+== OpenAirInterface(OAI) 5G Network with COTS UEs ==
+
+
+
+=== Description ===
+This tutorial contains instructions for setting up [https://openairinterface.org/ OAI] 5G NR network using COTS user equipment in COSMOS testbed.
+Amarisoft provides software based gNB, 5GCore (eNB,EPC), and UE simulator that run on commodity off-the-shelf devices. A typical software-based cellular basestation/UE consists of a host PC and an SDR, where host PC is used for processing the baseband signals sent to and received from the SDR. Amarisoft supports various SDRs including USRPs such as N310, X310.
+In this tutorial, we run 5GCore, gNB(SA) on a host server+USRP N310 in COSMOS SB1. The UEs used in this experiment are
+
+1)SIMCOM SIM8200EA-M2 USB modem on sdr1-in3.sb1.cosmos
+
+2)OnePlus8T KB2005 phone (remotely accessible on srv1-in3.sb1.cosmos)
+
+
+=== Prerequisites ===
+In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS [wiki:GettingStarted getting started] page to get started. 
+
+=== Resources required ===
+1 server, 1 USRP N310 for the base station and sdr1-in3 or srv1-in3 to access the UE in [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1 COSMOS SB1] domain
+
+=== Tutorial Setup ===
+
+Follow the steps below to gain access to the [wiki:/Architecture/Domains/cosmos_sb1 sandbox 1 console] and set up nodes with appropriate images. 
+ 1. If you don't have one already, sign up for a [https://www.cosmos-lab.org/portal-2/ COSMOS account]
+ 1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on sandbox 1
+ 1. [wiki:/GettingStarted#LogintoyourReservation Login] into sandbox 1 console (console.sb1.cosmos-lab.org). 
+ 1. Make sure all the resources in the domain are turned off:
+{{{#!shell
+omf tell -a offh -t system:topo:allres  
+}}}
+ In this tutorial, for the Amarisoft base station we will be using the SB1 server srv2-lg1, and the USRP N310 sdr1-s1-lg1. 
+ 1. Load amarisoft-tutorial-cosmos.ndz on srv2-lg1.  
+{{{#!shell
+omf load -i amarisoft-tutorial-cosmos.ndz -t srv2-lg1
+}}}
+ 1. To access the UE, Waveshare SIM8200 USB modem connected to sdr1-in3, load the image waveshare-sim8200.ndz on sdr1-in3. This image has the SIMCOM network drivers installed to control the modem.
+{{{#!shell
+omf load -i waveshare-sim8200.ndz -t sdr1-in3
+}}} 
+ 1. To access the phones connected to srv1-in3, load the image vysor-cosmos.ndz on srv1-in3. This image has [Vysor https://www.vysor.io/] and chrome remote desktop client installed in order to provide remote access to the phones.
+{{{#!shell
+omf load -i vysor-cosmos.ndz -t srv1-in3
+}}}
+ 1. Turn all the required resources on and check the status
+{{{#!shell
+omf tell -a on -t srv2-lg1,sdr1-s1-lg1,sdr1-in3,srv1-in3
+}}}
+{{{#!shell
+omf stat -t system:topo:allres
+}}}
+
+=== Tutorial Execution ===
+[[CollapsibleStart(Run the Amarisoft base station)]]
+==== Check the USRP ====
+* Log in to the server srv2-lg1 with 2 SSH sessions.
+{{{#!shell
+ssh root@srv2-lg1
+}}}
+* Upon logging into the server, run eth_config.sh. This sets up the 10G data interfaces DATA1, DATA2. After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per this [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment table]. The server should then be able to access the USRP N310 sdr1-md1 which can be checked by running uhd_find_devices.
