Kevin, it’s not about the energy.
It’s about the way a signal changes over time (modulation)
The way the field is oriented in space (polarization)
The way power is concentrated in short bursts (PAPR)
The way energy is spread across frequencies (bandwidth)
The way noise raises the floor, lowering SNR (signal-to-noise ratio)
The way beams are shaped in space (beamforming / spatial structure)
The way signals mix inside nonlinear tissues, creating new intermodulation frequencies
The WAVEFORM structure.
