Multi-WCM Cellular Connectivity Across Base Stations and Bands
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 wireless communication modules (WCMs) with rotatable and tiltable antenna elements, allowing selective disconnection and reconnection to different base stations based on geographical location 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 connectivity is established, but data transmission rate is reduced due to limited bandwidth
Solution Approach 1:
The patent segments the WCMs into different groups (first plurality and second plurality of WCMs) and assigns them to connect to different base stations. This segmentation prevents multiple WCMs from competing for the same bandwidth resources at a single base station, thereby resolving the contradiction between maintaining connectivity and achieving high data transmission rates.
Solution Approach 2:
The patent introduces a new dimension of spatial diversity by directing antenna elements of different WCMs toward different base stations located in different geographical directions. Instead of all WCMs competing in the same frequency band at one base station, the system expands the connection space to multiple base stations, effectively increasing the available bandwidth for data transmission.
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 introduces a database as an intermediary that stores and manages information about antenna characteristics, base station locations, and frequency band assignments. This database enables the system to intelligently assign different frequency bands to different WCMs connecting to different base stations, thereby reducing interference while maintaining manageable device complexity through automated resource allocation.
3Adaptability or versatility
If antenna elements are made rotatable and tiltable to optimize connections, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent implements rotatable and tiltable antenna elements that can dynamically adjust their orientation to optimize signal reception and transmission toward different base stations. This dynamic adjustment capability allows the system to adapt to changing network conditions and geographical locations, improving connection quality while the control system manages the complexity of the mechanical adjustment mechanisms.

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.
