Reconfigurable Intelligent Surface

Reconfigurable Intelligent Surface (RIS)


  • A Reconfigurable Intelligent Surface (RIS) is a technology that improves wireless communication performance by manipulating electromagnetic waves using individually controllable metasurfaces.
  • By adjusting the phase and characteristics of received waves, RIS can route signals around obstacles, improve coverage, and increase data rates—making it an energy-efficient solution for future networks such as B5G and 6G.
  • Considering its potential applications and benefits in wireless networks, RIS is regarded as one of the most promising technologies for next-generation communication infrastructure and is expanding into various solution forms.

Key Features and Operating Principles
Key Features and Operating Principles
  • Wave control: While conventional walls or surfaces reflect or transmit radio waves randomly, RIS uses numerous small antennas or meta-material structures attached to its surface to control electromagnetic properties such as reflection, transmission, scattering, and absorption in a desired direction.
  • Intelligent environment: Unlike repeaters that simply amplify signals, RIS intelligently senses and controls the surrounding wireless environment to optimize signal strength and quality.
  • Low power and low cost: RIS can operate passively or with ultra-low power without high-power transceivers. Compared to conventional infrastructure, it offers higher energy efficiency and lower deployment cost.

The Role of RIS in Communication Environments
RIS role in communication environment
  • Coverage extension and shadow-area mitigation: High-frequency bands (e.g., 6G mmWave) are vulnerable to obstacles. Installing RIS on building exteriors or indoor windows can reflect or transmit waves to enable reliable connectivity even in hard-to-reach areas.
  • Enhanced beamforming: RIS supports beamforming by focusing signals toward specific users, improving communication efficiency.
  • Interference reduction: By controlling unwanted signal paths, RIS reduces interference and improves overall communication quality.

Problems We Aim to Solve with RIS

  • Improving coverage limitations and radio reach: Signals can weaken significantly or create dead zones due to buildings, walls, and other obstacles.
    RIS leverages beamforming to guide and reflect signals toward hard-to-reach areas, expanding coverage.
  • Increasing capacity and spectral efficiency: Spectrum resources are limited, and channel conditions can change, causing unstable signal quality.
    RIS dynamically adjusts propagation paths between user devices and base stations to reduce interference and improve throughput and spectral efficiency.
  • Improving energy efficiency: Without deploying high-power transmitters or numerous repeaters, RIS can reduce power consumption by controlling phase and amplitude on reflective surfaces.
    This improves system-level energy efficiency and contributes to greener communications.
  • Enhancing signal quality and reliability: By optimizing propagation characteristics with reconfigurable metasurfaces, RIS can provide high-quality signals even under severe channel variations.
    This improves QoE and supports next-generation 6G and ultra-high-speed wireless networks.
