1Productivity
If directional sensing with fixed antenna beamwidth and sensing sensitivity is used, then the device structure is simple, but spectral efficiency is reduced due to interference and inability to adapt to different distances
Solution Approach 1:
The patent applies dynamics by making the antenna beamwidth and sensing sensitivity adjustable rather than fixed. The system dynamically selects from multiple predefined beamwidth-sensitivity combinations based on determined distance to target devices, allowing adaptation to varying spectral conditions and distances, thereby improving spectral efficiency without requiring completely new complex systems
Solution Approach 2:
The patent changes physical parameters (antenna beamwidth and sensing sensitivity) to resolve the contradiction. By predefining multiple combinations of these parameters and selecting appropriate combinations based on distance, the system achieves adaptive spectral efficiency improvement while controlling complexity through predefined options rather than continuous adjustment mechanisms
2Measurement precision
If high sensing sensitivity is used to detect low energy levels, then spectral interference detection is improved, but false detections increase and energy consumption rises
Solution Approach 1:
The patent changes the sensing sensitivity parameter dynamically based on determined distance. By selecting from predefined sensitivity levels matched to distance ranges, the system achieves accurate detection when needed (high sensitivity for distant devices) while reducing energy consumption when high sensitivity is not necessary (lower sensitivity for nearby devices), thus resolving the contradiction between detection accuracy and energy loss
3Measurement precision
If narrow antenna beamwidth is used to reduce interference, then directional precision is improved, but coverage area is reduced and transmission reliability decreases
Solution Approach 1:
The patent applies dynamics by making antenna beamwidth adjustable based on distance to target devices. The system dynamically selects from multiple predefined beamwidth options, using narrower beams for distant devices requiring precision and wider beams for nearby devices requiring coverage, thereby maintaining transmission reliability across varying conditions while preserving directional precision when needed
Solution Approach 2:
The patent changes the antenna beamwidth parameter in conjunction with sensing sensitivity based on determined distance. By predefining coordinated combinations of beamwidth and sensitivity values, the system optimizes the trade-off between directional precision and transmission reliability for different distance scenarios, achieving both improved precision and maintained reliability
