Comparing Hybrid access networks solutions

Denis Périquet

To cope with growing user appetite for bandwidth, telecommunication network operators are exploring various solutions to combine different access network technologies together. This will pave the way for hybrid access networks, i.e. access networks that combine very different technologies such as DSL and LTE. In this white paper, we compare different technical solutions that can be used to create such hybrid access networks. In particular, we compare the benefits of the Multipath TCP-based solutions to network-layer solutions. Furthermore, our measurements done on three widely deployed DSL access routers show that a software-based solution using Multipath TCP can achieve high bandwidth on existing devices

MPTCP : Opening the way for 5G Convergence

Graham Turnbull

In March 2019, we published a paper entitled “Opening the way for convergence in the 5G Era with MPTCP” to talk about upcoming features in 3GPP Release 16 and specifically the role of the Tessares proposed 0-RTT Convert Protocol as the basis for ATSSS. Since then a lot has happened.

Hybrid access as an upgrade to fixed wireless

Graham Turnbull

Some operators are rolling out Fixed Wireless Access (FWA) which implies connecting TV's, laptops, phones, tablets, and smart home controls to the Internet over wireless networks. We propose supplementing FWA with fixed line connectivity using our hybrid access solution to offload traffic from the wireless network and to ensure consistent service for end users

Can 4G networks provide broadband services?

Olivier Bonaventure, Graham Turnbull

Broadband services are now as important as electricity for most households. In some countries, good network connectivity is an important consideration when buying a house or an apartment. The importance of always-on broadband services will continue to grow in the near future. Broadband services are typically provided by fixed networks using either xDSL or cable technologies but some operators have deployed fixed services based on mobile networks. This article looks at the suitability of 4G networks as the main connection to the Internet.
