Method and device for data processing and communication system comprising such device

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention proposes a method and device for improving data communication over digital subscriber lines (DSL) by applying multiple-input-multiple-output (MIMO) processing techniques at network components. The main feature is to reduce or cancel crosstalk and interference between wires in large cable bundles, allowing for improved data transmission rates and reliability. This can be implemented either centrally in a network hub or distributed across line cards in existing telecom infrastructure, often just by a software or firmware update.

Use CasesContent extracted from patent full text and abstract with AI.

• Enhancing VDSL2 and xDSL broadband connections, providing users with higher speeds and more reliable service.
• Upgrading telephone company infrastructure to support high-bandwidth services like IPTV, HD video streaming, and high-speed internet without replacing physical cables.
• Telecommunication operators deploying advanced crosstalk cancellation in DSLAMs (Digital Subscriber Line Access Multiplexers) for better performance in dense urban areas.
• Retrofit solutions for existing DSL networks to address performance degradation due to crosstalk without expensive hardware overhauls.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly improves broadband speed and stability on existing copper wire infrastructure by reducing crosstalk interference.
• Enables easy upgrades of deployed network hardware, sometimes via software updates, minimizing downtime and capital expenditure.
• Compatible with current DSL standards and infrastructure, allowing roll-out without major changes or new cabling.
• Flexible deployment options: both centralized and distributed processing architectures are supported, adapting to different network layouts and operator needs.
• Supports plug-and-play operation, automatically identifying problematic connections and optimizing crosstalk cancellation accordingly, making maintenance and upgrades easier.
