Solution Overview

Problem

Existing data radio communication networks using radio communication infrastructures face inefficiencies due to the need for substantial bandwidth and lack of spatial redundancy, particularly in narrow frequency bands like the ISM and ERC 70-03 bands, leading to channel congestion and interference.

Innovation Solution

An intelligent network dynamically selects the best-received access point for each communicating radio device based on uplink and downlink quality, using a selection algorithm that considers variables such as reception levels, feedback periods, and message success rates to optimize communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated communication channels are allocated for each radio device, then communication reliability is improved, but bandwidth consumption increases significantly

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidbandwidth consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

Multiple access points are merged into a coordinated system that serves multiple radio devices simultaneously. The access points work together as a unified network infrastructure, sharing the available bandwidth through coordinated transmission and reception operations, thereby reducing total bandwidth consumption while maintaining communication reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Each access point is designed with multi-functionality, serving not only its associated radio devices but also participating in network-wide operations such as relay communications, interference management, and collaborative signal processing. This universal functionality allows efficient utilization of limited bandwidth resources across the entire network.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple channels are used for data transmission, then data throughput is improved, but channel congestion and interference increase

Engineering Contradiction:
Improvedata throughputVSAvoidchannel congestion and interference
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The system implements continuous feedback mechanisms where access points monitor channel conditions, interference levels, and transmission success rates. Based on this feedback, the network dynamically adjusts transmission parameters, channel assignments, and power levels to optimize data throughput while minimizing congestion and interference effects.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The network employs dynamic channel allocation and transmission parameter adjustment rather than static configurations. Access points and radio devices adapt their communication strategies in real-time based on changing network conditions, allowing the system to maintain high throughput while dynamically avoiding congestion and interference.

Inventive Principle:
Principle #15Dynamics

3Reliability

If radio devices transmit at full power to ensure reception, then signal quality is improved, but energy consumption increases

Engineering Contradiction:
Improvesignal qualityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of uniform full-power transmission across the network, each radio device transmits at locally optimized power levels based on its specific distance to access points, environmental conditions, and channel quality. This localized power adjustment ensures sufficient signal quality for reliable communication while minimizing unnecessary energy consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses partial power transmission rather than always transmitting at full power. Radio devices transmit at the minimum necessary power level required to achieve acceptable signal quality, using full power only when absolutely necessary for maintaining communication reliability under challenging conditions.

Inventive Principle:
Principle #16Partial or excessive action

4Area of stationary object

If access points are densely deployed to improve coverage, then network coverage is improved, but device complexity and coordination difficulty increase

Engineering Contradiction:
Improvenetwork coverageVSAvoidcoordination complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The network is segmented into multiple independently manageable access point units, each capable of autonomous operation within its local area. This segmentation allows dense deployment for improved coverage while keeping individual device complexity low, as each access point handles only its local communications and coordinates through standardized protocols with the central controller.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A central controller or coordinator acts as an intermediary between densely deployed access points, managing coordination and resource allocation. This intermediary simplifies the interaction complexity between access points by providing centralized management, allowing dense deployment for improved coverage without proportionally increasing coordination difficulty.

Inventive Principle:
Principle #24Intermediary (Mediator)
