DSL Modem Wireless Coupling for LTE Mobile Radio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for establishing communication between DSL and mobile radio devices, such as LTE and HSPA, face challenges in rural areas where in-house mobile phone coverage is inadequate, requiring expensive coaxial cables or limited USB extension cables, which are not feasible for longer distances.
Innovation Solution
A device and method for DSL-LTE/HSPA coupling using wireless interfaces like USB, Bluetooth, or WLAN to establish a connection between spatially separated components, allowing for secure and stable communication by integrating wireless technologies into DSL modems/routers and mobile radio devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If USB extension cable is used to connect DSL modem and mobile radio device, then connection is established, but cable length is limited to five meters
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The DSL modem and mobile radio device establish a wireless connection instead of being physically connected by a cable, thereby eliminating the length limitation of USB extension cables while maintaining connection stability through wireless protocols.
Solution Approach 2:
The patent transitions from a one-dimensional cable connection to a three-dimensional wireless space connection. By using wireless communication technologies, the connection is no longer constrained by physical cable length but can extend through the entire service area covered by the wireless network.
2Reliability
If coaxial cable with outdoor antenna is installed to improve mobile phone coverage, then coverage is enhanced, but installation cost increases
Solution Approach 1:
The patent replaces the expensive coaxial cable and outdoor antenna system with a wireless communication system. This substitution eliminates the need for complex physical infrastructure while providing mobile phone coverage through wireless networks, significantly reducing installation costs.
Solution Approach 2:
The patent uses wireless communication to create a virtual copy of the physical connection infrastructure. Instead of installing physical coaxial cables and antennas, the system uses wireless signals to provide the same connectivity function, reducing material and installation costs.
3Reliability
If DSL modem is placed near APL in basement, then wired connection is stable, but wireless connection quality deteriorates due to distance from mobile radio device
Solution Approach 1:
The patent segments the communication system into two independent parts: a wired DSL connection for stable data transmission and a wireless connection for mobile radio device communication. This segmentation allows each connection type to be optimized independently - the wired connection maintains stability while the wireless connection provides mobility without being compromised by distance.
Solution Approach 2:
The patent introduces wireless communication as an intermediary between the DSL modem and mobile radio device. This intermediary enables the mobile radio device to connect to the DSL network without being physically close to the modem, maintaining both wired stability and wireless connectivity through the wireless intermediary layer.
