Bluetooth is a wireless technology developed in 1994 by Ericsson to allow electronic devices to communicate wirelessly within short ranges of up to 30 feet. It eliminates the need for cables and adapters between devices. The Bluetooth Special Interest Group was formed to develop the technology further. Bluetooth devices include headsets, printers, cameras, and more. It has advantages like low power consumption and cost but disadvantages like lower data rates, limited range, and security issues compared to WiFi.

2. What is BLUETOOTH:
Bluetooth is a wireless technology used to
transfer data between different electronic
devices. This technology eradicates the
use of cords, cables, adapters and
permits the electronic devices to
communicate wirelessly among each
other.
(or)
Bluetooth is a high-speed, low-power
microwave wireless link technology,
designed to connect phones, laptops,
PDAs and other portable equipment
together with little or no work by the user.

3. Who Started Bluetooth?
 Bluetooth was invented in 1994 by Ericsson.
 The company later started working with a larger group of companies
called the Bluetooth Special Interests Group, or "SIG," to
develop the technology into what it is today.
Bluetooth Special Interest Group (SIG)
5 founding members
Ericsson, Nokia, IBM, Intel & Toshiba
 Bluetooth is not owned by any one company and is developed and
maintained by SIG.
 The name Bluetooth came from a code name originally used by SIG for
the project and is a reference to a 10th century Danish king named
Harold Bluetooth, who was responsible for uniting Norway, Sweden,
and Denmark.
 Promoter’s Group
3COM, Lucent, Microsoft, Motorola
 • Now over 1900 members

4. It comprises of a base band processor, a radio and an antenna . The base-band
processor converts the data into signals, the antenna of another blue tooth
device, within at least 30 feet distance, receives a transmitted signal in the air.

10. ADVATAGES OF BLUETOOTH:
 These have Replaced cables for transferring Information
from one Electronic Device to another one.
 These have decreased Strain like carrying phones while
talking, making hands free to do another work.
 This is cheaply Available.
 It’s Mobility is also very Important as it doesn’t need any
power outlet or Internet connection or any other items.

11. DISADVANTAGES OF
BLUETOOTH:
 Data sent between two Bluetooth devices is very slow
compared with Wi-Fi transfer Rate.
 Range Of a Bluetooth Device is 15-30 feet depending upon
the Device.
 Security is Biggest Disadvantage as transfer takes place
through radio waves and a hacker can easily hack it.
 Battery usage is also a problem, it will make device out of
power before it would have if Bluetooth was not powered on.
