Bluetooth wireless technology features low-bandwidth,
short-range connection between two devices enabled to receive the data. The
structure behind this technology is complicated, and the extent of operation is
implementation specific. Using Bluetooth is not difficult and allows many
useful features that enhance today's technology.
What Are the Functions of Bluetooth?
Cell Phones
In the world of cell
phone technology, a Bluetooth headset allows phone users to communicate
hands-free. The device has a sensitive microphone that will pick up the
conversation from the users and carry it to the person on the other end of the
call. Bluetooth attaches to the ear of the cell phone user and allows them to
hear what their caller is saying. Essentially, a Bluetooth device provides
access to users without touching their phone. The owner of the phone can answer
calls and speak freely.
Personal Computers
The nature of a Bluetooth design makes operation
with a personal computer powerful. Functions of a Bluetooth device on a PC are
vast. Because Bluetooth technology requires a low-bandwidth transmission, many
computer patrons adapt to it for communicating with people over the Internet.
For example, when making a video call via a Web cam, Bluetooth allows for
hands-free operation.
Cars
Bluetooth compatibility is a modern-day addition
to many car systems. It allows drivers to use hands-free communication devices
within the car, and many cars now include snap-in cradles for Bluetooth-enabled
phones.
