Integrated Wireless System with Dual Module Switching for Signal Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with embedded wireless communication modules face reduced coverage and throughput due to the shielding of wireless signals caused by the placement of component housings, which are often placed inside closed cabinets or at the rear end of display panels to conserve space.
Innovation Solution
An integrated wireless system with multiple wireless communication modules, where one module is housed outside the component housing and another within, along with a switching engine that selects the module with higher Modulation and Coding Scheme (MCS) index for optimal data rate, allowing for improved coverage and throughput by switching between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wireless communication module is placed inside the component housing to conserve space, then the device size is reduced, but the wireless signal coverage and throughput are reduced due to shielding
Solution Approach 1:
The wireless communication system is divided into two separate modules: a first wireless communication module placed outside the component housing and a second wireless communication module placed inside the component housing. This segmentation allows each module to operate in different spatial environments, with the external module providing superior signal coverage and the internal module enabling compact device integration.
Solution Approach 2:
A switching engine is introduced as an intermediary component that dynamically selects between the first and second wireless communication modules based on MCS index comparisons. The switching engine monitors the performance of both modules and routes wireless communications through the optimal module, thereby resolving the contradiction between device compactness and signal performance.
2Device complexity
If a single wireless communication module is used, then the device complexity is reduced, but the adaptability to different communication conditions is limited
Solution Approach 1:
The wireless communication system implements dynamic adaptability through the switching engine, which continuously monitors MCS indices from both wireless communication modules and dynamically selects the optimal module based on current communication conditions. This dynamic switching capability allows the system to adapt to varying signal environments, device positions, and communication requirements without requiring manual configuration.
Solution Approach 2:
The system changes the operational parameter (active wireless module) based on MCS index values, which reflect the quality of wireless communication conditions. By monitoring and comparing MCS indices from different modules, the system selects the module with the higher MCS index, thereby optimizing communication performance under different conditions such as device orientation, distance from access points, and environmental interference.

AI summary
Techniques for establishing a wireless connection in a computing device are described. In an example, the computing device includes an integrated wireless system having multiple wireless communication modules, where the multiple wireless modules include a first wireless communication module housed outside a component housing of the computing device and a second wireless communication module housed within the component housing. In operation, switching may be performed between the first wireless communication module and the second wireless communication module based on their respective modulation and coding scheme (MCS) indexes to select a wireless communication module for establishment of the wireless connection.
