AirStation IEEE 802.11 Channels 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.
NOTE:
The range values listed in Table “Radio Characteristics” on page A-3 are typical distances as measured
at the 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
will be installed.

• The range of your wireless devices can be affected when the WLI-USB-L11G is 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 “Radio Characteristics” on page A-3 lists the typical ranges
when used indoors in “office environments” as 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.
