282 Configuring the Wireless Array
• Channel number — If a channel number appears, then this channel is
already bonded to the listed channel.
• Off — Do not bond his channel to another channel.
• On — Bond this channel to an adjacent channel. The bonded channel
is selected automatically by the Array based on the Channel (Step 4).
The choice of banded channel is static — fixed once the selection is
made.
• +1 — Bond this channel to the next higher channel number. Auto
Channel bonding does not apply. This option is only available for
some of the channels, and only for 40MHz.
• -1 — Bond this channel to the next lower channel number. Auto
Channel bonding does not apply. This option is only available for
some of the channels, and only for 40MHz.
6. Click the Lock check box if you want to lock in your channel selection so
that an autochannel operation (see Advanced RF Settings) can’t change it.
7. In the Cell Size column, select auto to allow the optimal cell size to be
automatically computed (see also, “RF Power & Sensitivity” on page 323).
To set the cell size yourself, choose either small, medium, large, or max to
use 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 dBm (transmit) and Rx
dBm (receive) fields. The default is max. If you select a value other than
auto, the cell size will not be affected by cell size auto configuration. Note
that ultra low power Tx dBm settings are possible. Values from -15dB to
5dB are provided specifically to help in high density 2.4 GHz
environments.
When other Arrays are within listening range of this one, setting cell sizes
to Auto allows the Array to change cell sizes so that coverage between
cells is maintained. Each cell size is optimized to limit interference
between sectors of other Arrays on the same channel. This eliminates the
need for a network administrator to manually tune the size of each cell
when installing multiple Arrays. In the event that an Array or a radio
