Multi-domain Network Centralized Signal Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network solutions face interference and resource allocation challenges due to the inability to simultaneously serve a sufficient number of nodes and provide sufficient throughput for modern services, leading to reduced performance and quality of service (QoS) due to crosstalk between different types of wired and wireless sub-networks.
Innovation Solution
A method for coordinating signals within a multi-domain network using a global master to manage frequency, time, and power coordination between domains, ensuring orthogonal signal usage and resource allocation to minimize interference and optimize QoS, employing mechanisms like frequency coordination, time coordination, and spatial coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple sub-networks utilize different types of wiring (phone lines, power lines, coax cable) to increase throughput, then network capacity and service variety are improved, but crosstalk between domains causes signal interference and reduces reliability
Solution Approach 1:
A centralized coordination entity acts as an intermediary between multiple network domains, managing resource allocation and signal coordination to prevent crosstalk while enabling high throughput across diverse wiring media
Solution Approach 2:
The system dynamically adjusts transmission parameters such as frequency allocation, power levels, and timing synchronization across different domains to minimize interference and optimize signal quality while maintaining high throughput
2Reliability
If domains use orthogonal signals over the same medium to avoid interference, then signal reliability is improved, but device complexity and coordination overhead increase
Solution Approach 1:
The centralized coordination entity provides universal resource management across all network domains, handling frequency allocation, power control, and timing synchronization through a single multi-functional system that reduces overall coordination complexity
3Area of stationary object
If transmission signals from one domain penetrate to another domain, then coverage area is improved, but harmful interference increases and erases victim network signals
Solution Approach 1:
The coordination entity preemptively allocates frequency resources and power levels to transmitting domains to prevent harmful penetration into victim domains, while still allowing beneficial signal propagation for coverage extension

AI summary
One embodiment relates to a method for coordinating signals within a multi-domain network. At least one node within one network domain of the multi-domain network is identified, where the one node is affected by interference due to another node of another network domain of the multi-domain network. Global signals are provided to the one network domain to coordinate domain signals within that network domain to limit the interference from the another node. Other systems and methods are also disclosed.
