The Bluetooth technology has become the standard technology for modern mobile devices. It is an indispensable part of people's daily life. But do you know how Bluetooth technology, which is so widely used, came about?
The word Bluetooth comes from the name of King Haral Bluetooth of Denmark. The king unified Denmark, which was about to split. Engineers hope Bluetooth can unify all communication transmission protocols. And it can connect all smart devices. So its name came from the king.
Ericsson was the first company to apply Bluetooth technology to equipment. Ericsson hopes to solve the incompatible data transmission between different electronic devices. For this reason Ericsson has created a series of schemes. Try to find a low power consumption and low cost wireless connection method.
In 1998, Ericsson formed a "special interest group" with IBM, Intel, Nokia and Toshiba. They invented Bluetooth technology. Thanks to the efforts of the "Special Interest Group", they created the first version of Bluetooth in the first year. After that, Bluetooth was updated and upgraded on this basis.
In the second half of 1999, Bluetooth technology was recognized by the market. With the cooperation of Microsoft, Samsung and other companies. A "Bluetooth" craze has been set off worldwide. Bluetooth has become a global technical standard.
However, Bluetooth has experienced 5 versions since its development.
Bluetooth 1.0 has been developed in three versions. At this time, the Bluetooth function is relatively limited. In the era of Bluetooth 2.0, Bluetooth can transfer files and make calls. But this version only has 2 versions of it. In the era of Bluetooth 3.0, the transmission rate has been greatly improved. The transmission rate can reach up to 24Mbps.
By 2010, Bluetooth 4.0 appeared. At this time, Bluetooth pushes low power consumption. On the basis of low power consumption. Bluetooth has increased the transmission distance to more than 100 meters. It is worth mentioning that the 2010 Apple mobile phone was the first to support Bluetooth 4.0. After that, Bluetooth was updated on the basis of 4.0. Under the condition of low power consumption, the transmission rate has been a huge improvement.
By 2016, Bluetooth 5.0 will come out. Before that, Bluetooth connection was not stable. With the application of Bluetooth 5.0, this problem has been well solved.
I believe in the near future. Bluetooth will certainly achieve the wishes of the founders. And create a universal communication transmission protocol. That would be convenient.
