Solution Approach 1:

The system dynamically adjusts transmission power based on real-time proximity sensing data and calculated power density values. Instead of using fixed power management thresholds, the system continuously monitors environmental conditions and adapts transmission parameters to maintain both high productivity and sufficient compliance margins through dynamic control

Inventive Principle:

Solution Approach 2:

The system implements a feedback mechanism where power density values are calculated based on transmission power and proximity distance, compared against regulatory limits, and used to adjust subsequent transmission power decisions. This closed-loop feedback ensures that the system maintains optimal performance while staying within regulatory boundaries
