Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems are vulnerable to jamming, which can compromise security measures like alarm systems and theft protection units, as existing methods fail to reliably send messages to remote centers during jamming conditions, especially requiring a second, wired connection.
Innovation Solution
The method involves a wireless device configured for enhanced coverage mode, which repeats signals to aggregate sufficient power for decoding, allowing it to switch to an enhanced coverage base station and send a jamming indication message to a remote server via the cellular network, even in jammed conditions, utilizing LTE-Cat1 technology and 3GPP Release 13 definitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless device uses conventional wireless communication to send alarm messages, then the device can communicate with remote centers, but the communication can be blocked by jamming signals
Solution Approach 1:
The wireless device performs preliminary actions by detecting jamming conditions and switching to enhanced coverage mode before the jamming completely blocks communication. The device pre-configures alternative communication paths and prepares backup mechanisms to maintain connectivity despite jamming attempts.
Solution Approach 2:
The system changes operational parameters by switching from conventional coverage mode to enhanced coverage mode, which modifies signal reception parameters to filter out jamming signals and identify legitimate base stations through specific signal characteristics and geographic validation.
2Reliability
If a wireless device switches to enhanced coverage mode to overcome jamming, then communication reliability improves, but the device complexity increases
Solution Approach 1:
The wireless device is designed with multi-functionality, supporting both conventional coverage mode and enhanced coverage mode within a single device. This universal design allows the device to handle different communication scenarios without requiring separate devices, thereby managing complexity through integrated functionality.
Solution Approach 2:
The system dynamically adapts between different coverage modes based on real-time conditions. The device can switch between conventional and enhanced coverage modes depending on signal quality and jamming detection, providing flexible operation that manages complexity through adaptive behavior rather than fixed configurations.
3Reliability
If the wireless device uses enhanced coverage mode with signal repetition, then signal decoding capability improves in jammed conditions, but the time to establish communication increases
Solution Approach 1:
The device performs preliminary detection of jamming conditions and prepares the enhanced coverage mode configuration in advance. By detecting jamming early and pre-configuring the alternative mode, the device minimizes the time needed to switch and establishes communication more quickly compared to reacting after complete signal failure.
