Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single frequency band is used for wireless transmission, then the device complexity is reduced, but the communication reliability deteriorates due to signal interference
Solution Approach 1:
The communication module is segmented into multiple independent frequency band processing units. Each unit handles a specific frequency band separately, allowing the system to transmit and receive signals on multiple frequency bands simultaneously while maintaining manageable complexity through modular design
Solution Approach 2:
The system transitions from single-frequency-band operation to multi-frequency-band operation, adding the frequency band dimension to the communication system. This allows signals to be transmitted and received across multiple frequency dimensions simultaneously, improving reliability through frequency diversity
2Productivity
If multiple receiving units of a single frequency band are used, then the receiving capability is improved, but the communication reliability still deteriorates due to inability to avoid single frequency band interference
Solution Approach 1:
The system changes the frequency band parameter from single-band to multi-band operation. By operating on multiple frequency bands simultaneously, the system achieves both improved receiving capability and enhanced reliability through frequency diversity, avoiding the limitation of single-frequency-band interference

AI summary
A wireless communication system and a drone system using the wireless communication system are provided. The wireless communication system includes a first communication module and a second communication module. The first communication module transmits a same signal in a first frequency band and a second frequency band respectively by means of power splitting and frequency conversion, the first frequency band being different from the second frequency band. The second communication module separately receives the signal transmitted by the first communication module in the first frequency band and the signal transmitted by the first communication module in the second frequency band, and converts the received signal of the second frequency band into the signal of the first frequency band through frequency conversion, and performs diversity reception with the received signal of the first frequency band. The present utility model can effectively avoid interference of a single frequency band, to improve the reliability of communication.
