Infrared communication

infrared communication, as the name suggests, is transmitted through infrared. In the early stage of computer technology, data is transmitted through cable, and the cable transmission is inconvenient, and special interface is required. Then there is a wireless data transmission technology such as infrared, Bluetooth, 802.11.

In the early infrared communication technology, there are several infrared communication standards, and the infrared equipment between different standards cannot be infrared. In order to enable various infrared equipment to interconnect, in 1993, more than 20 large manufacturers have established an infrared data association (IRDA), unified the standard of infrared communication, which is widely used IRDA infrared data communication protocol and standardization .
