Master Device Wifi Sharing via Ethernet Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wifi devices often experience interference due to the need for each electronic device to have an independent physical Wifi device, which is not replaceable by Ethernet, hindering efficient data transmission.
Innovation Solution
Implementing a method where a master device with a wireless network interface card shares its Wifi component with module devices via an Ethernet bridge, using a virtual wireless network interface card and Ethernet interface card to transmit data, thereby avoiding interference and enabling data sharing without physical Wifi devices on module devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each electronic device is provided with an independent physical Wifi device, then each device can independently access the network, but interference exists between Wifi devices
Solution Approach 1:
The patent merges multiple module devices' network access needs into a single master device's physical Wifi component. The master device shares its physical Wifi hardware with multiple module devices through Ethernet connections, eliminating the need for each module device to have its own physical Wifi device while reducing interference.
Solution Approach 2:
The patent introduces an Ethernet bridge as an intermediary between the master device and module devices. This bridge manages data transmission between the shared physical Wifi component and multiple module devices, enabling efficient data routing without direct Wifi-to-Wifi interference.
2Adaptability or versatility
If a physical Wifi device is used on each module device, then independent Wifi functionality is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple Wifi functionalities into a single physical Wifi device located in the master device. This consolidation reduces the total number of Wifi devices from N (one per module device) to 1 (shared by all), thereby reducing device complexity while maintaining network access capability for all module devices.
Solution Approach 2:
The master device's physical Wifi component serves multiple functions: it provides network access for itself and simultaneously serves as a shared Wifi resource for multiple module devices. This multi-functionality eliminates the need for dedicated Wifi devices on each module device.
3Object-affected harmful factors
If Ethernet bridge is used to share Wifi component, then interference is reduced, but data transmission path becomes longer
Solution Approach 1:
The Ethernet bridge acts as an intelligent intermediary that manages data flow between the shared physical Wifi component and multiple module devices. Although it adds a transmission hop, it enables efficient wired Ethernet communication which can be more reliable and less interfered with compared to direct wireless communication between multiple devices.

AI summary
The disclosure relates to the field of communication, and particularly to a method, master device and module device for transmitting data via Wifi. In the embodiments of the disclosure, a virtual wireless network interface card is arranged in the module device, thus the Wifi data is transmitted via the Ethernet interface card and the Ethernet bridge, so that a wireless network interface card of a master device may be shared by a plurality of module devices, and the interference will not occur between the Wifi data of different module devices since the wifi data between the master device and the module device is transmitted by wire.
