• The range of wireless devices can be affected by metal surfaces, solid high-density materials and obstacles
in the signal path.
■ Note:
The range values listed in Table “Radio Characteristics” 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. Communica-
tions at a lower Transmit range may travel longer distances.
