After a successful nine-month pilot trying out the Multipath TCP (MPTCP) technology in Frasnes-Lez-Anvaing, where a very high satisfaction rating was achieved among Proximus customers as they could enjoy Internet speeds up to 20 Mbps faster than before, Tessares is pleased to announce that its “DSL + 4G/LTE” solution has successfully gone through all the qualification steps needed for country-wide deployment. Proximus, for its part, now plans to upscale this pilot project to a nationwide Live User Test.

Strong partnership between Tessares & Proximus

Proximus has deliberately opted for an open innovation culture and chosen to co-create and work with partners.  It is in this spirit that Proximus regularly looks for solutions with start-ups and universities.

Therefore, in April 2015, Proximus and VIVES II - Louvain Technology Fund - invested in Tessares, a spin-off of the Catholic University of Louvain (UCL) based in Louvain-la-Neuve, which had developed an innovative Hybrid Internet Access technology based on the "Multipath TCP" (MPTCP) protocol. Thanks to this technology, which combines the speeds of existing fixed and mobile networks, it is possible to improve the Internet experience of customers living in rural areas (a long distance away from street cabinets).

From laboratory tests to country-wide deployments

After a study phase and laboratory tests, it was decided that Tessares' innovative MPTCP solution would be monitored and tried out in real-life situations by Proximus customers living in the most remote areas. Therefore, in June 2016, Proximus chose the municipality of Frasnes-Lez-Anvaing to launch a pilot. The idea was to combine the bandwidth of the customer's fixed network with that of the 4G network.

Today, after a successful pilot phase, achieving a very high satisfaction rating among customers, Proximus is pleased to announce that its “DSL + 4G/LTE” solution has successfully gone through all the qualification steps needed for country-wide deployment. Tessares' objective is to become the reference provider for hybrid telecommunications networks.

Willing to constantly improve and offer the best quality networks, Proximus, for its part, plans to upscale this pilot project to a nationwide Live User Test to assess the feasibility of a nationwide commercial launch later in 2017. This is a solution for its customers located a long distance away from a Remote Optical Platform (ROP), where an attenuation effect cancels out the efficiency of VDSL technology. Proximus’ aim is to ensure access to high-speed Internet across the whole of Belgium in line with the objectives of the EU Digital Agenda which aims that, by 2020, all Europeans have access to Internet speeds of at least 30 Mbps, and half of all households enjoy at least 100 Mbps.

The Frasnes-Lez-Anvaing pilot proved a great success, customers are highly satisfied as they can enjoy speeds up to 20 Mbps faster than before giving a much better experience for Internet & multimedia. The successful integration of the Tessares MPTCP solution in our infrastructure has convinced us to deploy the service more widely

Geert Standaert, Proximus CTO

I’m pleased that our Multipath TCP solution has evolved to a high level of maturity, enabling country-wide availability of the service. This standardized technology has been enhanced with path management, giving operators the flexibility to enable intelligent traffic steering for optimized usage of xDSL and LTE assets. In addition, the system has been tuned for high performance on existing home gateways from several vendors, and is fully compatible with NFV, a major telecom trend. We are grateful for the confidence Proximus has shown in the solution which has led to substantial interest from operators across Europe, Asia Pacific and America. Tessares has three operator customers with several more expected during 2017.

About tessares

Tessares is a spin-off from the Université catholique de Louvain (UCL), Belgium where researchers have over a period of many years greatly contributed to the design, implementation and standardisation of a new Internet protocol: Multipath TCP (MPTCP) which is an evolution of TCP, invented 40 years ago and used for over 90% of the world’s Internet traffic. In comparison to alternative solutions, MPTCP offers many benefits in particular in terms of deployability, being simpler and cheaper to commercialise. Although any IP network can be bonded, the initial focus of the company is Hybrid bonding of xDSL & 4G networks for Home/Office Gateways. Tessares is headquartered in Belgium with development and sales teams in Belgium and the UK.
