Innovation Solution

A distributed access point system utilizing a control apparatus and spatially separated peripheral apparatuses, connected via high-frequency radio links between 52.6 GHz and 1 THz, to provide contemporaneous multipoint links with beamforming capabilities, dynamically reconfiguring radio links based on bandwidth, propagation conditions, and data rate needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple simultaneous radio links are provided to increase maximum bandwidth, then bandwidth is improved, but interference and congestion increase

Engineering Contradiction:
ImprovebandwidthVSAvoidinterference
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from traditional sub-6 GHz radio frequencies to millimeter wave frequencies (24 GHz to 1 THz), representing a dimensional change in the electromagnetic spectrum. This frequency dimension change enables multiple simultaneous radio links with higher bandwidth while the directional beamforming capability mitigates interference by spatially separating communication paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent changes key radio communication parameters including frequency (24 GHz to 1 THz), bandwidth (up to 400 MHz per link), and modulation schemes (up to 4096-QAM). These parameter changes enable higher data rates and multiple simultaneous links while beamforming controls the spatial distribution of energy to reduce interference.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If radio links use unlicensed frequencies such as 2.4 GHz and 5 GHz, then ease of operation is improved, but congestion and interference worsen

Engineering Contradiction:
Improveease of operationVSAvoidcongestion
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the operating frequency parameter from traditional unlicensed bands (2.4 GHz, 5 GHz) to millimeter wave unlicensed bands (24 GHz to 1 THz). This parameter change provides abundant spectrum resources with less congestion while maintaining ease of operation through automated beam management and dynamic resource allocation algorithms.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent exploits the unused millimeter wave dimension of the electromagnetic spectrum, which has been largely unexploited compared to traditional sub-6 GHz bands. This dimensional expansion provides abundant bandwidth resources while the directional nature of mmWave propagation naturally reduces co-channel interference and congestion.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If beamforming is used to provide spatially separated links, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improvedata rateVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic beamforming where beam directions, widths, and power levels are continuously adjusted based on channel conditions, user mobility, and traffic demands. The system dynamically selects from multiple beamforming codespaces and adapts modulation schemes (up to 4096-QAM) to optimize data rates while managing complexity through intelligent resource allocation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the radio interface into multiple independent spatial streams, each with its own beamforming chain and resource allocation. This segmentation allows parallel processing of multiple data streams through different spatial paths, improving overall productivity while distributing computational complexity across multiple manageable components.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If dynamic reconfiguration of radio links is performed, then adaptability is improved, but loss of time increases

Engineering Contradiction:
ImproveadaptabilityVSAvoidreconfiguration time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-configuring multiple beamforming codespaces, pre-establishing radio link connections, and pre-negotiating resource allocations before actual data transmission begins. This allows the system to rapidly adapt to changing conditions by switching between pre-prepared configurations rather than creating new ones from scratch, reducing reconfiguration time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous feedback mechanisms where channel quality indicators, beam performance metrics, and traffic demands are monitored in real-time. This feedback drives adaptive reconfiguration of beamforming parameters, modulation schemes, and resource allocations, enabling the system to adapt quickly to changing conditions while minimizing disruption to ongoing transmissions.

Inventive Principle:
Principle #23Feedback
