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.
