The first Wireless USB implementations will likely be in the form of discrete silicon that will be introduced in a number of form factors. These may include add-in cards and dongles along with embedded solutions to support the technology's introduction and subsequent rapid ramp up. But the wireless future will arrive once WUSB, along with the common ultra wideband platform, becomes a standard part of every processor and chipset and is integrated in CMOS silicon. As the latest iteration of USB technology, wireless USB (WUSB) will offer the same functionality as standard wired USB devices but without the cabling. As the new Wireless USB Promoter Group prepares to develop the specifications that will help standardize the technology, the industry is planning products that can take advantage of the convenience and mobility that this new device interconnect will offer.

2. INTRODUCTION
USB stads for universal serial bus.
Wireless usb is a high bandwidth.
wireless radio communication protocol created by the
Wireless USB Promoter Group.
A ultra-wideband (UWB) common radio platform,
which is capable of sending 480 Mbit/s at distances
up to 3 metres (9.8 ft) and 110 Mbit/s at up to 10
metres (33 ft).

3. DEVLOPEMENT
The Wireless USB Promoter Group was formed in
February 2004 to define the Wireless USB protocol.
In May 2005, the Wireless USB Promoter Group
announced version 1.0 of the Wireless USB
specification.
In June 2006, five companies showed the first multi-
vendor interoperability demonstration of Wireless
USB

4. USES
Wireless USB is used in game controllers, printers,
scanners, digital cameras, portable media players,
hard disk drives and flash drives.

5. COPATIBILITY OF OLDER
HARDWARE
The WUSB architecture allows up to 127 devices to
connect directly to a host. Because there are no wires
or ports, there is no longer a need for hubs.
WUSB introduced a new Device Wire Adapter (DWA)
class.
The HWA is a USB 2.0 device that attaches externally
to a desktop or laptop's USB port or internally to a
laptop's MiniCard interface.

7. CONCLUSION
Wireless usb implementation will likely in form
discreate silicon and may include card ,dongle etc.
wireless USB (WUSB) will offer wideband platform.
The same functionality as standard wired USB devices
but without the cabling.
Wireless USB Promoter Group prepares to develop
the specifications for more connect devices.
USB help standardize the technology.

8. ADVANTAGES
you can connect wirelessly, you dont need to have a
network cable between the device and the network.
you can connect fairly easily at home, work, mulit
offices.
you can move around or work at any avaiable or
suitable location without having to be near a socket.
 you can take it out and use elsewhere.
You are plugging/ unplugging it, security because you
know whether it's plugged in or not so you know no-
one is accessing your machine.

9. DISADVANTAGE
unless the security is properly setup both your laptop
and the network .
it can get damaged, lost or stolen.
reception is limited by distance and structures
between you and the antenna (radio waves don't
always propagate in a linear fashion in building, they
can get blocked by steel structure.
some older wireless networks can get very slow if
there are lots of people int he same area all trying to
use the network (effectively trying to use the same
radio bandwidth).
