研究目的
To design, develop, and deploy the world’s first optical wireless communication (OWC) system using off-the-shelf lasers and solar photovoltaics for high-speed internet access in remote areas.
研究成果
The developed OWC system demonstrates the feasibility of using solar panels for simultaneous energy harvesting and high-speed data communication in remote areas. The system achieved data rates up to 8 Mb/s and harvested up to 5 W of power, outperforming existing landline broadband connections in some scenarios. This approach offers a low-cost, self-powered solution for rural and remote communities.
研究不足
The system's performance is affected by weather conditions, with data rates dropping during sunny periods and rain. The study focuses on first-generation solar panels, which may not represent the latest advancements in solar technology.
1：Experimental Design and Method Selection:
The study involved designing and deploying bidirectional OWC prototypes using off-the-shelf lasers and solar panels. The methodology included theoretical models for solar panel performance and detailed procedures for system integration and testing.
2：Sample Selection and Data Sources:
The prototypes were installed on the Orkney Islands of Scotland, targeting two residential properties for real-world testing.
3：List of Experimental Equipment and Materials:
Equipment included off-the-shelf lasers, silicon-made solar panels, and additional analogue processing units. Specifications and intended uses were detailed for each component.
4：Experimental Procedures and Operational Workflow:
The process involved setting up the OWC system, optimizing the laser beam and solar panel alignment, and conducting performance tests under various weather conditions.
5：Data Analysis Methods:
Performance metrics such as data rate and power harvesting efficiency were analyzed using statistical techniques and software tools.
