MPDU - 802.11be

MPDU Configuration

MPDU Index

Displays the index for each MPDU. This cell cannot be edited.

A-MPDU Subframe Length

This is information indicating the number of octets in current A-MPDU subframe, which is comprised of MPDU and Padded MPDU Delimiters. It's only available when the Aggregated MPDU is on. If the current MPDU is not the last one, its length can not be shorther than Minimum MPDU Start Spacing, otherwise, MDPU delimiters will be padded after current MPDU. It current MPDU is the last one, its A-MPDU Subframe Length is equal to its MPDU Length plus the length of one MPDU Delimiter(4 octets).

MPDU Length

Displays the number of octets in current MPDU, which is comprised of MSDU, MAC Header and MAC FCS.

Prior to N7617B version 1.12.0.0, this was named MAC Frame Length.

Data Type

Use this cell to select the payload data source. The user data of the frame can contain the following data:

All 0s

PN9

PN15

User file

The user file must be in binary form. The least significant bit (LSB) of the first byte in the user data file will be the first bit of the user payload; the LSB of the second byte in the user file will be the ninth bit of the user payload, and so on. If User file is selected as the Data Type, the value displayed in the Data Length field will be equal to the length of the user's data file, up to the maximum data length.

PN9 Seed

Range: 0 to 511

Default: 511

Specify a seed in decimal format to generate a PN9 data sequence. The LSB of the seed comes out first. For example, if you enter a seed value of 10 (1010 in binary), the first 9 bits of the PN9 sequence are 0 1 0 1 0 0 0 0 0, with an increasing index from left to right. For more information, see PN Sequence Generation.

PN15 Seed

Range: 0 to 32767

Default: 32767

Specify a seed in decimal format to generate a PN15 data sequence. The LSB of the seed comes out first. For example, if you enter a seed value of 10 (1010 in binary), the first 15 bits of the PN15 sequence are 0 1 0 1 0 0 0 0 0 0 0 0 0 0 0, with an increasing index from left to right. For more information, see PN Sequence Generation.

Data Length

Use this cell to set the number of data bytes in a frame. The value is limited by MPDU Length.

User File

Click the button in this cell to select a user file as the data source.

The user file must be in binary form. The least significant bit (LSB) of the first byte in the user data file will be the first bit of the user payload; the LSB of the second byte in the user file will be the ninth bit of the user payload, and so on. If User file is selected as the Data Type, the value displayed in the Data Length field will be equal to the length of the user's data file, up to the maximum data length.

This field is visible only if we select User File in the Data Type drop-down.

User File Length

This cell displays the number of data bytes in the user file when it is selected as the payload data source.

This field is visible only if we select User File in the Data Type drop-down.

MAC Header

Click the button in this cell to open the MAC Header Dialog (see the dialogs below), which enables or disables pre-pending the MAC header to the data payload. You can select ClosedGeneral, ClosedRTS, ClosedCTS, or ClosedACK format by clicking the down arrow in the top right corner of the Mac Header Dialog. You can set the desired data in each of the individual fields for each format. You can also disable these fields if the data is no longer desired by clearing the Mac Header (hex) checkbox.

MAC FCS

Enable/disable the appending of a MAC FCS check sequence to the data payload.
