 The goal is familiarize with the [[https://project.inria.fr/ephyl/|EPHYL Project]] GNU Radio framework, understand it, and try some stuffs.
+**REMINDER**: If you you have never used GNU Radio Companion (GRC), it is **HIGHLY** suggested that you go check some [[tutorials|tutorials]]. Especially Tutorial **3** and **6**
 When connected to CorteXlab (aka Airlock server), create a new directory "stage1", copy this folder and put it in your home :

+Start experimenting and try to get some results as in the local tests.
+Maybe you'll have to strengthen the processing in the uplink transmission (modify some parameters, thresholds, etc)
-Start your experiment and evaluate the transmission quality.
+**UPDATE For Wednesday 21 :**
-Maybe you'll have to strengthen the processing in the uplink transmission !
+If you have some difficulties creating GRC flowgraphs, you can get an example for each node here:
+<code>
+yourlogin@srvairlock:~$ mkdir stage2
+yourlogin@srvairlock:~$ cp /cortexlab/homes/ooubejja/ws/cxlb stage2/
+yourlogin@srvairlock:~$ ls stage2/cxlb
+</code>
+In stage2/cxlb you should have these files now:
+<code>
+A.txt             ephyl_bs_core.py  ephyl_sensor.py           main_bs.grc      scenario.yaml
+B.txt             ephyl_bs.grc      ephyl_sn_sched.py         main_bs.py       tag2msg.py

+data_slot_mux.py  ephyl_sensor.grc  file_source_slot_ctrl.py  main_sensor.py
+</code>
+Open ''main_bs.grc'' and ''main_sensor.grc'' in GNU Radio, some parameters are already set to match CorteXlab setting (UHD blocks, generation options, reference source,etc). However, you should verify RF parameters (Freq, gain, sample rate,etc).
+Also, don't forget to adapt ''scenario.yaml'' to your actual scenario.

 The proposals can be relevant to :  PHY/MAC layers, data compression, channel coding, throughput, interference management, etc.
-Finally, keep in mind that, even after the Winster school, you can continue working on the framework (or anything else) anywhere and anytime, since you have your personal FIT/CorteXlab account.
