Wireless Access Device Positioning for Link Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems struggle to maintain communication quality for mobile terminals as they move away from fixed wireless access devices, leading to deteriorated link quality and unsatisfied communication requirements.
Innovation Solution
A wireless access device that detects the quality of its link with a mobile terminal and moves to optimize the connection by determining the direction of the mobile terminal relative to itself, using parameters like RSSI, access rate, and antenna beam angles, and adjusts its position to improve the link quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless access device is fixed at a specific location, then the device structure is simple and easy to deploy, but the communication quality deteriorates when the mobile terminal moves away
Solution Approach 1:
The patent makes the wireless access device movable instead of fixed, allowing it to dynamically adjust its position to maintain optimal communication quality with mobile terminals. The device can move along a determined trajectory to follow or approach the mobile terminal, ensuring reliable connection even when terminals are in motion.
2Reliability
If the wireless access device moves to follow the mobile terminal, then the communication quality is maintained, but the device requires complex movement control and positioning systems
Solution Approach 1:
The patent replaces complex mechanical positioning and movement control systems with electromagnetic field-based detection and calculation. The wireless access device uses signal parameters (RSSI, angle of arrival) to determine the mobile terminal's position and calculates the optimal movement trajectory through mathematical computation rather than complex mechanical control.
Solution Approach 2:
The wireless access device autonomously determines its own movement trajectory based on detected signal parameters without requiring external control systems. It self-adjusts its position by processing RSSI values and angle information to calculate the optimal path toward the mobile terminal independently.
3Reliability
If the wireless access device continuously monitors and adjusts its position, then the communication quality requirement is satisfied, but the energy consumption increases
Solution Approach 1:
The wireless access device performs periodic detection of signal parameters (RSSI, angle of arrival) at specific intervals rather than continuous monitoring. This periodic measurement approach allows the device to track the mobile terminal's position over time while reducing energy consumption compared to continuous real-time monitoring and adjustment.

AI summary
Embodiments of the present invention provide a method and device for wirelessly accessing a service. A wireless access device detects whether quality of a first wireless access link satisfies a communication quality requirement of a single mobile terminal; the wireless access device starts moving from a current location if the wireless access device determines that the quality of the first wireless access link does not satisfy the communication quality requirement of the single mobile terminal; in a moving process, the wireless access device may detect whether a second wireless access link satisfies the communication quality requirement of the single mobile terminal, and stop moving if the second wireless access link satisfies the communication quality requirement or continue moving if the second wireless access link does not satisfy the communication quality requirement. That is, quality of a wireless access link is improved by means of movement of the wireless access device, thereby satisfying the communication quality requirement of the single mobile terminal.
