INTRODUCTION
All ParkerVision Wireless products are designed

fully compliant with IEEE 802.11b standards and are
optimized to provide maximum possible speed and
bandwidth through your Internet connection for fastest
uploads and downloads.
The distance capabilities of your wireless network
equipment directly affect your signal quality. Distance
capabilities are usually stated in terms of outdoor, open
fi eld reach. However, this reach is greatly diminished
indoors by walls, doors, construction techniques and
appliances that may block the radio signal. A wireless
network card that tests outdoors at 200 feet could, in an
indoor environment, provide 20 feet in one direction and
as little as 5 or 10 feet in another direction. Factors such
as building materials, fl oor plans and furnishings can
greatly impact the signal range, quality and rate of data
transmission. The extent to which your signal is affected
varies greatly depending on your environment.
Wireless network products powered by D2D technology
will provide better performance than other products
because they can achieve open fi eld distances of up
to one mile, (when a D2D enabled card is used in
conjunction with a D2D enabled base station). The D2D
card alone provides 3 to 7 times the distance of other
leading brands. This is suffi cient to reach all rooms in
most homes or small offi ces.
