Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple waveforms and frequencies are added to tactical communication systems to prevent jamming, then communication resilience is improved, but system complexity and cost increase significantly
Solution Approach 1:
The system is divided into separate functional modules: waveform generation module, frequency synthesis module, and core communication module. This segmentation allows multiple waveforms and frequencies to be added by simply configuring the generation modules without modifying the core communication infrastructure, thereby improving resilience while controlling complexity.
Solution Approach 2:
The communication system is designed with universal interfaces and protocols that can accommodate multiple waveform types and frequency ranges through software configuration rather than hardware changes. This multi-functionality enables the system to support various tactical waveforms (e.g., LF, HF, VHF, UHF) and frequencies, enhancing jamming resistance without proportionally increasing system complexity.
2Reliability
If multiple waveforms and frequencies are added to tactical communication systems, then communication resilience is improved, but cost of retrofitting and replacing equipment increases
Solution Approach 1:
The system enables addition of multiple waveforms and frequencies by changing software parameters and configuration settings rather than modifying hardware components. This approach allows existing equipment to be retrofitted with new waveform capabilities through firmware updates and configuration changes, significantly reducing retrofitting costs while maintaining improved communication resilience.
3Reliability
If multiple waveforms and frequencies are added to tactical communication systems, then communication resilience is improved, but labor inputs for implementation increase
Solution Approach 1:
The system includes pre-configured waveform templates and frequency profiles that can be deployed through automated configuration tools. These preliminary preparations allow multiple waveforms and frequencies to be implemented with minimal manual intervention, reducing the labor inputs required while achieving improved communication resilience through diverse waveform and frequency support.

AI summary
A communication system is disclosed. The communication system includes a first core network that is mobile, and a radio access network, which includes a first central unit and one or more distributed units. The first central unit includes a first router containing a multi-level security guard configured to route user plane data and control plane data to the first core network. The first central unit further includes a transceiver, a control plane interface coupled to the core network, and a second router configured to communicate user plane data and control plane data to one or more first distributed units. The central unit configures at least one network function of radio resource control (RRC). The one or more distributed units configures at least one network function of packet data convergence protocol (PDCP), radio link control (RLC), medium access control (MAC), and physical link (PHY) network functions.
