 == Description ==
-This experiment runs oml2-iperf on two nodes and collects bandwidth measurements along with the controlled attenuator values. The RSSI seen by the wimax node interface is varied by controlling this attenuator value. At different attenuator values we can measure the down link throughput for the iamx interface.

-== Hardware Requirements ==
-1. ''Sandbox 4 node1-4'': runs oml2-iperf as server.[[BR]]
+== Hardware utilized ==
+1. ''Sandbox 4 node1-4'': runs oml2-iperf as server. The wimax interface card is used for measurements.[[BR]]
 2. ''Sandbox 4 node1-9'': runs oml2-iperf as client.[[BR]]
+3. ''RF-attenuator matrix'': this used by the script to attenuate the air interface between the wimax base station and node.
 
-== Software Requirements ==
-1. ''baseline-iperf.ndz'': disk image that's loaded onto the nodes.[[BR]]
-2. ''oml2-server'': this is server running on sandbox4
+== Software requirements worth mentioning ==
+1. ''baseline-iperf.ndz'': disk image that's loaded onto the nodes. This image is loaded with oml2-iperf.[[BR]]
+2. ''oml2-server'': this is a server running on sandbox 4 which collects measurement data from oml2-iperf.[[BR]]
 
 == Set up procedures ==
+Getting started, ssh into the console of sandbox 4.[[BR]]
+Verify the oml2-server is running: '''$ ps -elf | grep oml2-server'''
