An example method may include receiving, by a serving base station of the device, a first set of information associated with data communications of a device utilizing a cellular network. The method may further include determining the device is an interfering device based on the first set of information associated with the data communication substantially corresponding with an interfering device profile, and in response tracking the device. During the tracking of the device, a second set of information associated with the data communications from the device may be obtained, and an interfering device type of the device may be determined based on the second set of information. An action may be performed on the interfering device based on its interfering device type. ## Claims ### Claim 1 A method for identifying a device as a source of radio frequency interference in a cellular network, the method comprising: receiving, from a base station included in the cellular network, a first set of information corresponding with data communications between the device and the cellular network;
