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.

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

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

INFRARED(CONTD..)-Infrared technology has drawbacks it does have several advantagesincluding:

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.

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.

BLUETOOTH1.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.

Bluetooth

One of the first modules (Ericsson).

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

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.

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.

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.

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

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 .

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.

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.

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.

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.

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.

APPLICATIONS

– Signal can carry data

– Information can be shared by users

– Electronic business cards

CONCLUSION & FUTURE DIRECTION

Just in time for the first year ofthe real new millennium i.e., 2001-2100. The P802.15Working Group is paving the way for Personal AreaNetwork Standards that will be - Networking theWorld TM.

Wireless personal area networks will proliferate earlyin the next millennium and the IEEE P802.15 WorkingGroup for Wireless Personal Area Networks(WPAN’s) is providing the leadership in the IEEE 802Standards Committees to establish open standards forthese WPAN’s
