Q. What is Wireless USB?
Certified Wireless USB from the USB-IF is based on WiMedia’s Ultra-Wideband (UWB)
radio platform, enabling products from the PC, CE, and mobile industries to connect
using a common interface at up to 480Mbps. This technology was created by the
Wireless USB Promoter Group-Agere Systems; Hewlett Packard, Intel, Microsoft, NEC
Electronics, Philips, and Samsung-aided by over 100 contributing companies. This new
wireless extension of USB combines the speed and security of wired technology with
the ease-of-use of wireless technology. Certified Wireless USB ensures consumers
have an easy, secure way to connect their home, office and mobile devices without a
cable-without sacrificing speed. –USB-IF.org

Q. What is Ultra-Wideband (UWB) technology?
FCC defines UWB as a radio transmission with a spectrum that occupies more than 20
percent of the center frequency, or a minimum of 500 MHz while adhering to certain
output power limits. UWB technology offers flexibility, robustness, and good ranging
capabilities, making it well suited for applications that need a high data rate over a short
transmission range.

transmission range.
Q. How far can UWB signal be transmitted?
Because the goal of UWB is to transmit higher bandwidth signals at low power output,
the range is not meant to surpass what is called a Wireless Personal Area Network
(WPAN), and general maximum distance for transmission is 30 feet or 10 meters.

Q. What is a WPAN?
Wireless Personal Area Network or WPAN can be defined as any area around you,
typically within a range under 10 meters, where you plan on using personal devices and
peripherals and have them communicate with one another, wirelessly. Such benefits
include file transferring and streaming video without the needs of wires/cables.

Q. Are there any signal interference of UWB and other wireless
technologies?
technologies?
UWB operates at a low power frequency range of 3.1GHz to 10.6 GHz. This is out of
the range of all other wireless technologies (802.11g and 802.11g), and devices such as
microwaves ovens and cordless phones that typically operate in the 2.4GHz range.
One of the main goals of UWB is to allow streaming video wirelessly, and in order for
that to be successful, it needs its own spectrum to operate and alleviate interference. If
WPAN were to use a wireless technology that operated in the 2.4GHz range, there
would be limited space to send signals without interference. There are no signal
