Jamming Boundary for Wireless Security Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network security is compromised due to unauthorized access and information leakage, as existing methods like user authentication and data encryption are insufficient in preventing external hacking and unintentional connections.
Innovation Solution
A wireless communication system that employs a jammer to create a controlled communication area by generating noise, forming a jamming boundary that divides the communication area between an access point and a terminal, using the signal-to-noise ratio to determine the boundary's position and size, effectively isolating the secure zone from external interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication and data encryption methods are used to prevent unauthorized access, then security is improved, but information leakage still occurs in subsequent cases
Solution Approach 1:
The patent converts the harmful effect of electromagnetic noise into a beneficial security mechanism. By introducing a jammer that generates noise to block unauthorized access, the system transforms what would normally be interference into a controlled boundary that prevents information leakage while allowing authorized communication to proceed uninterrupted.
Solution Approach 2:
The jammer acts as an intermediary element between the access point and external terminals. It creates a controlled electromagnetic barrier that mediates the interaction, allowing authenticated users to communicate freely while blocking unauthenticated access attempts, thus preventing information leakage without affecting legitimate traffic.
2Reliability
If physical perimeter isolation is implemented to prevent external access, then security is improved, but the system loses flexibility and adaptability
Solution Approach 1:
The patent implements dynamic geographical control of communication areas through adjustable jamming boundaries. The boundary position and coverage area can be dynamically modified based on operational requirements, allowing the system to adapt to different security needs and geographical configurations without implementing fixed physical perimeters.
Solution Approach 2:
The system changes parameters such as jamming power level, boundary position, and coverage radius to control the communication area. By adjusting these parameters, the system can flexibly define secure zones, expand or contract coverage, and adapt to different deployment scenarios without physical infrastructure changes.
3Reliability
If jamming power is increased to strengthen the secure zone, then security is improved, but the communication area shrinks and legitimate users are affected
Solution Approach 1:
The patent applies local quality by creating different electromagnetic environments in different spatial regions. The jamming boundary establishes a clear division where high noise power blocks unauthorized access in external areas while maintaining clean signal reception in the internal secure zone, allowing authorized users to communicate without interference.
Solution Approach 2:
The system performs preliminary action by pre-establishing the jamming boundary before unauthorized access attempts occur. The boundary is set in advance to define the secure zone, and the jammer is activated only when needed to enforce the boundary, preventing unauthorized access while minimizing impact on legitimate users who are already authenticated.

AI summary
A wireless communication system for geographically controlling a communication area includes an access point for communicating with a terminal in a first area, and a jammer for generating noise for intercepting communication between the access point and a terminal in a second area. A jamming boundary for dividing an area in which the terminal can communicate with the access point and an area in which the terminal cannot communicate with the access point in an area in which the first area and the second area are overlapped is formed, and the jamming boundary is formed by a ratio between power of a signal transmitted to the terminal by the access point and power of a signal of the noise.
