Joint Demo at Flex5Gware Final Event: “Network split with integrated fronthaul and backhaul”
The CLEEN’17 workshop demo has shown that the 5G-Crosshaul XPFEs are capable of transporting fronthaul and backhaul traffic generated by the Flex5GWare scenario. A video server located in the EPC machine streamed video to the UE, this traffic was encapsulated, forwarded, decapsulated and delivered within the LENA scenario (L2 and above) and also transported to the LTE transmitter (L1) that runs different functional splits showing the energy consumption in real time.
5G-Crosshaul co-organised a Workshop at EuCNC: New x-haul solutions for the 5G transport challenge

Motivation and Background
Future Radio Access Networks (RAN) call for transport networks with unprecedented flexibility and performance. Stringent requirements on bandwidth, latency, and timing as well as the mandatory support of heterogeneous technologies and different functional splits create the necessity for next-generation x-haul solutions. The workshop will discuss 5G transport challenges and new solutions developed within the Horizon2020 projects iCirrus, 5G-Crosshaul and 5G-XHaul.
London, March 30-31 @ 5G PPP Workshop on 5G Architecture and RAN Integration
5G-Crosshaul co-organised a Workshop for sharing, discussing, debating relevant aspects of 5G system architecture and integration of multiple radio access technologies (RAT) at the RAN and beyond. Among other topics:
Arturo Azcorra, Director of IMDEA Networks Institute, Full Professor at University Carlos III of Madrid and 5G-Crosshaul Coordinator, is interviewed, together with other ICT experts, on the topic of 5G communications, at the program «World Ecommerce» of the Spanish radio station «Radio Internacional de España».
The full 55 minute program was broadcast live on March 14th, 2017, from 1:00 pm to 2:00 pm CEST. World E-Commerce is the only radio program in Spanish focused on cross-border e-commerce. It is broadcast in Spain, Argentina, Rumania, Italy, China, South Africa, Lithuania, Serbia, Mexico and Colombia.
The 5G-Crosshaul, The integrated fronthaul/backhaul, part of the European H2020 5G Public-Private Partnership (5G PPP) Infrastructure, held a Plenary Meeting in Turin on the 7th, 8th and 9th of March, 2017.
The 3 full day meeting in Telecom Italia has more than 50 experts from the 20 consortium members (leading telecom industry vendors, operators, IT companies, small and medium-sized enterprises and academic institutions) attending to share their visions and opinions in order to advance in the project objectives, milestones and deliverables.
5G-Crosshaul partner CTTC presented a demo at the Mobile World Congress 2017.
The goal of this demo is to illustrate reliability through the SDN/NFV management and orchestration of constrained 5G backhaul/fronthaul infrastructures (mmWave,Wi-Fi) for the outdoor dense urban scenario. Particularly, this demo features the connection between two transport nodes were a mmWave link (IEEE 802.11ad) acts as primary link technology, whereas a Wi-Fi link (IEEE 802.11ac) acts as a secondary link technology to increase resilience. Forwarding behavior of both transport nodes are configured with Openflow and the configuration of heterogenenous wireless node resources are done through a RESTCONF interface. Network behavior (state, statistics) is monitorised by means of a Graphical User Interface (GUI) running as an SDN application in conjunction with the SDN controller.
In the demo, a 4K video file is transmitted between hosts connected to the transport nodes. Initially, this transmission is done through the mmWave link (primary link). In the event of a link failure, the transport node detecting this anomaly informs the SDN controller, which immediately after switches the transmission to the Wi-Fi link (secondary link). When the transport node reports the recovery of the primary link, the SDN switches again the transmission to the primary link. And all of this without any interruption in the 4K video streaming.
Crosshaul – The fusion of Fronthaul and Backhaul in 5G!
Looking at various research and standardization forums leading the development of 5G, such as 5G-PPP, NGMN, 3GPP, IEEE, ITU, IETF, ETSI, etc., all seem to align on the vision that the fronthaul and backhaul will converge or fuse in 5G into what is now popularly referred to as Xhaul or Crosshaul. So what requirements are driving such a fusion in 5G? Which enabling technologies could make it happen? Where are the remaining gaps and what is the industry doing to make it happen? And when are we going to see it? Featuring leading experts in the industry, this panel aims at discussing the Crosshaul topic from the various angles of requirements, architecture, enabling technologies, standardization, and market deployment.
