Solution Overview

Problem

Wireless communication systems face challenges in maintaining clear line-of-sight (LOS) conditions between nodes, especially in areas with moderate to high vegetation, leading to link failures and network disruptions.

Innovation Solution

The use of non-penetrating mounting apparatuses for wireless communication nodes, which employ a distributed weight system with support struts to secure nodes on rooftops without damaging the surface, and the implementation of phased array antennas with beam steering capabilities to adjust radiation beams and maintain LOS.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If penetrative mounting methods are used to secure wireless communication nodes on rooftops, then mounting stability is improved, but rooftop structural integrity deteriorates

Engineering Contradiction:
Improvemounting stabilityVSAvoidrooftop structural integrity
Core Design Contradiction:
Stability of the object's compositionVSStrength

Solution Approach 1:

The mounting apparatus uses counterweights that can be adjusted to balance the weight of the wireless communication node, distributing the load away from penetrative points and reducing stress on the rooftop structure while maintaining mounting stability

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The mounting system transitions from a two-dimensional surface mount to a three-dimensional distributed weight system using adjustable counterweights and support struts, creating multiple load paths that reduce concentrated stress on the rooftop

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

2Reliability

If field technicians are dispatched to fix LOS issues by re-aligning wireless mesh communication network radios, then communication connectivity is restored, but time and labor costs increase

Engineering Contradiction:
Improvecommunication connectivityVSAvoidtime and labor costs
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The wireless communication node is equipped with self-diagnostic and self-adjustment capabilities that automatically detect LOS issues and adjust the antenna alignment or activate alternative communication paths without requiring field technician intervention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback monitoring of LOS conditions and automatically triggers adjustment mechanisms or alternative routing when degradation is detected, maintaining communication reliability without manual intervention

Inventive Principle:
Principle #23Feedback

3Area of stationary object

If wireless communication nodes are deployed in areas with moderate to high vegetation, then network coverage is expanded, but LOS conditions deteriorate

Engineering Contradiction:
Improvenetwork coverage areaVSAvoidLOS conditions
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The mounting apparatus incorporates adjustable and movable components that allow real-time repositioning of wireless communication nodes to maintain optimal LOS conditions as vegetation grows or environmental conditions change, preserving both coverage area and reliability

Inventive Principle:
Principle #15Dynamics

AI summary

A given wireless communication node of a wireless mesh network may include at least one processing unit and a plurality of radio modules, where at least one given radio module of the plurality of radio modules is capable of operating in a temporary network-sensing mode in which the given radio module gathers information about any other wireless communication node of the wireless mesh network that is sensed within the given wireless communication node's surrounding area by scanning for radio-frequency signals being emitted by any other radio module within at least a portion of the given wireless communication node's surrounding area while an antenna azimuth of the given radio module is being rotated.
