Wireless Transmission Mode Switching for Range and Power Tradeoffs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, there is a trade-off between data rate and range, where increasing power to maintain signal strength in hostile environments increases detection likelihood, and power limitations from sources like batteries restrict throughput, necessitating a balance between power and data rate.
Innovation Solution
A method that dynamically adjusts transmission modes based on data transfer counts and signal quality, using a process where transceivers determine and communicate suggested and pending modes to optimize data transmission, balancing energy efficiency and detection risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the power of the transmission is increased to maintain signal strength at longer distances, then the range is improved, but the likelihood of being detected by an enemy increases and power consumption increases
Solution Approach 1:
The patent implements dynamic mode switching between different transmission modes (first mode with higher data rate and second mode with lower data rate but better range) based on real-time channel conditions and security requirements. The system transitions from static power level selection to dynamic adaptation, allowing the transmitter to adjust between modes with different power consumption characteristics to optimize both range and security.
Solution Approach 2:
The system changes transmission parameters (data rate, power level, mode) based on channel quality indicators and security context. By varying these parameters dynamically rather than using fixed settings, the system can achieve extended range when needed while minimizing detection risk during normal operations, directly addressing the contradiction between range and security.
2Length of stationary object
If the power of the transmission is increased to maintain signal strength at longer distances, then the range is improved, but the power consumption increases
Solution Approach 1:
The patent employs dynamic power management by switching between transmission modes based on actual channel conditions. Instead of maintaining high power consumption continuously to ensure range, the system adapts power levels dynamically - using higher power only when channel conditions warrant it and lower power during favorable conditions, thus extending range while conserving battery energy.
Solution Approach 2:
The system performs self-adjustment of power consumption by monitoring channel quality indicators and autonomously selecting appropriate transmission modes. This self-service mechanism eliminates the need for external power management intervention, allowing the system to optimize its own power usage to maintain range while minimizing energy consumption from battery or vehicle power sources.
3Use of energy by moving object
If the data rate is decreased to conserve power, then the power consumption is reduced, but the throughput decreases
Solution Approach 1:
The patent implements dynamic data rate adjustment by switching between first mode (higher data rate) and second mode (lower data rate) based on channel conditions and security requirements. This dynamic approach allows the system to achieve high throughput when channel quality permits while consuming less power during poorer conditions, resolving the contradiction between power consumption and productivity.
Solution Approach 2:
The system changes the data rate parameter dynamically based on channel quality indicators and security context rather than using a fixed data rate. This allows optimization of the throughput-power tradeoff by adjusting the data rate to match current conditions, achieving high productivity when possible while conserving power when necessary.

AI summary
In one aspect, the invention is a method that includes transferring data at an initial mode from a transmitter to a receiver, determining a suggested mode based on the data transferred and determining a count of the data transferred from the transmitter to the receiver. The method also includes transferring the suggested mode and the count to the transmitter and determining a pending mode based on the suggested mode and the count.
