Question

wats is bluetooth on a cellphone and how does it work??

Answer 1

Bluetooth is the trade name of a wireless transmission system that is used for short-range digital communication.

The bluetooth signal is at a different frequency from the wireless device to which it's attached. It was originally developed to allow the use of the cell phone to perform transactions, such as purchasing a product through a vending machine, and have the charges appear on your cell phone bill.

Later, more sophisticated uses of Bluetooth include wireless headsets for cell phones that allow the user to wear just a small earphone-type device to use and communicate on their cellphone.
