Solution Overview
Problem
Current xDSL technologies face inefficiencies in data communication at the customer-premises equipment due to lack of mechanisms to enhance data processing efficiency, particularly in handling upstream traffic and managing crosstalk interference, which limits bandwidth and reliability.
Innovation Solution
Implementing a method that utilizes multiple interfaces, including wireless, powerline, and wired connections, to distribute traffic and establish ad-hoc networks between customer-premises equipment, allowing for load-sharing and increased bandwidth by connecting through multiple channels, thereby overcoming bottlenecks and ensuring resilience against connection failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single interface is used for data communication at CPE, then device complexity is reduced, but bandwidth and data communication efficiency are limited
Solution Approach 1:
The patent combines multiple interfaces (DSL interface and wireless interface) at the CPE to create a unified communication system. The CPE merges the broadband connection from the DSL interface with the wireless connection from the wireless interface, allowing data to be distributed across both interfaces to achieve higher overall bandwidth and efficiency.
Solution Approach 2:
The CPE is designed to perform multiple functions by supporting both DSL and wireless interfaces simultaneously. It can handle both wired broadband communication and wireless communication, making it a multi-functional device that adapts to different communication requirements and provides flexible data transmission paths.
2Reliability
If multiple interfaces are implemented at CPE, then bandwidth and reliability are improved, but device complexity increases
Solution Approach 1:
The patent implements redundancy by providing alternative communication paths through multiple interfaces. If one interface fails or experiences poor conditions, the system can switch to or distribute traffic through the other interface, providing a cushion against connection failures and improving overall reliability.
Solution Approach 2:
The CPE acts as an intermediary that manages multiple interfaces and coordinates traffic distribution between them. It mediates between the network and various communication channels, intelligently routing data through the most appropriate interface based on current conditions, which simplifies the management complexity.
3Productivity
If traffic is concentrated through single interface, then device complexity is minimized, but bandwidth utilization is insufficient
Solution Approach 1:
The patent segments the data traffic into different streams that can be transmitted through different interfaces simultaneously. Instead of concentrating all traffic through a single interface, the system divides the data flow and distributes portions through the DSL interface and wireless interface, thereby utilizing the total available bandwidth more effectively.
Solution Approach 2:
The patent adds another dimension to data transmission by introducing a wireless interface in addition to the traditional DSL interface. This creates a multi-dimensional transmission architecture where data can flow through multiple parallel channels, increasing bandwidth utilization without significantly complicating the core transmission mechanism.
4Adaptability or versatility
If ad-hoc network is established between CPEs, then network versatility is improved, but network complexity increases
Solution Approach 1:
The patent enables CPEs to automatically establish ad-hoc networks with each other without requiring complex manual configuration. The system provides self-service capabilities where CPEs can autonomously discover, connect, and coordinate with neighboring CPEs, thereby improving network versatility while minimizing the complexity burden on users.
