I would like to thank our principal Dr. O. S. Deshmukh, Shri Shivaji Science and Arts
College, Chikhli, for the preparation of this seminar. Our department of Computer Science
gave me this opportunity to present a Seminar on my topic “WIRELESS USB”. Also, I
would like to thank the teachers Dr. A. B. Kadam, Dr. M. E. Jadhav, and Dr. S. S. Gaikwad
for helping me gather information about my topic and help to go in-depth on the topic. Also,
I, am very thankful to our non-teaching staff Mr. S. A. Chavan and Mr. P. S. Sonune to solve
the technical difficulties. I am genuinely thankful to my classmates, my friends, and my
parents, I am absolutely sure that this knowledge will help me to grow in the near future.

“WIRELESS USB”
1. INTRODUCTION
The original motivation for USB came from several considerations, two of the
most important being:
Ease of use and Port expansion.
The lack of flexibility in reconfiguring PC had been acknowledged as the
Achilles’ heel to its further deployment. The combination of user friendly graphical
interfaces and the hardware and software mechanisms associated with new-generation bus
architectures have made computers less confrontational and easier to reconfigure.
However from end users point of view, the PC’s I/O interfaces, such as serial parallel
ports, keyboard mouse interfaces etc. did not have the attributes of plug and play.
The addition of external peripherals continued to be constrained by port
availability. The lack of a bidirectional, low cost, low-to mid speed peripheral bus held
back the creative
proliferation of peripherals such as storage devices, answering machines, scanners,
PDA’s, keyboards, mice etc. Existing interconnects were optimized for two point
products. As each new function or capability was added to the PC, a new interface has
been defined to address this need.

2. WIRED USB
A USB system has an asymmetric design, consisting of a host, a multitude of
downstream USB ports, and multiple peripheral devices connected in a tiered-star
topology. Additional USB hubs may be included in the tiers, allowing branching into a
tree structure, subject to a limit of 5 levels of tiers.
A USB host may have multiple host controllers and each host controller may provide
one or more USB ports. Up to 127 devices, including the hub devices may be connected
to a single host controller. The USB Specification provides a selection of attributes that
can achieve multiple price/performance integration points and can enable functions that
allow differentiation at the system and component level.

3. FEATURES OF WIRELESS USB TECHNOLOGY
Wireless USB will build on the success of Wired USB. An important goal of the
WUSB Promoter Group is to ensure that wireless USB offers users the experience they
have come to expect from wired USB. Toward that end, the Wireless USB standard is
being designed to support the following features.
• Backward compatibility - Wireless USB will be fully backward compatible with the
one billion wired USB connections already in operation. Moreover, Wireless USB
will be compatible with current USB drivers and firmware and provide bridging from
wired
USB devices and hosts.
• High performance - At launch, Wireless USB will provide speeds up to 480 Mbps, a
performance comparable to the wired USB 2.0 standard and high enough to provide
wireless transfer of rich digital multimedia formats. As UWB technology and process
technologies evolve, bandwidth may exceed 1 Gbps.
• 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.

4. PERFORMANCE
WUSB performance at launch will provide adequate bandwidth to meet the
requirements of a typical user experience with wired connections. The 480 Mbps initial
target bandwidth of WUSB is comparable to the current wired USB 2.0 standard. With
480 Mbps being the initial target, WUSB specifications will allow for generation steps of
data throughput as the ultra wideband radio evolves and with future process technologies,
exceeding limits of 1 Gbps.
The specification is intended for WUSB to operate as a wire replacement with
targeted usage models for cluster connectivity to the host and device-to-device
connectivity at less than 10 meters. The interface will support quality delivery of rich
digital multimedia formats, including audio and video, and will be capable of high rate
streaming (isochronous transfers).

5. SECURITY AND ASSOCIATION
WUSB security will ensure the same level of security as wired USB. Connection
level security between devices will ensure that the appropriate device is associated and
authenticated before operation of the device is permitted. Higher levels of security
involving encryption should be implemented at the application level. Processing overhead
supporting security should not impose noticeable performance impacts or add device
costs.
One of the primary objectives when implementing a wireless interconnect is that it
is easy to install and use. Wired connections provide the user with implied expectations,
that is that the device is connected as specified by the user when they install the wire.
When the wire is installed, the user has basic expectations and when these expectations do
not take place (plug does not fit), there is a known recourse.
Wireless connections, on the other hand, due to environmental characteristics, may
establish connection paths that are not obvious. In fact, it may not be obvious when a
device is connected. So WUSB devices installed for the first time should automatically
install drivers, security features, and so on and associate with systems that they can
interact with.
The concepts of 'turn on and use it' with an easy setup procedure will be employed.

6. CONCLUSION
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-wide band 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.
