Solution Overview

Problem

Current ultrawideband (UWB) repeater technologies are inadequate for providing sufficient security, traffic filtering, bandwidth provisioning, and network management in rapidly proliferating UWB environments, which are prone to interference and security breaches, and require flexible and adaptive solutions to manage high data rates and multiple device connections without wiring.

Innovation Solution

A low-cost, adaptable UWB repeater device that extends the range of UWB piconets by selectively processing and filtering data, prioritizing traffic, and providing embedded security features, allowing for wireless and wired network integration, and real-time monitoring and reporting of network statistics, capable of ignoring undesired traffic and adapting to interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If UWB repeater technologies are used to extend communication range, then coverage distance is improved, but security and traffic filtering capabilities deteriorate

Engineering Contradiction:
Improvecommunication rangeVSAvoidsecurity
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

The repeater performs preliminary authentication and authorization checks on incoming packets before retransmission. The security module verifies source addresses, destination addresses, and packet types against pre-configured security policies, blocking unauthorized traffic before it can compromise the network. This preliminary security action ensures that extended coverage does not compromise network security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The repeater acts as an intermediary device between transmitting and receiving devices, inserting security filtering and traffic management functions into the communication path. The security module mediates packet flow, selectively allowing or blocking traffic based on authentication results and security policies, thus protecting the extended network from security threats while maintaining communication range.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Length of stationary object

If UWB repeater technologies are used to extend communication range, then coverage distance is improved, but interference resistance deteriorates

Engineering Contradiction:
Improvecoverage distanceVSAvoidinterference
Core Design Contradiction:
Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The repeater dynamically adjusts transmission parameters including power levels, modulation schemes, and frequency hopping patterns based on detected interference conditions. The controller monitors packet error rates and signal quality, modifying transmission parameters in real-time to maintain reliable communication over extended distances despite interference from other UWB devices or environmental factors.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The repeater implements periodic carrier sense multiple access (CSMA) listening before retransmission, and periodically updates security policies and authentication credentials. This periodic action allows the system to adapt to changing interference conditions and maintain secure, reliable communication across the extended coverage area.

Inventive Principle:
Principle #19Periodic action

3Device complexity

If basic repeater functionality is implemented, then device complexity is reduced, but network management capabilities deteriorate

Engineering Contradiction:
Improverepeater structureVSAvoidnetwork management
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The repeater is designed as a multi-functional device that simultaneously provides signal amplification, security filtering, traffic prioritization, bandwidth provisioning, and network management capabilities. The controller executes multiple protocols including authentication, authorization, accounting (AAA), and quality of service (QoS) management, allowing a single device to perform numerous network functions without proportionally increasing complexity.

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

Solution Approach 2:

The patent combines security module, traffic filtering, bandwidth provisioning, and network management functions into a single integrated repeater device. By merging these previously separate functions into one unit, the system achieves comprehensive network management capabilities while avoiding the complexity of multiple separate devices or complex distributed control architectures.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If security filtering and traffic prioritization are implemented, then network security is improved, but device complexity increases

Engineering Contradiction:
Improvenetwork securityVSAvoidrepeater structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The repeater implements self-service security mechanisms including automatic authentication of transmitting devices, dynamic policy updates from remote servers, and autonomous traffic filtering based on pre-configured rules. The controller automatically manages security credentials and updates authorization policies without manual intervention, reducing operational complexity while maintaining high security standards.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback loops where the controller monitors network traffic patterns, authentication successes/failures, and security events, then dynamically adjusts filtering rules and security policies. This feedback mechanism allows the repeater to adapt to emerging security threats automatically, maintaining high security with minimal manual configuration complexity.

Inventive Principle:
Principle #23Feedback
