INSTALLATION AND SETUP
The initial set up of the Wireless USB adapter
set is a standard Windows installation process,
similar to driver installation of USB devices. It
does not require any technical skills or
understanding of wireless technology, and can
be easily performed with the help of the
“Getting Started” leaflet (on the right). The
entire process setup takes 5-7 minutes.
1. The package includes the two adapters, a
table adapter, CD, and power supply.
2. Enter CD and follow instructions to install
drivers & software.
3. Connect the PC adapter to PC.
4. Perform association (pairing) between the PC
adapter and the device adapter. Pairing is
done for security purposes, and is performed
by attaching both adapters simultaneously to
the PC. After a few seconds a message is
displayed that pairing is complete.
5. Remove the device adapter from the PC and
place it in the table adapter.
6. Attach a USB cable to connect a USB device
(e.g, printer, hard disk drive) to the table
adapter.
7. Connect the power supply to the table
adapter.
8. Wireless USB communication is enabled and
the PC can communicate with the USB device.

PERFORMANCE
The Wireless USB adapter set is based on Ultra-wideband technology, which is a personal area network (PAN)
technology, designed to provide wireless coverage in the range of 10 meters (30 feet). As such, the adapter set
provides full room coverage, both with line of site and with no line of site (note that it is not designed to operate
across rooms). This allows you to locate USB devices in the room without the limitation of the USB cable length.
To test performance, the adapter set was used in a large meeting room measuring 10x4 meters (30x12 feet). The
laptop and PC adapter were placed in one side of the room, and each time a different device was placed in the
other side of the room. To verify line of site, and non-line of site behavior, devices were sometimes placed on a
shelf or within a closet, and people were sitting and passing within the wireless link. Performance was not affected
by increasing the range, or by a lack of line of site between adapters.

Link establishment was tested by exiting the room with the laptop to intentionally break the wireless link between
the notebook and an external hard disk drive. Then, once returning to the room, the wireless link was
automatically re-established, enabling connectivity to the hard drive, without requiring any involvement. This
simulates a common scenario where your notebook is connected to a peripheral device and you leave the room
with the notebook, returning after a while. With wired USB you have to disconnect and connect devices, while
with Wireless USB the adapter set automatically re-connects you to the device once back in range, with no further
action.

Link robustness was tested using a thumb drive (flash), as it proved as a stable device. Testing was performed
ausing a variety of methods, as described below:
•
Blocking inside the link. Device adapter was blocked for 30 seconds by placing both hands over the
adapter to break the link. After removing hands, the connection recovered automatically. Same was
performed with the PC adapter.
•
•
The PC adapter was taken out of the PC and then plugged back. The link was re-established automatically.
The device adapter was taken out of its table stand and then returned after several seconds. The link was
re-established automatically.
•
•
The device power cable was removed from the table stand and then returned after several seconds. The
link was re-established automatically.
The PC was switched each time to a different power management state - shut down, reset, hibernate and
standby. After returning back to operating mode, the wireless link was established automatically in each
of these scenarios.
Data rate was measured with a variety of USB devices:
•
•
•
With the majority of devices (such as camcorders, digital cameras), Wireless USB achieved at least 45% of
wired connection.
With some devices, such as printers and DSLR cameras, Wireless USB provided a throughput that was
almost identical to wired USB. (Printers: 80-90% of wired, DSLR: 81% of wired).
Hard Drives were the fastest USB 2.0 type of devices. The measured throughput with Wireless USB was
close to ~ 70Mbs which was roughly ~ 28% of the wired throughput.

USE CASES AND USER EXPERIENCE
The following section outlines the testing performed with different types of USB devices, illustrating the use case
and describing the measured performance.
MULTI FUNCTION PRINTER
Testing was performed first with a USB
cable, then with the adapter set, connected
to an HP All-in-One printer (model C8180).
For wireless, the printer was placed in one
side of a meeting room, and files were sent
to print from a laptop, while sitting at the
other side of the room. In addition, testing
was performed for wirelessly scanning and
reading data from the printer’s built-in card
reader.
Two measurements, commonly used by the
print industry, were used: first page out
(measuring the time from sending the file
from the printer till the first page completes
printing) and Pages per Minute (PPM).
The table below shows that there was hardly any difference in user experience between wired and Wireless USB
connectivity. Also note that wireless performance remains the same when increasing the distance from 3 meters
to 8-10 meters.

The multi-function printer was also tested with wireless scanning and reading data from the built-in card reader.
EXTERNAL HARD DISK DRIVE
A Maxtor OneTouch™ Mini III hard
drive was connected to the Wireless
USB device adapter and the following
scenarios were tested:
Wired vs. Wireless throughput
comparison. Moving 1GB of data (a
folder containing video files) from the
PC to the hard drive took 180 seconds
with the adapter set over the Wireless
USB link, vs. 48 seconds with wired
USB.
Link disconnect/connect. Exiting the
room with the laptop forced the
wireless link to disconnect. Then, after
entering the room, the link was automatically re-established and the disk was again available—without any user
involvement.
Automatic backup. The EasyManage™ software provided with the Maxtor disk, together with the OneTouch
backup, enabled entering the room with the laptop, automatically being connected to the hard disk drive, and
receiving a popup message on the need to backup a new file that was added to the PC but was not moved yet to
the hard disk.
In this usage scenario, the wireless connectivity enables a more user friendly backup process, which is initiated
automatically. In addition, backup is performed in small increments, each time new data is added to the PC,
without the need to physically connect to the hard disk each time.

USB HUB
USB hub testing was performed by attaching the device adapter to the upstream port of a Belkin 4-port hub, as can
be seen in the photos below.
Then, a multi-function printer and digital camera were attached to the hub. This provided wireless access to all
devices from a laptop. When existing and returning back to the room, all devices became available for access.
Performance was not affected by the existence of multiple devices, and depended on the specific type of device
connected. Since wireless connectivity was already established with the ‘wireless hub’, different devices could be
attached each time to the hub for wireless access.

DIGITAL STILL CAMERA (DSC)
A Sony Cyber-shot DSC-G1 digital camera
was placed in its cradle in one side of the
room. The Wireless USB device adapter
was then connected to the cradle.
Using a laptop with an adapter, photos
were uploaded from the camera.
Transferring 400 Mb took 140 seconds
over the wireless connection vs. 65
seconds with the cradle connected with
a USB cable.
EXTERNAL DVD/CD WRITER
With new laptops being sold without a
built-in CD/DVD, Wireless USB enables
placing the external CD/DVD player
anywhere in the room with wireless
access.
Testing was done with a Panasonic LF-
P968C portable DVD with read/write
operations performed wirelessly.
Reading 1GB of data from the player took
5:15 minutes with wireless, compared to
4 minutes with a wired USB connection.

IPOD
Using the adapter set, music files
or podcasts can be synchronized
wirelessly while the iPod is placed
away from the computer.
For instance, when the iPod is
placed in a docking station,
music/podcasts can be played from
speakers, while the iPod is charged.
At the same time, content can be
synchronized wirelessly with
iTunes installed on a PC placed at
the other side of the room.
To test iPod connectivity, 100 MB
of MP3 music files (23 songs) were
downloaded from the web to
iTunes and were synched to the
iPod.
CARD READER
With a card reader connected to
the device adapter, content can be
read or written from multiple
memory cards.
Reading 250 MB from an SD-card
placed in an Elcom MR-DU2A7BK
card reader took 111 seconds with
a wireless connection compared to
42.5 seconds with the wired
connection.

DIGITAL SLR CAMERA
With Wireless USB the camera can be placed on a shelf, away from the desk or
laptop, and be wirelessly accessed for downloading photos. In addition, Wireless
USB can be used for remote shooting. DSLR cameras like Canon or Nikon are
supplied with software that allows shooting remotely from the PC (see image on
right). The limitation of this scenario with standard USB is the short USB cable
connecting the PC to the camera.
By connecting the camera to the device adapter, shooting and photo transfer
can be done wirelessly, with the PC placed up to 10 meters from the camera.
To test this with Wireless USB, a Canon EOS KissX2/ 450D camera was placed on
a tripod in one side of a meeting room, connected to a device adapter. A laptop
with the PC adapter was then used in the other side of the room to wirelessly
take photos and instantly view the photo on the PC.
Viewing photos wirelessly is instant, without any noticeable difference between
wired and wireless. Downloading larger data chunks (200 MB) took 120 seconds
with a wireless connection and 98 seconds with a wired connection (translating
to 81% when comparing wireless data throughput to wired).

MULTI-DEVICE CONNECTIVITY
The adapter set supports simultaneous connectivity to up to 3 devices - for example, a printer, hard drive, and
camera. This requires each of the devices to be connected to a device adapter – as can be seen in photo below.
Printer
Camera
CD/DVD
In testing performed with 3 external disk drives connected simultaneously, each of the disks provided a throughput
of 35 Mbps, for a total of over 100 Mbps.
