802.11be Overview

The 802.11be is an Extremely High Throughput (EHT) enhancement of the 802.11ax standard (see 802.11ax Overview) to improve data throughput capabilities of 802.11 wireless LANs. The VSA software supports version D3.0 of the 802.11be standard.

802.11be demodulation has the following features:

802.11be signal bandwidths of 20 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second., 40 MHz, 80 MHz, 160 MHz and 320 MHz
Three configurations of MU Multi-user PPDUs: Single-user compressed (Compression Mode), multi-user MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. (Compression Mode), and multi-user OFDMA mode
Multi-user non-OFDMA (Compression Mode) signals up to 8x8 MIMO
Multi-user OFDMA signals up to 8x8 MIMO
Up to 4096-QAM Quadrature Amplitude Modulation modulation for data subcarriers
Autodetection of puncturing applied to frame

The VSA software supports decoding the EHT-SIG symbols to determine the frame type and allocations. Manually configuring the allocations for MU OFDMA and MU-MIMO multi-user, multiple input, multiple output: A technique here multiple STAs, each with potentially multiple antennas, transmit and/or receive independent data streams simultaneously. is also supported. Single-user MU PPDU PLCP Protocol data unit only supports decoding from SIG contents.

Compression Mode is a special case of OFDMA where instead of segmenting the frequency bandwidth into slices (RUs, or resource units), the entire bandwidth is allocated as a single RU and assigned to a single user (or multiple users, with different spatial streams for the MIMO case).
