Abstract
A communication device includes a processor subsystem that is in communication with a communication module, which is communicatively coupled to an antenna array to transmit and receive signals. The processor subsystem executes a near-field detection application to perform a method including transmitting, via the antenna array, a signal that is swept across a range of frequencies and receiving any back-scattered signals in the range of frequencies. The method includes determining whether a near-field obstruction exists based on characteristics of the received back-scattered signals. In response to determining that a near-field obstruction exists, the method includes triggering the processor subsystem to perform one or more responsive operations on the communication device. The operations include a selected one of: (i) altering a transmission beam transmitted by the communication device; and (ii) triggering an application to execute on the communication device, the application intended to interact with a user of the communication device.
