Bluetooth is a wireless technology that allows personal computers, laptops, cell phones, and other electronic devices to communicate with each other over short distances of approximately 10 meters to transfer information/files from one device to another. It uses radio waves and is designed to be a secure and inexpensive way to connect and exchange information between devices wirelessly.

The following are some of the most informative Bluetooth facts from the arsenal of thousands.

Fact #1: “Bluetooth” refers to Harold Blatand, who was the 10th century Danish king who unified the Norwegians and Danes.

Fact #2: The renowned Andretti Green Racing team communicated during the race using Bluetooth devices

Fact #3: According to a research, the users of this device were expected to increase to more than 1 billion by the year 2006.

Fact #4: Analysts predict that a third of all new cars in the world will have built-in wireless Bluetooth connections.

Fact #5: Hospitals are manufacturing and deploying a large number of the latest Bluetooth medical equipment to improve patient care.

Fact #6: The latest wireless enabled devices allow you to view images on your TV screen. This can be achieved using a laptop or mobile phone via wireless connection to a media viewer.

Fact #7: Printing can be done wirelessly now! One can send files to print from a Bluetooth-enabled computer or mobile device directly to the printer. There are also small home-use printers that simply print color images using wireless input from a cell phone or computer.

Fact #8: The latest multi-point pairing Bluetooth-enabled interface allows you to connect with more than one Bluetooth device, for example, your cell phone can be connected to a Bluetooth stereo headset and your computer at the same time

Fact #9: One of the fastest growing devices in “Bluetooth hands-free” and the second largest application overall, just behind hands-free is “stereo audio”.

Fact #10: Extensive use of Bluetooth is dangerous to health. Bluetooth uses microware radio waves with a frequency range of 2.4 GHz to 2.4835 GHz and the output power of a Bluetooth radio is 100 mW, 2.5 mW, and 1 mW for Class 1 devices, Class 2 and class 3, respectively. Class 1 is almost at the same level as mobile phones, while class 2 and class 3 are much lower than class 1 and are considered less dangerous than mobile phones.

Fact #11: The future of Bluetooth is expected to have data points for broadcast channels, this will initiate the actual use of wireless connections within mobiles and enable user-based advertising models that extract information from data points, and not in the current model of limited object insertion. One of the best Bluetooth stereo headset companies that are expected to stand out in this field is Motorola and Blackberry.

Fact #12: The latest wireless communication devices can now play the role of “master” and can communicate with up to 7 devices as “slave”. This group of 8 devices (1 master + 7 slaves) is called Piconet. At any time, data can be transferred between the master and 1 slave; but the master quickly switches from slave to slave on a rotating basis to see if there are any more file transfer requests.
