 == Wifi Tutorial: Access point with multiple clients ==
 
-This tutorial shows how an experiment script configures an access point  (AP) and multiple clients for performance testing with iperf. In this experiment script we'll use an OMF feature to define an application header for iperf and run this application on the AP and access points.

 === Experiment Script ===
 
-The experiment script is shown below. Near the top of the script we define an application header for iperf.  After which we define two groups - the first group (AP) consists of a single node to be configured as an access point. The second group (client) can be single or multiple node(s) to be configured as wifi clients. Both groups add the iperf application and configure the wireless interfaces accordingly. At the bottom of the script, the nodes in the all the groups are brought up and the applications are executed.

 === Executing the Experiment Script ===
 An overview on running experiment scripts on the orbit testbed can be found on the [wiki:Documentation/CGettingStarted Getting Started Page]. 
-In order to run this experiment script, load ''baseline.ndz'' image on nodes with wifi cards. Check the ''Status Page' on the [https://www.orbit-lab.org/cPanel/controlPanel/start Control Panel] to select any particular type of wifi card.

-nilanjan@console.grid:~/EXP$ omf load -i baseline.ndz -t node15-1,node16-1,node17-1,node19-1,node20-1

 After the nodes have finished imaging, turn the nodes on. The topology used here is ''system:topo:imaged'' which selected the prior set of node that were successfully imaged.

 To run this experiment with 2 clients nodes:
 {{{
