README.txt

+The OpenAirInterface software is composed of four different parts: 
+
+openair1: 3GPP LTE Rel-8 PHY layer + PHY RF simulation
+
+openair2: 3GPP LTE Rel-9 RLC/MAC/PDCP and two RRC implementations
+
+openair3: some networking scripts 
+
+openairITS: IEEE 802.11p software modem (all layers)
+
+targets: scripts to compile and lauch different system targets (simulation, emulation and real-time platforms, user-space tools for these platforms (tbd)) 
+
+see README files in these subdirectories for more information
+
+see also https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/WebHome
