Wireless Docking Station Distance Bandwidth Admission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless docking systems face privacy issues due to automatic connection outside the user's working area, as the admission range can be larger than the physical workspace, potentially allowing unauthorized access to private information, and reducing the minimum bandwidth for admission decreases system coverage in locations with obstacles.
Innovation Solution
A wireless docking station that uses a combination of bandwidth and distance measurements, filtered to account for typical user velocity, to determine the effective work area, ensuring connections are only established within the user's workspace, thereby maintaining privacy and system coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the admission range is increased to allow automatic connection, then the user experience is improved, but privacy security deteriorates as users may connect outside their working area
Solution Approach 1:
The patent changes the parameter of connection admission from solely bandwidth-based to a composite parameter incorporating both bandwidth and distance measurements. This allows the system to maintain automatic connection functionality while restricting it to appropriate spatial boundaries, resolving the contradiction between ease of operation and privacy security.
Solution Approach 2:
The patent introduces distance measurement as an intermediary parameter that mediates between the user's desire for automatic connection and the need for privacy protection. By measuring the physical distance between the mobile device and docking station, the system can determine whether automatic connection should be permitted, acting as a mediator that enables convenient connection only when spatially appropriate.
2Object-affected harmful factors
If the minimum bandwidth level is increased to reduce admission range, then privacy security is improved, but system coverage deteriorates in locations with obstacles
Solution Approach 1:
The patent changes the admission criterion from a single bandwidth parameter to a composite of bandwidth and distance parameters. This allows the system to maintain broader coverage by admitting connections based on spatial proximity even when bandwidth is marginal, while still protecting privacy through the distance constraint. The distance parameter compensates for bandwidth variations caused by obstacles.
Solution Approach 2:
The patent applies different admission criteria based on local spatial conditions. By measuring distance and comparing it to a threshold, the system creates a spatially-aware admission policy that adapts to the physical layout of the workspace. This allows the system to maintain coverage in obstacle-prone areas while ensuring connections only occur within the appropriate work area.
3Device complexity
If bandwidth measurements are used alone for admission control, then the admission process is simple, but the system cannot distinguish between close and far connections
Solution Approach 1:
The patent adds a distance measurement parameter to the admission control process, transforming it from a simple bandwidth check to a composite evaluation. While this increases complexity slightly, it dramatically improves location detection precision by providing spatial context that bandwidth alone cannot provide, enabling the system to distinguish between nearby and distant devices.

AI summary
A docking station and a method for establishing a wireless connection to a device in which the docking station is configured to use the distance between the device and the docking station in the admission and retention control decision. This effectively prevents the wireless docking session from initiating, or drops an existing session, when the user is determined to be outside of the effective work area as determined by the docking station.
