Patent ID: 10034297

Abstract:
The present invention for reducing exposure of human to radio frequency radiation comprising a wireless device which comprises a high power radio frequency (HPRF) module, and a low power communications (LPC) module coupled to a switch and further coupled to a control unit and to the baseband unit or to the application processor of the hybrid wireless device; and a high power radio frequency-low power communications (HPRF-LPC) device which comprises a high power radio frequency (HPRF) module coupled to a processor and further coupled to a low power communications (LPC) module. Replication of the HPRF module in the wireless device and its function into the HPRF-LPC device enables communications between the HPRF-LPC device located at a distance away from the human head with a base station and reduces RF energy exposure. The present invention significantly reduces the RF exposure contributing to head SAR of 0.16 W/kg or lower averaged over one gram of tissue.
