Solution Overview
Problem
Conventional In-Flight Entertainment (IFE) systems face challenges in maintaining optimal wireless communication conditions for passengers due to varying distances from wireless access points, leading to inconsistent data transmission quality and stability.
Innovation Solution
A wireless terminal and communication system that includes a seat position identifying unit, distance determination unit, and processing setting unit, which identifies the user's seat position, determines the distance to wireless access points, and adjusts communication settings such as data rate and initial gain control to optimize communication based on distance, ensuring stable and appropriate data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless access points are placed at fixed locations in the facility, then the device complexity is reduced, but the communication reliability deteriorates due to varying distances from seats
Solution Approach 1:
The patent implements dynamic communication parameter adjustment based on real-time distance measurements. The terminal device continuously monitors its distance from the wireless access point and dynamically adjusts communication parameters (such as transmission power, data rate, or modulation scheme) to maintain optimal communication reliability despite varying distances from fixed access points.
Solution Approach 2:
The system changes communication parameters according to the determined distance between the terminal and access point. When the distance exceeds a threshold, the terminal adjusts parameters such as increasing transmission power or switching to more robust modulation schemes to compensate for signal attenuation and maintain communication reliability.
2Reliability
If communication parameters are adjusted for each seat position, then the communication quality is improved, but the processing complexity increases
Solution Approach 1:
The patent applies local quality adjustment by tailoring communication parameters to specific local conditions (distance from access point). Instead of using uniform parameters across all seats, the system determines the terminal's position and adjusts parameters locally based on the measured distance, ensuring optimal communication quality for each specific location while avoiding excessive processing complexity through rule-based adjustment logic.
3Stability of the object's composition
If the terminal determines distance and adjusts processing, then the communication stability is improved, but the terminal complexity increases
Solution Approach 1:
The terminal device performs self-service by autonomously determining its own position relative to the access point and automatically adjusting its communication parameters without requiring external control. The terminal uses its own sensors or signal strength measurements to determine distance and independently modifies its transmission parameters to maintain stable communication, reducing the need for complex external control systems.

AI summary
A wireless terminal communicates with a wireless communication apparatus including one or more wireless access points, and is used in a facility including a plurality of seats. The wireless terminal includes a seat position identifying unit, a distance determination unit, and a processing setting unit. The seat position identifying unit identifies a seat position of a user of the wireless terminal. The distance determination unit determines a distance from the identified position to the one or more wireless access points. The processing setting unit sets the processing associated with communication based on the determined distance.
