The range of the wireless signal is related to the Transmit Rate of the
wireless communication. Communications at lower Transmit range will
travel larger distances. The range values listed above are typical distances
as measured under controlled conditions. These values may vary according
to the actual radio conditions at the location where the 802.11b and 11g AP
Cards 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.
The listed ranges are typical values when used indoors in "office environ-
ments" that can be described as follows:
In Open Office environments, antennas can "see" each other, that is,
■
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.
Auto Channel Selection. When inserted into the HP ProCurve Wireless
Access Point 520wl, the 802.11b and 11g AP Card will use the factory-set
default channel (channel 10, printed in bold), unless the LAN
Administrator selected a different channel when configuring the access
point device.
