Bluetooth = wireless transmission line

Bluetooth technology is an open global specification for wireless data and voice communication. Its essence is to establish a universal radio air interface for the communication environment between fixed devices or mobile devices, and further combine communication technology with computer technology, so that various 3C devices can communicate or operate with each other in a short distance without wires or cables. Simply put, Bluetooth technology is a technology that uses low-power radio to transmit data between various 3C devices. Its greatest advantage is that it can replace all kinds of messy transmission lines.

No longer bound by transmission lines.

The length of traditional transmission lines is limited, and there are certain requirements for the location of equipment. If the transmission line is too short, the equipment can't be too far away from the computer. The transmission line is too long, and it has to go around east and west, which is troublesome and unsightly. After switching to Bluetooth wireless transmission, you can break through the fetters of transmission lines. Computers need to surf the internet through mobile phones, and mobile phones don't need to be placed next to computers or even taken out of their pockets. As long as it is within 10 meter, it can be transmitted freely without any restrictions.

Get rid of the trouble of wiring

When there are too many devices, the transmission line may be messy, difficult to arrange, inconvenient to carry and unsightly. Unplug the transmission line is even more difficult, not only to remember the corresponding relationship between different shapes of plugs and sockets, but sometimes to grope for a long time behind the computer. Replacing the traditional transmission line with Bluetooth can not only bid farewell to the messy transmission line, but also avoid memorizing the corresponding relationship between the shape of socket and plug. Through a few simple mouse operations or key settings, it is very convenient to establish a wireless transmission channel between devices.
