Dynamic Route Selection for EHF Wireless Communication Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In EHF wireless communication systems, the high directivity and short communication range lead to complex routing control calculations and difficulties in selecting appropriate hop destinations due to antenna directivity, resulting in inflexible network configurations and increased communication costs.
Innovation Solution
A communication system that dynamically establishes alternative communication routes using multiple communication apparatuses, which include a CPU, memory, and an antenna unit, to transfer content data even when direct communication is disrupted, by detecting disconnections and transferring control data to reroute the communication path.

Engineering Contradiction Analysis
1Productivity
If EHF wireless communication is used to achieve high-speed and large-capacity communication, then communication speed and capacity are improved, but communication range becomes short and directivity becomes high
Solution Approach 1:
The patent segments the communication path into multiple hops through intermediate devices. Instead of requiring direct long-range communication, the system divides the transmission into shorter segments that can be relayed through multiple devices, thereby extending the overall communication range while maintaining the benefits of EHF wireless communication.
Solution Approach 2:
The patent introduces intermediary communication devices that act as relays between the source and destination. These intermediate devices receive, process, and forward data packets, enabling extended communication range by bridging the gap created by the limited direct communication range of EHF waves.
2Length of stationary object
If autonomous distributed mesh network is constructed to extend communication distance, then communication range is extended, but routing control calculation becomes complicated and network configuration becomes inflexible
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and storing multiple alternative routes before communication disruptions occur. When a disconnection is detected, the system can immediately switch to a pre-prepared alternative route without performing complex real-time calculations, thereby reducing routing control complexity while maintaining extended communication range.
Solution Approach 2:
The patent implements dynamic route selection that adapts to changing network conditions. The system can flexibly switch between different communication paths based on real-time connection status, making the network configuration flexible while managing routing complexity through intelligent dynamic adjustment rather than static complex calculations.
3Productivity
If antenna directivity is increased to improve communication efficiency, then communication efficiency is improved, but selection of appropriate hop destination becomes difficult
Solution Approach 1:
The patent implements feedback mechanisms where communication devices report their status, location, and connection quality to the network. This feedback enables the system to intelligently select appropriate hop destinations by considering antenna directivity constraints, thereby maintaining communication efficiency while simplifying destination selection through information-driven decision-making.
Solution Approach 2:
The patent enables communication devices to autonomously determine their suitability as hop destinations by evaluating their own antenna orientation, connection status, and network position. This self-service capability allows devices to automatically participate in route selection without requiring complex centralized control, thus maintaining communication efficiency while easing destination selection.

AI summary
A communication system includes a first communication apparatus, a second communication apparatus, and a third communication apparatus. The first communication apparatus transfers content data to the second communication apparatus and the third communication apparatus using wireless communication. The second communication apparatus includes a first communication unit that transfers first control data including a reception request for receiving the content data transferred by the first communication apparatus if the wireless communication between the second communication apparatus and the first communication apparatus is disconnected. The third communication apparatus includes a second communication unit that transfers the content data transferred by the first communication apparatus to the second communication apparatus using the wireless communication if the third communication apparatus receives the first control data from the second communication apparatus.
