The spatial reuse is targetted to organise higher transmission density by lowering the transmission power when the sensitivity requirement is relaxed. An ill behaving AP can get benefit by misconfiguring SRG OBSS PD MIN value. In this case the non-AP STAs may transmit with full transmission power during the transmissions of the SRG OBSSs. The 802.11 should ensure fairness between STAs and not allow such behaviour. In worst case, this operation may be used against the WLAN, for instance It may be difficult to explain to the FCC and other regulators why WLAN allows such interfering transmissions and why it cannot control WLAN BSSs and STAs. Lack of control may prevent WLAN use in new spectrum and cause changes in the current regulation.
