Radio Repeater Relay Equalizer Remote Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In half-duplex communication systems, adjusting sound quality for radio devices is time-consuming and costly due to the need for on-site engineer intervention and repeated configuration changes across multiple terminals, especially since the desired frequency characteristic varies by user language, making existing techniques impractical.
Innovation Solution
A radio repeater system with a relay equalizer that adjusts frequency characteristics based on configuration information received from a management apparatus, allowing remote sound quality adjustments without requiring on-site engineer visits, by transmitting configuration updates directly to the repeater and terminals via a communication line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If configuration changes are made to multiple terminals to adjust sound quality, then the desired frequency characteristic can be achieved, but the adjustment time increases significantly
Solution Approach 1:
A management server is introduced as an intermediary between the repeater and multiple terminals. The server receives language information, determines appropriate equalizer parameters, and automatically distributes configuration updates to relevant terminals. This intermediary automates the coordination process, eliminating the need for manual repeated adjustments across terminals and significantly reducing adjustment time while maintaining sound quality precision.
2Manufacturing precision
If on-site engineer visits are conducted to determine optimal correction values, then appropriate sound quality correction can be achieved, but the adjustment cost increases
Solution Approach 1:
The system enables self-service operation where the management server automatically determines optimal equalizer parameters based on language information received from terminals or users. The server autonomously configures the repeater and distributes settings to terminals without requiring on-site engineer intervention. This automation maintains correction accuracy while eliminating travel and manual adjustment costs.
Solution Approach 2:
The system changes the approach from manual parameter adjustment to automated parameter determination. The management server receives language information (a key parameter) and automatically selects appropriate equalizer parameters based on pre-stored data or algorithms. This parameter-driven automation replaces costly on-site engineering services while maintaining optimal correction values.
3Manufacturing precision
If configuration updates are distributed to multiple terminals, then sound quality can be adjusted across the system, but the operational complexity increases
Solution Approach 1:
The management server acts as a centralized intermediary that simplifies configuration management. Instead of manually coordinating updates across multiple terminals, the server automatically receives language information, determines appropriate parameters, and distributes configurations to all necessary terminals in one operation. This centralization reduces operational complexity while achieving system-wide frequency characteristic adjustment.
Solution Approach 2:
The management server provides universal configuration management functionality that serves multiple terminals simultaneously. A single configuration update operation from the server can apply to the repeater and multiple terminals based on language groupings. This multi-functional approach simplifies the overall system operation by consolidating what would otherwise be multiple separate adjustment tasks into one unified process.

AI summary
The present disclosure is aimed at making an adjustment operation for sound quality evaluation of a radio device easy. A radio repeater includes: a reception unit configured to receive a radio signal from a first radio terminal; a relay equalizer configured to adjust a frequency characteristic of the radio signal based on a configuration; a configuration reflection unit configured to reflect configuration information on the frequency characteristic received via a communication line in a configuration of the relay equalizer; and a transmission unit configured to transmit the radio signal that has been adjusted to a second radio terminal.
