Methods, systems, apparatuses, and computer program products are provided for detecting objects, including humans, using a mobile communications device. A communication space is scanned with a beam-shaped signal transmitted by a phased antenna array of the mobile communications device. Information is discerned from one or more attenuated signals received from the communication space based on the beam-shaped signal. The information is analyzed to determine an object in the communication space. Whether the object is likely at least a portion of a human is determined. A communication signal transmitted by the phased antenna array is modified in response to determining that the object is likely at least a portion of a human, and that the at least a portion of the human has a predetermined spatial relationship with the phased antenna array.
