Bluetooth is a low-cost, high-capacity short-distance wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication capabilities. The name Bluetooth also has a legendary story. In the 10th century AD, when the Nordic princes were fighting for hegemony, the Danish king stepped forward. With his unremitting efforts, the bloody war was stopped and all parties sat at the negotiating table.

Through communication, the princes settled their differences and became friends. Because the King of Denmark loved eating blue plums so much that his teeth were dyed blue, he was known as the King of Bluetooth. Therefore, Bluetooth has become synonymous with communication. Today, a thousand years later, when the new wireless communication specification was introduced, people named it after Bluetooth. In 1995, Ericsson first proposed the Bluetooth concept.

The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1M bytes per second and a maximum transmission distance of 10 meters. It can reach 100 meters by increasing the transmission power. Bluetooth technology is globally open and has good compatibility around the world. The whole world can be connected through a low-cost invisible Bluetooth network.

Extended information:

When purchasing Bluetooth headsets, because there are many brands of mobile phones and headsets, the most troubling issue for consumers is the compatibility issue between mobile phones and Bluetooth headsets.

The manufacturer pointed out that Bluetooth headsets have three specifications: HeadsetPro-file (HSP), HandfreeProfile (HFP) and A2DP. HSP provides the communication required between the mobile phone (mobile phone) and the headset. Basic functions.

HandfreeProfile (HFP) adds certain extended functions based on HeadsetPro-file (HSP), which was originally only used to control mobile phones from a Bluetooth headset to a fixed car hands-free device. A2DP (Advanced Audio Distribution Profile) – allows the transmission of stereo audio signals. (Much better quality than mono encryption used for HSP and HFP). Determine the compatibility of the headset with your mobile phone.
