About YTTEK Technology

As a leader in software-defined radio technology, YTTEK is committed to delivering comprehensive wireless communication solutions that empower engineers to achieve the highest levels of reliability and performance while meeting demand faster than ever.

Breaking down borders and synchronizing with cutting-edge technologies golbally.

YTTEK collaborates with DIREK, a UK-based smart building management solutions provider, and the University of Surrey to integrate Y.RIS with AI-assisted tracking technology. This integration automates Y.RIS beam direction settings to track moving individuals, accelerates the adoption and promotion of 5G mmWave (millimeter-wave) and future 6G THz (terahertz) wide-band applications.

Demonstration of Y.RIS integrated with AI-assisted tracking technology.

Considering the signal-blocking challenges encountered in high-frequency wireless transmission for 5G mmWave and future B5G/6G networks, RIS (reconfigurable intelligent surface) is considered an energy-efficient and cost-effective solution to eliminate signal dead zones. YTTEK’s Y.RIS utilizes advanced liquid crystal techniques to design metasurface antenna subunits (Unit Cells) on glass surfaces. Through precise phase control achieved by applying voltage to the electrodes at both ends of the liquid crystal, the electric field and polarization direction are altered, subsequently adjusting its effective dielectric constant (permittivity) and modifying the signal phase accordingly. The flexibility of the liquid crystal panel allows signals to be reflected in various directions, making it an advanced solution in RIS.

YTTEK’s key technology for liquid crystal RIS, combined with DIREK and the University of Surrey’s AI-assisted tracking technology, provides Y.RIS with optimal beamwidth and reflection angle settings, enabling network-intelligent automatic configuration. This allows Y.RIS to accurately reflect signals to the location of individuals through AI-assisted tracking, automatically adjust settings based on different locations or indoor layouts, and enhance Y.RIS’s energy efficiency.

This collaboration further advances the application of B5G/6G and 5G mmWave private networks. For example, in the context of Industry 4.0 smart factories, where large equipment often causes signal dead zones, and numerous AGVs (Automated Guided Vehicles) move around. By strategically deploying 5G mmWave base stations in conjunction with Y.RIS in corners or areas obstructed by mechanical equipment and leveraging AI tracking technology to dynamically reflect signals to moving AGVs, we can achieve a holistic solution for 5G-enabled smart factories.

This deployment method also potentially creates a more cost-effective and energy-efficient communication system. For example, to set up a smart factory, 5 small cells are required, with 2 of them dedicated to reinforcing dead zones. This setup costs approximately $5,000 and consumes around 750 watts of energy. However, if the small cells initially used to cover dead zones are replaced with 2 RIS units, the cost is reduced to approximately $3,400, and power consumption is lowered to 604 watts.

The collaboration between YTTEK, DIREK, and the University of Surrey integrates cross-disciplinary technologies. It combines Y.RIS with AI-assisted tracking technology, sparking the most intelligent and energy-efficient 5G mmWave, B5G/6G solutions.

LEARN MORE ABOUT Y.RIS

Due to the scarcity of spectrum and the increasing demand for high throughput, the spectrum is anticipated to move towards higher frequencies in the future B5G/6G generation. However, higher frequencies have shorter wavelengths, which results in challenges such as lower coverage and increased susceptibility to obstacles like walls. Solutions to this include deploying more small cells, repeaters, and Reconfigurable Intelligent Surfaces (RIS) to extend the signal range of base stations.

What is Reconfigurable Intelligent Surface (RIS)?

RIS is typically a passive device with materials capable of manipulating electromagnetic wavefronts. By adjusting the properties of these surfaces, RIS can modify the propagation characteristics of wireless signals, such as reflecting high-frequency signals toward specified directions. This capability helps overcome signal blockages and enhance the overall performance of wireless communication systems.

Y.RIS: Control Signal-reflected Direction with Liquid Crystals

YTTEK’s Y.RIS is a liquid crystal-based RIS device operating in the 28GHz frequency band. It leverages well-established LCD panel manufacturing processes and integrates metasurface technology by designing metasurface antenna unit cells on a glass substrate. The phase control component applies voltage to the electrodes at both ends of the liquid crystal, inducing changes in the electric field. This alteration in the electric field modifies the polarization direction of the liquid crystal, thereby adjusting its effective dielectric constant (permittivity) and fine-tuning the signal phase, consequently altering the direction of signal reflection.

Exploring Y.RIS Applications

The compact and lightweight Y.RIS can be installed in various indoor spaces, such as homes and offices, to reflect signals to dead spots flexibly. Alternatively, it can be deployed in smart factories to expand the signal coverage for private broadband 5G/6G networks, ensuring stable signal connections for precision equipment and engineering facilities. Y.RIS is also suitable for installation in crowded venues like stadiums and airports to enhance the overall performance of high-frequency communication systems.

Cost and Energy Efficiency: Collaboration between Y.RIS and Small Cells (Y.BEAM G)

Collaboration between Y.RIS and small cells (Y.BEAM G) has the potential to generate a more cost-effective and energy-efficient communication system. For example, to set up a smart factory, 5 small cells are required, with 2 of them dedicated to reinforcing dead zones. This setup costs approximately $5,000 and consumes around 750 watts of energy. However, if the small cells initially used to cover dead zones are replaced with 2 RIS units, the cost is reduced to approximately $3,400, and power consumption is lowered to 604 watts. Through the integration of Y.RIS with small cells, a more efficient 5G mmWave communication system can be created.

Leveraging years of innovation in mmWave technology and the technical strength of liquid crystal panel manufacturer, YTTEK has created the revolutionary LC-RIS solution, laying the groundwork for a better B5G/6G Solution in advance.
