Pole Proximity Channel Switching for Mobile Node Key-Hole Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The key-hole phenomenon in wireless communication networks, where mobile nodes experience a decrease in received signal strength and throughput when approaching and exiting a base station, is not effectively addressed by existing pole banning methods, which are often difficult to configure and do not provide optimal alternative communication mechanisms.
Innovation Solution
Implementing Multi-Link Operations (MLO) using Wi-Fi 7's multi-radio capabilities to opportunistically enable secondary wireless communication channels, such as mmWave or Li-Fi, when a mobile node approaches an area of reduced coverage, and switching back to the primary channel upon exiting, to maintain connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pole banning is implemented based on RSSI threshold, then mobile node connectivity is maintained, but configuration difficulty increases and performance is non-optimal
Solution Approach 1:
The patent changes the parameter basis from RSSI threshold to predicted path geometry. By calculating the mobile node's predicted path and identifying key-hole areas geometrically, the system determines pole ban conditions without requiring RSSI threshold configuration, thereby reducing configuration difficulty while maintaining connectivity reliability
Solution Approach 2:
The system enables self-service by automatically calculating the mobile node's predicted path and identifying key-hole areas without manual configuration. The mobile node's own movement data and the base station's location information are used to automatically determine when pole banning should be applied, eliminating the need for operator configuration of RSSI thresholds
2Reliability
If pole banning is implemented based on RSSI threshold, then mobile node connectivity is maintained, but communication performance becomes non-optimal
Solution Approach 1:
The patent applies preliminary action by calculating the mobile node's predicted path and identifying key-hole areas before the mobile node actually enters them. By predicting the path in advance and pre-determining pole ban conditions based on geometric analysis, the system can proactively manage connectivity without waiting for RSSI degradation, thereby maintaining optimal communication performance
Solution Approach 2:
The patent replaces the mechanical RSSI threshold-based system with a geometric prediction system. Instead of relying on signal strength measurements that degrade performance, the system uses predicted path geometry and key-hole area identification to determine pole ban conditions, achieving both reliable connectivity and optimal communication performance
3Reliability
If secondary wireless communication channels are enabled, then signal strength and throughput are enhanced, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the wireless communication channel configuration adaptive rather than static. The system dynamically enables secondary channels (mmWave, Li-Fi) only when the mobile node is predicted to enter key-hole areas, and switches back to primary channels when exiting these areas. This dynamic adaptation enhances signal strength and throughput precisely when needed without continuously increasing device complexity
Solution Approach 2:
The patent applies local quality by providing different communication channel configurations for different spatial locations. Secondary channels are enabled specifically in key-hole areas where primary channels degrade, while primary channels are used elsewhere. This localized optimization enhances performance in problematic areas without unnecessarily complicating the device configuration in areas where primary channels suffice

AI summary
In one embodiment, a method described herein includes identifying, by a device, an area of reduced wireless communication coverage for a primary wireless communication channel utilized for wireless communication by a mobile node during transit of the mobile node along a predicted path and enabling, by the device and in preparation of the mobile node entering the area, a secondary wireless communication channel configured to provide a threshold level of wireless communication coverage for wireless communication by the mobile node during transit through the area along the predicted path. The method further includes returning, by the device and based on the mobile node exiting the area, to the primary wireless communication channel to provide wireless communication by the mobile node.
