Solution Approach 1:

A radio wave propagation controlling apparatus is introduced as an intermediary device between communication apparatuses. This apparatus includes a reflection controlling section that reflects radio waves toward intended receivers, and a refraction controlling section that refracts radio waves to control their propagation paths. By using this intermediary apparatus, the patent enables multiple communication apparatuses to share wireless resources while actively controlling and reducing radio wave interference through physical manipulation of wave propagation.

Solution Approach 1:

The radio wave propagation controlling apparatus is divided into distinct functional sections: a reflection controlling section and a refraction controlling section. Each section independently controls specific aspects of radio wave propagation. This segmentation allows the complex task of interference control to be distributed across specialized subsystems, improving communication quality while managing device complexity through modular functional division.
