VSEngineering Contradiction Analysis

1Adaptability or versatility

If preprogrammed iterative processes are used to adapt wireless communications parameters, then the system can automatically adjust parameters based on signal quality, but the adaptation is not optimized for specific compute environments leading to suboptimal performance

Engineering Contradiction:

Improveenvironment-specific parameter adaptationVSAvoidsignal quality and data transfer rate

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system uses spectral response deviation as feedback to identify compute environment types and adjusts wireless communications parameters accordingly. The spectral response appliance continuously monitors frequency-domain data and provides feedback about the compute environment, enabling the WAP device to adapt its parameters (modulation type, spatial stream quantity, guard interval) to achieve optimal performance for each environment type.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes wireless communications parameters such as modulation type, spatial stream quantity, and guard interval based on the identified compute environment type. By detecting spectral response deviations and categorizing environments (e.g., home, office, outdoor), the system dynamically modifies transmission parameters to optimize signal quality and data transfer rates for each specific environment.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If standard IEEE 802.11n protocol is followed without environmental awareness, then the system maintains simplicity and standard compliance, but signal quality and data rate are compromised due to lack of environmental adaptation

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The spectral response appliance acts as an intermediary between the WAP device and the compute environment. It collects frequency-domain data, analyzes spectral response deviations, and provides environment-type information to the WAP device. This intermediary enables the system to maintain standard protocol compliance while achieving environment-specific optimization through the spectral response appliance's analysis and recommendations.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Extent of automation

If traditional preprogrammed adaptive algorithms are used, then the system can perform automatic parameter adjustment, but it fails to account for multipath distortion and spectral characteristics specific to different compute environments

Core Design Contradiction:

Solution Approach 1:

The patent replaces traditional mechanical/preprogrammed adaptive algorithms with a spectral response-based analysis system. Instead of using fixed iterative algorithms, the system uses spectral response appliances to analyze frequency-domain data and identify compute environment types based on spectral characteristics. This substitution enables more precise adaptation by directly measuring spectral response deviations rather than relying on preprogrammed assumptions.

AI summary

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor includes code to cause the processor to receive from a wireless access point (WAP) device frequency-domain data associated with signals received at the WAP device from a wireless device during a time period. The code includes code to determine multiple frequency-domain magnitudes associated with the frequency-domain data for the time period to define a spectral magnitude signature associated with the frequency-domain data. Each frequency-domain magnitude from the multiple frequency-domain magnitudes is uniquely associated with a frequency bin from multiple mutually-exclusive frequency bins associated with the frequency domain data. The code also includes code to identify a spectral response deviation associated with the spectral magnitude signature and send a parameter indicator to the WAP device based on the spectral response deviation such that a wireless communications parameter value at the WAP device is changed.
