This page explores the advantages and disadvantages of Holographic Radio Systems, outlining both the benefits and drawbacks.

What is Holographic Radio?

Introduction:

Holographic radio, much like optical holography which uses light waves, leverages Electromagnetic (EM) Waves. In essence, it mirrors the principles of optical holography. To function, it needs an aperture antenna array capable of continuously receiving EM waves and measuring the phase of their wavefront.

As we know, holography records the EM field in space using the interference principle of EM waves. Figure 1 (refer to the image above) illustrates a block diagram of a holographic radio system. It comprises an antenna array, modulator array, optical processor & Photonic AI, and a detector array. The target EM field is reconstructed using information recorded through the interference of reference/signal waves.

This technology enables RF (Radio Frequency) holography, spatial spectral holography, spatial wave field synthesis, and more. Furthermore, it can precisely regulate the EM field of an entire physical space in a fully closed loop.

Benefits or Advantages of Holographic Radio

Here are the key benefits of Holographic Radio:

  • Increased Spatial Multiplexing Efficiency: Holographic radio significantly boosts the efficiency of spatial multiplexing.
  • Improved Spectral Efficiency: Spectral efficiency sees a considerable improvement.
  • Enhanced Network Capacity: Network capacity experiences a boost.
  • RF Convergence: It facilitates the RF convergence of imaging, positioning, and wireless communications.

Drawbacks or Disadvantages of Holographic Radio

Despite its potential, holographic radio faces several challenges:

  • AI Infrastructure Requirements: It demands a low-latency, highly reliable, and scalable AI architecture to process the massive data generated by the holographic radio system.
