Radio Characteristics
A-6 WaveLAN/IEEE Turbo 11 Mb PC Card
The range of the wireless signal is related to the Transmit Rate of
the wireless communication. Communications at lower Transmit
range may travel larger distances.
NOTE:
The range values listed in Table A-4 on page A-5 are
typical distances as measured at the Lucent Technologies
WaveLAN laboratories. These values may provide a rule
of thumb and may vary according to the actual radio
conditions at the location where the WaveLAN product will
be installed.
■ The range of your wireless devices can be affected
when the antennas are placed near metal surfaces
and solid high-density materials.
■ Range is also impacted due to “obstacles” in the signal
path of the radio that may either absorb or reflect the
radio signal.
Table A-4 lists the typical ranges when used indoors in “office
environments” that can be described as follows:
■ In Open Office environments, antennas can “see” each
other, i.e. there are no physical obstructions between them.
■ In Semi-open Office environments, work space is divided by
shoulder-height, hollow wall elements; antennas are at
desktop level.
■ In Closed Office environments, work space is separated by
floor-to-ceiling brick walls.
If you intend using the WaveLAN PC Card as part of an outdoor
antenna installation, the range of the outdoor antenna installations
will be related to:
■ Type of outdoor antennas connected to the WaveLAN card.
■ Length of antenna cables.
■ Clearance of the radio signal path.
