3. INTRODUCTION
• A computer network is a system for communicating
between two or more computers and associated devices
• A popular example of a computer network is the internet,
which allows millions of users to share information
• Computer networks can be classified according to their
size:
– Personal area network (PAN)
– Local area network (LAN)
– Metropolitan area network (MAN)
– Wide area network (WAN)
•A PAN is a network that is used for communicating among
computers and computer devices (including telephones) in close
proximity of around a few meters within a room.
4. What is PAN?
Personal Area Network
. A personal area network (PAN) could be thought of as the interconnection of devices within
the range of an individual person and nowadays typically uses wireless technology (WPAN).
. It can be used for communicating between the devices themselves, or for connecting to a larger
network such as the internet , Devices are normally within 1-10m
•PAN’s CAN BE TWO TYPES-
• WIRED
• WIRELESS

10. Types of Wireless Personal Area Networks are
currently available?
1.INFRARED
2.HomeRF (home radio frequency)
3.BLUETOOTH
INFRARED:1.Infrared technology is probably the best known and
most mature WPAN technology. Communication takes
place between two devices that are in line of site of
each other.
2.This means that if an object obstructs the
infrared path between the two devices the network
link will fail. Thus, infrared technology is unsuitable
for WPAN use unless both devices can be placed
close together and kept relatively static
11. INFRARED(CONTD..)
-Infrared technology has drawbacks it does have several advantages
including:
1.A relatively high data rate when compared to other WPAN
technologies (currently up to 4Mbps)
2.Being free from interference from radio technologies
3.Being cheap to install in devices
4.A lack of complicated addressing issues between devices
Infrared technology can be found in a range of devices including
PDAs, mobile phones, laptops and remote controls.
12. HomeRF (home radio frequency)
HomeRF technology can still be found in such devices as
keyboards, future development work on HomeRF products has
now stopped and thus it is unlikely that devices with this technology
will feature strongly in future WPANs.
BLUETOOTH
1.Bluetooth is a short range wireless
technology endorsed by major technology
companies and has now been accepted as
the IEEE 802.15.1 standard.
2.Bluetooth utilises the 2.45GHz radio
band and supports data rates of up to
780Kbps.
14. BLUETOOTH(CONTD..)
3. This technology was originally designed for short range wireless
connectivity between two devices replacing traditional wired solutions
and unlike infrared there doesn't have to be a clear line of sight
between Bluetooth devices.
4. Options include using Bluetooth in the same way as WLANs are used
over a distance of up to 100 metres (although data rates of Bluetooth
are significantly lower (~780Kbps)).
5.All Bluetooth devices have a minimum set of functionality that will
allow them to locate another Bluetooth device
15. 4.WPAN devices are there?
There are many devices currently on the market that have a
WPAN technology built in to them. PDAs, mobile phones and
laptops can all be bought that have inbuilt WPAN technology
(usually Bluetooth or Infra-red).
5. Implementation issues for PAN?
It is important to be clear and realistic about the tasks and
types of use for which WPANs are appropriate and those for
which they are not.
16. How easy is it to establish a PAN network?
In the case of infrared, sending data from one device to the next
usually requires the user to set the device to allow incoming infrared
beam requests.
Once another device comes in range of a network and attempts
to send data a network is established.
In the case of Bluetooth, a device is set so that it actively tries to
discover other Bluetooth devices or is set to a mode that allows
itself to be discovered by all other Bluetooth devices or chosen
devices (this depends on the manufacturer of the device though).
A network is established when a device that is seeking
another device locates another Bluetooth device.
17. In both WPAN technologies, once a network is established a
receiving device normally has to wait for the user to actively
accept incoming data before it can be viewed or stored.
Using WPAN features to connect a device to the internet:
This is another common use for WPAN especially amongst
those people who spend time away from their fixed network
connection point. A connection to the internet is made by a
WPAN device (normally a mobile phone) via GSM/GPRS.
A WPAN is then formed from this device to another
Bluetooth enabled device such as a laptop. In this way the user
can use the laptop to wirelessly gain access to the internet.
18. 6. What are the standards issues relating to WPANs
One of the main standards bodies for WPAN technologies is the IEEE
(Institute of Electrical and Electronic Engineers). This is the same body
that governs the 802.11 (Wi-Fi) standards. WPAN technology standards
governed by the IEEE come under the 802.15 umbrella.
IEEE 802.15.1
IEEE 802.15.2
IEEE 802.15.3
IEEE 802.15.3a
IEEE 802.15.4
19. 7.NEW AND LATEST RESEACH PAPER ON WPAN.
A new generation of Wireless Personal Area Networks (WPANs) is intended for high
data rate and multimedia applications. The MBOA WPAN system, which is
standardized by the Multiband OFDM Alliance (MBOA), is able to provide data rates
up to 480Mb/s over a short distance based on the Ultra-Wideband (UWB) frequency
band as well as support the Quality of Service (QoS) for both synchronous and
asynchronous traffic.
The MBOA system has been considered as one of the most potential solutions for
the Physical layer (PHY) and Medium Access Control (MAC) of the next generation of
WPANs. In addition to the high PHY data rates, the MBOA system provides also high
MAC efficiency, especially for the high speed burst transmission and frames of small
size .

21. 8. Differences Between WPANs and WLANs.
The goal for WPANs is replacing wires between objects
that are close to each other and have a short range.
Wireless Local Area Networks (WLANs) are used as wireless
replacements for traditional Ethernet type networks and
currently have a greater data rate and range than most
WPANs.
WLANs are often associated with portable devices such
as laptops this type of network is often not considered to
be as portable as WPANs.
22. Ideally, WPANs should complement WLANs but there is
inevitably some overlap in the technologies.
For example, Bluetooth devices can be purchased that
can form a WPAN with other devices that are located within
a few metres or connected to a WLAN from distances up to
100m.
23. 9. Where and how can WPANs be used in education?
One of the common features of WPANs is that they aim to make
creating a network easy to do. Thus, WPANs often mean immediate
deployment of a dynamic network.
Examples of how WPANs can be useful within an educational
setting include:
•Exchanging information directly between PDAs
•Synchronising files between a desktop PC and a PDA
•Connecting a keyboard or mouse wirelessly to a desktop
computer
•Printing a document using a WPAN enabled printer and laptop
•Connecting a WPAN enabled mobile phone to a laptop to use the
Internet via GSM/GPRS whilst doing fieldwork.
•Dynamic network creation for group work using WPAN enabled
devices.
24. 11.Advantages and Disadvantages & APPLICATIONS.
WPANs have a number of key
advantages when used in an educational
environment:
•Dynamic network setup
•Usually quick and relatively simple to set up.
•WPAN enabled devices are usually portable.
•Typically need less technical skills to deploy
than LANs or WLANs.
25. General (rather than specific to educational use)
disadvantages of WPANs include:
•Typically have a limited range.
•Currently limited to relatively slow data rates when compared with
WLAN technologies.
•Compatibility and interoperability issues; WPAN technologies are not
usually compatible with each other. Some WPAN technologies such as
Bluetooth are known to have had interoperability issues between
devices from different manufacturers
•Devices with inbuilt WPAN technologies can be
considerably more expensive than devices without WPAN
technologies.
26. APPLICATIONS
In Medical & Hospitals
In railways and Airports station
In Organization and Companies
In Schools and College Education
In Defence And Military
In Home, Office & Small Industries

28. WPAN Future
• Human body carries electrical signal
– Signal is low and unnoticeable by users
– Signal can carry data
– Information can be shared by users
– Electronic business cards
29. CONCLUSION & FUTURE DIRECTION
Just in time for the first year of
the real new millennium i.e., 2001-2100. The P802.15
Working Group is paving the way for Personal Area
Network Standards that will be - Networking the
World TM.
Wireless personal area networks will proliferate early
in the next millennium and the IEEE P802.15 Working
Group for Wireless Personal Area Networks
(WPAN’s) is providing the leadership in the IEEE 802
Standards Committees to establish open standards for
these WPAN’s
