Solution Overview

Problem

The existing physical access requirements for installing and maintaining optical fiber infrastructure in buildings are costly, labor-intensive, and inconvenient, hindering the deployment of high-speed communications due to the need for drilling through walls and obtaining multiple site authorizations.

Innovation Solution

A passive optical network system utilizing wireless transceivers to connect outdoor optical line termination (OLT) to indoor optical network terminal (ONT) without physical fiber penetration, enabling bi-directional data transmission across building partitions, thus eliminating the need for physical access and reducing installation costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical fiber penetration through building walls is implemented, then reliable optical connection is achieved, but installation cost and complexity increase significantly

Engineering Contradiction:

Improveoptical connection reliabilityVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical drilling and physical fiber installation process with a wireless optical communication system. Instead of physically penetrating walls with fiber cables, the system uses wireless transceivers that communicate through the building structure, eliminating the need for mechanical drilling, cable routing, and physical connection while maintaining reliable data transmission

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces wireless transceivers as intermediary devices that bridge the optical network to indoor equipment without direct physical fiber connection. These transceivers act as mediators that convert optical signals to wireless signals for transmission through building walls, and then convert back to optical signals for indoor distribution, eliminating the need for direct fiber penetration

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If physical access to subscriber premises is obtained, then fiber installation is enabled, but deployment time and labor cost increase

Engineering Contradiction:

Improvedeployment easeVSAvoiddeployment time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent replaces the mechanical process of physical access, drilling, and fiber installation with wireless transceiver deployment. The wireless transceivers can be mounted on exterior walls without requiring entry into the premises, eliminating time-consuming activities such as obtaining access authorization, scheduling installations, drilling holes, routing cables, and making physical connections

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple site access authorizations are obtained, then fiber installation permission is secured, but administrative overhead and cost increase

Engineering Contradiction:

Improveinstallation permissionVSAvoidadministrative complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the fiber installation process from the subscriber premises interior to the exterior wall surface. By placing wireless transceivers on the outside of building walls, the system eliminates the need to obtain access authorizations from apartment owners, building owners, or property management, as no entry into the premises is required

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If physical fiber installation is performed, then network connectivity is established, but subscriber inconvenience and disturbance occur

Engineering Contradiction:

Improvenetwork connectivityVSAvoidsubscriber convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the intrusive mechanical installation process with a non-intrusive wireless system. The wireless transceivers are mounted on exterior walls without requiring entry into the subscriber's home, eliminating disturbances such as noise from drilling, dust generation, disruption of daily activities, and potential damage to property

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method and system implementations thereof include receiving data from a passive optical network (PON) outside a building; wirelessly transmitting the received PON data to inside the building; and applying the received PON data to a network inside the building. The data received outside the building is from an optical line termination (OLT). The PON data wireless transmitted inside the building may be applied to an optical line terminal (ONT) inside the building. Alternatively, the wirelessly received PON data may be converted to Ethernet format and applied to a user interface and/or a gateway interface all inside the building. The wireless transmission of PON data may be via a first transceiver mounted on a surface outside the building and a second transceiver mounted on a surface inside the building. The surface may be a corridor, a window, a door, a walls and a façade.
