• The range of wireless devices can be affected by metal surfaces, solid high-density materials
and obstacles in the signal path.
Table “Radio Characteristics” lists the typical ranges when used indoors:
• In
Open Offi ce environments,
clients can “see” each other, i.e. there are no physical ob struc -
tions between them.
• In
Semi-open Offi ce environments
, work space is separated by room dividers; client cards
are at desktop level.
• In
Closed Offi ce environments,
workspace is separated by fl oor-to-ceiling brick walls.

NOTE: The range values listed in Table “Radio Char ac ter is tics” are typical distances as
measured at Buffalo Technology AirStation laboratories. These values are provided for your
guidance but may vary according to the actual radio conditions at the location where the
AirStation product is installed.
AirStation IEEE 802.11 Channel Sets
The range of the wireless signal is related to the Transmit Rate of the wireless communication.
Communications at a lower Transmit range may
travel longer distances.
