Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The expansion of upstream bandwidth in cable networks to meet the increasing demand for interactivity-intense applications is hindered by signal leakages and interferences due to imperfect isolation of upstream and downstream bandwidth, leading to costly and disruptive hardware installations and service interruptions.
Innovation Solution
A system and method for upgrading upstream bandwidth on a per-home basis using remote monitoring and analysis tools to assess device performance, enabling mid-split or high-split deployments without disrupting ongoing services, by identifying and addressing potential interference issues through remote controlling and monitoring tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If upstream bandwidth is expanded to meet higher demand, then bandwidth capacity is improved, but signal leakages and interferences occur due to imperfect isolation
Solution Approach 1:
The system performs preliminary monitoring and analysis of test signals from devices before expanding upstream bandwidth. This includes assessing device performance, evaluating isolation characteristics, and determining whether devices will be negatively impacted by bandwidth expansion, thereby preventing signal leakage and interference issues before they occur
Solution Approach 2:
The system continuously monitors device performance metrics and upstream signal characteristics after bandwidth expansion. Based on this feedback, the system can identify signal leakage and interference issues and perform troubleshooting to address them, ensuring quality of service is maintained
2Quantity of substance
If hardware equipment is installed to expand upstream bandwidth, then bandwidth capacity is improved, but operational costs increase and service disruptions occur
Solution Approach 1:
The system enables self-service deployment of upstream bandwidth expansion by using automated monitoring and analysis tools to assess device compatibility and performance. This eliminates the need for costly on-site technician visits and hardware installations at customer premises, as the expansion is achieved through software-based band split configuration and remote device management
Solution Approach 2:
The system replaces physical hardware installation and mechanical troubleshooting with remote electronic monitoring and software-based device management. Test signals and performance metrics are analyzed electronically to determine bandwidth expansion feasibility, eliminating the need for physical equipment installation and on-site service interruptions

AI summary
Systems, apparatuses, and methods are described for deploying upstream bandwidth upgrade of devices per home basis. The impact of the upstream bandwidth upgrade on the devices may be pre-estimated based on remotely monitoring and/or analyzing performance data of the devices collected during transmissions of test signals (e.g., a burst of upstream transmissions) in real-time from the devices operating under different modes of operations. The burst of upstream transmissions using a small bandwidth (e.g., 1.6 MHz) may be limited to a short duration of time (e.g., 5 seconds) so that on-going services provided by the devices are not substantially interrupted. The upstream bandwidth of the devices, based on the pre-estimated impact, may be upgraded, left unaltered, or downgraded.
