Automatic STB Placement via Airtime Utilization Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining the optimum placement of Wi-Fi connected set top boxes in a home environment to ensure sufficient Wi-Fi capacity for simultaneous video streaming is challenging due to the lack of a reliable method, leading to time-consuming and inefficient trial-and-error processes.
Innovation Solution
An automatic placement process using airtime utilization calculations, where an intelligent network controller calculates the total airtime needed for set top boxes and compares it to the available channel capacity, providing recommendations for reconfiguration to prevent overload, such as moving the gateway or adding satellites to improve End-to-End PHY rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trial and error method is used to determine STB placement, then installation can be completed, but the process is time-consuming and lacks reliability
Solution Approach 1:
The system performs preliminary calculations of airtime utilization and channel capacity requirements before finalizing STB placement. The network controller pre-computes whether the Wi-Fi channel can support the proposed number of STBs, allowing installers to plan placement without trial-and-error testing during installation.
Solution Approach 2:
The system provides automated feedback to the installer regarding whether the proposed STB placement will overload the Wi-Fi channel. The network controller analyzes airtime utilization data and communicates back whether the current or proposed configuration is viable, enabling data-driven placement decisions.
2Adaptability or versatility
If multiple STBs are installed to support simultaneous streaming, then video service capacity increases, but Wi-Fi channel overload risk increases
Solution Approach 1:
The system takes preliminary anti-action by preventing STB placements that would cause channel overload before deployment occurs. The network controller calculates airtime requirements and compares them against available channel capacity, rejecting configurations that would lead to instability rather than allowing overload conditions to develop.
Solution Approach 2:
The system changes the parameter of STB placement configuration based on calculated airtime utilization. When the analysis shows that proposed placements would exceed channel capacity, the system modifies the recommended configuration to maintain stability while still supporting adequate video streaming capacity.
3Manufacturing precision
If STB placement is determined without automated analysis, then installation process is simple, but placement accuracy and performance optimization are poor
Solution Approach 1:
The network controller performs self-service by automatically analyzing airtime utilization and generating placement recommendations without requiring complex manual calculations by the installer. The system uses its own network data to assess capacity requirements and provide optimized placement guidance.
Solution Approach 2:
The network controller acts as an intermediary between the installer and the STB placement decision. Rather than requiring the installer to manually calculate capacity requirements or guess optimal placements, the controller mediates by providing data-driven recommendations based on automated airtime analysis.

AI summary
Embodiments include an automatic set top box placement (STB) process and system that balances video playback needs against the performance characteristics of individual devices and the communications system. For video playback, this involves maintaining required sustained data rates needed to support video of various levels of quality and resolution and matching these against the capacity of the Wi-Fi system in terms of channel capacity and gateway/Access Point to STB connection quality. An intelligent network controller calculates the STB total airtime. Each STB is associated with a Service Set Identifier (SSID) that the controller uses to identify the STB clients. The controller calculates the End-to-End PHY rates for each client. The total STB airtime can then be calculated and compared to the default allocation for the STBs. Recommendations regarding moving STBs, gateways, and or satellite/booster devices can then be provided to the user.
