Q: What is Bluetooth?
A: Bluetooth is the name for a short-range, digital, radio-frequency (RF) technology that transmits voice and data over short distances between compatible electronic devices. The effective range of Bluetooth-device transmission is 33 feet (10 meters).
Q: Why is the technology called Bluetooth?
A: When Bluetooth wireless technology was created, its purpose was to unite elements of the telecommunications and computer industries. In that spirit of unification, the name refers to Danish King Harald “Bluetooth” Blatand, who united Denmark and Norway. The king’s nickname comes from his almost constant consumption of his favorite fruit, blueberries.
Q: How is Bluetooth used?
A: Basically, Bluetooth technology provides secure communication of audio signals and data from one device to another without using cables. Different Bluetooth applications have the ability to connect various devices to one another — for example, computers to their peripherals, telephones to ear-level receivers, stereo amplifiers to speakers, personal digital assistants to computers — in a growing community of electronic gadgets.
Q: Are different brands of Bluetooth products compatible?
A: Yes. Adherence to the Bluetooth design standards guarantees compatibility across manufacturers. Indeed, this compatibility is the very motivation behind Bluetooth’s development. Keep in mind that Bluetooth is not a product; it should be thought of as “an enabling technology.”
Q: How secure is a Bluetooth network?
A: Bluetooth is extremely secure because Bluetooth devices combine the use of a Pass Key and a specific address to identify other Bluetooth devices. Encryption can also be used to supplement the level of Bluetooth security.
Q: How do I know if my phone is Bluetooth compatible?
A: That information should be in your owner’s manual. If you don’t have your owner’s manual, contact your cell phone provider or look for that information on the provider’s Web site.
Q: What do the terms pairing and connecting mean?
A: Pairing is the process by which two Bluetooth enabled devices see one another and recognize that they have the ability to share data. Connecting is the process by which the two devices are linked and made ready to share information. It is analogous to plugging in a cable to connect the two. These processes take less than a minute, and their details are dictated by the particular cell phone you use.
Frequently Used Terms
Bluetooth: A wireless protocol defining the exchange of data between compatible devices over short distances up to 33 feet.
Connectable: A Bluetooth enabled device in range that will respond to another device and set up a connection.
Connected: A Bluetooth enabled device is within range and communicating over the Bluetooth wireless link. The LCD display will show the name of the device.
Discoverable: When a Bluetooth enabled device is “discoverable,” other Bluetooth devices can detect, pair, or connect to it. When the Quattro 4.0 is discoverable by your cell phone you will see “Quattro 4.0” in the list of Bluetooth devices in your cellphone’s Bluetooth menu.
Pairing: The process of creating a persistent link between two Bluetooth devices. This only occurs once; future connections between the devices are authenticated automatically.
Multipoint: Multipoint is a new development in Bluetooth technology that allows your Bluetooth Headset to be connected to two Bluetooth devices at the same time. When a call comes in, the Bluetooth headset knows which device is ringing and will connect to the right one automatically. EDR: EDR is an optional part of the Bluetooth specification that provides a faster data rate (speed) and in some cases improved battery life.
A2DP: The abbreviation for Advance Audio Distribution Profile. A2DP technology is a new music revolution allowing you to send CD quality stereo music from one device to another without wires. A2DP is stereo music sent over Bluetooth without the hassle of plugging cables.
Profile: A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices. In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles necessary to use the desired services.
