Advantages of Holographic Radio | Disadvantages of Holographic Radio
This page covers advantages and disadvantages of Holographic Radio System. It mentions benefits or advantages of Holographic Radio and drawbacks or disadvantages of Holographic Radio.
What is Holographic Radio ?
Like Light waves, holographic radio waves use EM (Electromagnetic) Waves. Hence it is similar to optical holography. It requires aperture antenna array in order to continuously receive the EM waves and to measure its wavefront phase.

As we know holography records EM field in the space based on interference principle of EM waves. The figure-1 depicts block diagram of holographic radio system. As shown it uses antenna array, modulator array, optical processor & Photonic AI and detector array.
The target EM field is reconstructed by information recorded with the help of interference oof reference/signal waves. It can be used to obtain RF (Radio Frequency) holography, spatial spectral holography, spatial wave field synthesis etc.
It can also regulate EM field of entire physical space precisely in fully closed loop.
