You can connect USB peripherals to your computer from up to 150 feet (45 meters) away with this adapter. Use a patch cable/straight-thru cable (Cat-5, 5e, or 6) to connect the two adapters together.Note: the distance and presence of adapters may affect the performance of some devices. With distance more than approximately 5 feet (1.5 meters), you may need to use a powered USB hub, as the USB port on your computer does not supply enough power to stretch over distance. Powered USB hub not included as part of this package. This adapter set is to be used with a patch cable, also called a straight-through cable.
