Dual Gateway Data Transmission via Channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coupling wireless networks with wired networks poses challenges due to differences in radio frequencies and protocols, leading to data packet losses and duty cycle violations, which restricts fast and efficient data transmission.
Innovation Solution
A system comprising two devices, one connected to both networks, switches between two operating modes based on duty cycle checks to transmit data on different radio channels, ensuring that neither device exceeds its permissible usage, thereby maintaining efficient data transmission.

Engineering Contradiction Analysis
1Device complexity
If a single gateway transmits data on one radio channel, then the device complexity is reduced, but data packet losses increase when the gateway is transmitting a long telegram and a short telegram arrives simultaneously
Solution Approach 1:
The system divides the single gateway into two separate devices (first gateway device and second gateway device), each responsible for different radio channels. This segmentation eliminates the conflict where a single gateway cannot simultaneously handle transmissions on multiple channels, thereby preventing data packet losses while maintaining relatively simple device structures.
Solution Approach 2:
The wireless network acts as an intermediary between the two gateway devices and the wired network. This intermediary structure allows the two gateway devices to coordinate their transmissions through the wireless medium, enabling reliable data transmission without requiring direct complex inter-device communication protocols.
2Productivity
If a gateway transmits intensively on a specific frequency, then data transmission speed increases, but the device exceeds the permissible duty cycle
Solution Approach 1:
The system segments the transmission load across two gateway devices operating on different radio channels. Each device handles approximately half of the total traffic, which distributes the duty cycle burden and prevents any single device from exceeding permissible limits while maintaining high overall data transmission speed.
Solution Approach 2:
The system dynamically switches between two operating modes depending on which radio channel has available capacity. When one channel approaches its duty cycle limit, the system transitions to using the other channel, enabling continuous high-speed transmission while always complying with duty cycle regulations through adaptive load balancing.
3Productivity
If multiple devices transmit on different radio channels, then data transmission efficiency increases, but the system complexity and hardware requirements increase
Solution Approach 1:
Each gateway device is designed with multi-functionality, capable of operating on either the first or second radio channel and performing both transmission and reception functions. This universality allows the system to achieve high data transmission efficiency through channel diversity while keeping individual device configurations relatively simple and interchangeable.
