Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reception of a wireless communication terminal is significantly affected by its position relative to a base station, leading to inconsistent communication quality within a specific space, such as an airplane cabin, where electromagnetic waves are blocked.
Innovation Solution
A wireless communication system comprising a wireless communication terminal and a wireless access device that exchange location and position information, including tilt and direction, to calculate and provide recommended positions for optimal communication, ensuring a stable connection by adjusting the terminal's orientation for better signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication terminal uses fixed antenna selection based on tilt, then the device complexity is reduced, but the communication quality becomes insufficient in dynamic environments
Solution Approach 1:
The patent implements dynamic antenna selection by continuously monitoring terminal tilt angles and direction information, then automatically switching between multiple antennas based on real-time position data. This dynamic adaptation allows the system to maintain optimal communication quality as the terminal moves through the airplane cabin, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The system establishes a feedback loop where the terminal reports its tilt and direction information to the access point, which then adjusts antenna selection accordingly. This closed-loop feedback mechanism enables continuous optimization of communication quality without requiring complex manual intervention, balancing reliability improvement with acceptable system complexity.
2Reliability
If the wireless communication terminal provides detailed location and position information to the access point, then the communication quality improves, but the information transmission overhead increases
Solution Approach 1:
The patent applies local quality by selecting and processing only the most relevant position parameters (tilt angle and direction) rather than transmitting complete location data. This selective information approach maintains connection stability while minimizing information overhead, as the system focuses on the specific orientation data needed for antenna selection rather than comprehensive location tracking.

AI summary
The wireless access device is installed in a predetermined space so as to be connected to a wireless communication terminal. The wireless access device comprises a radio communication component, a controller and a memory. The radio communication component receives terminal location information, terminal position information, and communication situation information from the wireless communication terminal. The memory holds the terminal location information, the terminal position information, and the communication situation information such that they are associated with each other. The controller calculates a recommended tilt, and a recommended direction for the wireless communication terminal based on the terminal position information and the communication situation information. The radio communication component transmits the calculated information to the wireless communication terminal corresponding to the terminal location information.
