Bluetooth technology

Bluetooth is a radio technology that supports device short-range communications (typically within 10m). It can exchange wireless information between devices including mobile phones, PDAs, wireless headsets, laptops, and related peripherals. The standard for Bluetooth is IEEE 802.15, which operates in the 2.4 GHz band and has a bandwidth of 1 Mb/s.

"Bluetooth" was originally a king of uniting Denmark in the 10th century. He unified Sweden, Finland and Denmark at that time. Using his name to name this new technical standard contains the meaning of uniting the fragmented situation. Bluetooth technology uses high-speed frequency hopping (FH, Frequency Hopping) and time division multiple access (TDMA, Time Divesion Muli-access) and Other advanced technologies to inexpensively place several digitized devices (various types of mobile devices, fixed communication devices, etc.) at short distances. Computers and their terminal equipment, various digital data systems, such as digital cameras, digital cameras, and even various household appliances and automation equipment, are linked together in a mesh. Bluetooth technology will be a unified bridge for various peripheral devices in the network. It eliminates the connection between devices and replaces them with wireless connections.

Bluetooth is a short-range wireless communication technology. Electronic devices can be connected to each other through Bluetooth, eliminating the need for traditional wires. Through the wireless receiver on the chip, electronic products equipped with Bluetooth technology can communicate with each other within a distance of ten meters, and the transmission speed can reach 1 megabyte per second. In the past, the transmission technology of the infrared interface required the distance of the electronic device within the line of sight, and now with the Bluetooth technology, such trouble can be eliminated.
