Compression Mode RU Settings (802.11n/ac/ax/be)

For 802.11ax and 802.11be multi-user case scenarios, different users are designated to different spatial time streams when the compression mode is on (Sig B Compression Field selected).

802.11ax/be Standards (Except 802.11ax 80+80 MHz)

The following rules apply to all 802.11ax/be standards except 802.11ax 80+80 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second.:

The number of users never exceeds the number of input channels.
The number of spatial time streams of each user never exceeds 4.
The sum of the number of spatial time streams of each user never exceeds the number of input channels.

Compression Mode RU Settings is comprised of a User Number and an Edit RU button. Clicking Edit RU opens a Multi-User Settings Editor that is specific to compression mode.

User Number - Displays the configured User Count.

Edit RU... - Opens a Multi-User Settings Editor that is specific to non-compression mode.

802.11ax 80+80 MHz Standard

The 802.11ax 80+80 MHz standard only supports one measurement channel per each 80 MHz segment. Therefore, the number of transmit chains (Ntx) is fixed to 1 and only one user exists in each 80 MHz segment. Since there are two single-user segments, the Multi-User Settings Editor does not apply and is replaced with a simplified Seg n Settings dialog for setting the MCS modulation and coding scheme for each segment.
