Dynamic Transmission Unit Sizing for Signal Strength Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data packet transmission between electronic devices often relies on static transmission unit sizes, which can lead to suboptimal performance due to varying signal strength, resulting in either high latency or reduced throughput.
Innovation Solution
Implementing dynamic transmission unit sizing based on received signal strength indicator (RSSI) values, where devices adjust the transmission unit size dynamically in response to changing RSSI thresholds to optimize data transmission, using smaller units for high RSSI values to reduce latency and larger units for low RSSI values to increase throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static transmission unit size is used, then device configuration compatibility is maintained, but data transmission performance deteriorates due to varying signal strength
Solution Approach 1:
The patent implements dynamic transmission unit sizing where the transmission unit size is adjusted in real-time based on RSSI values. The system transitions from a static configuration to a dynamic adaptation mechanism, allowing the transmission unit size to change according to signal strength conditions, thereby resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent changes the transmission unit size parameter based on RSSI threshold comparisons. When RSSI exceeds a threshold, a smaller transmission unit size is selected; when RSSI is below the threshold, a larger transmission unit size is used. This parameter adaptation resolves the contradiction by making the system adaptable to signal conditions while maintaining manageable complexity through predefined thresholds.
2Loss of time
If smaller transmission unit size is used, then latency is reduced, but throughput decreases when signal strength is weak
Solution Approach 1:
The patent dynamically adjusts the transmission unit size parameter based on RSSI values to optimize the trade-off between latency and throughput. When signal strength is strong (high RSSI), smaller transmission units are used to reduce latency. When signal strength is weak (low RSSI), larger transmission units are used to maintain throughput, thereby resolving the contradiction between these two performance metrics.
Solution Approach 2:
The system dynamically selects transmission unit size based on real-time RSSI conditions, allowing it to adapt between latency-optimized and throughput-optimized modes. This dynamic adjustment resolves the contradiction by matching the transmission unit size to the current signal conditions rather than using a fixed size that cannot satisfy both requirements simultaneously.
3Productivity
If larger transmission unit size is used, then throughput is increased, but latency increases when signal strength is strong
Solution Approach 1:
The patent adjusts the transmission unit size parameter inversely to signal strength: when RSSI is high (strong signal), smaller transmission units are used to minimize latency; when RSSI is low (weak signal), larger transmission units are used to maximize throughput. This parameter inversion strategy resolves the contradiction by optimizing for the appropriate metric based on current signal conditions.
4Productivity
If dynamic transmission unit sizing is implemented, then transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic transmission unit sizing mechanism that adjusts based on RSSI values, improving transmission efficiency by adapting to signal conditions. The complexity is managed through the use of predefined RSSI thresholds and a finite set of transmission unit size options, making the dynamic system practical and implementable.
Solution Approach 2:
The system changes the transmission unit size parameter based on RSSI threshold comparisons, improving efficiency through adaptation while controlling complexity through predefined thresholds and discrete size options. This approach balances the benefits of dynamic adaptation with the practical constraints of implementation complexity.

AI summary
Systems and methods for dynamic maximum transmission unit determination are disclosed. For example, one or more triggering events may be detected to initiate determining whether to adjust transmission unit sizing for data transmission between devices. Received signal strength indicator (RSSI) values may be exchanged between the devices and those RSSI values may be utilized to determine a strength of a communication signal between devices. When the RSSI values are low, the communication signal strength may be weak and the devices may adjust the transmission unit size to be larger. In other examples when the RSSI values are high, the communication signal strength may be strong and the devices may adjust the transmission unit size to be smaller.
