Solution Overview
Problem
Existing wireless devices in ad-hoc networks lack the ability to dynamically adjust transmit signal power levels based on changing ranges between devices, leading to inefficient power usage, reduced battery life, and increased risk of eavesdropping.
Innovation Solution
A method and device that detect usage parameters such as signal strength or range to adjust transmit signal power levels, allowing for seamless transitions between different power classes (Class 1, 2, and 3) to optimize communication range and security, featuring a parameter detection circuit and power selection circuit to set appropriate power levels for communication with multiple nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the transmit power level is set to maximum, then the communication range is extended, but the power consumption increases and battery life is reduced
Solution Approach 1:
The patent implements dynamic power level adjustment by detecting the current communication range and automatically switching between predefined power classes (Class 1, 2, and 3) to match the actual transmission needs. This dynamic adaptation allows the system to extend range when necessary while conserving power during normal operation, resolving the contradiction between communication range and power consumption.
Solution Approach 2:
The system changes the transmit power parameter by switching between different power classes based on detected usage conditions. When the detected range exceeds a threshold, the system transitions to a higher power class; when within acceptable range, it maintains or switches to a lower power class, thereby optimizing the power parameter according to actual communication requirements.
2Length of stationary object
If the transmit power level is set to maximum, then the communication range is extended, but the risk of eavesdropping increases
Solution Approach 1:
The system dynamically adjusts power levels based on detected range requirements, using higher power only when the communication distance exceeds current capabilities. This minimizes the time and conditions under which high-power transmissions occur, thereby reducing the window of opportunity for eavesdroppers while still ensuring adequate range when needed.
Solution Approach 2:
By switching between power classes based on detected usage parameters, the system changes the transmit power parameter to match actual needs rather than maintaining a constant high level, thereby extending range only when necessary and reducing overall exposure to potential eavesdropping threats.
3Device complexity
If a fixed power level is used, then the device complexity is reduced, but the adaptability to different communication scenarios is limited
Solution Approach 1:
The patent implements a dynamic power control system that automatically detects communication range and switches between predefined power classes. This dynamic approach provides adaptability to different scenarios while maintaining relatively simple implementation through predefined power levels and threshold-based switching logic, resolving the contradiction between complexity and adaptability.
Solution Approach 2:
The system changes the power parameter based on detected usage conditions, switching between predefined power classes to adapt to different communication scenarios. This parameter adaptation enhances versatility while keeping the control mechanism relatively simple through threshold-based decision logic.
4Use of energy by moving object
If the transmit power is reduced to save battery, then the power consumption is reduced, but the communication range becomes insufficient
Solution Approach 1:
The system dynamically adjusts power levels by detecting the actual communication range and switching between power classes accordingly. When the detected range is within acceptable limits, the system uses lower power classes to conserve battery. When the range becomes insufficient, it automatically switches to higher power classes to extend communication distance, thus dynamically balancing power consumption and range requirements.
Solution Approach 2:
The system changes the power parameter based on detected usage parameters, switching between power classes to match actual communication needs. This ensures adequate range is maintained while minimizing power consumption by using the lowest necessary power level for each scenario.

AI summary
In a method of controlling power level of transmit signals from a wireless communication device that is communicating with a plurality of wireless ad-hoc network nodes as part of an ad-hoc network, a value of a usage parameter of a communication between the wireless device and a first wireless ad-hoc network node of the plurality of nodes is detected. A power level of a transmit signal from the wireless device to the first wireless ad-hoc network node is set to a level corresponding to the value of the usage parameter. A device for adjusting a power level in a wireless device includes a parameter detection circuit, that detects a parameter indicative of a relationship between the wireless device and a wireless ad-hoc network node, and a power selection circuit that sets a transmit signal power level from the wireless device to a level corresponding to the parameter detected by the parameter detection circuit.
