Solution Overview

Problem

First Responders often face communication disruptions in emergency situations due to inadequate mobile radio coverage within buildings, and existing solutions like portable communications networks are cumbersome and require security access codes, hindering real-time information sharing.

Innovation Solution

Implementing a system with universal encryption keys on Wi-Fi routers and Smart Repeater Units that allow authorized public safety devices to automatically connect to secure private or public Wi-Fi networks without requiring user input of security access codes, using preconfigured encryption keys and Smart Repeater Units that integrate with existing infrastructure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If portable communications networks are deployed to extend coverage, then communication coverage is improved, but device complexity and setup time increase

Engineering Contradiction:
Improvecommunication coverage areaVSAvoidportable network equipment complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent implements a universal encryption key system that enables public safety devices to access multiple different Wi-Fi networks without requiring separate authentication for each network. The preconfigured encryption keys allow a single device to universally connect to various secure networks (hotels, airports, cafes, private networks) that have been provisioned with the same key, eliminating the need for portable base stations and complex network equipment while extending communication coverage throughout the building.

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

2Reliability

If security access codes are required for Wi-Fi networks, then network security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvenetwork securityVSAvoidnetwork access convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by preconfiguring encryption keys on both the Wi-Fi networks and public safety devices before the emergency situation occurs. During an emergency, the preprovisioned keys enable automatic authentication and connection without requiring users to manually input security codes or passwords at the moment of need. This maintains security through preestablished credentials while dramatically improving ease of operation during critical situations.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If manual security code input is required, then access control is improved, but loss of time increases

Engineering Contradiction:
Improveaccess controlVSAvoidconnection setup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements self-service by enabling public safety devices to automatically authenticate and connect to Wi-Fi networks using preconfigured encryption keys. The system performs the authentication process autonomously without requiring manual code input from users. During emergencies, devices automatically utilize the preprovisioned keys to establish connections, maintaining access control security while eliminating time-consuming manual authentication steps.

Inventive Principle:
Principle #25Self-service

4Device complexity

If existing Wi-Fi infrastructure is used, then device complexity is reduced, but adaptability deteriorates

Engineering Contradiction:
Improvenetwork infrastructure simplicityVSAvoidnetwork access compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent enhances adaptability by implementing a universal encryption key system that allows public safety devices to access multiple types of Wi-Fi networks (hotels, airports, cafes, private networks) without requiring different equipment or configurations. The preprovisioned keys enable a single device to universally connect to various secure networks throughout the building, improving network access compatibility while maintaining simplicity by utilizing existing Wi-Fi infrastructure rather than deploying specialized equipment.

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

AI summary

Embodiments include a system, method, and computer program product for improving public safety communications and real-time information sharing to enable a public safety user to access available, secure private wireless communications (PWC) networks within a vicinity of an emergency for communications and data-sharing purposes. In an embodiment, a universal encryption key (UEK) is stored on a public safety access device. The public safety access device is providing access to a secure PWC network. The UEK is a key established by a certificate authority that enables public safety personnel to access the secure PWC network. Then, a public safety encryption key (PSKey) is received by the public safety access device from a user communication device. The public safety access device enables access for the user communication to access the secure PWC network upon a determination that the received PSKey is associated with the UEK.
