I also faced this Question!!     Answer Posted By  
 
Answer
# 1
This is a wireless technology designed to transfer files,
between variuos devices. Like, mobile to mobile, mobile to
computer or vive-versa. It works in the range of 10 meters
approx. It is not very secure mode of transmission as
someone can steal the information.

IR (infrared) is also used for the same purpose, but works
in very small range.

hi friends..!!!

my name is vinay savant from bangalore,
BE E&C, 9886545929.

blue tooth is nothing but is a wire less communication
medium and it is a higher version of infrared technology.
which will work at the frequency range of 2 to 5 mega hz
and coverage of around 100 meters. now a day all the pc to
pc communication is enabled by blue tooth tech and even
mobile data can be transfered through this technology. blue
tooth uses the 802.11X standards.

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.

Bluetooth is a low power wireless technology. It works in
unlicensed band of 2.4GHz. The minimum specified range for
Bluetooth is 10m.
It uses Frequency hopping technique to avoid interference
and uses time division multiplex for communication.
The device which initiates the connection is called master,
all other devices (max 7) called slves tune to masters
frequency and time to form piconet.
Three are various versions more popular once are Bluetooth
1.2 ,2.0,2.1 and now 3.0.
Over a period of time Bluetooth has evolved as as high speed
low power technology.

Bluetooth is an open wireless protocol for exchanging data over short distances (using short length radio waves) from fixed and mobile devices, creating personal area networks (PANs). It was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
Bluetooth is a standard and a communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 100m, 10m and 1m, but ranges vary in practice; see table below) based on low-cost transceiver microchips in each device. Bluetooth makes it possible for these devices to communicate with each other when they are in range. Because the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other.
