bluetooth is like infra red but its not a beam but waves
the same as ur microwave waves. the range of bluetooth is
10 meters, its very slow and is one way (like radieo, when
u wanna talk u have to pres button => u talk, or u listen
not both, not like phones where both persons can talk in
the same time). and it does not depend on gsm connectivity.

laptops, car radio, etc. most importanthe bluetooth is a
free frequency.
