3. o Named after tenth-century Danish King Harald Blatand.
o Developed by Special Interest Group (SIG).
o Bluetooth wireless technology is a short range communication system intended to replace cables connecting portable or fixed electronic
devices.
o It provides the way to connect and exchange information between devices like PCs , Laptops ,Digital cameras , Mobile phones, etc.

4. • Wireless networking can be done.
• Bluetooth peripherals like printers, mice and Key Boards, Cell Phones, remote controls, hearing aids , Playstation, Etc
• Medical applications.
• Bluetooth car kit are also available. Certain data logging equipment transmits data to a computer via bluetooth.

5. o Bluetooth networking transmits data via low power radio waves.
o It operates in ISM band at 2.4 GHz (Exactly between 2.402GHz to 2.480 GHz).
o It can operate in noisy frequency environments as it uses a fast acknowledgement & frequency hopping scheme to make
the link robust.
o Bluetooth devices avoid interfering with other systems by sending weak signals of about 1mW.
o It can connect upto 8 devices simultaneously.
o When the devices are connected then they form a network called Personal Area network or Piconet.

6. o Bluetooth works very similarly to how Wi -Fi signals and radio signals work. Through radio waves.
o Bluetooth uses a band of 79 different frequencies (channels) which range from 2,4 -2,485 GHz. This
frequency interval is shared with industrial, scientific, and medical gadgets.
o But this won’t be a problem for you when you use Bluetooth. This is because the class 2 type Bluetooth
that exists in consumer devices such as phones and computers only have a range of around 10 m.
o Other types of Bluetooth are class 1 and 3. Class 1 is used in industry and has a range of around 100m
and class 3 is rarely used because of its short range of 1 m.

7. There are two main limitations of the current Bluetooth wireless standard:
Slow transfer rate
Susceptibility to interference

8.  Bluetooth is a mature technology.
 Bluetooth is a low-cost wireless technology.
 Bluetooth can be easily integrated into your products
 Although there are very few disadvantages,
 Bluetooth still remains the best for short range wireless technology.
 This Bluetooth technology will make a great evolution in the communication field.
 Blue tooth represents a great chance for sensor-networked architecture.
