Wireless Transmission Power Adjustment for Distance Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless transmission systems face challenges in optimizing data rate and transmission distance when multiple transmitting ends transmit data to receiving ends at different distances, leading to uneven data reception and potential security loopholes, as they cannot accurately adjust transmission power to account for varying distances and power distribution among multiple receiving ends.
Innovation Solution
A wireless transmission system comprising a main wireless apparatus with a data rate analyzer and a master controller, which detects data rates between the main and secondary wireless apparatuses and adjusts transmission power to optimize data rate and transmission distance, ensuring all receiving ends receive data at a standard rate while conserving power by decreasing power to higher-rate transmitters and increasing power to lower-rate transmitters.

Engineering Contradiction Analysis
1Ease of operation
If the transmitting end transmits data by the same power to all receiving ends, then the transmission power distribution is simple and uniform, but the data rate and signal reception quality become uneven when receiving ends are at different distances
Solution Approach 1:
The patent applies local quality by assigning different transmission powers to different wireless modules based on their specific transmission distances and data rate requirements. Each wireless module's power is individually adjusted according to its local conditions (distance and data rate), rather than using a uniform power distribution, thereby optimizing signal reception quality for each receiving end.
Solution Approach 2:
The patent implements dynamics by making the transmission power adjustable and adaptive. The master controller dynamically adjusts the transmission power of each wireless module based on real-time distance measurements and data rate detections, allowing the system to adapt to changing transmission conditions and maintain reliable data reception.
2Length of stationary object
If the transmitting end increases transmission power to extend transmission distance, then the signal reception quality improves, but the power consumption increases
Solution Approach 1:
The patent applies parameter changes by adjusting the transmission power parameter based on the actual transmission distance and data rate requirements. Instead of using a fixed high power setting, the system dynamically modifies the power parameter to match the needed transmission distance, thereby extending range when necessary while minimizing power consumption when possible.
Solution Approach 2:
The patent implements feedback by continuously monitoring the data rate and transmission conditions, then using this information to adjust the transmission power. The master controller receives feedback about signal quality and distance, and accordingly modifies the power output to achieve optimal transmission distance with minimal power consumption.
3Device complexity
If the manufacturers assume equal transmission power for all wireless modules, then the device complexity is reduced, but the system cannot adapt to different transmission distances and data rate requirements
Solution Approach 1:
The patent applies preliminary action by pre-equipping each wireless module with the capability for independent power control and by implementing a master controller that can manage multiple modules. This preliminary setup allows the system to adapt to different transmission distances and data rate requirements without adding complex hardware, as the control infrastructure is already in place.
Solution Approach 2:
The patent implements universality by designing a master controller that can manage multiple wireless modules with different transmission characteristics. The system provides a universal control mechanism that adapts to various transmission scenarios (different distances, different data rate requirements) through a single integrated control architecture, avoiding the need for separate control systems for each module.

AI summary
A wireless transmission system capable of automatically adjusting transmission power includes a main wireless apparatus and plural secondary wireless apparatuses, and the main wireless apparatus is capable of detecting the data rate between the secondary wireless apparatuses, and increasing or decreasing the transmission power of any one of the secondary wireless apparatuses by a master controller, or increasing or decreasing the transmission power of the main wireless apparatus, so that the data rate and/or transmitting distance between the main wireless apparatus and the secondary wireless apparatuses can be optimized.
