Nowadays, more and more people especially netizens have realized the trouble they met while using their computers: that is too many USB cords with not enough ports. As USB port has become a necessity hardware to communicate between a computer and external devices, but most computers only have 2 or 3 ports, one for the mouse, one for your keyboard, one for your phone to charge. What if we need to use a hard disk or other external devices like mp3、mp5、or camera? The limitation of number is really a problem many people have faced.

So, here comes the USB hub, which could be connected to one of the computer’s ports and provided 4 to 6 extra ports. That is to say, one can attach a lot of devices to the computer simultaneously by the application of USB hub. A USB hub can also be used as an active USB repeater since the cables are limited to five meters in length. It can charge from the computer, but when connecting devices that consume huge amount of power, an additional power supply is needed.

Wireless USB hub is a USB hub that is capable of working without cable. It assures the high speed wireless connectivity for any devices, and is able to send data under certain circumstances. This device can connect up to 127 devices directly to the host that connected in a working computer and is stationary. Without the limitation of cable, people can control everything from any place he likes instead of sitting in front of the computer screen, which also is beneficial to the eyes. It provide ultimate freedom and convenience.

The setting up of USB hub is not very complicated, just keep in mind that put the hub’s antenna in the right position to perform well. The antenna should be placed vertically with the computer otherwise disturbance might occur and will affect the reception. If you are also interested in integrated circuits, I can introduce one model briefly. The KTS184 series types are quad bilateral switches intended for the transmission of analog or digital signals, each of four independent bilateral switches has a single control signal input which simultaneously biases both the p and n device in a given switch on or off.
