In some aspects, an interference packet transmitted by an interfering device of a wireless environment is received via multiple antennas of a device. Based on the interference packet, an interference channel that describes interference in the wireless environment is estimated. The device then receives an intended packet through the wireless environment in which the interfering device is operating. At least a portion of interference received with the intended packet, such as interference caused by other interfering packets, is cancelled using the interference channel By so doing, a receiver may reduce effects of interfering packets or signals of the wireless environment to improve receive performance (e.g., bit-error rate) for packets that are intended for reception by the device. |

The threshold may be associated with a measurement event configured by the wireless network, and the device may use the new value for the threshold when performing measurements on wireless channel conditions of the wireless network. When adjusting the threshold, the device may adjust the threshold once per application session of the application, and/or once per current radio resource control (RRC) connection before the wireless network releases the current RRC connection. Furthermore, the device may adjust the threshold only if the network-configured value associated with the measurement event is greater than a specified threshold value. |

A timestamp, source internet protocol (IP) address, and fully qualified domain name (FQDN) value are extracted from each DNS query event record. Each FQDN value is classified to generate corresponding key-value pairs. For each source IP address, key-value pairs during a period of time are counted. It is determined if a FQDN value or key-value pair value indicates anomalous behavior. One or more alert messages are generated if anomalous behavior is determined. |
