PHY level protection: Mixed Mode Format protection (also known as L-SIG TXOP Protection): In mixed mode, each 802.11n transmission is always embedded in an 802.11a or 802.11g transmission. For 20 MHz transmissions, this embedding takes care of the protection with 802.11a and 802.11g. However, 802.11b devices still need CTS protection.

c) L-SIG TXOP protection (don't worry, we'll cover it in Part II) d) Using a mixed format preamble, transmit first a PPDU that requires a response that is sent as a non-HT frame or non-HT duplicate frame. The remaining TXOP following the first PPDU exchange may contain HT …

"L-SIG TXOP Protection should not be used and the implementers of L-SIG TXOP Protection are advised to include a NAV based fallback mechanism, if it is determined that the mechanism fails to effectively suppress non-HT transmissions. How this is determined is outside the scope of this standard." This is a hint that it might not work.

"An HT STA that asserted the L-SIG TXOP Protection Support field upon association that receives an L-SIG protected PPDU containing valid L-SIG Parity and HT-SIG CRC fields and that contains no valid MPDU from which a Duration/ID value can be determined shall, at the end of the PPDU, update its NAV to a value equal to L-SIG duration - HT-SIG ...

Indicates whether all HT STA in the BSS support L-SIG TXOP protection. 0 – one or more HT STA in the BSS do not support L-SIG TXOP protection 1 – all HT STA in the BSS support L-SIG TXOP protection. L-SIG TXOP protection is an optional Physical layer protection mechanism, which uses the L-SIG (Legacy Signal) fi eld in the HT mixed PPDU ...

An L-SIG TXOP protected frame exchange sequence always begins with an RTS/CTS or a CTS-to-Self. D. L-SIG TXOP Protection is specified for the purpose of protecting OFDM (802.11a/g) and HT-OFDM (802.11n) transmissions from HR/DSSS stations.

May 10, 2017 · I am running the following hostapd configuration on a WRT1900ACSv2. The configuration below works fine on other models with, for instance ATH9k wireless chips, however the 88W8864 in the WRT1900ACSv2 fails to add the Mobility Domain Information Element (MDIE) to the Beacon frame when it is configured via hostapd.
