In the 10th century AD, the Nordic lords contend for the hegemony, and the Danish king came forward. With his unremitting efforts, the bloody war was stopped, and all parties sat at the negotiating table. Through communication, the princes bury their hatchets and become friends. Because the Danish king loves to eat blue plum, so that the teeth are dyed blue, known as the Bluetooth king, so Bluetooth has become synonymous with communication. Today, a thousand years later, when new wireless communication specifications were introduced, people used Bluetooth to name it. In 1995, Ericsson first proposed the concept of Bluetooth. The Bluetooth specification works in the microwave band, with a transmission rate of 1 Mbytes per second and a maximum transmission distance of 10 meters, which can reach 100 meters by increasing the transmission power. Bluetooth technology is open to the world, with good compatibility on a global scale, and the world can be integrated through a low-cost invisible Bluetooth network.
