Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles require seamless and robust connectivity for continuous real-time data transmission, including command and control data and payload communication, while ensuring high security standards due to their dynamic nature and potential risks.
Innovation Solution
The implementation of a communication interface with both an optimized cellular narrowband mobile network and a cellular broadband mobile network allows for the efficient transmission and reception of command and control data and payload communication data, enabling the separation of communication channels and flexible allocation of communication capacities based on specific needs, such as emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication channel is used for all data transmission, then device complexity is reduced, but reliability and security are compromised due to inability to prioritize critical command and control data
Solution Approach 1:
The communication interface is segmented into two independent air interfaces: a first air interface for narrowband command and control data transmission, and a second air interface for broadband payload data transmission. This segmentation allows critical control commands to be transmitted through a dedicated reliable channel while bulk data uses a separate channel, ensuring that control functionality remains reliable even when payload transmission experiences issues.
2Speed
If broadband network is used for all communications, then data transmission speed is improved, but energy consumption increases and reliability for critical control data decreases
Solution Approach 1:
Different communication quality levels are applied to different data types: narrowband low-power communication is used for critical command and control data requiring high reliability, while broadband high-speed communication is used for payload data requiring high throughput. This local quality differentiation optimizes energy consumption by using the most efficient communication mode for each specific data type rather than uniformly using broadband for all transmissions.
3Adaptability or versatility
If multiple air interfaces are implemented, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The communication interface is designed with multi-functionality to handle both narrowband and broadband communications through two air interfaces. This universal design allows the unmanned aerial vehicle to adapt to different network conditions and data requirements, maintaining versatility while managing complexity through a standardized dual-interface architecture that can be systematically implemented across different vehicle types.

AI summary
A method for optimized data transmission between an unmanned aerial vehicle and a telecommunications network includes: transmitting, by the unmanned aerial vehicle, command and control data and/or payload communication data in an uplink direction from the unmanned aerial vehicle to the telecommunications network; and/or receiving, by the unmanned aerial vehicle, command and control data and/or payload communication data in a downlink direction from the telecommunications network to the unmanned aerial vehicle. The unmanned aerial vehicle comprises a communication interface to transmit the command and control data and/or the payload communication data in the uplink direction and/or to receive the command and control data and/or the payload communication data in the downlink direction, wherein the communication interface comprises a first air interface towards an optimized cellular narrowband mobile network and a second air interface towards a cellular broadband mobile network.
