Configuring MIMO
Operation for Mobile
Applications
/interface/wifi-<n>-<m>/set mimo-mode {1x1|1x2|2x2|2x3|3x3}
This command configures the Multiple-Input and Multiple-Output (MIMO)
antenna settings for mobility applications using 802.11n radios, such as those
for the BelAir20M. In such applications. the 5.8 GHz radio must operate with a
MIMO setting of 1x1 while the 2.4 GHz access radio must operate with a
MIMO setting of 2x2.
Use this command to adjust the MIMO setting of each radio interface as
required. The supported modes vary depending on the type of radios in your
unit, as follows:
• HTM and DRUE radios support only 1x1, 2x2 and 3x3 modes
• HTME radios support only 1x1 and 2x2 modes
• DRU radios support only 1x1, 1x2, 2x2 and 2x3 modes
Example
/interface/wifi-1-1# set mimo-mode 1x1
/interface/wifi-1-2# set mimo-mode 2x2
The previous commands apply to a BelAir20M where interface wifi-1-1 is for a
5.8 GHz radio while interface wifi-1-2 is for a 2.4 GHz access radio.
Configuring and
Enabling Mobile
Backhaul Mesh Links
/interface/wifi-<n>-<m>/set backhaul mobile
([identifier <link-id>] [role {bs|ss}]
[privacy {{enabled key <pre_shared_key>}|disabled}]
[admin-state {enable|disable}])
This command configures the mobile backhaul link identifier, the role of the
node and backhaul privacy. It also lets you enable or disable mobile backhaul
mesh functionality. The default setting is
disable
.
The mobile backhaul link identifier identifies all members of a particular mobile
backhaul mesh. The
<link_id>
parameter is case sensitive and can be up to
32 alphanumeric characters. A suitable link identifier is short phrase unique to
the mobile backhaul mesh.
When configuring a particular mobile backhaul mesh, you must configure all
members to have:
• the same channel. Refer to
“Operating Channel” on page 74
for the
appropriate command
• the same mobile link identifier
• the same privacy settings
