The background of the birth of Bluetooth
1994, Dr. Jaap Haartsen proposed a short-range radio communication technology in Ericsson, named after "Bluetooth", in order to unify the fragmented situation. Bluetooth was originally designed as a short-range UHF radio wave between 2.4-2.485 GHz. At that time, it was mainly used to replace RS-232 telecommunication cable, occupying a frequency very similar to that of Wi-Fi, but its application range is shorter and its power consumption is relatively lower.
1998, Toshiba, Ericsson, IBM, Intel and Nokia jointly put forward the technical standard of short-range wireless digital communication. The Bluetooth standard was formally formed. 1999, the first consumer-grade Bluetooth product was introduced and installed on the hands-free mobile Bluetooth headset. In 2000, the first Bluetooth-equipped chipsets, mice and mobile phones were released. 200 1, the first Bluetooth-enabled mobile phone was launched. Nowadays, Bluetooth is widely used to transmit audio, files, pictures and so on.
