Interface Mode Selection for Wireless Data Bottleneck Reduction

Solution Overview

Problem

The difference between the maximum data rate of a channel generated between an electronic device and an external device and the maximum data rate supported by the interface operation mode can result in deteriorated data transmission rates and increased power consumption.

Innovation Solution

An electronic device selects an operation mode for its interface based on capability information received from the external device before establishing short-range wireless communication, ensuring the selected mode supports a data rate higher than the channel's maximum data rate.

1Productivity

If the interface operates in a high data rate mode to match the channel capability, then the data transmission rate is improved, but the power consumption increases

Engineering Contradiction:

Improvedata transmission rateVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The interface operation mode is made dynamic by allowing switching between multiple modes (first operation mode with higher data rate, second operation mode with lower data rate) based on real-time channel conditions and external device capabilities. The processor selectively activates the appropriate mode to match actual transmission needs, avoiding sustained high-power operation when full capacity is not required.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the interface by adjusting the data rate mode based on capability information from the external device and channel conditions. The processor receives capability information indicating maximum data rate support and accordingly selects an operation mode that matches or exceeds this capability, optimizing both throughput and energy efficiency.

Solution Approach 2:

The system uses feedback from the external device's capability information to adjust the interface operation mode. The processor receives feedback about the external device's maximum data rate capability and uses this information to select an appropriate mode, ensuring the interface operates at an optimal point that avoids bottlenecking the wireless channel while maintaining reasonable power consumption.
