Summary

• What is new: Introduction of distributed BD-RIS as a solution for extending coverage in wireless networks beyond the limitations of conventional and localized RIS technologies.
• Why this is important: Conventional RIS and BD-RIS technologies are limited by their inability to effectively serve users beyond their immediate proximity, resulting in limited coverage.
• What the research proposes: Investigation into distributed BD-RIS, which distributes RIS elements over a wide region rather than concentrating them, to achieve broader coverage.
• Results: Distributed BD-RIS can achieve significant performance gains over both conventional RIS and localized BD-RIS, even when accounting for losses in signal transmission.

Technical Details

Technological frameworks used: Transmission line theory for modeling and optimizing BD-RIS with lossy interconnections.

Models used: Scaling laws for distributed BD-RIS, accounting for phase changes and losses.

Data used: nan

Potential Impact

Wireless network providers and companies invested in network infrastructure technologies may significantly benefit or need to adapt to incorporate distributed BD-RIS advancements.
