Single-Core Wi-Fi Module Channel Sharing for Hotspot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices using dual-core Wi-Fi modules for mobile hotspot and Wi-Fi communication incur increased production costs and power consumption, as well as higher user data fees due to the need for multiple frequency bands and channels.
Innovation Solution
An electronic device equipped with a single-core Wi-Fi module that establishes both Wi-Fi and mobile hotspot links on the same channel, using a processor to detect changes in the Wi-Fi link state and adjust the mobile hotspot link accordingly, thereby reducing costs and fees by conforming to regulations such as indoor-only or DFS channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual-core Wi-Fi module is used to perform both Wi-Fi communication and mobile hotspot communication simultaneously, then both functions can be provided, but production cost increases
Solution Approach 1:
The patent merges Wi-Fi communication and mobile hotspot communication functions into a single-core Wi-Fi module by implementing a channel sharing mechanism where both functions share the same radio frequency resources and processing core, eliminating the need for separate dual-core hardware
Solution Approach 2:
The single-core Wi-Fi module is designed to perform multiple functions (both Wi-Fi client communication and mobile hotspot routing) through software-based channel management and time-division multiplexing, making the hardware universal rather than specialized
2Adaptability or versatility
If a dual-core Wi-Fi module is used to perform both Wi-Fi communication and mobile hotspot communication simultaneously, then both functions can be provided, but current consumption increases
Solution Approach 1:
The patent combines both communication functions into a single processing core that dynamically allocates processing power and radio resources, avoiding the continuous power consumption of two simultaneously active cores
Solution Approach 2:
The system uses periodic time-division multiplexing where the single core alternates between handling Wi-Fi communication tasks and mobile hotspot routing tasks, allowing the radio to be efficiently shared between functions rather than continuously powered at full capacity
3Adaptability or versatility
If a dual-core Wi-Fi module is used to perform both Wi-Fi communication and mobile hotspot communication simultaneously, then both functions can be provided, but user data fees increase
Solution Approach 1:
The single-core module provides universal Wi-Fi functionality that can operate in both client mode and hotspot mode, allowing users to choose the more economical option (connecting to existing Wi-Fi rather than creating a hotspot that consumes cellular data)

AI summary
An electronic device includes a housing, at least one antenna located in the housing, a Wi-Fi module that is electrically connected with the at least one antenna, supports a Wi-Fi protocol, and includes one core, a processor that is located in the housing and is operatively connected with the Wi-Fi module, and a memory operatively connected with the processor. The memory stores instructions, when executed, causing the processor to establish a Wi-Fi link on a first channel with an access point (AP), through the Wi-Fi module, establish a mobile hotspot link on the first channel with an external electronic device, through the Wi-Fi module, detect an event associated with a change in state of the Wi-Fi link, and change a state of the mobile hotspot link, based at least on the detected event.
