KDDI R & D laboratory, use infrared wireless technology send USB 2.0 signals has been developed. Through this technology, PC and mobile communications equipment can no longer be required USB cable wireless data communications. New technologies developed through the “USB infrared converter” device, the USB 2.0 electrical signals into optical signals of infrared equipment to complete the wireless transmission. This converter installed infrared communication module, the transmission bandwidth of 1Gbps.
According to the specifications of USB 2.0, the corresponding signal must be USB host and USB devices to connect after being sent back to within 1.5us. Therefore, it needs more than the speed of the signal to 1.5us infrared optical signal converter.
KDDI R & D laboratory is equipped with a USB infrared converter with a “virtual USB device / host function”, it will automatically generate the necessary rapid response signal. As a result, USB host to identify the converter, which will identify the USB.
KDDI R & D lab, this USB to infrared converter for embedded devices in the future, while the technology to comply with the IrDA (Infrared Data Association), the relevant technical specifications.
