This document presents information about Bluetooth technology. It provides an overview of Bluetooth, describing how it works as a wireless standard for exchanging data over short distances. It details how Bluetooth devices connect to form personal area networks, and lists some common application scenarios like synchronization and wireless headsets. Finally, it discusses some advantages of Bluetooth like replacing cables, and disadvantages such as limited range and security issues.

3. wireless technology standard for exchanging
data over short distances
Provides a easy way to connect and exchange
information between different devices such as
faxes, mobile phones, Digital camera, video
game consoler e.t.c.
Invented by telecom vendor Ericsson in 1994
It operates in the range of 2400-2483.5 MHZ and
with atleast 30 feet distance.

4. Each bletooth device has a unique 48-bit
address.
Originally concieved as a cable replacement
technology

5. I am King Harold
Bluetooth who unified
warringVikingTribes in
the 10th Century. In the
21st Century a wireless
Bluetooth network is
named after me.

6. Cable
Replacement
Personal Ad-hoc
Networks
(Also known as
Piconets)

7. Inquiry Procedure( Hello, Anyone Around?)
 Sends out an inquire, which is a request for nearby
devices (within 10 meters)
 Devices that allow themselves to be discoverable
issue an inquiry response
 Can take up to 10.24 seconds, after which the
inquiring device should know everyone within 10
meters of itself

8. Then forms a Piconets where each devices
acting as a master/slave configuration.
Generally known as master, initiator of the
connection and who gives respose is a slave
But can switch roles i.e, the slave can become
the master (for example, a headset initiating a
connection to a phone will necessarily begin as
master, as initiator of the connection; but may
subsequently prefer to be slave).

9. 1. Host Controller Interface (HCI)
 provides a common interface between the Bluetooth host and a
Bluetooth module
2. Link Layer Control & Adaptation (L2CAP)
 A simple data link protocol on top of the baseband, also a
connection-oriented & connectionless
3. RFCOMM (based on GSMTS07.10)
 emulates a serial-port to support a large base of legacy (serial-port-based)
applications
4. Legacy protocol reuse
 resuse existing protocols, e.g., IrDA’s OBEX, or WAP for interacting with
applications on phones
5. Service Discovery Protocol (SDP)
Defines an inquiry/response protocol for discovering services 7

10. 1.Synchronization
Automatic synchronization of calendars,
address books, business cards.

11. 2.Ultimate Headset
Multiple device access.
Hands-free operation
Keep your hands free for
 Car
 Office
 Road

12. 3.Conference Table
Share and exchange data
4. Computer Speakerphone
5.Cordless Computer

13. 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 cheaplyAvailable.

14.  Data sent between two Bluetooth devices is
very slow compared withWi-Fi transfer Rate.
 Range Of a Bluetooth Device is max of 30 feet
depending upon the Device.
 Security is Biggest Disadvantage as transfer
takes place through radio waves and a hacker
can easily hack it.
