What is Reconfigurable Intelligent Surface (RIS)
Y.RIS
A Reconfigurable Intelligent Surface (RIS), is a novel technology in the field of wireless communications and signal processing. It involves deploying a planar array of passive elements, such as antennas or metamaterial-based units, that can be electronically controlled to manipulate the characteristics of wireless signals in real-time.

1
Improve the coverage and signal strength in areas with poor reception
2
Manage interference and mitigate signal blockages. By shaping the reflected signals, it’s possible to create nulls or reduce unwanted signal interference in certain directions.
3
Add a layer of security and privacy to wireless communications. By dynamically changing the signal’s propagation characteristics, it can make it more challenging for eavesdroppers to intercept or decode the transmitted information.
4
By optimizing signal paths, RIS can potentially reduce the power needed for communication. This is especially relevant for battery-constrained devices.
5
Improve spectral efficiency by optimizing the use of available frequency bands.
6
Enable advanced beamforming techniques that allow the creation of customized signal patterns for specific users or areas.
