Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in diagnosing and addressing issues within their components efficiently, as existing methods require labor-intensive on-site analysis and are not proactive in preventing performance degradation over time.
Innovation Solution
Implementing spectrum analysis (SA) capabilities in communication devices to generate and share SA information, allowing for distributed processing and identification of operational trends, failures, or degradations across the system, enabling proactive maintenance and adaptive performance mitigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If service personnel conduct on-site analysis at multiple locations, then diagnosis accuracy is improved, but labor cost and time consumption increase significantly
Solution Approach 1:
The patent implements spectrum analysis capability in communication devices (cable modems, set-top boxes) to generate copies of spectrum analysis information locally at each location. This eliminates the need for service personnel to physically visit each location with expensive spectrum analyzers, as the diagnostic data is automatically captured and transmitted to the headend for centralized analysis, thereby maintaining diagnosis accuracy while dramatically improving labor efficiency
Solution Approach 2:
The patent introduces communication devices as intermediaries between the communication system and service personnel. These devices perform local spectrum analysis and transmit the captured information through existing communication channels to the headend, serving as a mediator that bridges the gap between remote locations and central diagnostic capabilities without requiring physical presence of technicians at each site
2Measurement precision
If service personnel analyze one location at a time, then measurement accuracy is maintained, but time consumption increases
Solution Approach 1:
The patent implements preliminary spectrum analysis at each location by equipping communication devices with spectrum analysis capability. The devices continuously or periodically capture spectrum information in advance, storing it locally or transmitting it to the headend before service personnel arrive. This preliminary capture of diagnostic data eliminates the need for time-consuming on-site analysis while preserving measurement accuracy through automated data collection
3Measurement precision
If traditional spectrum analyzers are used, then measurement capability is sufficient, but device complexity and cost increase
Solution Approach 1:
The patent makes communication devices (cable modems, set-top boxes) multi-functional by integrating spectrum analysis capability into existing equipment. Instead of using dedicated spectrum analyzers, the system leverages the processing power and communication capabilities of devices already present in the network, allowing these devices to perform both their primary communication functions and diagnostic spectrum analysis, thereby reducing overall system complexity and cost
Solution Approach 2:
The patent enables communication devices to perform self-diagnosis by capturing their own spectrum analysis information and transmitting it to the headend. The devices serve themselves diagnostically without requiring external measurement equipment or technician intervention, automatically monitoring their operational environment and reporting anomalies, which simplifies the overall system architecture
4Reliability
If reactive maintenance is performed after problems occur, then response to failures is adequate, but system performance degradation continues
Solution Approach 1:
The patent implements continuous feedback loops where communication devices transmit spectrum analysis information to the headend, which processes the data to identify operational trends, potential failures, or degradations. This feedback mechanism enables the system to monitor its own health status continuously and trigger alerts or automated responses before actual failures occur, transitioning from reactive to proactive maintenance and reducing the duration of performance degradation

AI summary
Spectrum analysis (SA) capability is included in various communication devices within a communication network. One or more of the devices use the SA information from other devices in the system to determine status of various communication links were devices in the system. One or more processors within one or more devices can identify any actual/existing or expected failure or degradation of the various components within the system. Such components may include communication devices, communication channels or links, interfaces, interconnections, etc. When an actual/existing or expected failure or degradation is identified, the affected components may be serviced or devices within the system may operate to mitigate any reduction in performance caused by such problems. Such SA functionality/capability may be implemented in one communication device or in a distributed manner across a number of devices in a communication system.
