Wireless Access Point Tessellation for Multi-Unit Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network deployment methods in multi-unit buildings result in signal bleed and interference between units, compromising privacy and security, and limit control of wireless devices beyond the coverage area of an individual access point.
Innovation Solution
The method involves strategically placing access points in a tessellated grid, using non-overlapping channels and adjustable power levels and antenna beam patterns to create distinct wireless cells that minimize interference and ensure coverage without compromising privacy, allowing users to maintain control over devices across multiple units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wireless router is placed in each individual unit to provide coverage, then coverage area is improved, but signal interference and privacy security are worsened
Solution Approach 1:
The system segments the wireless network into multiple virtual networks (VLANs) that are logically separated at the data link layer. Each unit's wireless traffic is segmented into its own virtual network, preventing signal bleed and interference between neighboring units while maintaining physical infrastructure efficiency. The access points broadcast multiple SSIDs corresponding to different VLANs, allowing units to join appropriate virtual networks without physical isolation.
Solution Approach 2:
The patent introduces a virtual dimension (VLAN tagging) over the physical wireless medium. By adding VLAN identifiers to wireless frames, the system creates logical separation in the data link layer without requiring physical separation of access points or wireless cells. This dimensional addition allows multiple isolated networks to coexist on the same physical infrastructure.
2Area of stationary object
If a wireless router is placed in each individual unit to provide coverage, then coverage area is improved, but device complexity is worsened
Solution Approach 1:
The system merges multiple virtual networks onto a single physical access point infrastructure. Instead of requiring separate access points for each unit, the patent combines multiple VLAN-capable access points that can handle multiple SSIDs and VLAN tags simultaneously. This consolidation reduces the total number of physical devices while maintaining network isolation and coverage.
3Ease of manufacture
If access points use standard coverage areas, then ease of deployment is improved, but user control beyond coverage area is worsened
Solution Approach 1:
The system implements dynamic VLAN assignment and roaming capabilities that allow users to maintain network connectivity and device control as they move between physical locations. Users can be dynamically assigned to appropriate VLANs based on their location or device, and the system maintains session continuity across access point boundaries, enabling control beyond any single access point's coverage area.
