Wireless USB allows devices to connect to computers without cables at speeds up to 480 Mbps, comparable to USB 2.0. It uses radio frequency waves over a 10 meter range to connect devices like printers, hard drives, and cameras in a simple and low-cost way. Wireless USB maintains the USB architecture and connectivity models to provide an easy migration path from wired USB. It provides the same security and performance as a wired connection with the advantage of cable-free use of devices.

3. INTRODUCTION
 The Wireless USB is the first the high speed
Personal Wireless Interconnect.
 Wireless USB will build on the success of
wired USB, bringing USB technology into
the wireless future.
 Usage will be targeted at PCs and PC
peripherals, consumer electronics and mobile
devices.

4. What is wireless communication?
 In modern usage, the term WIRELESS COMMUNICATION
refers to communication without cables or cords, chiefly using
radio frequency and infrared (i.e., IrDA) waves. E.g., wireless
networking of computers.
 Similarly “Wireless Universal serial Bus (W.U.S.B.)”
connects devices like printers, mouse, external hard drives and
digital camera to our PC’s without a single wire and speed and
accuracy is still the same as wired connection.
 This technology operates over a range of around 10 meters(30
feet).

5. USB
 USB (Universal Serial Bus) is a way of setting
up communication between a computer and
peripheral devices.
 USB can connect computer peripherals such
as mice, keyboards, PDAs, game pads and
joysticks, scanners, digital cameras, printers,
personal media players, flash drives, and
external hard drives.

6.  USES OF WUSB.
 Wireless USB is used in game
controllers, printers, scanners, digital
cameras, MP3 players, hard disks and flash
drives.
 It is also suitable for transferring parallel
video streams, while utilizing the Wireless
USB over UWB bandwidth.

7. Some of the WUSB devices.

8. FEATURES
 HIGH PERFORMANCE :
At launch, Wireless USB will provide speeds up to 480 Mbps, a
performance comparable to the wired USB 2.0 standard .
 SIMPLE, LOW COST IMPLEMENTATION:
Implementation will follow the wired USB connectivity models as
closely as possible to reduce development time and preserve the low-cost,
ease-of-use model that has made wired USB the interconnect of choice.
 AN EASY MIGRATION PATH :
To enable an easy migration path from
wired USB, Wireless USB will maintain the same usage models and
architecture as wired USB.

9. Security
Wireless USB will provide the same
level of security as wired USB. Higher levels
of security involving encryption will be
implemented at the application level. At the
same time, an important goal of the
specification is to ensure that security
requirements do not impact the performance or
cost of Wireless USB applications.

10. PERFORMANCE
 WUSB will operate as a wire replacement with targeted usage models
for device-to-device connectivity at least 10 meters.

11. PRACTICAL IMPLEMENTAION

12. USAGE APPLICATION

13. Wireless USB Vision

14. Wireless USB Implementations
 Belkin Cable Free Hub
 Released Dec, 2006
 Dongle attaches to PC
 Retail price of $199.00
 Speeds up to 480 Mbps

15. Typical Home Applications
 PCs and peripherals
 PDAs
 External storage devices (HDDs)
 HDTV's and STB’s
 Game consoles
 Digital cameras
 Digital camcorders
 DVD players
 MP3 players
 CD players
 Wireless speakers

16. ADVANTAGES
 You can connect wirelessly.
 It is the easy and secure from plugging it
in / unplugging it
 You do not need to have a network cable
between the device and the network.

17. DISADVANTAGES
 Unless the security is not properly setup,
both your laptop or desktop and the
network you are connecting to cannot be
compromised and your data can be
accessed and read by others.
 The hardware is small, it can get
damaged, lost or stolen.

18. FUTURE & CONCLUSION.
 Early 2007
 Initial devices being produced
 Late 2007
 Expect WUSB being built into laptops, PCs, multimedia
devices
 2008
 Visiongain research firm predicts increase of WUSB by 400
percent
 2009-2010
 Wide scale interoperability
