What does "Smart Radio Environment" mean?
Table of Contents
A Smart Radio Environment (SRE) is an advanced system used in modern mobile networks, especially as we move towards 6G technology. It involves using different tools and technologies to improve how we connect and communicate over wireless networks.
Key Components
SRE includes several important elements:
- Reconfigurable Intelligent Surface (RIS): This tool can change its shape and function to improve signal quality and coverage.
- Network-Controlled Repeater (NCR): This helps boost signals across the network.
- Simultaneous Transmitting and Reflecting RIS (STAR RIS): This is a more advanced version of RIS, allowing for two-way communication.
- Trisectoral NCR (3SNCR): This design helps manage the signal in multiple directions at once.
Network Planning
When planning a network using SRE, experts consider various factors like costs and how well signals travel in different urban settings. They focus on achieving full coverage at the lowest cost or maximizing coverage within a set budget.
Benefits
Using a Smart Radio Environment can greatly enhance network performance in busy urban areas. It helps deal with the increasing demand for mobile data, ensuring that people can connect without delays or interruptions.
