Hybrid Mesh Backhaul Tunneling for Out-of-Range Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mesh networks are limited to communicating with devices within their signal range, lacking the ability to extend communication range and maintain reliability when nodes move out of range or form separate networks, and they cannot bypass firewalls for internet connectivity.
Innovation Solution
Establishing tunnels between backhaul nodes of different mesh networks and a server to encapsulate packets, enabling communication beyond signal range and firewall bypass, using a hybrid mesh network architecture with internet-connected backhaul nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mesh networks rely solely on direct node-to-node communication within signal range, then network simplicity is maintained, but communication range is limited and reliability decreases when nodes move out of range
Solution Approach 1:
The patent introduces a server as an intermediary component that enables mesh networks to communicate through relay nodes. When nodes are out of direct signal range, packets are routed through the server via backhaul nodes, ensuring reliable communication while maintaining the simplicity of individual node operations. The server acts as a mediator that bridges disconnected mesh segments without requiring complex routing protocols at each node.
2Adaptability or versatility
If mesh networks operate without internet connectivity, then network independence is maintained, but inability to bypass firewalls prevents external communication
Solution Approach 1:
The patent implements backhaul nodes that serve multiple functions: they operate as regular mesh nodes for local communication, serve as relay points for extending network range, and function as firewall-bypassing proxies for internet traffic. This multi-functionality allows the same node type to handle diverse communication scenarios without requiring complex configuration, as the server automatically manages routing decisions based on packet destinations.
3Reliability
If packets are encapsulated through backhaul nodes and server to bypass firewalls and extend range, then communication range and reliability improve, but packet transmission path complexity increases
Solution Approach 1:
The patent implements self-service routing where individual mesh nodes automatically determine whether to forward packets through the server based on simple criteria (destination address). The server autonomously manages encapsulation, routing decisions, and firewall bypass logic without requiring manual configuration. This self-service approach simplifies the overall system by eliminating complex centralized control while maintaining reliable packet delivery through the encapsulation tunnel.

AI summary
Techniques include establishing a first tunnel that transmits a first packet between a first backhaul node of a first local mesh network and a server. The techniques further include, responsive to the second backhaul node moving out of wireless communication range of the first local mesh network, establishing a second tunnel that transmits packets between the second backhaul node of a second local mesh network and the server. The techniques further include receiving the first packet from the first backhaul node in the first local mesh network transmitting the first packet to the second backhaul node.
