Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networking devices face interference and crosstalk issues when operating in both ad-hoc and infrastructure modes simultaneously due to the close proximity of dual wireless network cards, leading to increased signal-to-noise ratio and conflicts in receiving channels.
Innovation Solution
A state machine with a dual MAC core that can concurrently support both wireless networking modes, allowing for switching between ad-hoc and infrastructure processes, and optionally over-clocking to manage increased load, implemented either in hardware or software, to handle both types of wireless signals and processes efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual wireless network cards are used to support both ad-hoc and infrastructure modes, then both wireless networking modes can be supported simultaneously, but interference and crosstalk issues occur due to close proximity of the cards
Solution Approach 1:
The patent merges the functionality of two separate wireless network cards into a single integrated wireless network card that can operate in both ad-hoc and infrastructure modes simultaneously. This consolidation eliminates the physical proximity issue between separate cards while maintaining dual-mode capability through integrated hardware and software management.
Solution Approach 2:
The single wireless network card is designed with multi-functionality to support both ad-hoc and infrastructure modes. The card incorporates dual MAC cores that can independently handle different wireless protocols and modes, allowing one device to perform multiple functions that previously required separate cards.
2Adaptability or versatility
If two physical network links are used to support concurrent ad-hoc and infrastructure modes, then both modes can operate independently, but device complexity and cost increase
Solution Approach 1:
The patent combines two physical network links into a single integrated wireless network card with dual MAC cores. This merging reduces hardware complexity while maintaining the capability to operate in both ad-hoc and infrastructure modes concurrently through software-based virtualization and resource management.
Solution Approach 2:
The single wireless network card is designed as a universal device that can function as both ad-hoc and infrastructure interfaces simultaneously. The dual MAC cores provide independent processing paths for each mode, enabling one physical device to replace what previously required two separate network links.
3Device complexity
If a single MAC core is used to switch between ad-hoc and infrastructure modes, then device complexity is reduced, but concurrent execution of both modes is not possible
Solution Approach 1:
The patent segments the MAC layer functionality into two independent MAC cores within a single wireless network card. Each MAC core is dedicated to handling specific wireless modes or protocols, allowing concurrent execution without interference. This segmentation enables parallel processing while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent transitions from a single-threaded MAC core model to a multi-core parallel architecture. By adding the dimension of parallel processing with multiple MAC cores, the system can simultaneously handle both ad-hoc and infrastructure modes without the temporal switching limitations of a single core, thereby enabling true concurrent execution.

AI summary
The present invention relates to a state machine which has a dual process which receives and concurrently processes ad-hoc and infrastructure processes. The dual process state concurrently executes both processes by either over-clocking a media access control core, or by routing the processes to multiple media access control cores for processing. The state machine contains an ad-hoc process state which accepts either an ad-hoc or an infrastructure signal, and either processes the signal if the received signal is an ad-hoc signal, or transfers control to an infrastructure process state for processing if the received signal is an infrastructure signal. The state machine also contains an infrastructure process state which accepts either an ad-hoc or an infrastructure signal, and either processes the signal if the received signal is an infrastructure signal, or transfers control to an ad-hoc process state for processing if the received signal is an ad-hoc signal.
