•The range of wireless devices can be affected by metal surfaces, solid high-density materials and obstacles in the signal path.

•In Open Office environments, clients can “see” each other, i.e. there are no physical obstructions between them.

•In Semi-open Office environments, work space is separated by room dividers; client cards are at desktop level.

•In Closed Office environments, workspace is separated by floor-to-ceiling brick walls.

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. Communications at a lower Transmit range may travel longer distances.
