Bluetooth is a short-range wireless technology that allows various electronic devices such as computers, phones, and headphones to connect and communicate without wires. It operates in the unlicensed 2.4 GHz radio band and can connect up to 8 devices within a range of about 10 meters. Bluetooth was developed in 1994 by Ericsson to simplify connections between devices by replacing cables. It has since become widely adopted and integrated into many consumer electronic products.

2. What is Bluetooth?Short-range communications technologyIntended to replace cables connecting portable and/or fixed devicesStill able to maintain a high level of securityDefines uniform structure for wide range of devices to connect and communicateKey features areRobustness, low power, and cost

3. What is Bluetooth? Cont’dIntended to create a PANOperating range of 10 metres, with optional 100 metre mode.Transmission power of 1 mWOperates in free ISM band [2.4000 – 2.4835 GHz]

4. Basic UsesCable replacementVoice and Data access pointsAd-hoc/temporary networkingUp to 8 devices can be networked at a time

5. History of Bluetooth?The name “Bluetooth” comes from an english translation of HaraldBlåtand, a tenth-century king of DenmarkUnited dissonant Danish tribes into an unified kingdomThe relation of names is because the implication of Bluetooth technology is that it unites communication protocols into one universal standard.

16. Advantages vs. Disadvantages

17. Costs of BluetoothUses low-cost transceiver microchipsEstimated to cost around $4 to manufactureOperates on unlicensed radio spectrumNo charge in communication between devicesOnly cost associated is for the actual product that is enabled with BluetoothHuman ImpactCommon concern is that carrier waves inhabit the same band as that of microwave ovensTransmitting power is much too weak to affect humansExposure to Bluetooth radio frequencies does not result in heating of the bodyHowever, long exposure to radio fields can result in some people no longer being able to tolerate the wavesThis is where the future development for Bluetooth will head, in making sure this form of communication is safe.

18. Limitations/Future Security – data transmission is not completely secureBT 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

19. Dealing with current concernsCurrent concern of using electronic devices while drivingNew law in Ontario prohibits the use of talking/texting on your cell phone while driving.Bluetooth is the solution to this safety concernThis added law is sparking an increase in sales of electronic products, assisting the downturned economy’s in a regrowth.

20. Leading the wayThe 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 communicationCanada’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.

21. Presence in our fieldBluetooth technology will be continuously expanding and our market will deal with producing certain BT products for the futureWe 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

22. B-Tech PreparationOur program will allow us to gain knowledge in producing these Bluetooth devicesApplication 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.

23. Misconceptions of BluetoothThe name is in no way related to a person that had blue teethBT is not a short-range technologyBT can expose sensitive dataDevices that have “Discoverable Mode” turned OFF, can still be located

24. Why Bluetooth?Expansive growth in the last few yearsRecent driving laws will cause an increased need for Bluetooth technology, and we would like everyone to know what it exactly isRelates 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 communicationIt is the future of communication, as the amount of Bluetooth application possibilities is endless
