Description
wireless clients.
Enabling this setting introduces randomness in the
beacon generation so that multiple APs on the
same channel do not send beacons at the same
time, which causes collisions over the air.
Work around a known issue on Cisco 7921G
telephones by specifying a cap for a radio's
maximum equivalent isotropic radiated power
(EIRP). When you enable this parameter, even if
the regulatory approved maximum for a given
channel is higher than this EIRP cap, the AP radio
using this profile will advertise only this capped
maximum EIRP in its radio beacons.
The cell size reduction feature allows you manage
dense deployments and to increase overall system
performance and capacity by shrinking an AP's
receive coverage area, thereby minimizing co-
channel interference and optimizing channel
reuse. This value should only be changed if the net-
work is experiencing performance issues. The pos-
sible range of values for this feature is 0-55 dB. The
default 0 dB reduction allows the radio to retain its
current default Rx sensitivity value.
Values from 1 dB - 55 dB reduce the power level
that the radio can hear by that amount. If you con-
figure this feature to use a non-default value, you
must also reduce the radio's transmission (Tx)
power to match its new received (Rx) power level.
Failure to match a device's Tx power level to its Rx
power level can result in a configuration that
allows the radio to send messages to a device that
it cannot hear.
Channel number for the AP 802.11a/802.11n
physical layer. The available channels depend on
the regulatory domain (country). Channel number
configuration options for 20 MHz and 40 MHz
modes:
num: Entering a channel number disables 40
l
MHz mode and activates 20 MHz mode for the
entered channel.
num+: Entering a channel number with a plus
l
(+) sign selects a primary and secondary
channel for
40 MHz mode. The number entered becomes
the primary channel and the secondary
channel is determined by increasing the
primary channel number by 4. Example: 157+
represents 157 as the primary channel and 161
as the secondary channel.
num-: Entering a channel number with a minus
l
(-) sign selects a primary and secondary
channel for
40 MHz mode. The number entered becomes
the primary channel and the secondary
