The
Universal Serial Bus (USB), with one billion units in the installed
base, is the most successful interface in PC history. Projections
are for 3.5 billion interfaces shipped by 2006. Benefiting from
exceptionally strong industry support from all market segments,
USB continues to evolve as new technologies and products come to
market. It is already the de facto interconnect for PCs, and has
proliferated into consumer electronics (CE) and mobile devices as
well. USB enjoys strong brand recognition, has a well-recognized
logo, and is supported by an experienced governing body the USB
Implementers Forum (USB-IF).
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. To maintain the same usage
and architecture as wired USB, the Wireless USB specification is
being defined as a high-speed host-to device connection. This will
enable an easy migration path for today's wired USB solutions.

This paper
takes a brief look at the widely used interconnect standard, USB
and in particular, at the emerging technology of Wireless USB and
its requirements and promises.

Just about
any computer that you buy today comes with one or more Universal
Serial Bus connectors on the back. These USB connectors let you
attach everything from mice to printers to your computer quickly
and easily. The operating system supports USB as well, so the installation
of the device drivers is quick and easy, too. Compared to other
ways of connecting devices to your computer (including parallel
ports, serial ports and special cards that you install inside the
computer's case), USB devices are incredibly simple!
