Radio frequency (RF) emitter detector

A method comprising:

• at an apparatus including a radio frequency (RF) detection device operable to detect energy carrying a communication signal to or from a personal communication device, the apparatus also including a peripheral interface connectable to a second device, wherein the second device is operably connectable to a personal communication device and includes a housing arranged to hold the personal communication device, and the apparatus, the second device, and the personal communication device are distinct devices:
• obtaining SIM information, via the peripheral interface and the second device upon the apparatus being attached to the housing of the second device, from the personal communication device;
• scanning an RF spectrum of the communication signal, received by the RF detection device in order to identify physical layer communication signal characteristics of communications associated with the personal communication device;
• decoding the communications associated with the personal communication device in accordance with the physical layer communication signal characteristics and the SIM information;
• determining whether or not abnormal activities exist in the communications;
• and
• generating a notification in accordance with a determination that abnormal activities exist in the identified physical layer communication signal characteristics of the communications, wherein the notification triggers interruption of the communication signal to or from the personal communication device upon identifying an RF energy burst through a comparison of energy detected by the RF detection device to a threshold.
