3. Wired USB
 Overview
 Plug/Play standard for peripheral devices
 Technical Details
 Host/Slave Connection
 PC (host) manages all transfers; peripherals (slave) just responds
 Supports 127 slaves per host
 Computer supplies power (up to 500 mA)
 Technical Details
 Data Rates
 Low Speed: 1.5 Mbps (Keyboards, mice, etc.)
 Full Speed: 12 Mbps (USB1.1)
 Hi-Speed: 480 Mbps (USB2.0)

5. Wireless USB Overview
Overview
 The USB was Developed and standardized by a group of leading companies
from the computer and electronics industries in 1995.
 USB specifications were developed by Compaq, IBM, Intel, Microsoft. Joined
later by HP, Lucent, and Phillips.
 These companies formed the USB Implementers Forum (USB-IF) as a non-
profit to publish specifications and provide a support organization.

6. Wireless USB Physical Design
Features of WUSB
 Transparent wireless USB connection
 Low power consumption
 Supported in any Operating Systems
 Speed/Range
 Scaleable speeds up over 1 Gbps
 Currently available 480 Mbps
 Frequency: 3.1 GHz to 10.6 GHz
 Range up to 300 meters

7. Reasons For Wireless USB
Wi-Fi
o Main drawback is high expense
o Another disadvantage higher power consumption
Bluetooth
o Bluetooth has shorter range
o Speed of bluetooth
Wired Issues
 Wires are restrictive (Hard to Maintain)
 Multiple wires can be a hassle
 Wires slower than wireless solutions

10. Wireless USB vs Bluetooth
 Bluetooth is a short-range cable replacement technology. The range of
bluetooth is 10 meter.
 On the other hand, the Wireless USB is capable of sending and
receiving data upto 300 meters.
 Also Wireless USB has maximum speed than bluetooth.

11. Wireless USB Implementations
Belkin Cable Free Hub

13. Future Scope
In future, every mobile phones, PDA's, Keyboard, Mice, Monitors,
Projectors, External Storage, etc will become wireless. Today wireless
USB is in the developing stage. In the middle of 2007 wireless USB will
dominate the market. Moreover, the scalable architecture of WUSB
enables the technology to upgrade the data transfer rate more than 1
GB/sec. Many companies are now joining the WUSB special interest
group and soon every product with USB 2.0 connectivity will enable
Wireless USB.

14. 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.
