parameter should correspond with the actual increase of and more dense
placement of your Base Stations.
The examples listed on the following pages will illustrate the effect of the
various Distance between APs configurations.
In Figure 6-30 you see the standard configuration of networks, where
Distance
between APs
parameter has been set to Large.
! The receiver sensitivity in this mode causes the wireless radio device to
defer transmissions for all messages that it senses within its range (identified
by the colored circles).
! Roaming stations in a specific cell will remain connected to the servicing
Base Station until they exit the wireless cell.
This setting provides you with the maximum radio range possible with the
minimum number of Base Stations to cover the wireless network area.
Figure 6-30: Large Distance between APs
The examples in Figure 6-31 and Figure 6-32 show you the effect of changing
the Distance between APs parameter. Although the absolute range of the
wireless radio is still the same, the Distance between APs setting has virtually
reduced the range of the wireless cell by applying different levels of receiver
sensitivity:
! The absolute range of the radio signal from the Base Stations is identified by
the gray-dotted circles
! The reduced virtual range is identified by the colored areas.
With the new settings for the Distance between APs parameter, stations will
only defer for radio signals that are received at a level that is equal or higher to
the average signal as applicable in the colored areas. Messages with a lower
signal level are considered to be traffic belonging to another cell, so will be
ignored when the station determines whether it can start transmitting.
