Access Point Object Tracking for Wireless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless Access Point (AP) systems face challenges in efficiently managing handovers between multiple APs, leading to temporary bandwidth reduction and increased processing resources, especially when entities move within environments with multiple APs, as they struggle to balance load and maintain connectivity while tracking objects in real-time.
Innovation Solution
A system comprising multiple APs with camera sensors, range finder sensors, and radios that create profiles for entities by determining their location and providing wireless communication, allowing for proactive handover and load balancing by identifying entities through image processing and range finding, enabling real-time object tracking and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple APs perform handover services for moving entities, then connectivity is preserved, but processing resources increase and bandwidth temporarily decreases
Solution Approach 1:
The system performs preliminary tracking of entities using camera sensors and range finders to predict their movement trajectories. This allows the network to proactively prepare handover procedures before the entity actually moves between AP coverage areas, reducing the processing burden during actual handover and maintaining bandwidth efficiency.
Solution Approach 2:
The system continuously monitors entity positions, movement patterns, and network conditions, using this feedback to dynamically adjust handover timing and resource allocation. This feedback mechanism optimizes the balance between maintaining connectivity and preserving processing resources and bandwidth.
2Measurement precision
If APs track objects in real-time using sensors, then object location is determined accurately, but device complexity increases
Solution Approach 1:
The Access Points are designed to perform multiple functions: traditional wireless networking, camera-based entity identification, range finding, and real-time tracking. By making the APs multi-functional, the system achieves accurate object location determination without adding separate dedicated tracking infrastructure, thereby limiting the increase in device complexity.
3Productivity
If proactive handover is implemented using entity tracking, then bandwidth is maintained, but processing resources increase
Solution Approach 1:
The system implements selective tracking and handover preparation only for entities that are moving between AP coverage areas, rather than continuously processing all entities. By applying tracking and handover preparation only when necessary (partial action), the system maintains bandwidth for moving entities while avoiding unnecessary processing resource consumption.

AI summary
The present disclosure provides improved determinism in systems and methods for wireless communications via real-time visual object tracking using radio, video, and range finding. In one example, a first and a second Access Point (AP) in a constellation in which the APs are positioned at knowns position in the environment, and the APs perform image processing to identify an entity the environment based on captured images and an entity definition. The APs receive, via range finders, ranges between the entity and the first and second APs to determine a location of the entity in the environment. The APs may then create a profile for the entity that includes an entity identifier, the location of the entity, and indicates whether one of the first AP and the second AP is in wireless communication with the entity.
