Solution Overview

Problem

Radio congestion occurs due to neighboring wireless networks using the same radio channels, leading to performance issues in security systems and other wireless networks.

Innovation Solution

A cloud-based radio survey service that analyzes interference scores across different channels, allowing wireless devices to switch to the least congested channel, eliminating the need for specialized equipment and training, and enabling real-time, cost-effective channel selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a cloud-based radio survey service is implemented, then channel selection becomes automated and accessible without specialized equipment, but system complexity increases due to cloud service integration

Engineering Contradiction:

Improvechannel selection accessibilityVSAvoidsystem architecture complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

A cloud-based intermediary service is introduced to perform radio surveys and channel analysis. The cloud service acts as a mediator between wireless devices and channel selection, receiving survey data from devices and returning optimized channel recommendations without requiring complex local processing equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical/radio frequency survey equipment with a software-based cloud service. Instead of using specialized hardware to conduct radio surveys and analyze interference, the system uses internet-connected devices to submit surveys to a cloud platform that performs the analysis and returns channel recommendations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If remote channel selection is implemented without on-site technicians, then service cost and time are reduced, but measurement and detection accuracy may be compromised

Engineering Contradiction:

Improvechannel selection timeVSAvoidradio survey accuracy

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

Wireless devices perform self-service by automatically conducting radio surveys and submitting the data to the cloud service. The devices themselves gather the necessary measurement data without requiring external technician intervention, enabling remote channel selection while maintaining measurement accuracy through automated data collection.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback mechanism where the cloud service analyzes survey data and returns channel recommendations to the wireless devices. This closed-loop feedback ensures that channel selections are based on accurate analysis of current radio conditions, maintaining measurement precision even without on-site technicians.

Inventive Principle:

Principle #23Feedback

AI summary

A web-based radio survey service is provided to client devices. The client devices individually conduct a radio survey. The radio surveys are sent to a central server for analysis. The central server evaluates the radio surveys and determines a least congested radio channel for common use by all the client devices. The client devices may thus all switch to the least congested radio channel to ensure reliable radio service with an access device.
