Spatially Separated IAD Modules for Optimal Mobile Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integrated access devices (IADs) face limitations in achieving optimal mobile radio connections due to frequency constraints and alignment requirements, which hinder the effective use of mobile radio data connections in conjunction with DSL connections, especially in rural areas where DSL bandwidth is insufficient.
Innovation Solution
An integrated access device with a modular structure comprising a home network module, a broadband network module, and a cellular network module, where the cellular and broadband network modules are spatially separate but connected via a local area network, allowing for intelligent routing of data traffic based on load and rules, and featuring independent power supplies and optional Power over Ethernet for flexible placement and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the IAD is positioned near a window for optimal mobile radio reception, then mobile data rate is improved, but installation flexibility and ease of operation deteriorate
Solution Approach 1:
The IAD is divided into two spatially separate modules: a broadband network module (containing DSL interface and power supply) and a mobile radio network module (containing antenna and cellular interface). This segmentation allows the mobile radio module to be positioned near windows for optimal signal reception while the broadband module remains near the DSL connection point, resolving the contradiction between reception quality and installation flexibility.
2Productivity
If the IAD is repositioned or connected via extension cords to achieve optimal mobile reception, then mobile data rate is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines the broadband network module and mobile radio network module into a single integrated access device with unified routing functionality. The router module intelligently combines traffic from both DSL and mobile connections, allowing the system to function as a cohesive unit while maintaining spatial separation of components. This merging approach avoids the need for complex external connections while achieving optimal reception.
3Reliability
If external antennas are connected via coax cables to improve mobile reception, then signal quality is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The antenna function is extracted as a separate, removable component that can be optimally positioned and connected to the mobile radio network module. This allows the antenna to be placed in the most favorable position for signal reception without requiring complex cable management or permanent installations, thereby improving signal quality while maintaining installation simplicity.
4Ease of operation
If spatially separate modules are used for broadband and mobile network functions, then installation flexibility is improved, but device complexity increases
Solution Approach 1:
The router module is designed with universal routing capabilities that can handle traffic from both DSL and mobile connections, as well as coordinate between spatially separate modules. This multi-functional design allows the system to manage complex spatial configurations through a single, intelligent routing component, thereby reducing overall system complexity while maintaining installation flexibility.
