What is Wireless USB?

The technology is advancing at such a rapid rate that after five or ten years, whatever we have now will be a thing of distant past. Things will become obsolete very fast and new & improved technologies will take their place. Things are getting very simplified with new inventions. First we had a telephone and had to stay near it but now we roam freely talking on a cell phone. We are living in a wireless world. All wired stuffs are being replaced by their wireless cousins with far superior quality.

Continuing with the wireless world, let me introduce you one of the best wireless data transfer device, the Wireless USB. This device can send or receive data from your computer easily and rapidly. Now you don't need a data cable or any other connecting device to transfer your data from your Flash Drive. The Wireless USB connects to your PC and transfers the data within a short period of time.

Created by the Wireless USB Promoter Group, the Wireless USB is a high bandwidth wireless radio communication device that works over a small range of around 10 to 15 meters. It is also called WUSB. Based on WiMedia Alliance's Ultra-WideBand common radio platform, the WUSB can transfer data at speed of around 450MB/sec for a distance of around 4 meters. As the distance increases the speed of data transfer is bound to decrease. At the distance of 10 meters the speed is 100MB/sec.

The WUSB technology is so revolutionizing that it easily allows you to connect your PC with more than 120 devices because it doesn't need any ports or hubs. Currently you have only 8-10 ports in your PC and some times this may become a limiting factor. With the help of WUSB, you can connect you computer with a printer, game controller, external hard disk, flash drive and many more devices all at the same time. To facilitate wireless data transfer WUSB provides you a Device Wire Adapter which acts like your USB Hub. Also a Host Wire Hub is attached to the USB port of your desktop/laptop which communicates with your device and transfers the data at a faster rate.

The Wireless USB faces major competition from Bluetooth. Bluetooth technology has been around for past few years and many advantages compared to WUSB like connection establishment, service level security and many more. Bluetooth specification 3.0 is going on and it will surely be better.

Though Wireless USB is not as much advantageous as Bluetooth, it is still in its nascent stage. With more time it will surely develop into a better data transfer medium.
