What is Bluetooth® technology?
Bluetooth® technology is the name of the trademark for the wireless network protocol. In most cases, Bluetooth® technology appears in wireless networks of personal areas (PAN), which are networks that combine personal electronic devices over short distance. Bluetooth® basically uses wireless communication with a short range to replace the cables needed to connect the device. Bluetooth® automatically connects to other devices as they move within range, so Bluetooth® technology is easy to use for anyone, regardless of their technology experience. The device that works well inside the Bluetooth® pan includes headset for hands-free mobile phone, wireless mouse or keyboard for computer and video game consoles.
created in 1998, Bluetooth® Special Heated Group (SIG) oversees the development and changes of Bluetooth® protocols. Engineers for the Swedish company Ericsson Mobile Platforms have developed Bluetooth® technology in 1994. Soon SpeeBluetooth® CHIFICATIONs did not work well, but after a stabilized version it appeared in 2002, products began to appear on the market.
up to eight Bluetooth® devices, including mobile and stationary devices, can be connected at the same time. Bluetooth® technology has advantages over other types of wireless protocols because it is cheap to use and because it does not require a line of vision between devices as well as infrared. However, Bluetooth® cannot correspond to the distance or speed of some other wireless protocols such as WiFi.
Wireless technology for Bluetooth® is called Spectrum Frequency Hopping Spectrum. In principle, frequency jumping involves dividing the data to be sent via the pan into small pieces. Bluetooth® technology then allows pieces to travel through one of the 79 different wireless frequencies. By using multiple frequencies, a pelvis using Bluetoot technologyH® can send data in the most effective way and can avoid temporary interference from other devices at some frequencies. Mr. Bluetooth® works through the microwave frequency width of 2.4 GHz band, which is unlicensed and available for use of any device.
Concerns' security prevailed with Bluetooth® technology in its early years, so the user data was sent via the pan in the risk of being stolen. Most of the initial security problems were related to the use of Bluetooth® hardware rather than the protocols themselves. The Bluetooth® virus originally appeared in 2004. Most of the Bluetooth security fears have been resolved in recent years, although there are still various problems from time to time.
founders Bluetooth® named this technology after the Danish and Norwegian king of the 10th century Harald Bluetooth. The king reportedly tried to unify warring tribes in Denmark and Norwěy. Bluetooth & Reg founders imagined their technology unitedThe difficult use of wireless technologies, which made it easier for different types of data to replace data.
