5.6.2.5 802.11n
Properties of 802.11n
With the IEEE 802.11n standard, it is possible to put together individual data packets in one
larger data packet, the A-MPDU data packet. This achieves a higher data throughput.
On this page, you make the settings for the A-MPDU data packets. Some of the settings
depend on the set transmission standard and the selected channel width.
Description
The table has the following columns:
● Radio
Shows the available WLAN interfaces in this column.
● A-MPDU
Enables or disables the sending of A-MPDU data packets. If this check box is disabled,
A-MPDU data packets are received but not sent.
● A-MPDU Limit [Frames]
Specify the number of individual data packets grouped together in one AMPDU data
packet.
Range of values: 2 - 64 frames
● A-MPDU Limit [Bytes]
Specify the maximum size of the AMPDU data packet. Range of values: 1024 - 65535
bytes
● Guard Interval [ns](Only in access point mode)
Select the send pause that must be kept to between two transmitted OFDM symbols.
The following settings are possible. The selection depends on the selected transmission
standard.
– 400 (short): The send pause is 400 ns
– 800 (long): The send pause is 800 ns.
