It is a RF (2GHz) wireless communication protocol used for interfacing computer and its peripherals. The communication range is very small (few meters).
One "problem" with this system is that it was originally intended to replace cables between computers and peripherals. The cost has not dropped to the predicted low level and so it is not cost competitive with cables.
The other problem is the protocol which only allows a closed network. The market for short range wireless connectivity wants roaming nodes to be able to get into the closest network.
Another problem is the "crashing" of networks which consumers will not accept. No one wants to be a computer expert and reboot systems just to make their wireless headsets play music from their hi fi sets.
A wireless communication between devices of small range to pass over the data, specification says that it is 100 mts range but practicaaly works less than 50 mts.
hi miss marwa i am hatem
all what you need to know about bluetooth is it is a small device have a sample protocal to connect with a 7 device at the same time without wires and it has a higth security in transfar data with rate 700kps:idea:
