Wireless USB aims to provide high-speed wireless connectivity using UWB technology. It allows data transfer between devices like computers, phones and electronics at speeds up to 480 Mbps within 3 meters. The key advantages are eliminating wires, providing mobility, and supporting bandwidth-intensive applications like video transfer. It uses multi-band OFDM and security features similar to wired USB. Early implementations included wireless hubs and hard drives, but widespread adoption depends on addressing interference issues and developing more compatible products.

3. Based on Ultra-Wideband
(UWB) RF technology
USB is a technology for
transmitting data over a
large bandwidth (>500 MHz)

4. • Wires are restrictive
• Multiple wires can be a
hassle
• Wires slower than wireless
solutions
Wired Issues
• Bluetooth
• Bandwidth of 3 Mbps not
enough for higher
demand applications
(Video, HDTV, Monitor)
• WiFi
• Expensive
• Too much power usage
for mobile devices
Current wireless
solutions
inadequate

5. Wireless version of USB; same features but high speeds
Interoperable across three major platforms
• Consumer Electronic devices (digital video/audio)
• Mobile devices (cellular phones, PDA)
• Personal Computing (laptop, PC, printer, peripherals)
High bandwidth to support demanding data transfer (High Definition,
Monitors)
Mobile friendly
• Low power usage
• Inexpensive costs
• Small physical implementation
High level of security

7. Speed/Range
• Currently 480 Mbps at 3 m; 110 Mbps at 10 m
Frequency: 3.1
GHz to 10.6
GHz
• Divided into 14 bands; 5 groups
• Each band is 528 MHz wide
• OFDM symbols are interleaved across all bands
• Provides protection against multi-
path/interference

8. Same level of
security as
wired USB
Wireless
interconnect
is easy to
install and
use
Wired
connections
provide the
user with
implied
expectations
Two major
components:
Association
and
Encryption

9. Interference Issues
• Potential conflict to
devices on same
frequencies
• Switches to
frequencies not
being used
• Conflict issues are
more when
overpowered
Competing
Standards
• Cable-Free USB
• USB-Implementers

14. Appears well
designed; good
support
Slow start of
products
Promises a lot; Will it
deliver?
Security is very
important
• Will it really catch on?
• More products need
to be developed
