WIRELESS DEVICE PERFORMANCE OPTIMIZATION USING DYNAMIC POWER CONTROL - A simplified explanation of the abstract

  • This abstract for appeared for patent application number 18327595 Titled 'WIRELESS DEVICE PERFORMANCE OPTIMIZATION USING DYNAMIC POWER CONTROL'

Simplified Explanation

The abstract describes a method for monitoring and controlling the power usage of radio frequency (RF) emitting components in a mobile device to regulate the amount of RF exposure. By tracking and modifying power usage over time, the mobile device can control the average RF exposure within a specific time period. The mobile device periodically calculates updated averages of RF transmissions based on data received from its components, and compares these averages to predetermined power limits. If the averages exceed the limits, the mobile device can adjust the current transmissions of its radio transceivers and other RF emitting components accordingly.


Original Abstract Submitted

A dynamic specific absorption rate (SAR) may be implemented by monitoring and controlling power utilization of the various radio frequency (RF) emitting components over time within a mobile device. Power utilization may be tracked and modified to control the time-averaged RF exposure over a rolling time window. Periodically calculations of the updated rolling averages for RF transmissions may be performed based on the transmission data received from the mobile device components, and the continuously updated rolling averages of RF transmissions may be compared to time-average power utilization limits. Based on such comparisons, the mobile device may dynamically adjust the current transmissions of the radio transceivers and other RF emitting components on the mobile device.
