Bluetooth is a low - cost high - capacity short - range wireless communication specification. Bluetooth laptop is a laptop with bluetooth wireless communication function. The name Bluetooth has a legendary story. In the 10th century, when the Nordic princes were vying for power, the King of Denmark stepped forward. With his unremitting efforts, the bloody war was stopped and all parties sat at the negotiating table. Through communication, the princes reconciled and became friends. Because the King of Denmark loves eating blueberries so much that his teeth are dyed blue, he is known as the Bluetooth King. Therefore, Bluetooth has become a synonym for communication. A thousand years later, when new wireless communications standards were introduced, people named it Bluetooth. In 1995, Ericsson first put forward the concept of Bluetooth. The Bluetooth specification operates in the microwave band, with a transmission rate of 1M bytes per second, a maximum transmission range of 10m, and up to 100m by increasing the transmission power. Bluetooth technology is globally open, with good compatibility in the global scope, the world can be connected through low-cost invisible Bluetooth network.
