UAS Route and Frequency Control Under Interference Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dynamic spectrum access (DSA) technologies are inadequate for optimizing frequency use efficiency and operation routes of mobile communication devices like unmanned aircraft systems (UAS), as they primarily focus on fixed transmitter environments and do not account for mobile terminals.
Innovation Solution
A communication control device and method that integrates a frequency management system and an operation plan/interference power management system to dynamically allocate frequencies and construct operation routes for UAS, ensuring minimal interference and efficient frequency use by managing radio parameters and operation plans.

Engineering Contradiction Analysis
1Productivity
If multiple movable communication devices operate simultaneously in the same frequency band, then frequency utilization efficiency improves, but interference power received by each device increases
Solution Approach 1:
The system dynamically determines movement routes and transmission parameters for multiple communication devices based on real-time positional information and request information. The control unit adjusts each device's route and transmission power dynamically to maintain cumulative interference power within allowable limits while maximizing frequency utilization efficiency.
Solution Approach 2:
The control unit changes key parameters including movement routes, transmission power, and operation timing for each communication device. By adjusting these parameters, the system ensures that cumulative interference power received by each device does not exceed allowable values while enabling simultaneous operation of multiple devices in the same frequency band.
2Object-affected harmful factors
If movement routes are optimized to reduce interference, then interference power decreases, but route planning complexity increases
Solution Approach 1:
A central control unit acts as an intermediary to manage route planning for multiple communication devices. The control unit receives positional information and request information from various devices, processes this information centrally, and determines optimal movement routes that minimize interference while keeping individual device complexity low.
Solution Approach 2:
The control unit determines movement routes in advance based on request information before the communication devices begin operation. This preliminary route planning ensures that interference power is controlled from the outset, and devices can follow predetermined routes without requiring complex real-time decision-making.

AI summary
Use efficiency of frequencies used by a plurality of movable communication devices is improved. A communication control device of the present disclosure is a communication control device that controls a plurality of movable communication devices, and includes a control unit that acquires each piece of request information regarding movement of the communication devices, and determines a movement route of each of the communication devices on the basis of the request information so that a cumulative interference power received by each of the communication devices from another of the communication devices becomes equal to or less than an allowable value.
