7. The Bond field works together with the Channel selected above. (For
802.11n IAPs, it also obeys the bonding options selected on the Global
Settings .11n page.) Also see the discussion in “80 MHz and 160 MHz
Channel Widths (Bonding)” on page 43. Bonding is available on all
Arrays, including two-radio models. For 802.11n, two 20MHz channels
may be bonded to create one 40 MHz channel with double the data rate.
802.11ac offers an additional option to bond four 20MHz channels to
create one 80MHz channel with four times the data rate.
• 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.
• 40 MHz — Bond this channel to an adjacent channel. The bonded
channel is selected automatically by the Array based on the
Channel (Step 5). The choice of banded channel is static — fixed once
the selection is made.
• 80 MHz — Bond this channel to three adjacent channels. The bonded
channels are selected automatically by the Array based on the
Channel (Step 5). The choice of bonded channels is static — fixed once
the selection is made.
The top line for the IAP will show the channels that have been assigned
based on the width of the bond.
8. In the Cell Size field, select auto to allow the optimal cell size to be
automatically computed (see also, “RF Power & Sensitivity” on page 336).
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 Power (transmit) and Rx
Threshold (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.
