Solution Overview
Problem
Conventional wireless fixed-line phone routers have limited coverage due to the small number of mobile phone base stations in a given area, leading to potential communication disruptions when the user is outside the cell coverage of existing base stations.
Innovation Solution
A wireless fixed-line phone router equipped with both LTE Cat. 1 and LTE Cat. M1 communication standards, allowing it to switch to LTE Cat. M1 for wider coverage when communication quality deteriorates, ensuring continuous connectivity by utilizing the coverage enhancement function of LTE Cat. M1.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LTE Cat. 1 communication standard is used, then power consumption is reduced and cost is lowered, but communication coverage is limited and communication quality deteriorates in areas with poor signal
Solution Approach 1:
The wireless fixed-line phone router is equipped with both LTE Cat. 1 and LTE Cat. M1 communication modules, enabling it to perform multiple communication functions. The system can selectively use LTE Cat. 1 for normal operation and LTE Cat. M1 for coverage enhancement, achieving multi-functionality that adapts to different communication scenarios and improves overall reliability across diverse environments.
Solution Approach 2:
The system dynamically changes communication parameters by switching between LTE Cat. 1 and LTE Cat. M1 standards based on signal quality conditions. When the LTE Cat. 1 signal quality falls below a threshold, the system transitions to LTE Cat. M1 which operates with different technical parameters optimized for poor coverage areas, thereby maintaining communication quality through parameter adaptation.
2Adaptability or versatility
If LTE Cat. M1 communication standard is used, then coverage range is extended, but power consumption increases and cost increases
Solution Approach 1:
The communication system operates dynamically by automatically switching between LTE Cat. 1 and LTE Cat. M1 standards based on real-time signal quality assessment. The router monitors communication conditions and activates LTE Cat. M1 only when necessary (when LTE Cat. 1 quality deteriorates), thereby extending coverage range dynamically while minimizing power consumption by avoiding continuous use of the higher-power LTE Cat. M1 mode.
Solution Approach 2:
The patent extracts the coverage enhancement function into a separate LTE Cat. M1 communication module that operates independently from the primary LTE Cat. 1 module. This allows the system to use LTE Cat. M1's wider coverage capability only when extracted/activated based on specific conditions, rather than continuously operating at higher power consumption levels.
3Reliability
If dual communication modules are equipped, then communication reliability is improved through standard switching, but device complexity increases
Solution Approach 1:
The patent merges the control functions for both LTE Cat. 1 and LTE Cat. M1 modules into a unified control mechanism within the control unit. The control unit integrates signal quality monitoring, threshold comparison, and switching decision-making for both communication standards, thereby managing the complexity of dual modules through functional consolidation rather than separate independent control systems.
Solution Approach 2:
The control unit acts as an intermediary that manages the interaction between the LTE Cat. 1 and LTE Cat. M1 communication modules. It monitors communication quality, determines when switching is necessary, and executes the transition between standards, thereby simplifying the overall system architecture by providing a centralized mediation layer that coordinates the dual modules without requiring complex point-to-point control circuits between them.

AI summary
A wireless fixed-line phone router to which at least a wireless fixed-line phone is connected includes a first communication unit that performs communication according to a first mobile communication standard, a second communication unit that performs communication according to a second mobile communication standard that is a mobile communication standard different from the first mobile communication standard and is capable of performing communication in a wider range than the first mobile communication standard, and a control unit that causes the second communication unit to perform communication in a case where communication quality deteriorates when the first communication unit performs communication.
