Presenter: Nikos MakrisUniversity of Thessaly

FLEX partnership2

New partners have been added in FLEX partnership through two Open Calls.

FLEX partnership3

The FLEX Concept4

¨ Highly Programmable equipment for 4G provided in two manners:¤ ”Commercial” setup, using off-the-shelf BSs, EPCs and

UEs¤ “Open Source” setup, using OpenAirInterface

¨ Evaluating applications and protocols against existing technologies, or completely restructure the existing networking stack.

The OpenAirInterface Platform5

¨ Open-source (hardware and software) wireless technology platforms for deployment of reduced scale mock network ¤ System approach with high level of realism

¤ SDR architecture and full GPP C

¨ Objectives: LTE and beyond in the box ¤ Innovation in air-interface technologies and wireless networking through

experimentation.

¤ Proof-of-concepts through real-time prototypes and scalable emulation platforms.

Project’s Objectives6

¨ Extend FIRE testbeds with 4G and beyond capabilities.

¨ Smoothly integrate new equipment in existing frameworks.

¨ Expose the maximum possible configurability of the resources.

¨ Build mobility functionalities on top of the equipment (real and emulated).

¨ Provision open and remotely accessible testbeds to the community.

Testbeds Available in FLEX7

Equipment in FLEX8

¨ Different types of cells consisting of macro- and femto-cell solutions¤ Femtocells by ip.access, with APIs for configuring them¤ Airspan Macro Cells¤ Core Network by SiRRAN¤ Open5GCore Network by Fraunhofer FOKUS¤ Conformance testbed in Malaga¤ OpenAirInterface cells and core networks for 5G¤ Commercial and Open Source User Equipment

n Huawei/ZTE Modems, Android Smartphonesn OpenAirInterface and srsUE solutions

FLEX Contributions9

¨ Framework extensions for managing the FLEX equipment in a user-friendly manner.

¨ Regardless of the LTEequipment, configuration commands are the same.

¨ Experiment execution by submitting a simpledescription and collecting the organizedresults.

¨ Resource slicing so that theycan be used concurrently by multiple experimenters (as a Service).

Open Calls in FLEX10

¨ Two Open Calls for projects¤ 21 new partners through the Open Calls

n Infrastructure extensions and integrationn Innovative experiments

¨ 1.8M total funding for Open Calls

Research Focus in FLEX11

¨ Mobile Edge Computing¤ Allow applications to run at the network edge¤ Delivering enhanced Quality of Experience, lowering

traffic volume in the backbone network, reduced latency times, etc.
