An apparatus has a wireless local area network (WLAN) transceiver and one or more sensors. The sensors are monitored. From time to time, a mitigation level applicable to the apparatus is determined as a function of output from the one or more sensors. The mitigation level is one of multiple mitigation levels, each mitigation level corresponding to a set of configuration changes for a Media Access Control (MAC) layer of the WLAN transceiver. Responsive to determining that the applicable mitigation level has increased from a most recent previously determined mitigation level, the MAC layer is configured to effect a decrease in a transmit duty cycle of the WLAN transceiver. Responsive to determining that the applicable mitigation level has decreased from a most recent previously determined mitigation level, the MAC layer is configured to effect an increase in the transmit duty cycle of the WLAN transceiver.
