5G Demos and Trials
FITUR 2018 has been the presentation platform for a series of technological solutions aimed at the tourism industry and fair management, ready to spring into action with 5G technology, that have been developed by a multi-disciplinary team of researchers who have been working at the IFEMA LAB 5G laboratory, set up by IFEMA and 5TONIC.
IFEMA demo at FITUR 2018 is a first prototype in what is going to be the first “Augmented Trade Fair” model, intended to transform the experience of visitors and exhibitors based on a set of solutions that will reinforce user interactivity and will provide an environment of immersion in which to develop activities. The “Augmented Trade Fair” solution and the set of prototypes were shown at the IFEMA LAB 5G stand, located in the North hall of FITUR. They include elements of personalisation, planning and smart virtual assistant guidance, holographic interaction with other people who are exhibiting or attending FITUR, or connected to it, and the possibility of reviewing all the activities performed as well as content with 100% digital access.
The prototypes developed at the IFEMA LAB 5G are conceived to become commercial solutions in the short-term, making maximum use of the features of current technologies and virtual and augmented reality systems, the cloud and advanced 4G connectivity. They also have the possibility of incorporating new functions which are expected to be introduced mainly because of the evolutionary potential of 4G technology towards the new 5G network, both regarding hyper-connectivity and flexible distributed computing.
The IFEMA LAB 5G work process
The work process begins with the combination of analytical and creative aspects based on the new “Design Thinking” and “Agile Cycles” design techniques, ultra-fast development methods in which the team of IFEMA and FITUR professionals were also involved, in order to adapt the project to the reality of the fair experience and of the tourism industry.
The second step is the creation of the new “Augmented Trade Fair” concept, coined by the IFEMA LAB 5G research team, based on the combination of three strong technological trends that will become predominant within the next 15 years: Mixed Reality, Distributed Cloud and 5G.
Mixed Reality is the combination of Virtual Reality (VR) and Augmented Reality (AR) which enables users to see the real world (as in AR) at the same time that they are seeing virtual objects (as in VR). The virtual objects are anchored to points in real space, making it possible for the user to treat them as “real”. This allows for endless advanced digital applications.
Distributed Cloud aims for a unified focus that will allow for both centralisation and decentralisation of computing resources, as well as optimising the use of access network connectivity and transportation. These will open possibilities of flexibly localising the running of intensive computing applications such as the case of VR/AR applications, improving their features, especially latency, by making the use of network resources and remote computing resources more efficient.
The IFEMA LAB 5 G stand and demo at FITUR
The stand’s structure, containing a guided circuit and an exhibition area, immersed the user in a futuristic and social route through the “Augmented Trade Fair”; a simulation that represented a visit to two points at the FITUR, and provided two different experiences: Augmented Fair Circuit and Mobile Zone.
The first experience, or “Augmented Trade Fair Circuit” will take place with Hololens glasses, which will enable a holographic circuit, in order to simulate a commercial visit at FITUR and offer all of the assistance systems until the mission is completed.
This experience is divided into stages, depending on the point of the circuit where the users are at. It starts off with a tutorial on the Hololens interface, to then give way to a personalised welcome application, and to a standard robot-type assistant that will be the guide for the purpose of the visit. A map of FITUR 2018 showed information on each of the halls and will allow the choice of stand to be visited depending on the interests that were expressed to the assistant. The approximate time to the chosen stand is given, as well as the path to be followed, with a 3D model and audio, and the person to be contacted may be chosen, in communication with a database. The circuit also includes augmented publicity models.
When the destination is reached, the user can look at the augmented stand and, in other words, the products, informative displays, etc. can be shown holographically with attractive animations. The personal guide will at that point become the stand exhibitor and will explain the benefits of the target product. The user will become acquainted with the products detailed on the interface and can enjoy the 3D models, videos, photos, etc. The experience will end with the completion of the negotiation and the signing of the contract.
The second experience took place in the Mobile Zone and it offered augmented and holographic reality demos through smartphones. Among these, 360⁰ video applications to see places in Madrid, or a “Portal” that will transport the user to Madrid to see its monuments and to interact with them and get to know the monument’s details through their mobile, with a high degree of freedom.
This integrated demo will interconnect different transport technologies carrying backhaul traffic, fronthaul traffic and both in one network, which demonstrates the 5G-Crosshaul data plane technologies developed in the project. The traffic of backhaul and fronthaul for different functional splits are multiplexed and/or aggregated via XPFE and XCSE. In particular, two types of mmWave-based transport solutions will be examined in this experiment, including backhaul/fronthaul (PDCP-RLC split) multiplexing with EdgeLink, and a mmWave interface incorporated with fast forwarding techniques handling fronthaul traffic with MAC-PHY splits. The traffic of two types of transport links will be independently fed into the XCSE with physically separate ports. On the other hand, compressed and packetized fronthaul (CPFH) will be applied to reduce bandwidth requirement of fronthaul traffic with a PHY-RF split. Also, backhaul traffic for a LTE eNodeB is considered. The multiplexed backhaul/fronthaul traffic will be injected into a XCSE and integrated switch, which will pass the traffic to BBU for lower-layer split (CPRI and CPFH), BBU for upper-layer split, and EPC in accordance to the functional split profile. An Integrated transport network that multiplex traffics with multiple functional splits will be demonstrated, and performance metrics such as latency jitter and throughput will be measured.

5TONIC partners Telefónica, IMDEA Networks, University Carlos III Madrid, and Cohere Technologies announced on September 28th that the companies have cooperated in a number of successful trials to test Cohere Technologies’ OTFS waveform, a new radio technology that has been proposed for 5G radio interface in 3GPP.
Orthogonal Time Frequency and Space (OTFSTM) is a new wireless modulation technology developed by Cohere Technologies that implements a 2-dimensional representation of the wireless channel, making all wireless transmission under any conditions resilient to channel dynamics.
For these purposes, 5TONIC administered tests during four days where several links with different lengths and propagation conditions were established at different locations including IMDEA Networks premises, University Carlos III, Leganés Campus, and Telefónica headquarters at Distrito Telefónica, which are expected to be representative of different operational conditions.
Additionally, indoors measurements were also carried out in order to assess OTFS capacity to cope with rich multipath propagation conditions. These tests demonstrated that OTFS is compliant with the regulation on potential interference on users of adjacent spectrum. The results obtained fulfilled the targets set up by the participants and set the basis for further cooperation between them.
The tests conducted by 5TONIC were mainly intended to assess the suitability of OTFS based radio equipment for supporting fixed wireless access, a potential 5G use case that Telefónica and other operators are actively exploring.
A demonstration of technological advances by the project 5G-Crosshaul was made to Telefonica officials on October 4th, 2016, at IMDEA Networks Institute.
At this event Ericsson showed new integrated demos over equipment developed as part of the European 5G-Crosshaul project and located at the 5TONIC Research & Innovation Laboratory. Ericsson is one of twenty-one partners of the 5G-Crosshaul consortium as well as a member of 5TONIC.
The 5G-Crosshaul project aims to develop a 5G integrated backhaul and fronthaul transport network that enables a flexible and software-defined reconfiguration of all networking elements in a multi-tenant and service-oriented unified management environment.
This demo shows the possibility to share CPRI traffic and Ethernet traffic in the same link connecting RRUs and BBUs. This functionality will reduce the investment for network operators, which will have a big impact to adopt future 5G networks.
Ericsson Italy and Sweden, under the umbrella of the 5G Crosshaul project, present a joint and integrated demo where both fronthaul and backhaul traffic share a common infrastructure. Their agnostic cross point switch allows to mix traffic generated from CPRI clients with Ethernet client signals.
Ericsson plans to integrate their solution with other partners in the project, but some preliminary tests will be done to connect other equipment, in order to check the feasibility to inject ethernet traffic from other sources.
This demo will be shown in the first audit of the project 5G-Crosshaul, and demonstrates the feasibility of integrating the fronthaul and backhaul. Furthermore, it validates one of the main objectives of the project.
The Open Networking Forum (ONF) is organizing a Proof of Concept (PoC) which will be celebrated between the 7th and 16th of October at IMDEA Networks Institute.
The PoC is presented by the Wireless and Mobile Working Group, and its main objective is to collect and use cases and determine architectural and protocol requirements for extending ONF based technologies to wireless and mobile domains. Areas of interest and pertinence include optimization and management of various network types including wireless backhaul, cellular Evolved Packet Core (EPC) - which entails traffic management, traffic steering, and network security - IEEE technologies such as OmniRAN, and unified access and management across enterprise wireless and fixed networks. This WG will work closely with other technical WG’s within ONF to determine architecture and OpenFlow protocol issues and suggest extensions to ONF specifications to support wireless and mobile use cases. It also intends to collaborate with other standardization bodies to further enhance and promote the use of OpenFlow and OpenFlow-based SDN solutions.
The PoC to be held from the 7th to the 16th of October deals with Wireless Backhaul, an area of great interest for professional vendors, who aspire to integrate OpenFlow extensions to their equipment, as these have already proved to provide efficient support in real-life cases. To date, the participants are: Ceragon, Huawei, SIAE, Ericsson and NEC (MW equipment), Coriant (routing/switching), ONOS (controller), Telefonica (operator) and IMDEA Networks/UC3M in the role as host.Impact:
Network Functions Virtualization (NFV) is currently one of the most revolutionary technologies in the ICT sector. NFV can be defined as the principle of separating network functions from the hardware they run on by using virtual hardware abstraction (definition taken from ISG NFV under the ETSI Standardization organ).
With a view to introducing more professionals and students to this intriguing research field, University Carlos III of Madrid opened the doors for a two-day workshop in June 2015. The workshop was first and foremost intended for Developer profiles, and thus largely enters into detail about technical aspects and foundations, providing a practical training to configure a NFV environment and learning the use of the main toolkits for the development of virtualized network functions. The final goal was to achieve the ability to develop an example and to be able to test it into a NFV environment and even deploy it over the Telefónica NFV Reference Lab.
Although the workshop was only for two days, we managed to provide a deep insight and understanding of these NFV technologies. It should also be underlined that the NFV Developer Sessions of the training program was designed for developers with knowledge or background experience in the fields of basic C, basic Linux, Virtualization technologies, basic networking knowledge, and basic knowledge on computing.
