| The two both belongs to the field of wireless technology applications, infrared rays is the first generation technology of wireless application, and RF belongs to the second ultimate technology. That is to say, infrared is the primary application stage of wireless application technology, while RF is the advanced stage of wireless technology, and the latter have wider market foreground. In the field of wireless product application field, it is only a matter of time for RF to replace infrared rays technology, the main performance difference between them are as follows:
