802.11 b/g/n mode For radio1, specify B, G and N, B and G, G Only, B only or N Only to
define whether the 802.11b/g/n radio transmits in the 2.4 Ghz
band exclusively for 802.11b (legacy) clients or transmits in the
2.4 Ghz band for 802.11g/n clients. Selecting b and g enables the
Brocade Mobility 7131N-FGR Access Point to transmit to both b
and g clients if legacy clients (802.11b) partially comprise the
network. Select accordingly based on the MU requirements of the
network.
The rates for the access point’s 2.4 GHz radio are as follows:
B, G and N - Allows only basic rates (default setting).
B and G - Allows 11b basic rates. Does not allow MCS rates.
G and N - Requires basic rates (either 6, 12, 24 or 1, 2, 5.5, 11, 6,
12, 24).
G Only - Requires one 11g basic rate. Does not allow MCS rates.
B Only - Allows for 11b rates only. Does not allow G or N rates.
N Only - Requires basic MCS rates.
Note: If the mode is B and G, the Channel Width option is not
available, and a Secondary Channel cannot be defined.
For the 5 GHz radio, specify A and N, A Only or N Only to define
whether the 802.11a/n radio transmits in the 5 Ghz band
exclusively for 802.11a clients, 802.11n clients or transmits in the
5 Ghz band for both 802.11a/n clients.
A Only - Allows 11a rates.
N Only - Requires basic MCS rates.
A and N - Allows only 11a basic rates (default setting).
Channel Width Select the Channel Width (MHz) from the drop-down menu. The AP
radio can support 20 and 40 MHz channel widths. 20 MHz is the
default setting for the 2.4 GHz radio. 20/40 MHz operation (the
default setting for the 5 GHz radio) allows the access point to
receive packets from clients using 20 MHz of bandwidth while
transmitting a packet using 40 MHz bandwidth. This mode is
supported for 11n users on both the 2.4 and 5 GHz radios. If an
11n user selects two channels (a Primary and Secondary
channel), the system is configured for dynamic 20/40 operation.
When 20/40 is selected, clients can take advantage of “wider
channels.” 802.11n clients experience improved throughput using
40 MHz while legacy clients (either 802.11a or 802.11b/g
depending on the radio selected) can still be serviced without
interruption using 20 MHz. Define a value as needed depending
on the channel used. This field is not available when B and G is
selected as the 802.11 b/g/n mode.
