Bluetooth PresentationMatt Susi – Damian Orzel
What is Bluetooth?• Short-range communications technology• Intended to replace cables connecting portable
and/or fixed devices• Still able to maintain a high level of security• Defines uniform structure for wide range of devices
to connect and communicate• Key features are– Robustness, low power, and cost
What is Bluetooth? Cont’d
• Intended to create a PAN• Operating range of 10 metres, with optional 100
metre mode.• Transmission power of 1 mW• Operates in free ISM band [2.4000 – 2.4835 GHz]
Basic Uses• Cable replacement• Voice and Data access points• Ad-hoc/temporary networking– Up to 8 devices can be networked at a time
History of Bluetooth?• The name “Bluetooth” comes from an english
translation of Harald Blåtand, a tenth-century king of Denmark
• United dissonant Danish tribes into an unified kingdom
• The relation of names is because the implication of Bluetooth technology is that it unites communication protocols into one universal standard.
The start of Bluetooth?• Ericsson Mobile Communication• Bluetooth Special Interest Group (SIG)– Ericsson, Toshiba, Intel, Nokia, & IBM
Timeline- The Bluetooth Special Interest Group (SIG) is formed with five companies.- The Bluetooth SIG welcomes its 400th member by the end of the year.- The name Bluetooth is officially adopted.
- The Bluetooth 1.0 Specification is released.- The Bluetooth SIG hosts the first UnPlugFest for member engineers.
- First mobile phone.- First PC Card.- Prototype mouse and laptop demonstrated at CeBIT 2000.- First Headset.
Timeline- First printer.- First laptop.- First hands-free car kit.- First hands-free car kit with speech recognition.
- First keyboard and mouse combo.- First GPS receiver.- Bluetooth wireless qualified products now number 500.- First digital camera.
- First MP3 player.- Bluetooth Core Specification Version 1.2 adopted by the Bluetooth SIG.- Shipment of Bluetooth enabled products hits rate of 1 million per week.- First FDA-approved medical system.
Timeline- The Bluetooth SIG adopts Core Specification Version 2.0 + Enhanced Data Rate (EDR).- Bluetooth technology reaches an installed base of 250 million devices.- Product-shipment rate surpasses 3 million per week.- First stereo headphones.
- Product shipments soar to 5 million chipsets per week.- The Bluetooth SIG welcomes its 4,000th member.- First Sunglasses.
- First watch.- First picture frame.- Bluetooth wireless reaches an installed base of 1 billion devices.- Bluetooth enabled devices ship at a rate of 10 million per week.- First alarm-clock radio.
Timeline- First television.- The Bluetooth SIG welcomes its 8,000th member.- Bluetooth SIG Executive Director, Michael Foley, wins Telematics Leadership Award.
- 2008 marks Bluetooth technology’s 10 year anniversary - no other wireless technology has grown to be shipping nearly 2 Billion products in 10 years.- The Bluetooth SIG welcomes its 10,000th member.
- The Bluetooth SIG adopts Core Specification Version 3.0 + HS making Bluetooth high speed technology a reality- The Bluetooth SIG welcomes its 12,000th member
Applications of Bluetooth• Telephones• Headsets• Computers• Computer accessories• LAN peripherals• Multimedia Devices
How does Bluetooth work?• When device is put in discoverable mode, each
device only knows about itself.
How does Bluetooth work? Cont’d
• INQUIRY identifies who else is in the range
How does Bluetooth work? Cont’d
• PAGING creates a link between a device
How does Bluetooth work? Cont’d
• EXPANDING creates link between following devices
Advantages vs. DisadvantagesAdvantages Disadvantages
• Offers a great deal of possibilities • Data rate of only 1 MBps.
• Freedom from cables • Open to interception and attack
• Accuracy in Local Area Networks (LAN) • Battery use increased on devices
• Operating range of up to 100 metres • Cannot work in a long distance environment
• Low power and low processing
• Applications are virtually endless
• Inexpensive
• Does not need to be configured
•Security features of authentication, authorization, and encryption
Costs of Bluetooth• Uses low-cost transceiver microchips• Estimated to cost around $4 to manufacture• Operates on unlicensed radio spectrum– No charge in communication between devices
• Only cost associated is for the actual product that is enabled with Bluetooth
Human Impact• Common concern is that carrier waves inhabit the same
band as that of microwave ovens• Transmitting power is much too weak to affect humans• Exposure to Bluetooth radio frequencies does not result in
heating of the body• However, long exposure to radio fields can result in some
people no longer being able to tolerate the waves• This is where the future development for Bluetooth will
head, in making sure this form of communication is safe.
Limitations/Future • Security – data transmission is not completely secure• BT is relatively new, it is still currently being
developed, expanded, and improved.• The next stage in the development of Bluetooth is in
creating more applications and devices of the technology while maintaining efficiency and low-cost
Dealing with current concerns
• Current concern of using electronic devices while driving
• New law in Ontario prohibits the use of talking/texting on your cell phone while driving.
• Bluetooth is the solution to this safety concern• This added law is sparking an increase in sales of
electronic products, assisting the downturned economy’s in a regrowth.
Leading the way• The free market has been, and will be leading the way
for the future of Bluetooth.• Most applications of BT have been made by people
who have put their ideas together into a single form of communication
• Canada’s role in developing Bluetooth is in the government investing money in production of Bluetooth devices.– Despite the minor role, Canada has made laws that cause an
increased awareness of Bluetooth and as a result, an increase in sales and future possibilities.
Presence in our field• Bluetooth technology will be continuously expanding
and our market will deal with producing certain BT products for the future
• We may also encounter Bluetooth technology in our workplace in the application aspect, where we will be using this technology to communicate with co-workers, bosses, and firms in a faster and more efficient way
B-Tech Preparation• Our program will allow us to gain knowledge in
producing these Bluetooth devices• Application of sciences and programming language, as
well as critical thinking where we must think of new ideas to improve/create products that will be present in common society’s future.
• Our hands-on skills will allow us to deal with a BT product, analyze it, and improve on the deficiencies and problems that are present with a certain device.
Misconceptions of Bluetooth• The name is in no way related to a person that had
blue teeth• BT is not a short-range technology• BT can expose sensitive data• Devices that have “Discoverable Mode” turned OFF,
can still be located
Why Bluetooth?• Expansive growth in the last few years• Recent driving laws will cause an increased need for
Bluetooth technology, and we would like everyone to know what it exactly is
• Relates to our Bachelor of Technology program, as Bluetooth technology is used in all three fields, and the material we are learning will apply directly in the production of this relatively new form of communication
• It is the future of communication, as the amount of Bluetooth application possibilities is endless
