8. INTRODUCTION
 Bluetooth Wireless Technology (BWT) was developed in
1994 at Ericsson in Sweden.
 It is named for Harald Blaatand.
 Bluetooth-Wireless and Automatic technology simplifying
art of communication.
 Frequency used is 2.45 GHz, same used in ISM devices
 Purpose – Originally it was build to eliminate the need for
cable connections between PDAs and notebook PCs. 8

9. BLUETOOTH SPECIFICATION
 Bluetooth-Wireless technology providing link
between mobile and electronic devices.
 It operates on 2.45 GHz radio signals using
frequency hopping spread spectrum.
 Technology of Bluetooth concentrates on short
range of communication.

10. BLUETOOTH SPECIFICATION
•Standard: IEEE 802.15
•ISM Band Frequency: 2.4 GHz
•Range: 10 – 100 meters
•Channel Bandwidth: 1 Mbps
•Maximum Asymmetric Data Transfer Rate: 721 Kbps
10

11. TYPES OF BLUETOOTH WIRELESS TECHNOLOGY
Depending on the power consumption and range of
the device, there are 3 Bluetooth Classes as:
•Class 1: Max Power – 100mW ;
Range – 100 m
•Class 2: Max Power – 2.5mW ;
Range – 10 m
•Class 3: Max Power – 1mW ;
Range – 1 m

12. WHY THE NAME BLUETOOTH?
The name was adopted as a tribute to the
tenth-century king Harald Blaatand .
Harald liked to eat blueberries,which gave his
teeth the coloration that lead to the nickname
"Bluetooth.“
12

13. BLUETOOTH BASICS
 Bluetooth is low powered and low cost.
 All the devices follow a uniform structure
 Devices Connect through network called Pico nets.
 Strength lies in handling data and video
transmission simultaneously.
13

14. HOW BLUETOOTH WORKS?
 They normally operate at 2.45GHZ in license free
globally available ISM radio band.
 Advantage-worldwide availability and compatibility.
 Disadvantage- devices must share the bandwidth
with other RF emitters including automobile security
systems, noise sources such as Microwaves
 Solution- Frequency Hopping Spread Spectrum.
14

16. BLUETOOTH SOFTWARE
 Bluetooth software can be installed and used on
Bluetooth capable devices.
 There exists different software for different devices
like PDA , personal computer.
 Enables the device to use technology at its fullest.
 Best example is Bluesoleil.
16

17. BLUETOOTH SOFTWARE
 Bluesoleil can be installed on
personal computer or on
 personal digital assistant also
 On a PC, it provides a lot of
Extra wireless features.
 It also has a graphical user
interface (GUI).
 On a PDA, provides basic
Bluetooth profiles such as
headset and hands free profile
personal networking (PAN)
profile

18. FUTURE OF BLUETOOTH
•BROADCAST CHANNELS:Adoption of Bluetooth
into mobile phones and enable advertising models
based on users pulling information from the
information points.
•TOPOLOGY MANAGEMENT:Automatic
configuration of piconet topologies in scatternet
situations.

22. ZIGBEE
PART II

24. WHAT IS ZIGBEE?
 ZigBee is a new wireless technology
 Technological Standard Created for Control and Sensor
Networks
 Based on the IEEE 802.15.4 Standard
 Created by the ZigBee Alliance
 Philips,Motorola,Intel,HP are all members of the
alliance.
24

25. ZIGBEE
 Designed for low power consumption allowing batteries
to essentially last for ever
 ZigBee makes possible completely networked homes
where all devices are able to communicate and be
controlled by a single unit
 It provides network,security and application support
services operating on the top of IEEE
25

26. ARCHITECTURE
 Layered architecture
 These layers facilitate the features that make
ZigBee very attractive:
low cost
 easy implementation
 reliable data transfer
 short-range operations
 very low power consumption
adequate security features
26

27. ARCHITECTURE
Layers
1.Network and Application Support layer
2.Physical (PHY) layer
3.Media access control (MAC) layer
27

28. ZIGBEE DEVICE TYPES
 There are three different ZigBee device types that
operate on the layers in any self-organizing
application network
1. Zigbee Coordinator node
2. Full Function Device (FFD)
3. Reduced Function Device(RFD)
28

29. 1.ZIGBEE COORDINATOR NODE
 It is the root of network tree and a bridge to other
network
 Able to store information about the network
 Only one ZCN for a network
 It act as a repository for other security keys
29

30. 2.THE FULL FUNCTION DEVICE
 An intermediatory router transmitting data from
other devices
 Needs lesser memory than Zigbee coordinator
node
 Lesser manufacturing cost
 Can operate on all topologies
 Also act as a coordinator
30

31. 3.THE REDUCED FUNCTION DEVICE
 Device capable of talking in the network
 It cannot relay data from other devices
 Less memory
 Cheaper than FFD
 It talks only to the n/w coordinator
31

33. The ZigBee Alliance is an association of
companies working together to enable
reliable, cost-effective, low-power,
wirelessly networked, monitoring and
control products based on an open
global standard.

 1 Mbps over the air, ~700 kbps best case data transfer
 File transfer, streaming telecom audio
 Point to multipoint networking
 ZigBee targets low data rate, low duty cycle
 250 kbps over the air, 60-115 kbps typical data transfer
 Long battery life (weeks to months)
 More sophisticated networking 37

38. ZIGBEE VS OTHER WIRELESS

39. CHARACTERISTICS
 Low power consumption with battery life ranging from
months to years
 High density of nodes per network
 Low cost
 Simple implementation

41. IEEE 802.15.4
Zigbee is set of high level communication protocols based
upon the specification produced by 802.15.4 - standard for
wireless personal area networks (WPANs)
41

42. IEEE 802.15.4 CHARACTERISTICS
 Maximum data rates allowed for each of these
frequency bands are fixed as 250 kbps @2.4 GHz, 40
kbps @ 915 MHz, and 20 kbps @868 MHz
 Channel access using Carrier Sense Multiple Access
with Collision Avoidance (CSMA - CA)
 Addressing space of up to 64 bit IEEE address
devices, 65,535 networks
42

43. APPLICATIONS
 The ZigBee Alliance targets applications Across
consumer, commercial, industrial and government
markets worldwide
 Home networking
 Industrial control and management

45. CONCLUSION
In future all devices and their controls will be based
on this standard.
Since Wireless personal Area Networking applies
not only to household devices, but also to
individualized office automation applications,
ZigBee is here to stay. It is more than likely the
basis of future home-networking solutions 
