80 Configuring the XS-3900
Procedure for Manually Configuring IAPs (Radios)
1. In the Enabled column, check the box of a corresponding radio to enable
the radio, or uncheck the box if you want to disable the radio.
2. In the Mode column, select the wireless mode for this
radio from the choices available in the pull-down
menu (either .11a or .11b/g).
3. In the Channel column, select the channel you want
this radio to use from the channels available in the
pull-down list.
The sample pull-down list shown here is for the abg2
radio with its mode set to .11b/g. Any channels
appearing in the list that are shown in RED are not
recommended.
4. In the Cell Size column, choose either Small,
Medium, or Large to define the desired pre-
configured cell size, or choose Manual to define the
wireless cell size manually. If you choose Manual,
you must specify the transmit and receive power—in dB—in the Tx
Power dB (transmit) and Rx dB (receive) fields.
The number of users and their applications are major drivers of
bandwidth requirements. The network architect must account for the
number of users within the XS-3900’s cell diameter.
In a large office, or where user density is high, you should choose Small
cells to achieve a higher data rate, since walls and other objects will not
define the cells naturally.
For additional information about cell sizes, go to “Coverage and Capacity
Planning” on page 21.
