Abstract:
1. A method for controlling radiation of radio frequency (RF) energy by a wireless communication device that includes a transmitter and an antenna, the method performed by the wireless communication device and comprising the steps of: producing radiated RF energy by the wireless communication device; sensing, by a vector field sensor that is positioned within a portion of the wireless communication device that corresponds to a Hearing Aid Compatibility (HAC) grid, an intensity of a vector field within the portion of the device that corresponds to a particular measurement area of the HAC grid within which an intensity measurement taken during device testing was highest, when compared with intensity measurements taken during the device testing within measurement areas other than the particular measurement area, wherein the vector field results from the radiated RF energy; determining whether a value representing the intensity is greater than a first threshold; and when the value is greater than the first threshold, decreasing the radiated RF energy produced by the wireless communication device.
