- adopted protocols

21. Core System Protocols

22. Core System Protocols
− Radio (RF) protocol : Specifies details of the air interface, the use of frequency hopping,
modulation scheme, and transmit power.
− Baseband protocol : Concerned with connection establishment within a Piconet,
addressing, packet format, timing, and power control.
− Link Manager protocol (LMP) : Responsible for link setup between Bluetooth devices
and ongoing link management.
− Logical link control and adaptation protocol (L2CAP).
L2CAP provides both connectionless and connection-oriented services.
− Service discovery protocol (SDP) : Device information, services, and the characteristics
of the services can be queried to enable the establishment of a connection between two
or more Bluetooth devices.

23. Additional Protocols

24. Additional Protocols
−RF COMM : It provides connections to multiple devices by relying on L2CAP to
handle multiplexing over single connection
−Wireless access protocol (WAP): It supports the limited display size and
resolution typically found on mobile devices by providing special formats for
Web pages
−Object exchange protocol (OBEX): OBEX is a protocol designed to allow a
variety of devices to exchange data simply and spontaneously.
−Telephony control protocol : Bluetooth's Telephony Control protocol
−Specification (TCS) defines how telephone calls should be sent across a
Bluetooth link.
−Point-to-point protocol (PPP): The point-to-point protocol is an Internet
standard protocol for transporting IP datagram over a pointto-point link.

25. Bluetooth Profiles

26. Bluetooth Profiles

Bluetooth profiles
‘‘3lshan td5Ol dyrtna, m7tag visa w t2Shera’’
- Each profile specification contains information on the following
Topics:
−Dependencies on other profiles
−Suggested user interface formats
−Specific parts of the Bluetooth protocol stack used by the profile. To perform its
task, each profile uses particular options and parameters at each layer of the
stack .

27. Health Concerns

28. Health Concerns
- Zy m Olna mn shwya
- The penetration depth is about 3 cm at 2450MHz which means that the
absorption is very superficial

29. Applications of Bluetooth

30. Applications of Bluetooth
- Hands free headset. This was one of the earliest applications to become popular.
- Wireless communication with pc input and output devices, the most common being the mouse,
keyboard and printer.
- Transfer of files, contact details, calendar appointments, and reminders between devices with
obex.
- In 2004 released cars like toyota prius & lexus ls 430 have hands free call system.
- Sending small advertisements from bluetooth-enabled advertising hoardings to other,
discoverable, Bluetooth devices.
- In game consoles like Sony's PlayStation 3.
- In Real-time location systems (RTLS).
- Digital Pulse Oximetry System Toshiba Washer & Dryer.
- Personal security application on mobile phones for prevention of theft or loss of items.
