12 amazing Bluetooth facts
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 about 10 meters to transfer information / files from one device to another. It uses radio waves and is designed to be a safe and inexpensive way to connect and exchange information between devices wirelessly.
Below are some of the most informative Bluetooth facts from the arsenal of thousands.
Fact # 1: “Bluetooth” refers to Harold Blatand, who was the Danish king of the 10th century and unified Norwegians and Danes.
Fact # 2: The renowned Andretti Green Racing team communicated during the race using Bluetooth devices
Fact # 3: According to research, users of this device were expected to increase more than 1 billion by 2006.
Fact # 4: Analysts predict that a third of all new cars in the world will have built-in Bluetooth wireless connections.
Fact # 5: Hospitals are manufacturing and implementing a large number of the latest Bluetooth medical equipment to improve patient care.
Fact # 6: The latest wireless communication enabled devices allow you to view images on your television screen. This can be accomplished using a laptop or mobile phone via a wireless connection to a media viewer.
Fact # 7: Printing can be done wirelessly now! Files for printing from a Bluetooth enabled computer or mobile device can be sent directly to the printer. There are also small home-use printers that simply print color images by taking wireless input from the cell phone or computer.
Fact # 8: The latest multipoint pairing Bluetooth-enabled interface allows you to connect with more than one Bluetooth device, for example, your cell phone can connect to a stereo Bluetooth headset and your computer at the same time
Fact # 9: One of the fastest growing “Bluetooth hands-free” devices and the second-largest general application, right behind hands-free, is “stereo audio.”
Fact # 10: Extensive use of Bluetooth is dangerous to health. Blue tooth uses microwave radio waves with a frequency range of 2.4 GHz to 2.4835 GHz and the output power of a Blue tooth radio is 100 mW, 2.5 mW and 1 mW for class 1 devices , class 2 and class 3, respectively. Class 1 is almost on 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: Future of Blue tooth is expected to have information points for transmission channels, this will initiate the real use of wireless connections within mobiles and allow user-based advertising models that extract information from information points, and not based In the current limited object push model. One of the best Bluetooth stereo headphone companies expected to excel in this field is Motorola and Blackberry.
Fact # 12: The latest wireless communication devices can now play a “master” role and can communicate with up to 7 devices as “slaves”. 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 rotational basis to see if there are more file transfer requests.
