Description
Select the MU MIMO check box to enable multi-user MIMO
(MU-MIMO).
By default, the MU MIMO check box is cleared and MU-MIMO is
disabled.
802.11ac Wave 2 supports MU-MIMO, which enables multiple users to
receive data from the access point simultaneously using the same
channel. With MU-MIMO, an access point such as the WAC740, which
is capable of 802.11ac Wave 2, can transmit to multiple clients
simultaneously using the same channel. MU-MIMO is used in the
downstream direction and requires both the access point and the WiFi
clients to be capable of 802.11ac Wave 2.
The selections that are available depend on the selected radio mode.
From the menu select the wireless mode:
• 802.11b/bg/ng mode:
- 802.11b.
- 802.11bg.
- 802.11ng. This is the default setting.
• 802.11a/na/ac mode:
- 802.1a.
- 802.11na.
- 802.1na/ac. This is the default setting.
Note: If you select 802.11bg or 802.11b mode, both 802.11n- and
802.11g-compliant devices can connect to the access points. However,
if you select 802.11ng mode, 802.11b-compliant devices cannot
connect.
By default, the transmit data rate of the WiFi network is set to Best. You
cannot manually change the transmit data rate.
Note: For 802.11na and 802.11ac devices, the page shows separate
data rates with the default setting Best.
From the menu, select the channel width:
• 20 MHz Static. This is the default setting if the selection from the
Wireless Mode menu is 802.11ng.
• 20/40 MHz Dynamic.
• 20/40/80 MHz Dynamic. This is the default setting if the selection
from the Wireless Mode menu is 802.1na/ac. This setting is an
option for 802.11na/ac devices only and does not apply to 802.11ng
devices.
A wider channel improves the performance, but some legacy devices
can operate only with a 20 MHz channel width.
From the menu, select a value that protects transmissions from
interference.
A shorter guard interval improves performance, but some legacy
devices can operate only with a long guard interval.
