+= 802.11 Reference Design:  TX/RX Log Capture Example = 
+
+This example of the Experiments Framework uses two WARP v3 nodes, one configured as an AP, the other as a STA.  The two_node_dual_flow_capture.py will capture a log file of LTG traffic flows between the AP and STA and write the data to an HDF5 log file for later processing.  This example demonstrates how to:
+ * Control two WARP v3 nodes from one wlan_exp script
+ * Use the wlan_exp framework Local Traffic Generator (LTG) to create traffic
+ * Capture an HDF5 log file from the data logged by each node
+
+The flow of the two_node_dual_flow_capture.py script is:
+ 1. Initialize two WARP v3 nodes
+ 1. Ensure nodes are configured as one AP, one STA and that the STA is associated with AP
+ 1. Start a fully-backlogged locally generated traffic (LTG) flow from AP -> STA
+ 1. Wait 30 seconds
+ 1. Start a fully-backlogged locally generated traffic (LTG) flow from STA -> AP
+ 1. Wait 30 seconds
+ 1. Stop the locally generated traffic (LTG) flow from STA -> AP
+ 1. Wait 30 seconds
+ 1. Stop the locally generated traffic (LTG) flow from AP -> AP
+ 1. Read the log data from each node and write an HDF5 log file
+
+To run this example:
+ * Setup wlan_exp (see [wiki:../../GettingStarted Getting Started] for details)
+ * Configure two WARP v3 nodes with the 802.11 Reference Design bitstream- one AP, one STA
+ * Open the file in a text editor and change the {{{NODE_SERIAL_LIST}}} to match your serial numbers
+ * Open a Python shell
+ * CD to the '''Python_Reference/Examples''' directory from the expanded 802.11 Reference design archive
+ * Run {{{python two_node_dual_flow_capture.py}}}
+
+The script will run for 2 minutes, then display its results:
