INTRODUCTION
All ParkerVision Wireless products are designed and 
manufactured by Direct2Data Technologies. Products 
are 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.
