Therefore, in small mobile devices to obtain a wide range of applications. Through the infrared interface, various types of mobile devices to exchange data freely. Infrared is a wavelength between 750nm to 1mm of the electromagnetic wave, its frequency is higher than microwaves but lower than visible light, is a person's eyes can not see the light. As the short infrared wavelengths, the diffraction barrier is poor, it is more suitable for applications requiring short-range wireless communication applications, data transmission for point to point line. Infrared Data Association (IRDA) will be used for infrared data communication wavelength range of 850nm to 900nm limited within. You will need this kind of cell phone jammer during the meeting.
Cell phones equipped with infrared interface for wireless Internet access is very simple, no cable and PC CARD, as long as the agreement will be able to set up an infrared connection directly to the Internet. Infrared interface is now in the world is a widely used wireless technology, is a large number of hardware and software platform support; electrical pulses through the data and infrared light pulses to achieve conversion between the wireless data transceiver. To replace the cables connecting the new point to point communications standard compatible with the earlier communication standard small-angle (30 degree cone angle or less), short-range, point-line data transfer, confidentiality, a high transmission rate, the current rate of 4M The FIR technology has been widely used, 16M rate VFIR technology has released the main advantages of infrared technology. And then, cell phone jammer can be switched on again.
The cell phone and its wireless transmission of data between computers can; can be the same between devices with infrared interface for information exchange; while infrared interface, eliminating the need for downloads or other costs incurred in the exchange of information; docking due to the need to transmit information, more security strong; infrared technology Disadvantages: short-distance communication, communication process can not be moved, the case of interrupted communication barriers; infrared communication technology, the main purpose is to replace the cable connection for wireless data transmission, single function, poor scalability. Infrared technology feature. Infrared communication technology for low-cost, cross-platform, point to point high-speed data connection, especially embedded systems. Then cell phone jammer can work well again for another 12 hours.AAC: the sound quality at high bit rates after the MPC, at high bit rates and low bit rates are very good appearance.
