Abstract
Overview
Wireless USB combines the benefits of wired USB with the convenience of a
wireless technology. This report addresses the development of a wireless USB,
and in particular it concentrates on several radio technologies on which WUSB
can be built (in the WPAN environment). The WUSB market comprises of at least
two major groups.
They are:
- A group based on the certified by the USB-IF technology-CWUSB
- A group that includes WUSBs based on any other technology (such as
CableFree, Bluetooth or IEEE 802.11 and other).
1. By using MB-OFDM UWB radio defined by the WiMedia Alliance, WUSB
may deliver signaling rates up to 480 Mbps at three meters (and up to 110 Mbps
at 10 meters). As a personal area wireless technology, Certified Wireless has
been designed for high-throughput, short-range communication.
WUSB has many significant advantages compared to other personal area wireless
technologies. Foremost is the existing strength of the certified USB brand
among consumers and the investment that manufacturers have in the USB
architecture. Certified Wireless USB extends this existing and well-understood
infrastructure rather than completely uprooting it and replacing with
something new.
The CWUSB specification was developed by seven promoter companies-Agere
Systems, Hewlett-Packard, Intel, Microsoft, NEC, Philips Semiconductors, and
Samsung. Over 150 other companies have since become contributors to the CWUSB
specification.
The report analyzes the UWB technology and market-the WiMedia version of this
technology is a basis for CWUSB. It also shows that currently the UWB
industry is not stable: several companies stopped operations in 2008-2009; the
WiMedia Alliance decided to stop its activity and to transfer the
technological intelligence to the USB-IF and Bluetooth SIG.
2. In this climate of uncertainty, it is worthwhile to take also a look
at the second group of WUSB. The report analyzes technological properties and
markets for Bluetooth and IEEE 802.11n as they relate to the WUSB development;
and it extends the UWB analysis to other than WiMedia versions.
The report also provides results of the survey of a large group of vendors'
products supplying WUSB/CWUSB and related devices.
Target Audience
This report is important to a wide population of researches, technical and
sales staff involved in the developing of wireless services and products. It
is recommended for both end users and vendors that are working with related
technologies. The report also helps to understand issues associated with
relationship between WUSB and other technologies.
Research Methodology
Considerable research was done using the Internet. Information from various
Web sites was studied and analyzed. Evaluation of publicly available marketing
and technical publications was conducted. Telephone conversations and
interviews were held with industry analysts, technical experts and executives.
In addition to these interviews and primary research, secondary sources were
used to develop a more complete mosaic of the market landscape, including
industry and trade publications, conferences and seminars.
The overriding objective throughout the work has been to provide valid and
relevant information. This has led to a continual review and update of the
information content.
