Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless communication methods in industrial settings, such as factories, are unreliable due to potential errors that can disrupt manufacturing processes, and existing solutions require association exchanges between client devices and access points, which can slow down roaming and prevent multi-point to multi-point radio connectivity.
Innovation Solution
The implementation of an associationless wireless communication system using an overhead mesh of access points, where client devices register with a controller and transmit messages as beam cones directed upward, allowing relaying without prior association, and utilizing scheduled communication and different wireless channels to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wireless communication methods are used in industrial settings, then devices can communicate wirelessly, but errors in communication can disrupt manufacturing processes
Solution Approach 1:
The patent introduces access points as intermediary devices that relay communications between mobile devices and the network infrastructure. Instead of direct peer-to-peer wireless communication, all communications pass through controlled access points that can validate, authenticate, and ensure reliable transmission, thereby maintaining wireless convenience while improving communication reliability through the mediator layer
Solution Approach 2:
The system implements feedback mechanisms where access points monitor communication quality, device locations, and network conditions. Based on this feedback, the system dynamically adjusts communication parameters, manages associations, and ensures reliable data transmission in industrial environments, resolving the contradiction between wireless operation and communication reliability
2Reliability
If association exchanges are performed between client devices and access points, then wireless communication can be established, but roaming speed is slowed down
Solution Approach 1:
The patent implements preliminary actions by pre-establishing associations between mobile devices and multiple access points before roaming is needed. Devices maintain pre-configured associations with several access points in advance, so when moving between coverage areas, they can seamlessly switch to a pre-associated access point without performing time-consuming association exchanges, thus maintaining connection stability while improving roaming speed
Solution Approach 2:
The system dynamically manages associations based on real-time device location and network conditions. Instead of static one-to-one associations, the system allows devices to maintain multiple dynamic associations that are automatically updated as devices move, enabling fast roaming while maintaining reliable connections through adaptive association management
3Reliability
If association exchanges are required for wireless communication, then secure connections can be established, but multi-point to multi-point radio connectivity is prevented
Solution Approach 1:
The patent implements universal association management where a single association framework supports multiple communication modes simultaneously. The access point association mechanism works for both traditional one-to-peer communications and multi-point-to-multi-point radio connectivity scenarios, providing a unified secure connection method that adapts to different communication patterns without requiring separate association protocols, thus maintaining security while enabling versatile multi-point connectivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances reliability and efficiency by eliminating the need for association exchanges, ensuring continuous connectivity during roaming, and preventing interference, while maintaining redundancy and reliability through scheduled communication and channel management.
Implementation Method 1
The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points
Data Source
AI summary
In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.
