Solution Overview
Problem
Millimeter-wave communication between terminals is often disrupted when mobile information communication terminals are placed in bags or cases, leading to decreased signal strength and poor communication conditions due to high propagation loss and narrow directivity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If millimeter-wave communication is used for high-speed, large-capacity communication, then communication speed and data capacity are improved, but propagation loss increases and directivity becomes narrow causing communication disruption when terminals are placed in bags or cases
Solution Approach 1:
The patent introduces a repeater as an intermediary device that receives millimeter-wave signals from one terminal and retransmits them to another terminal. This mediator overcomes the propagation loss and narrow directivity issues by providing an intermediate signal amplification and retransmission point, ensuring reliable communication even when terminals are placed in bags or cases with blocked direct paths.
Solution Approach 2:
The communication path is segmented into multiple hops through the repeater rather than relying on a single direct link. This divides the communication journey into manageable segments, allowing the system to maintain high-speed millimeter-wave communication by breaking the long, loss-prone direct path into shorter segments with active signal regeneration at the repeater.
2Quantity of substance
If millimeter-wave communication is used, then large-capacity data transmission is achieved, but signal strength decreases when terminals are positioned in bags or cases
Solution Approach 1:
The repeater acts as a signal strength intermediary that receives weak or blocked millimeter-wave signals and retransmits them with restored amplitude. This allows the system to maintain large-capacity data transmission by compensating for signal strength loss through active retransmission at the repeater, ensuring sufficient energy levels are maintained throughout the communication path.
Solution Approach 2:
The repeater ensures continuous signal presence by continuously receiving and retransmitting millimeter-wave signals. This continuous action maintains signal strength above threshold levels even when terminals are positioned in bags or cases, preventing communication interruptions and ensuring sustained large-capacity data transmission throughout the interaction period.
