Solution Overview
Problem
Existing wireless mesh networks in rural areas face challenges such as high costs, limited bandwidth, and poor integration with the Internet, especially due to reliance on costly infrastructure and inefficient routing schemes that fail to adapt to dynamic radio resources and interference.
Innovation Solution
The implementation of a multi-hop wireless mesh network with adaptive transmission power control, dynamic routing, and real-time modulation and coding schemes, utilizing a combination of field programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs) to optimize communication protocols and network coding, while leveraging geographically distributed oil and gas equipment for power and stable connections.

Engineering Contradiction Analysis
1Reliability
If costly fixed infrastructure (cell towers) is deployed for wide-area coverage, then network access is provided, but the cost becomes prohibitively expensive
Solution Approach 1:
The network is segmented into multiple distributed nodes that relay information between end devices and Internet connections, replacing the monolithic cell tower infrastructure with a distributed mesh network of smaller, cheaper nodes
Solution Approach 2:
The mesh network nodes self-organize and relay data autonomously without requiring centralized control infrastructure, enabling the network to serve itself and reducing deployment costs
2Reliability
If existing wireless standards (WiFi, Zigbee, Bluetooth) are used for mesh networking, then network access is achieved, but bandwidth is limited and integration with Internet is poor
Solution Approach 1:
The system dynamically adapts transmission parameters including modulation schemes, coding rates, and transmission power based on real-time radio conditions to optimize bandwidth utilization across the mesh network
Solution Approach 2:
The patent changes physical layer parameters such as modulation type and coding scheme to adapt to varying channel conditions, enabling efficient data transmission over wireless mesh links with limited bandwidth
3Ease of operation
If established wireless spectrum is used for mesh network communication, then communication is enabled, but bandwidth is competed for with established uses (WiFi, cellular)
Solution Approach 1:
The system dynamically selects and adapts to available spectrum resources, adjusting transmission parameters in real-time to utilize unused or underutilized frequency bands and avoid congested channels
