Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data transmission rates are reduced due to limited bandwidth when multiple SIM cards in a network node connect to the same base station through the same frequency band.
Innovation Solution
The network node employs a plurality of WCMs with rotatable and tiltable antenna elements, allowing for selective disconnection and reconnection to different base stations based on current geographical area and antenna orientation, utilizing a database for storing antenna characteristics and geographical information to optimize connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple WCMs connect to the same base station through the same frequency band, then the network node can establish multiple connections for redundancy, but the data transmission rate is reduced due to limited bandwidth
Solution Approach 1:
The patent segments the WCMs into different groups based on their antenna characteristics and geographical coverage areas. Each WCM is assigned to connect to base stations in specific directional sectors, preventing multiple WCMs from competing for the same frequency band resources at the same base station. This segmentation maintains connection redundancy while eliminating bandwidth conflicts.
Solution Approach 2:
The patent introduces spatial dimensionality by utilizing rotatable and tiltable antenna elements that can orient in different directions. By adding this spatial dimension to the connection architecture, the system can simultaneously maintain multiple connections to different base stations in different directions, thereby achieving both redundancy and high data transmission rates without frequency band conflicts.
2Device complexity
If multiple WCMs use the same frequency band, then device complexity is reduced, but interference increases and bandwidth utilization is limited
Solution Approach 1:
The patent implements dynamic antenna orientation control where the rotatable and tiltable antenna elements can adjust their directions in real-time based on the current geographical area and available base stations. This dynamic adjustment allows the system to adapt to changing network conditions, optimize signal quality, and avoid interference by orienting antennas toward base stations using different frequency bands.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the current geographical area, base station availability, and connection quality. Based on this feedback, the network node automatically adjusts antenna orientations and selects appropriate base stations, ensuring optimal frequency band utilization and minimizing interference among WCMs while maintaining simple device architecture.

AI summary
Methods and systems for improving connectivity between a network node and a base station during data communication over a cellular network are described. The network node comprises a first plurality of WCMs. The method includes identifying, by the network node, a first base station connected to a second plurality of WCMs. The second plurality of WCMs include all or part of the first plurality of WCMs. After that, a WCM is selected from the second plurality of WCMs to maintain a connection with the first base station. The rest of the second plurality of WCMs are disconnected from the first base station. The disconnected WCMs are reconnected in a manner so that each of the second plurality of WCMs becomes connected to a different base station or to the same base station over different frequency bands.
