Parameters
1x1: Sends and receives signals through one spatial stream.
2x2: Sends and receives signals through two spatial streams.
Usage guidelines
MIMO enables a radio to send and receive wireless signals through multiple spatial streams. This
improves system capacity and spectrum usage without requiring higher bandwidth.
Examples
# Set the MIMO mode to 2x2.
<Sysname> system-view
[Sysname] interface wlan-radio 0/1
[Sysname-WLAN-Radio0/1] mimo 2x2
[Sysname-WLAN-Radio0/1] undo mimo
preamble
Use preamble to set the preamble type.
Use undo preamble to restore the default.
Syntax
preamble { long | short }
undo preamble
Default
The short preamble is used.

Parameters
long: Specifies a long preamble. A long preamble ensures compatibility with all wireless devices that
use an earlier standard than 802.11n.
short: Specifies a short preamble. A short preamble can improve network performance.
Usage guidelines
This command is applicable only to 802.11b, 802.11g, and 802.11gn radios.
A preamble is a set of bits in a packet header to synchronize transmission signals between sender
and receiver.
Examples
# Set the preamble type to long.
