The infrared interface is the configuration standard for a new generation of mobile phones. It supports data exchange between mobile phones and computers and other digital devices. Infrared communication has the characteristics of low cost, convenient connection, simple and easy to use, and compact structure, so it has been widely used in small mobile devices. Through the infrared interface, all types of mobile devices can freely exchange data.
Infrared is an electromagnetic wave having a wavelength between 750 nm and 1 mm. Its frequency is higher than that of microwave but lower than visible light, and it is a kind of light that human eyes cannot see. Due to the short wavelength of infrared light, the diffraction capability of obstacles is poor, so it is more suitable for applications where short-range wireless communication is required, and point-to-point linear data transmission is performed. The Infrared Data Association (IRDA) limits the wavelength of light waves used in infrared data communications to within 850 nm to 900 nm.
A mobile phone equipped with an infrared interface for wireless Internet access is very simple and does not require a connection cable and a PC CARD. You can connect to the Internet directly by setting up an infrared connection protocol.
Infrared interface is a kind of wireless connection technology that is widely used worldwide. It is supported by numerous hardware and software platforms. Wireless data is transmitted and received through the mutual conversion between data electrical pulses and infrared light pulses.
Infrared interface features:
Used to replace point-to-point cable connections New communication standards Compatible with early communication standards Small angles (within 30 degrees cone angle), short distances, point-to-point linear data transmission, high confidentiality transmission rates, current 4M rate FIR technology Widely used, the 16M rate VFIR technology has released the main advantages of infrared technology:
It enables wireless transmission of data between a mobile phone and a computer; information exchange can also be performed between devices having the same infrared interface; and at the same time, the infrared interface can save costs incurred in downloading or other information exchange; since it requires docking to transfer information, the security is relatively high. Strong; shortcomings of infrared technology:
The communication distance is short, the communication process cannot move, and the obstacle communication is interrupted. The main purpose of the infrared communication technology is to replace the cable connection for wireless data transmission, which has a single function and poor scalability. Infrared technology features Infrared communication technology is suitable for low-cost, cross-platform, point-to-point high-speed data connections, especially embedded systems.
The main application of infrared technology: device interconnection, information gateway. After the devices are interconnected, the exchange of files and information in different devices can be completed. The information gateway is responsible for connecting information terminals and the Internet.
Infrared communication technology has been supported and adopted by numerous hardware and software vendors worldwide. Currently, mainstream software and hardware platforms provide support for it. Infrared technology has been widely used in mobile computing and mobile communications devices.
