Virtual Ethernet Interface for Wireless Protocol Abstraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing applications for low bandwidth wireless interfaces like ZigBee, Bluetooth, and Z-Wave is burdensome due to the need to handle different vendor-specific protocols, increasing development costs and complexity.
Innovation Solution
Abstracting wireless devices to a virtual Ethernet interface, allowing applications to communicate using a unified Ethernet protocol, independent of the interface technology or vendor, by creating a virtual Ethernet interface and associating it with a wireless device ID, and separating control and data paths to handle network packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If applications directly use different wireless interface protocols (ZigBee, Bluetooth, Z-Wave), then vendor-specific functionality is achieved, but application development complexity and cost increase
Solution Approach 1:
The patent introduces a virtual Ethernet interface as an intermediary layer between wireless devices and applications. This virtual interface translates vendor-specific wireless protocols into standard Ethernet frames, allowing applications to communicate with diverse wireless devices using a unified protocol without needing to understand underlying protocol differences
Solution Approach 2:
The virtual Ethernet interface provides a universal communication layer that works with multiple wireless technologies (ZigBee, Bluetooth, Z-Wave, Wi-Fi). By presenting a common Ethernet interface for all wireless devices, the system achieves multi-functionality where a single application can interact with any wireless device type through the same interface
2Adaptability or versatility
If applications handle multiple wireless protocols directly, then support for different vendors is achieved, but development time and resource requirements increase
Solution Approach 1:
The virtual Ethernet interface acts as a mediator that handles protocol translation and vendor-specific interactions, freeing application developers from implementing multiple protocol stacks. The system absorbs the complexity of vendor compatibility requirements in the intermediary layer rather than in each application
Solution Approach 2:
The patent creates a virtual copy of the wireless interface that emulates standard Ethernet behavior. Instead of requiring applications to directly handle diverse wireless protocols, the system creates a simplified virtual representation that mirrors Ethernet functionality, reducing development time by eliminating the need to implement multiple protocol handlers
3Device complexity
If a unified Ethernet interface is implemented for wireless devices, then development complexity is reduced, but protocol translation overhead is introduced
Solution Approach 1:
The patent extracts the protocol translation functionality from the application layer and places it in the virtual Ethernet interface layer. This separation allows applications to remain simple while the translation overhead is handled by the dedicated virtual interface component, isolating the complexity to a specific system component rather than distributing it across all applications

AI summary
A wireless interface system includes a wireless network interface, with a virtual Ethernet interface, that is configured to transmit and receive signals over a wireless channel using a predetermined wireless technology protocol. A method for abstracting a wireless interface protocol to an Ethernet protocol includes detecting, with a wireless network interface, access by a wireless device using the wireless interface protocol. A virtual Ethernet interface is created having an associated Ethernet interface ID. The wireless device ID is associated with the Ethernet interface ID in a table in memory. A payload from the wireless device is transmitted over the wireless technology protocol. The payload is transmitted to the virtual Ethernet interface using the Ethernet protocol.
