Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face issues with limited service coverage and degraded network quality due to obstacles, leading to increased handover chances and communication latency when user equipment moves out of wireless access point range.
Innovation Solution
A wireless communication device with mobility that measures wireless signal status, divides zones into sub-blocks based on signal strength, and selects a preferred sub-block for communication using user context information to reduce handover and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless access points are deployed in space to extend service coverage, then communication dead zones are avoided, but handover chances increase and communication latency increases
Solution Approach 1:
The wireless communication device is designed to be movable rather than fixed, allowing it to dynamically adjust its position to optimize signal reception. The device can move between different locations to find the best communication path, eliminating the need for multiple fixed access points and reducing handover latency.
Solution Approach 2:
The service zone is divided into multiple sub-blocks based on signal strength and communication quality. The movable device selects optimal sub-blocks for communication, allowing flexible coverage without requiring physical deployment of multiple access points throughout the entire zone.
2Reliability
If wireless access points are deployed to extend service coverage, then communication dead zones are avoided, but the complexity of the system increases
Solution Approach 1:
The movable wireless communication device autonomously measures signal strength, determines optimal positions, and selects communication paths without requiring manual configuration or control of multiple fixed access points. This self-service capability simplifies system management while maintaining reliable coverage.
Solution Approach 2:
A single movable device performs multiple functions that would otherwise require multiple fixed access points: it provides signal measurement, position optimization, and communication relay. This multi-functionality reduces the overall number of components needed in the system.
3Ease of manufacture
If fixed wireless access points are used, then deployment is simple, but service coverage is limited and handover occurs frequently
Solution Approach 1:
The system transitions from static fixed access points to a dynamic movable device that can traverse the service zone. This dynamic approach allows a single device to cover a larger area by moving to optimal positions, expanding coverage without requiring multiple deployed access points.
Solution Approach 2:
The solution adds the temporal dimension to coverage expansion. Instead of expanding spatial coverage by deploying more physical access points, the system achieves expanded coverage by moving the single access point through time and space, visiting multiple locations sequentially.

AI summary
A wireless communication device and a moving method thereof are provided. The moving method is adapted for the wireless communication device moving in a zone. While moving in the zone, a wireless signal status of a signal source device is measured. The zone is divided into multiple sub-blocks, and a spatial weight parameter corresponding to each of the sub-blocks is determined according to the wireless signal state of the signal source device. In response to a user equipment being connected to the wireless communication device, a preferred sub-block is selected from the sub-blocks according to user context information of the user equipment and the spatial weight parameter corresponding to each of the sub-blocks. The wireless communication device moves into the preferred sub-block to perform wireless communication with the signal source device and the user equipment within the preferred sub-block.
