Blatand
(blue-tooth), and was the surname of the Danish king. He was
admitted for always working with allies. This surname was
then taken up by engineers of Ericsson and attributed to this
project. Today Bluetooth is already supported by many considerable
manufacturers from the computer- and mobile world, and nearly
daily new Bluetooth-products are thrown into the market.

Bluetooth supports one asynchronous data channel, up to three
simultaneous synchronous channels for audio (language), or
one channel for asynchronous data communication and synchronous
audio transmission at the same time.
An audio channel supports 64 kBit/s synchronously in both
directions. The asynchronous data channel supports either
one asymmetrical mode with 723,2 kBit/s downstream and 57.6
kBit/s sending speed, or alternatively a symmetrical mode
with 433,9 kBit/s in both directions.
