Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi networks face challenges such as unstable connections, congestion, and interference, particularly in areas with weak coverage or high device density, leading to reduced data speeds and connectivity issues, which existing solutions like Wi-Fi extenders are not scalable or cost-effective.
Innovation Solution
A mesh gate node with both AP and mesh interfaces is used to manage communications between Wi-Fi and mesh networks, dynamically activating AP mode for probe requests and utilizing mesh interfaces for network connectivity, enabling efficient communication through integrated beacons and adaptive MCS indexing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If Wi-Fi extenders are used to improve coverage in weak signal areas, then network coverage is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements multi-functionality by enabling mesh nodes to dynamically switch between AP mode and mesh mode. A single node can serve both as an access point for direct client connections and as a mesh relay for extending coverage, eliminating the need for separate Wi-Fi extender devices and reducing overall network complexity while expanding coverage area
Solution Approach 2:
The patent applies dynamics through dynamic mode switching where mesh nodes can transition between AP mode and mesh mode based on real-time network conditions. This dynamic adaptation allows the network to optimize performance and coverage without adding permanent infrastructure, resolving the contradiction between coverage expansion and device complexity
2Reliability
If mesh nodes transmit beacons at every beacon interval to ensure network discovery and synchronization, then network reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by allowing mesh nodes to transmit beacons at configurable intervals rather than continuously. Nodes can adjust beacon transmission frequency based on network conditions and power availability, maintaining reliable network discovery and synchronization while significantly reducing energy consumption compared to continuous beaconing
Solution Approach 2:
The patent applies partial action by having only certain mesh nodes (such as root nodes or gateway nodes) transmit beacons at full intervals, while other nodes can reduce or skip beacon transmissions when network conditions permit, thereby maintaining overall network reliability with reduced total energy consumption across the mesh
3Area of stationary object
If multiple mesh nodes are deployed to extend network coverage, then coverage area is improved, but network congestion and interference worsen
Solution Approach 1:
The patent applies segmentation by dividing the mesh network into multiple independent Basic Service Sets (BSS), each managed by a root mesh node. This segmentation allows traffic to be distributed across multiple BSS boundaries, reducing congestion within individual segments and minimizing interference between nodes while collectively covering a larger geographic area

AI summary
Systems and techniques are provided for performing wireless communications. In some aspects, a mesh gate includes an access point (AP) interface and a mesh interface, and can monitor a sub-gigahertz wireless radio channel for probe requests. An AP mode of the mesh gate can be activated to turn on the AP interface based on receiving a probe request from a station (STA) in a Basic Service Set (BSS). The mesh gate can wirelessly connect to and perform communications with the STA using the AP interface. The mesh gate can perform communications with one or more mesh nodes in a mesh BSS using the mesh interface, wherein the mesh gate node is configured to provide communications between the STA and the one or more mesh nodes via an interconnection between the AP interface and the mesh interface.
