WebWaveform Configuration. An HE SU packet is a full-band transmission to a single user. Configure transmit parameters for the HE SU format using a wlanHESUConfig object. Configure the object for a 20 MHz channel bandwidth, four transmit antennas, two space-time streams, 16-QAM rate-1/2 (MCS 3), and 4x HE-LTF compression mode.

Web• HE MU PPDU format: It is used when transmitting to one or more users. It is similar to SU format, except that an HE-SIG-B field is present. • HE trigger-based PPDU format: It is used for uplink OFDMA and/or MU-MIMO transmission. It carries a single transmission and is sent as an immediate response to a Trigger frame sent by the AP. Select the resource unit (RU) size for current user, which could be 26, 52, 106, 242, 484, 996, or 2*996 sub carriers.
