First Wireless USB Devices

Wireless USB devices will start arriving the market in the third quarter(around September), and promises help for consumers frustrated with cables linking to their digital cameras, external disk drives, external dvd burners, music players, digital cameras etc.

Wireless USB, also known as WUSB, will permit the same data transfer speed of 480mbps (megabits-per-second) as the current wired USB 2.0 standard, but only requires tiny radios inside the computer or devices instead of cables.

“The first wireless USB devices are going to be external hard drives, cameras and printers”, said Jeff Ravencraft, chairman of the USB Implementers Forum and an Intel technology strategist.

In order for the wireless USB (wUSB) to be ready for the market, some aspects of this new technology have to be ironed out. A big step towards this was announced on Monday by the USB standards group, by introducing the Wireless Association Specification.

The Wireless Association Specification makes sure only authorized connections are made betweed PCs and wireless usb devices.

Since the arrival of Universal Serial Bus connection technology, it has been gaining in popularity. It has become the most compatible connection prefered by PC-users for digital cameras, mobile phones, mp3 gadgets, PDAs (personal digital assistants), scanners, dvd burners and many other devices. Now the future looks even better! The Wireless Association Specification heals our problems by enabling us to connect up to 127 USB Wireless devices to one computer.

There will be two ways of setting up the association between an USB Wireless device and the PC. In the first way, the specification requires you to connect the device with your PC via cable and configure their association for future wireless connections/links. In the second possibility the wUSB device will display a number that the user will need to type into the PC in order to create the association.

Wireless USB uses a wireless communication technology called ultrawideband (UWB). While 802.11g uses a relatively narrow frequency range fixed on 2.4GHz radio waves, UWB uses a very broad range from 3.1GHz to
10.6GHz.

The technology commonly used in wireless networks is Wi-Fi, also identified by it’s standard number, 802.11 . Nowadays Wi-Fi can be found in all new notebooks and even in some mobile phones and cameras. However manufactures might consider switching to UWB because of its simplicity and the fact that it consumes about half the power of 802.11 technology.

“With very high-end phones and cameras, you’re starting to see 802.11. The issue in those mobile devices is the battery power and cost of battery life in implementing that,” Ravencraft said. “The cell phone and camera guys see UWB as a very good solution for point-to-point connections with very low power.”

To connect Wireless USB devices on your computer you will need an add-in card or plug-in device. It might take a while until mainboard manufacturers bring built-in wUSB (wireless USB) to the market.

    Thank goodness! When I bought a new PC, I made sure it had a 13-in-1 card reader so I didn't have to bother with cables for my camera and phone any more. Hardly eliminates the problem for other USB devices though. WUSB sounds great. Or at least it will when I can afford to replace all my existing USB devices with WUSB variants!
