Wireline Network Extension via Wireless Intermediary Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rural areas often lack access to high-bandwidth broadband communication services due to the high cost of expanding conventional wireline networks and geographic obstacles, which conventional fixed wireless communication networks attempt to address but require expensive and proprietary equipment with specialized installation skills.
Innovation Solution
The system extends wireline communication networks using wireless transmission methods that leverage conventional hardware and protocols, allowing for the use of standard modems and optical network terminals, and can operate with low-cost wireline communication nodes, thereby reducing deployment costs and simplifying installation by not requiring modifications to the network core or central elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cable wireline communication networks are expanded to rural areas, then broadband service coverage is improved, but deployment cost increases significantly
Solution Approach 1:
The patent introduces a wireless communication system as an intermediary between the wireline network and remote customers. The wireless system bridges the gap by transmitting data over-the-air to customer premises equipment, eliminating the need to physically extend wireline infrastructure to every rural location while maintaining broadband service delivery
Solution Approach 2:
The patent replaces the mechanical/physical wireline cable infrastructure with a wireless electromagnetic transmission system. Instead of laying physical cables across difficult terrain to rural areas, the system uses wireless signals to deliver broadband service, significantly reducing deployment costs while expanding coverage area
2Area of stationary object
If conventional fixed wireless communication networks are deployed, then broadband service to rural areas is achieved, but equipment cost and installation complexity increase
Solution Approach 1:
The patent makes the customer premises equipment universal by enabling standard devices like modems and wireless access points to function as CPE. These multi-functional devices can operate in both wireline and wireless modes, eliminating the need for proprietary equipment and simplifying installation while expanding service coverage to rural areas
