Wireless Device Concurrent Cellular Non-Cellular Link Relaying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely populated metropolitan areas, the limited bandwidth of cellular networks and the lack of space for additional base stations lead to weak or blocked cellular signals in marginal-to-inoperative regions, such as cell edges, hilly terrain, concrete walls, or tall buildings.
Innovation Solution
The use of non-cellular interfaces in wireless devices to concurrently perform multiple wireless connections, exploiting the hybrid of cellular and non-cellular networks to expand cellular coverage by relaying cellular communications through non-cellular networks without interrupting existing connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more cellular base stations are installed to increase bandwidth and coverage, then cellular network capacity improves, but available installation space in metropolitan areas becomes insufficient
Solution Approach 1:
The patent introduces non-cellular networks (Wi-Fi, Bluetooth) as intermediary relay networks. Wireless devices connect to cellular base stations through these intermediary non-cellular networks, allowing cellular communications to be relayed without requiring additional physical cellular base stations in space-constrained metropolitan areas.
Solution Approach 2:
The patent enables wireless devices to perform multiple functions simultaneously: maintaining their primary non-cellular connections while also acting as relay nodes for cellular communications. This multi-functionality allows existing devices to contribute to cellular network capacity without requiring dedicated infrastructure.
2Adaptability or versatility
If wireless devices concurrently perform multiple wireless connections using non-cellular interfaces, then cellular coverage is expanded through relaying, but resource utilization complexity increases
Solution Approach 1:
The patent segments the wireless interface resources into separate virtual interfaces, with each virtual interface dedicated to a specific wireless connection. This segmentation allows the device to manage multiple concurrent connections (cellular relaying and non-cellular communications) independently, reducing the complexity of resource coordination.
Solution Approach 2:
The patent implements dynamic resource allocation where the wireless device can flexibly adjust its role between being a cellular relay node and maintaining its own non-cellular connections. The system dynamically configures the non-cellular interface to perform different functions based on network conditions and device capabilities.
