Integrated Repeater for Multi-Service Signal Relaying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication systems require separate repeaters for each communication service, leading to increased installation costs and aesthetic damage to buildings due to indiscriminate installations, especially in areas with poor signal reception like shadow areas.
Innovation Solution
An integrated repeater and relay system that demultiplexes and converts various communication signals, including mobile communication and Ethernet signals, to relay them effectively through a single system, using demultiplexers, converters, and switching units to ensure seamless signal transmission and fault tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate repeaters are installed for each communication service, then communication service reliability is improved, but installation cost increases and building appearance is damaged
Solution Approach 1:
The patent combines multiple separate repeaters for different communication services (mobile communication, Ethernet, wireless LAN) into a single integrated repeater unit. This integration maintains the reliability of each communication service while reducing the number of installation points, thereby lowering installation complexity and preserving building appearance.
Solution Approach 2:
The integrated repeater is designed to perform multiple functions simultaneously - it can relay mobile communication signals, Ethernet signals, and wireless LAN signals through a single device. This multi-functionality allows one repeater to replace several separate repeaters, achieving the same reliability benefits without the associated installation complexity.
2Reliability
If multiple repeaters are installed in shadow areas, then signal coverage is improved, but installation cost and aesthetic damage increase
Solution Approach 1:
By merging multiple repeater functions into a single integrated unit, the patent reduces the number of visible installation points on building surfaces. This maintains comprehensive signal coverage for multiple communication services while minimizing aesthetic damage from indiscriminate repeater installations.
3Reliability
If separate repeaters are used for each signal type, then signal transmission reliability is improved, but installation and maintenance cost increase
Solution Approach 1:
The integrated repeater incorporates universal signal processing capabilities that can handle mobile communication signals, Ethernet signals, and wireless LAN signals within a single device. This multi-functionality maintains signal transmission reliability for each service type while significantly reducing the overall installation and maintenance costs compared to using separate specialized repeaters.

AI summary
The present invention relates to an integrated repeater and an integrated relay system. The integrated repeater of the present invention receives a signal from a main repeater for relaying signals transmitted from upper devices, and comprises a demultiplexer configured to demultiplex the multiplexed signal of an Ethernet signal and a mobile communication signal received from the main repeater, and separate the signals into the mobile communication signal and the Ethernet signal; a first converter configured to convert the mobile communication signal separated from the demultiplexer into a radio frequency (RF) signal, and transmit the converted RF signal; a second converter configured to convert the Ethernet signal separated from the demultiplexer into a wireless LAN signal, and transmit the converted wireless LAN signal; and a switching unit configured to deliver a signal received from the main repeater to either the demultiplexer or the second converter, depending on whether a fault of the mobile communication signal is generated.
