Fortress ES-Series CLI Guide: Networking and Radio Configuration
61
You can configure BSSs on Radio 1 to accept connections only
from 802.11g devices (
Only11g
y
), instead of also accepting
802.11b device connections (
Only11g
n
, the default).
3.4.9.5 BSS Unicast Transmission Rate Settings
When a BSS is configured to use a
RateMode setting of
auto
(the default), the interface dynamically adjusts the bit rate at
which it transmits unicast data frames—throttling between the
configured
MaxRate and MinRate—to provide the optimal data
rate for the connection.
At a
RateMode setting of
fixed
, the BSS will use the
configured
MaxRate for all unicast transmissions and ignore
the configured
MinRate.
NOTE: Radio Band
settings are cov-
ered in Section 3.4.
Transmission rates are set in megabits per second (Mbps).
However, the rate as configured in MaxRate or MinRate is only
a hint to the radio as to what rate is the desired unicast
transmission rate. See Section 3.4.9.5.1 below for more
information.
MaxRate can be set only to a value greater than or equal to the
currently configured
MinRate, which likewise can be set only to
a value less than or equal to the configured
MaxRate. Usable
values for transmission rate settings depend on the
Band
setting for the radio on which the BSS is configured, as
indicated by the markers in Table 3.7.
The default
MaxRate and MinRate settings for a new BSS
define the largest range possible, as determined by the 802.11
standard in use by the radio on which you are configuring the
BSS. These defaults therefore also depend on the relevant
radio’s
Band setting.
The default
MaxRate depends on whether or not the radio is
using 802.11n: On a radio with an
802.11a
or
802.11g
Band
setting, the default
MaxRate is
54 Mbps
. On a radio using any of
the 802.11n settings in either frequency band, the default
MaxRate is
65 Mbps
.
The default
MinRate depends on the radio frequency band
without regard to 802.11n: On a radio using any 802.11g
Band
setting, including all 802.11ng options, the default
MinRate is
1
