Bandwidth Adaptation for Mobile Hotspot Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices that provide a mobile hotspot function, the bandwidth of the link between the device and an external electronic device may be smaller than the bandwidth of the link between the device and another external device, leading to increased standby power consumption as the external device waits to transmit or receive data.
Innovation Solution
The electronic device identifies the bandwidths of both links and, if the second link has a larger bandwidth, it analyzes the traffic data of the second external device. If the traffic meets certain conditions, such as data size or latency requirements, the device reduces the bandwidth of the second link to minimize power consumption.

Engineering Contradiction Analysis
1Speed
If the bandwidth of the second link is increased to improve data transmission speed, then the data transmission speed between the electronic device and the second external electronic device is improved, but the standby power consumption of the second external electronic device increases
Solution Approach 1:
The patent applies dynamics by making the bandwidth configuration adaptive rather than static. The system dynamically adjusts the bandwidth of the second link based on real-time network conditions, data traffic patterns, and power consumption thresholds. When power consumption exceeds the threshold or network conditions change, the bandwidth is reconfigured to an optimal level, ensuring both high data transmission speed and low power consumption at different operational states
Solution Approach 2:
The patent changes the bandwidth parameter of the second link based on identified data traffic patterns and power consumption levels. By analyzing the relationship between bandwidth settings and power consumption, the system selects appropriate bandwidth parameters that satisfy both performance requirements and power constraints, thereby resolving the contradiction between transmission speed and power usage
2Use of energy by moving object
If the bandwidth of the second link is reduced to decrease power consumption, then the standby power consumption is reduced, but the data transmission speed decreases
Solution Approach 1:
The system dynamically adjusts bandwidth based on actual network conditions and traffic requirements. During periods of low activity, bandwidth is reduced to minimize power consumption. When data transmission demands increase, the system detects these changes and adjusts bandwidth upward to maintain required transmission speeds, thus dynamically balancing power efficiency and performance
Solution Approach 2:
The system performs preliminary analysis of data traffic patterns and power consumption characteristics to predict optimal bandwidth settings. By pre-identifying traffic patterns and their associated power consumption levels, the system can proactively adjust bandwidth before power consumption becomes excessive or transmission speed becomes insufficient, maintaining optimal operation
