# Increasing broadband reach withHybrid Access Networks

## TL;DR

This paper discusses Hybrid Access Networks that combine xDSL and LTE to extend broadband reach cost-effectively, detailing architectures and a practical implementation using Multipath TCP.

## Contribution

It introduces the three architectures defined by the Broadband Forum and shares practical insights from implementing a Multipath TCP-based Hybrid Access Network.

## Key findings

- Successful deployment of Multipath TCP in Hybrid Access Networks
- Enhanced broadband reach in less densely populated areas
- Validation of architectures through real-world implementation

## Abstract

End-users and governments force network operators to deploy faster Internet access services everywhere. Access technologies such as FTTx, VDSL2, DOCSIS3.0 can provide such services in cities. However, it is not cost-effective for network operators to deploy them in less densely populated regions. The recently proposed Hybrid Access Networks allow to boost xDSL networks by using the available capacity in existing LTE networks. We first present the three architectures defined by the Broadband Forum for such Hybrid Access Networks. Then we describe our experience with the implementation and the deployment of Multipath TCP-based Hybrid Access Networks.
