Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple wireless access points or relay nodes are introduced to extend communication range, then wireless coverage is improved, but latency increases
Solution Approach 1:
The system segments the wireless communication into two independent parallel channels: a first wireless channel for control signaling and a second wireless channel for data transmission. This segmentation allows the control plane and data plane to operate simultaneously without interfering with each other, reducing the latency penalty associated with multiple relay nodes while maintaining extended coverage area.
Solution Approach 2:
The patent introduces a spatial dimension by using different frequency bands (first and second frequency bands) for control and data transmission respectively. This dimensional separation allows simultaneous operation of multiple access points without the latency accumulation that would occur in traditional single-channel mesh networks.
2Reliability
If traditional digital backhaul solutions are deployed, then network infrastructure is established, but complexity and cost increase
Solution Approach 1:
The system extracts the control signaling function from the data transmission function and places it in a separate first wireless channel. This extraction simplifies the backhaul network architecture by allowing data to be transmitted directly over the second wireless channel without complex digital processing and routing decisions, reducing both complexity and cost while maintaining reliable connectivity.
Solution Approach 2:
The patent replaces complex digital backhaul processing with a simpler analog-like direct transmission approach over the second wireless channel. By using frequency division to separate control and data paths, the system eliminates the need for complex digital routing and processing at each relay node, reducing implementation complexity.
3Area of stationary object
If RF signals are transmitted in dense urban environments, then coverage is provided, but signal interference and blockages increase
Solution Approach 1:
The system segments the electromagnetic spectrum into two separate frequency bands for control and data transmission. This frequency segmentation reduces interference between different wireless systems operating in dense urban environments, as each band can be optimized for its specific function and less susceptible to blockages and interference from other devices.
