Demonstration Abstracts 

Functional Level Virtualization Prototype for 5G Core Networks: The core networks are evolving from Evolve Packet Core (EPC) in 4G to Service-Based Architecture (SBA) in 5G as that defined in 3GPP Release 15. For this evolution, we have developed RECO, a Reconfigurable Core Network for future 5G communication systems ( With RECO, a network component can use different modules at the same time or change modules at execution time for different applications or services to achieve the vision of network slicing and functional level virtualization in fine grain. This demonstration shows the prototype that we have implemented for RECO. We will demo RECO with real commercial UEs and a real commercial LTE small cell eNB. We will demonstrate the functional level virtualization technology, which is important to level up the flexibility of future 5G core networks.

‘One-click-deployment’ of a Truly Cloud-Native End-to-End cellular network solution over hybrid clouds-Infrastructure: 5G must become the ubiquitous fabric blending universal connectivity (to humans, robots, sensors…) with cloud versatility and scalability. For realizing this vision, the Platform-As-A-Service (PaaS) model is adopted.

PaaS promises to deliver network services and applications with higher agility and performance through “ancillary services” – scalability, high availability, state management, controllers, orchestrator… – provided once by the PaaS. Developers and service providers can therefore concentrate on their applications and businesses and improve time to market.

To solve the “one size does not fit all” dilemma, instead of building an “end-to-end hard-wired” solution (as it is the case now in the market) we adopt the “build-to-order” paradigm that best matches the business, latency, throughput… requirements thanks to the platform “composability”. A component is an extension of the Reusable Functional Block (RFB) abstracting various virtualization (VM, containers, unikernels) & acceleration (GPU, FPGA, packet processors) technologies. Thanks to RFB, we can ‘build-to-order’ platforms suiting targeted use-case: platforms are made of VNFs (RAN, CORE, MEC, Video application, xHAUL…) and well-selected ancillary (orchestrator, intent-based controllers, message bus…) components.

This demonstration shows a “one-click-deployment” of an end-to-end cellular network over a distributed infra-structure FRONT-END/EDGE/CENTRAL/PUBLIC clouds:

  • RAN is split in two components (Central Unit/Distributed Unit) running in FRONT-END and EDGE clouds respectively,
  • xHAUL connecting FRONT-END and EDGE clouds supports intent-based networking,
  • CORE is split in four components running in PUBLIC cloud (Amazon Public Cloud),
  • Ancillary services (orchestrator, SDN controller) are optimized to make the Platform-As-A-Service (PaaS) telco-grade.
  • All components (VNF and ancillary) are deployed on-demand.

Distributed Multi-User MIMO network with multi-antenna devices using SDRs: This demonstration shows the working of a distributed MU-MIMO (D-MIMO) based Wi-Fi (802.11ac compliant) network using SDRs (USRP B210s and X310s). D-MIMO synchronizes and coordinates the transmissions from spatially separate Wi-Fi access points (APs) to facilitate multiple simultaneous transmissions in the downlink. Four USRP B210s, located in four corners of the testbed, are used as Wi-Fi APs, which are synchronized using an external octo-clock. Wi-Fi users are distributed throughout the testbed. Novel algorithms for user selection in the downlink are proposed and implemented. Experiments describe the merits of using D-MIMO compared to state-of-the-art configuration and the associated implementation challenges.

Uplink packet detection and demodulation of OFDM frames for a Massive MIMO system using CPU and GPU: This demonstration shows the demodulation of the OFDM symbols for a Massive MIMO system using GPU at the back-end. The demo contains users (B210s), which are situated on all 4 corners of the testbed, sending OFDM frames to the Massive MIMO system (16 antennas, 8 X310s), which acts as a Base Station (BS) situated in the corner of the testbed. The back-end of the BS consists of CPU and GPU. The performance of CPU and GPU for channel estimation and demodulation of OFDM symbols is compared with variation in parameters such as FFT length and number of channels.

Massive MIMO Development Platform and RF Channel Emulator: Massive multiple-input and multiple-output (MIMO) is one of the key technologies in the fifth generation (5G), both in sub 6GHz and in mmWave, providing 10X or more spectral efficiency through spatial multiplexing and improving coverage by beamforming. Radio frequency (RF) channel emulators capable of supporting 64×16 or higher Multi-user MIMO are needed in to development, optimization and evaluation of massive MIMO 5G base stations. In this demonstration, a complete massive MIMO development platform and RF channel emulator with 3GPP massive MIMO channel models will be demonstrated. This platform includes a base station emulator, a RF channel emulator and a user equipment (UE) emulator capable of emulating multiple UEs, each of which has its own independent channel models.
