Bluetooth’s pronunciation is ['blu:tu:θ] in British English, and ['blu:tu:θ] in American English.

Literally it means blue tooth。 In reality, bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2。4 to 2。485 GHz) from fixed and mobile devices, and building personal area networks (PANs)。 Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables。 It could be used in wireless information transmission among mobile phone, PDA, wireless headset, laptop and some other related peripherals。 Bluetooth technology not only simplifies communication between mobile communication terminal devices,

But also simplifies communication between devices and Internet. Based on this technology, data transmission becomes more agile and efficient.

What does Bluetooth in mobile phone mean:

Bluetooth headset and Bluetooth speakers is the most common bluetooth products in our daily life. So most Bluetooth enthusiast start getting the conception and meaning of Bluetooth from bluetooth headset. There are different bluetooth versions including 2.0, 3.0, 4.0, 4.1 and so on for bluetooth headset. The different bluetooth profiles result in differences in function and transmission among different bluetooth versions.

Bluetooth’s Development History

Bluetooth is a technology standard for near-spaced wireless digital communications which is  proposed by Toshiba, Ericsson, IBM, Intel and Nokia in May 1998. The goal is to complete the maximum data transmission with speed of 1Mb / s (useful transmission speed of 721kb / s), the maximum transmission interval of 10 meters, users could use the 2.4GHz ISM (industrial, scientific, medical) frequency band directly without any requests. Based on 79 channels with a bandwidth of 1MHz which is established on the ISM frequency band, they could complete the radio transceiver by hobbing method of spectrum diffusion skills and switching the frequency 1600 times per second,

    In fact, Bluetooth is an open standard for wireless data and voice transmission. It combines various communication devices, computers and their terminal devices, various digital data systems, and even home appliances. Its transmission distance is 10cm ~ 10m, if increase the power or add some peripherals can reach 100m transmission interval. In a word, Bluetooth is a low-cost, high-capacity, short-interval wireless communication standard. Bluetooth notebook is laptop with Bluetooth wireless communication function. There is a little history of the word “Bluetooth”. In the 10th century AD, the Nordic princes vied for supremacy, the Danish king came forward, in his tireless efforts, the bloody battle was prevented. All the princes sat down to negotiate. After the communication, princes agreed to let bygones be bygones. The Danish king was known as Bluetooth king, because he liked to eat blue plum, and then his teeth are dyed blue. So Bluetooth has become a synonym for communication. A thousand years later, when the new wireless communication standards established, we use Bluetooth to name it.
