Thanks to Raphael Defosseux <firstname.lastname@example.org>, we are delighted to announce that the lastest version of OpenAirInterface (OAI) EPC and RAN are available (and will be periodically refreshed) with docker images specific to the R2lab testbed. To automatically deploy those images, checkout the r2lab-demo code through
git clone https://github.com/fit-r2lab/r2lab-demos.git and follow the steps described in the
- deployed 2 boxes based on B-205 USRP hardware with duplexers (one for UE and one for eNB)
- new images for
rhubarbe images centos-8 fedora-31for their status
- part of the OpenAirInterface's CI run on a nightly basis on R2lab
- the federation link with Fed4Fire, that had been down for a couple years due to some nasty MD5-signed certificates, is live again. Fed4Fire users can make reservations throught Jfed again.

R2lab participates in the 1st joint Grid5000-FIT school, triggered as the first public milestone of the SILECS project.
people interested in following the hands-on session on R2lab should start here.
- a second commercial phone - type Moto E - is available in the chamber
The code for the testbed has been split into the following git repos:
- a collection of internal utilities as r2lab-misc
As a reminder, the code for
nepi-ng currently sits here:
demos/subtree in the
r2labgithub repo was split and moved into a separated repo named r2lab-demos
- a mybinder shell has been setup to host notebooks in one-click, like e.g. our radiomap application
- some nodes feature a LimeSDR device
- so-called nightly procedure, that probes the testbed for failures, is reinstated to run on a bi-weekly basis
- some nodes now feature a USB-based LTE dongle
- the openair demo is given during the SIGCOMM-2017 demo session
- the Dell physical server that hosts the r2lab service VMs is upgraded and now runs a HTML5-based DRAC interface, causing a 2-hours scheduled outage of the testbed
- the radiomap demo gathers all-pairs communication conditions, see
visumapon how this can be visualized in a jupyter notebook
- Running new architecture based on PLCAPI instead of omf_sfa
- Previous contents (accounts, slices, keys...) has been migrated automatically
- Slice names have changed a little, to be completed
- All tutorials now point at
nepi-nginstead of deprecated
Slides available below:
- OpenAirInterface images for deploying infrastructures and eNodeB's are available under the names
u14.319-oai-enbfor eNodeB's and scramblers and such
u14.48-oai-gwfor infrastructure services like Home Subscriber Server (HSS) and Evolved Packet Core (EPC)
- We have now 6 nodes equipped with USRP's
- We have been working on a replacement for NEPI
- We have published 2 python libraries on pypi
- We have our first workable script that uses this combination of tools for running an experiment on R2lab
- This new paradigm runs several times faster than the initial NEPI-based version.
- upgrade of the physical server
upgrade of its web companion VM
this means both hosts can take

- The R2lab team pays a visit to our colleagues of FIT/CorteXlab at INSA Lyon
- Both faulty nodes 4 and 18 are shipped back to Greece for troubleshooting by the manufacturer
- Node 18 is set aside and replaced with a spare node (no impact for users)
- All nodes deemed sustainably operational
- Nightly routine now is from 3a.m. until 4a.m.
- New tutorial video! Setting up an OpenAirInterface-based 5G infrastructure, and a tour in the chamber using Skype on a commercial NEXUS phone.
- Check it out, here
- Replacement of battery on nodes 7, 14, 18, 29 and 30 to deal with hang issues when restarting.
- The 3d printed boxes are ready to ship
- Start progressive rollout of a new layout for antennas
- Antennas to be aligned in a row, on a north-south line (relative to the livemap, not geographically)
- And spaces on a 3cm basis (although this seems a little too wide)
- Start Progressive deployment of Intel 5300 cards.
- Target is one Atheros and one Intel on each node
- Ordered 3d-printed boxes to contain cards as they cannot be seated inside the box

- Reception of USRP-oriented extensions of the CMC cards
- Related firmware version is 3.2.
- Deployed on only a couple nodes for now
December 20, 2015
- Announcement of global availability; the testbed is now open to public use.
Deployment of rhubarbe as a replacement of
omf6for managing node images. New features include
- written in python 3 / asyncio which results in a single threaded asynchroneous application
- which makes it much more efficient than its ruby ancestor (can load all 37 nodes in parallel without a glitch)
- and more reliable too (always exits if timeout expires for any reason)
- includes a tool to wait for all nodes to be responsive (
- and to inspect current reservations (
- as well as a monitoring tool (this is what feeds the livemap and livetable views
As a result, it is now possible for us to expose a single resource named
37nodesto the onelab portal, thus materializing the fact that the whole testbed is actually reserved
- availability of images based on fedora-23 and ubuntu-15.10
nitos_testbed_rcto run gem 2.0.3 again (with our patches for using latest frisbee) ; 2.0.4 is not working properly for us, loading images is even less reliable than 2.0.3.

- R2lab Platform Live Map : we are working to finish a live map information of the R2Lab platform.
R2lab Platform Status : from today is possible follow the tech details of R2lab platform.
We are monitoring some information from the nodes in the anechoic chamber. Have a look at our status page for details.
