Visible Light Communication Terminal Multi-Base Station Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visible light communication systems face challenges in achieving multi-base station communication due to the high directivity of visible light, which limits the ability to perform simultaneous communication with multiple base stations.
Innovation Solution
A visible light communication system is designed with a terminal apparatus equipped with multiple visible light communicators, each having a different directivity, and a controller that performs simultaneous communication control, allowing the terminal apparatus to communicate with multiple base stations simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visible light communication uses high directivity for stable communication, then communication reliability is improved, but the ability to perform simultaneous communication with multiple base stations deteriorates
Solution Approach 1:
The terminal apparatus is divided into multiple visible light communicators (first visible light communicator, second visible light communicator, etc.), each capable of independent communication with different base stations. This segmentation allows simultaneous multi-base station communication while maintaining the high directivity and reliability of individual communicators.
2Device complexity
If a terminal apparatus uses a single visible light communicator, then device complexity is reduced, but the capability to perform simultaneous communication with multiple base stations is lost
Solution Approach 1:
The terminal apparatus employs multiple visible light communicators instead of a single communicator, enabling parallel communication channels with multiple base stations. This increases communication efficiency and productivity while the controller manages the complexity through centralized coordination.
Solution Approach 2:
The controller dynamically assigns and switches between different visible light communicators based on communication requirements, base station positions, and signal conditions. This dynamic management optimizes the use of multiple communicators and adapts to changing communication scenarios.
3Stability of the object's composition
If visible light communicators are fixed in position, then communication stability is improved, but adaptability to moving target base stations deteriorates
Solution Approach 1:
The system transitions from fixed to dynamic operation by enabling the terminal apparatus to move and track base stations. The controller continuously monitors communication conditions and switches between visible light communicators to maintain stable connections despite terminal movement or base station relocation.
Solution Approach 2:
Multiple visible light communicators are positioned at different orientations within the terminal apparatus, providing coverage in different directions. This segmentation of communication functions allows the terminal to track and communicate with base stations across various positions while maintaining stability through appropriate communicator selection.

AI summary
A terminal apparatus includes multiple visible light communicators including a visible light communicator and a visible light communicator, and a controller configured to control the multiple visible light communicators. The multiple visible light communicators each have a directivity in a different direction. The controller is configured to perform simultaneous communication control of the visible light communicators, the visible light communicator performing visible light communication with a base station apparatus and the visible light communicator performing visible light communication with a base station apparatus.
