The concept of Bluetooth was first proposed. The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1m bytes per second, a maximum transmission distance of 10 meters, and can reach 100 meters by increasing the transmission power. Bluetooth technology is open to the world, with good compatibility on the global scale, and the whole world can be connected by low-cost invisible Bluetooth networks.
