Solution Overview

Problem

Current communication networks face challenges in providing high bandwidth and efficient data transmission, especially with the increasing demand from smartphones and other portable devices, as traditional macrocell base stations require higher bandwidth and existing wireless infrastructure struggles to meet this demand, and there is a need for innovative solutions to enhance broadband access networks.

Innovation Solution

A guided wave communication system that utilizes electromagnetic waves bound to or guided by transmission media such as wires or dielectric materials, allowing for efficient data transmission without the need for an electrical return path, using couplers and transceivers to launch and extract guided waves at millimeter-wave frequencies, and employing dielectric antennas for beam steering and propagation along power lines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional macrocell base stations are used to provide wireless coverage, then coverage area is large, but bandwidth capability is insufficient to meet increasing data demand

Engineering Contradiction:
Improvebandwidth capabilityVSAvoidcoverage area
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent divides the traditional macrocell network into multiple small cell nodes (microcells and picocells) that operate independently or cooperatively. Each small cell provides high-bandwidth service to a limited area, and multiple small cells collectively cover the entire service region, thus achieving both high productivity and adequate adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of network architecture by deploying small cells in three-dimensional space (indoor, outdoor, urban, rural) rather than relying solely on two-dimensional macrocell coverage. This multi-layered small cell architecture enables high bandwidth capability while maintaining comprehensive coverage through spatial distribution.

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

2Productivity

If existing wireless infrastructure is deployed to meet data demand, then infrastructure coverage is established, but it struggles to provide sufficient bandwidth for high-speed data transmission

Engineering Contradiction:
Improvedata transmission bandwidthVSAvoidservice reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent combines multiple small cell nodes with different coverage characteristics (microcells for urban areas, picocells for indoor environments) into an integrated heterogeneous network. This merging of different cell types and deployment scenarios creates a reliable high-bandwidth system that can adapt to various service conditions while maintaining overall service reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The small cell architecture serves multiple functions simultaneously: providing high-bandwidth data transmission, extending coverage to previously unserved areas, enabling both indoor and outdoor connectivity, and supporting diverse applications (voice, video, internet browsing). This multi-functionality achieves high productivity without compromising reliability.

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

3Adaptability or versatility

If broadband access networks are expanded to meet growing data usage, then network coverage increases, but bandwidth capacity becomes insufficient

Engineering Contradiction:
Improvenetwork coverageVSAvoidbandwidth capacity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the broadband access network into numerous small cell nodes distributed across the service area. Each node provides localized high-capacity bandwidth, and the aggregate capacity of all nodes delivers the required total bandwidth while maintaining extensive coverage through geographic distribution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes key network parameters by transitioning from few large macrocells to many small cells with different transmission powers, frequencies, and coverage radii. This parameter transformation enables the network to simultaneously achieve wide coverage and high bandwidth capacity by optimizing each small cell's operational characteristics for its specific environment.

Inventive Principle:
Principle #35Parameter changes
