Bluetooth is a low-cost, high-capacity, short-range wireless communication specification. Bluetooth laptop, is a laptop with Bluetooth wireless communication. Bluetooth this name there is a legendary story it. In the 10th century A.D., the Nordic vassals were fighting for supremacy, and the King of Denmark stepped forward, and under his tireless efforts, the bloody war was stopped, and all parties sat down at the negotiation table. Through communication, the lords released their differences and became friends. Since the King of Denmark loved to eat blue plums so much that his teeth were stained blue, he was known as King Bluetooth, so Bluetooth became synonymous with communication. Today, a thousand years later, when a new wireless communication specification was introduced, people again used Bluetooth to name it.
In 1995, Ericsson was the first to introduce the Bluetooth concept. The Bluetooth specification uses the microwave frequency band to work, with a transmission rate of 1M bytes per second and a maximum transmission distance of 10 meters, which can be up to 100 meters by increasing the transmit power. Bluetooth technology is globally open, with good compatibility on a global scale, and the world can be connected through a low-cost invisible Bluetooth network.
