Methods, systems, and devices for wireless communication are described. In some systems, a wireless device may detect, using a sensor at the wireless device, one or more locations at which human tissue may be present within a coverage area of the sensor. The wireless device may select, from a set of beams, a beam and a corresponding transmit power.
