The document summarizes Bluetooth technology. It discusses how Bluetooth simplifies wireless data synchronization using short-range radio technology. It then describes the Bluetooth protocol stack including layers like the baseband, LMP, HCI, and various adopted protocols. The document outlines Bluetooth profiles and how they describe implementation of user models. It also provides an overview of Bluetooth modes of operation, versions, applications, advantages, security issues, and disadvantages.

1. Good morning
Welcome
to the
seminar

2. Seminar on
Bluetooth

3. Bluetooth
Simplifies
Open Uses short
data
wireless range radio
synchronisat
protocol technology
-ion

4. Bluetooth implementation
Developed
& licensed
Uses by SIG
Gaussian
Frequency
Uses shift keying
frequency
hopping
spread
spectrum

6. Bluetooth specification protocol stack

7. Bluetooth radio
 Frequency bands
Transmitter characteristics
Receiver characteristics
Baseband
 error correction
Hop selection
Bluetooth security

8. LMP
Used by link managers
Mainly made up
of PDU’s
HCI
Acts as a command
interface
Communicates the host
stack with the host
controller

9. L2CAP
Provides connection oriented
& connectionless
data services
Two link types
-SCO
-ACl
RFCOMM
Creates a virtual serial data
stream
Acts as a transport layer
Emulation of serial ports

10. SDP
Uses a request/response
model
Discovers services provided
by other Bluetooth devices
AVCTP
Audio/visual control
transport protocol
AVDTP
Audio/visual data transport
protocol

11. TCS-BIN
Telephony control protocol-binary
bit oriented protocol
ADOPTED
PROTOCOLS
It includes-
ppp
point-to-point protocol
Tcp/ip/udp
foundation protocol
Obex
object exchange protocol
wae
wireless application environment
Wap
wireless application protocol

12. Bluetooth profiles
Describes implementation of user
models
Defines parameter ranges of each
protocol
Decreases the risk of
interoperability problems

13. View of different sections of profiles

14. How Bluetooth works

15. Modes of
operation
piconet
connection between 2 or
more devices
each piconet is identified by
a different FHS
follows a master slave
mechanism
Scatternet
connection of different
piconets

16. Different versions of
Bluetooth
• Supports non-
• Required encrypted
mandatory channels
BD_ADDR
Bluetooth Bluetooth
1.0 & 1.0B 1.1
Bluetooth Bluetooth
2.0 1.2
• EDR • AFH, eSCO
• Low power • High
consumption transmission
speed

17. •Extended inquiry
Bluetooth response
•Secure simple pairing
2.1
Bluetooth • AMP
• High speed
3.0 transport

18. Applications of
Bluetooth
A typical Bluetooth mobile A Bluetooth USB dongle
phone headset

19. MOTOROLA –PORTABLE-
BLUETOOTH car-kit-T305 Features-
• Crisp & clear
• Smooth execution
• Fashionable & multi-
faceted
• Mini USB connector
for easy charging
• A Multi-function button

20. Advantages of
Bluetooth
Universally accepted
economical
Simplifies communication
while driving

21. Best alternative of data transfer
Instant PAN (personal area
network)
Standard protocol

22. Bluetooth v/s Wi-Fi
-->uses wireless PAN
-->simplifies discovery
& setup of Services -->uses wireless LAN
-->requires configuration
to setup shared resources

23. Bluetooth
security
As it has many benefits, also
susceptibility to denial of service
attacks—
Bluejacking
Bluesnarfing
bluebugging

24. To protect data--
Many software patches
available for older Bluetooth
phones
Turn to non-discoverable mode
when not in use
Never pair with unknown
devices or In public places

25. Disadvantages of Bluetooth
Battery mileage
Bluetooth internet

26. Thank you
for your
