System And Method Of High-Speed Wireless Communications Using Reflected Laser Light

Smart overview of the Invention

A novel system and method for high-speed wireless communications using reflected laser light has been developed, particularly useful in disaster-struck areas or locations with limited communication capabilities. This system employs a Non-direct Line-of-Sight Free-Space Optical Communications (NLoS-FSOC) network, which utilizes diffuse reflectors to establish a broadcast optical channel between transmitters and receivers. Both drone-assisted and non-drone assisted configurations are available, allowing for flexible deployment in various scenarios.

Advantages Over Traditional Methods

Compared to traditional radio frequency (RF) communications, this new system offers significant advantages. It can service at least 130% more stations and achieve over 100% higher aggregated downlink data rates while consuming 116 times less energy. The use of high-bandwidth optical signals and coherent laser light enables more efficient communication, making it a compelling alternative to existing RF-based schemes.

Application in Disaster Response

The system is particularly beneficial during emergencies, as it allows for rapid collection and dissemination of information about disaster sites. Drones can be deployed to extend communication ranges, providing critical support to rescue teams. The framework also includes algorithms for optimizing drone placement and access time to maximize coverage and efficiency in service delivery.

Implementation Details

This communication framework includes the use of diffuse reflectors (DRs) that can be mounted on drones or fixed installations. These DRs facilitate the creation of an optical local area network (OLAN), enabling stations within line-of-sight to communicate effectively. The drones act as relays, connecting ground stations with remote optical base stations (OBS), thus enhancing overall communication capabilities in challenging environments.

Future Prospects

The potential for further development exists in expanding the number of DRs, receivers, and transmitters used in each drone, enhancing the network’s capacity and performance. By utilizing passive materials for DRs, the system minimizes energy consumption while maximizing data transfer rates. This innovative approach represents a significant advancement in emergency communication technologies, promising improved response times and resource efficiency during critical operations.
