HE MU-MIMO vs VHT MU-MIMO
The 6th video in the series of the 802.11ax training videos. In this video I explain the difference between SU-MIMO and MU-MIMO and how MU-MIMO is done differently in the 802.11ax standard compared to legacy MU-MIMO.
OFDMA In Action
The 5th video in the series of the 802.11ax training videos. In this video I explain the process that APs and STAs have to go through to complete an OFDMA transmission in the 802.11ax standard.
