UAV Remote-ID Beaconing Across Narrowband and Wideband Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone communication technologies face challenges in complying with Remote-ID standards while maintaining efficient narrowband flight control operations, as transitioning to wideband channels for beacon transmission incurs significant delays and disrupts communication with control nodes.
Innovation Solution
Unmanned aerial vehicles (UAVs) utilize the same RF/radio circuitry to periodically switch between narrowband flight control channels and wider bandwidths for beacon transmission, allowing compliance with Remote-ID standards without disrupting flight control operations by briefly transitioning to a social channel for beacon frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drone uses a wideband channel for beacon transmission to comply with Remote-ID standards, then the Remote-ID information can be transmitted effectively, but the flight control communication experiences significant delays and disruptions
Solution Approach 1:
The patent segments the communication functions by separating Remote-ID beacon transmission from flight control communication. The drone uses different channels for different purposes: a wideband channel (channel 149) for Remote-ID beacons and narrowband channels for flight control. This segmentation allows each function to operate optimally on its designated channel without interfering with the other, resolving the contradiction between reliable Remote-ID transmission and continuous flight control communication.
Solution Approach 2:
The patent implements periodic beacon transmission at 100Hz (every 10ms) on the wideband channel while maintaining continuous narrowband flight control communication. This periodic action allows the drone to comply with Remote-ID standards requiring at least one beacon per second, while the brief 10ms intervals between beacons are sufficient to maintain uninterrupted flight control links, thus resolving the time loss issue.
2Reliability
If the drone switches channels frequently for beacon transmission, then Remote-ID compliance is achieved, but communication stability with control nodes deteriorates
Solution Approach 1:
The patent segments communication into two distinct channels: a wideband channel (channel 149) dedicated to Remote-ID beacons and narrowband channels dedicated to flight control. By segmenting the functions spatially (different frequencies), the system achieves Remote-ID compliance through periodic wideband beacon transmission while maintaining stable narrowband flight control links, eliminating the stability issues caused by frequent channel switching.
Solution Approach 2:
The patent ensures continuous flight control communication by maintaining the narrowband link active throughout beacon transmission cycles. The 100Hz beacon rate with 10ms intervals allows the narrowband flight control channel to remain continuously established, ensuring uninterrupted control commands and telemetry while still achieving Remote-ID compliance through periodic wideband beacon insertion.
3Productivity
If the drone uses narrowband channels for flight control to maintain efficiency, then control communication is optimized, but Remote-ID beacon transmission with required bandwidth is compromised
Solution Approach 1:
The patent segments the spectrum into narrowband channels for efficient flight control communication and a wideband channel (channel 149) for Remote-ID beacon transmission. This segmentation allows the drone to maintain optimized narrowband links for high-efficiency flight control while using the wideband channel's greater bandwidth to transmit complete Remote-ID information including location, altitude, direction, and other required data elements.
Solution Approach 2:
The patent makes the wireless communication system multi-functional by enabling it to operate on both narrowband and wideband channels. The same communication hardware performs dual functions: narrowband flight control communication for efficient command and telemetry, and wideband Remote-ID beacon transmission for regulatory compliance. This universality allows the system to leverage the advantages of both bandwidth regimes for their respective purposes.
