USB(Universal Serial Bus)
USB:-
Universal Serial Bus .
is a specification to establish communication between
devices and a host controller.
Wired USB:-
USB is plugged for peripheral devices.
There are used to transfer data from one device
to another device.
Eg:-As we transfer data from pen drives to
Pc’s and vise versa.
DATA RATES:-
Low speed:1.5 mbps
Full speed:12 mbps
High speed:480 mbps
Wireless USB
It is the natural evolution .It is the extension of USB .
It was first introduced in 2004 by wireless USB promoter group.
Wireless USB is short-range, high bandwidth wireless radio communication protocol .
Wireless USB are developed by seven companies: Intel corporation ,HP , LSI , logic , Microsoft corporation ,NCE corporation ,NXP semiconductors ,Samsung electronics.
Development
The Wireless USB Promoter Group was formed in February 2004 to define the Wireless USB .
In May 2005, the Wireless USB Promoter Group announced the completion of the Wireless USB specification.
In June 2006, five companies showed the first multi-vendor interoperability demonstration of Wireless USB.
A laptop with an Intel host adapter using an Alereon PHY was used to transfer high definition video from a Philips wireless semiconductor solution with a Realtek PHY, XP drivers developed for Wireless USB.
DESIGN
Certified wireless USB was designed from the ground up to address the specific challenges of wireless communication and personal networking.
This design is based on the ultra-wide band(UWB) radio system called orthogonal frequency division multiplexing(OFDM).
FEATURES
SPEED/RANGE:
scalable speeds up over 1Gbps.
currently 480Mbps at 3mt;110Mbps at 10mt.
FREQUENCY:
3.1 GHz to 10.6GHz.
divided into 14 bands and 5 groups .
each band in 528MHz wide.
OFDM symbols are interleaved across all bands.
provides protection against multi-path/interface.

Hardware support
All of your current USB peripherals will still utilize the wired USB connection they always have.
Wireless USB, however, opens up a variety of new types of devices. Wireless USB hubs, or bridging devices.
They will allow you to plug wired USB peripherals into the hub, but the hub itself will enjoy a wireless connection to the computer.
In this way, you can experience the convenience of wireless connectivity without replacing all your USB peripherals with wireless versions.
HWAs are physically connect to the computer via USB 2.0 or a laptop's CardBus or ExpressCard interface, and provide Wireless USB host capability to any number of WUSB devices.
DWAs, or "Wireless USB hubs ", allow existing wired USB devices to be used wirelessly with a WUSB host.
Operating system support
All major computer operating systems are planned to support wireless USB. However, at the moment.
wireless USB functionality is provided only by proprietary software drivers and is largely device-specific.
As the standard matures and subsequent releases of your favorite operating system become available.
Apple has not released any information regarding Mac OS X support for Certified Wireless USB.
How does it work?
Plug in the included your laptop or your desktop to make it wireless USB enabled .
Connect to your printer ,digital camera , external hard drive ,and any other peripheral
to IOGEAR’s wireless USB hub.
Wirelessly print ,download pictures and back up files or play video at blazing speed of up to 480Mbps.
Limitations
In a rush towards a totally wireless desktop, there is a danger that the practical limitations of USB become lost in the marketing fervor.
A number of Wireless USB adapters are available, but most of them are rather limited when it comes to resolution/bandwidth.
Unless the security is properly setup both your laptop and the network you are connecting to can be compromised and you data be read by others the hardware is flaky, it can get damaged, lost or stolen.
