Acknowledgement

Our first experience at attempting to write this book has been very

enriching. We had to consult several reference books, web sites etc

to cull out ideas & information for the book.

In writing this book, we have wished to inform you very briefly

about Bluetooth.

We have tried, as far as possible, to write it in a very simple

language so that it is acceptable to all who wish to read it. This work

has been conceived & completed within about three days, a very

short time indeed. Certain mistakes may have slipped & we would

like to apologize for them.

What is Bluetooth?

Bluetooth is actually a standard for wireless communications between

devices in apersonal area network(PAN) using radio frequency for a short

range (around 10 meters). A group of Bluetooth devices like a mobile phone,

a handheld devices etc can instantly form a network with each other as soonas they are switched on.

Bluetooth technology eliminates the

need for numerous and inconvenient

cable attachments for connecting

fixed computers, mobile phones,

handheld devices. It will enable users

to connect a wide range of computingand telecommunication devices easily

and simply, without the need to buy,

carry or connect cables. It delivers

opportunities for rapid ad hoc

connections, and possibility of

automatic connections between

devices.

Bluetooth makes wireless communication and networkingbetween devices

in a small localized area of a room or a small office as easy as switching on

the light. In Bluetooth all the connections between devices are instantaneous

and invisible and the devices can talk even if they are not in line of sight

because Bluetooth utilizes a radio-based link.

Briefly, Bluetooth technology

uses radio waves in 2.4 GHz band - therefore, no line of sight is

required

supports multipoint, not just point to point

works in a small confined area - 10 to 15 meters apart is able to support speeds of 1-2 Mbps today but will offer higher

speeds in future

chip sets are relatively inexpensive (though more expensive than

IrDA)- $10 to $20 today in large quantities - will go down in

future

has significant industry support with over 1800 members in the

industry group

Origin of Bluetooth Technology

The name Bluetooth and its logo are trademarked by the privately held

trade association named theBluetooth Special Interest Group (SIG).

Founded in September 1998, the

Bluetooth SIG is a unification of

leaders in the computing,

telecommunications, network,

industrial automation, and

automotive industries. Today,

the Bluetooth SIG is responsible

for encouraging and supporting

research and development in

Bluetooth technology.

The Bluetooth SIG includes promoter member companies Microsoft,

Ericsson, IBM, Intel, Motorola, Nokia, and Toshiba, plus thousands of

Associate and Adopter member companies.

Mission

Strengthen theBluetooth brand by empoweringSIGmembers to collaborate

and innovate, creating the preferred wireless technology to connect diverse

devices.

Bluetooth

Why is it Called Bluetooth?

The word "Bluetooth" is taken from the 10th century

Danish King Harald Bluetooth. King Bluetooth had been

influential in uniting Scandinavian Europe during an era

when the region was torn apart by wars. Scandinavia isaname applied collectively to three countries of northern

Europe- Norway, Sweden and Denmark.

The founders of the Bluetooth SIG felt the name was fitting because:-

1) Bluetooth technology was first developed inScandinavia, and

2) Bluetooth technology is able to unite different industries such as the

cell phones and computers.

Bluetooth wireless technology simplifies and combines multiple forms of

wireless communication into a single, secure, low-power, low-cost, globally

available radio frequency.

Where Did the Logo Come From?

ISAS 8


9/16

Keeping to the same origin as the Bluetooth name, the logo unites the

Germanic alphabetic characters, H, which looks similar to an asterisk and a

B, which are the initials forHarald Bluetooth. If you look close enough

you can see both inscribed in the logo.

Applications of Bluetooth Technology

Bluetooth has a tremendous potential in moving and synchronizing

information in a localized setting. Potential for Bluetooth applications is

huge, because we transact business and communicate more with people who

are close by than with those who are far away - a natural phenomenon of

human interaction. The following list represents only a small set of potential

applications - in future many more imaginative applications will come

along:-

By installing a Bluetooth

network in your office youcan do away with the

complex and tedious task of

networking between the

computing devices, yet have

the power of connected

devices. No longer would

you be bound to fixed

locations where you canconnect to the network. Each

Bluetooth device could be

connected to 200 other

devices making the

connection of every device

with every other possible.

If your digital cameras in Bluetooth enabled, you can send still or video

images from any location to any location without the hassle of connecting

your camera to the mobile phone.

Bluetooth allows us to have three way phones. At home, your phone

functions as a portable phone (fixed line charge). When you're on themove, it functions as a mobile phone (cellular charge). And when your

phone comes within range of another mobile phone with built-in

Bluetooth wireless technology it functions as a walkie-talkie (no

telephony charge).

In meetings and conferences you can transfer selected documents instantly

with selected participants, and exchange electronic business cards

automatically, without any wired connections.Connect yourwireless headsetto your mobile phone, mobile computer or

any wired connection to keep your hands free for more important tasks

when you're at the office or in your car.

Have automatic synchronization of your desktop, mobile computer,

notebook and your mobile phone. For instance, as soon as you enter your

ISAS 10

office the address list and calendar in your notebook will automatically be

updated to agree with the one in your desktop, or vice versa.

Automatic Message Delivery: Compose e-mails on your portable PC while

you're on an airplane. As soon as you've landed and switched on yourmobile phone, all messages are immediately sent.

The Bluetooth technology

connects all your officeperipherals wirelessly. Connect

your PC or notebook to

printers, scanners and faxes

without the ugly and trouble

some cable attachments.

You can increase your freedom by connecting your mouse or the

keyboard wirelessly to your computer.

Upon arriving at your home, the door automatically unlocks for you, the

entry way lights come on, and the heat is adjusted to your pre-set

preferences.

IBM researchers are working on a number of personal devices like a

WatchPadthat could be connected with other devices through Bluetooth.

The Watch Pad is very thin and contains 8MB of RAM. They are alsoworking on a version of CyberPhone called CyberPhone - that can project

data onto a small mirror. The CyberPhone can show as much information

as a smallPDA because of high resolution VGA screen.

on how many users are sharingthe service on each cell at anygiven time. A 2.5G service.

SWAP 1.2Mbps Maximum 40meters

SWAP is an industry specificationthat permits PCs, peripherals,cordless telephones and otherdevices to communicate voice anddata without the usage of cables.

IrDA vs Bluetooth

If you examine the benefits of each technology, you can see that Bluetooth

and IrDA are both critical to the marketplace. Each technology has

advantages and drawbacks and neither can meet all users' needs. Bluetooth's

ability to penetrate solid objects and its capability for maximum mobility

within the piconet allows for data exchange applications that are very

difficult or impossible with IrDA. The Omni-directional capability of

Bluetooth allows synchronization to start when the phone is brought into

range of the PC.

SWAP vs Bluetooth

Currently SWAP has more installed base compared to Bluetooth but it is

believed that Bluetooth is eventually going to prevail. Bluetooth is a

technology to connect devices without cables. SWAP is a wireless

technology optimized for the home environment. Its primary use is to

provide data networking and dial tones between devices such as PCs,

cordless phones, Web Tablets and a broadband cable or DSL modem. Both

technologies share the same frequency spectrum but do not interfere when

operating in the same space.

Which is better - Bluetooth or Wi-Fi

Wi-Fi is primarily used as an alternate to traditional cable based networks. It

has a longer range than Bluetooth, and supports faster data transfer speeds,

and so it might seem better than Bluetooth. But, in reality, Bluetooth and

ISAS 13


14/16

Wi-Fi have different purposes. Bluetooth is intended for limited data transfer

between many different types of devices, Wi-Fi is more focused on faster

data transfer between computers on a network. One of the distinctive

elements of Bluetooth is that is uses very much less power than Wi-Fi. Wi-

Fi, consumes a great deal of power, and so for any type of portable batteryoperated device, Bluetooth will allow for substantially more battery life than

would Wi-Fi.

Future of Bluetooth Technology

The Future is Bright, The Future is Bluetooth!

Because it meets the basic needs of connectivity in close range,

Bluetooth has a very bright future ahead of it. According to reports, the

Bluetooth technology is expected to be built into more than 100 million

devices, with over 670 million enabled Bluetooth devices.

Unlike infrared technology, Bluetooth is used by many different wireless

devices. Bluetooth offers exceptional quality for short range wireless,

even going through walls and obstructions. While infrared is the biggest

competitor at this time, Bluetooth beats it, proving to millions that it is

the wireless communication technology of the present day and age.

In the future, you can expect the technology behind Bluetooth to get

better. For cell phones or other forms of wireless connections, Bluetooth

is the one technology that you don't want to find yourself without.

Conclusion

Finally, Bluetooth promises to be a low cost, convenient, and simple way

of enabling your various computer devices to talk to each other. The

ISAS 14

reality has yet to match the promise, but Bluetooth is becoming more

widespread and functional every day.

Hence, it wont be wrong to say that

Bluetooth Technology is here to stay.
