 === Experiment Execution ===
+==== Configure the mobile PAAM ====
+COSMOS uses a RESTful [https://wiki.cosmos-lab.org/wiki/Resources/Services/ArrayMgmt service for PAAM management]. A local version of this service is running on each mobile PAAM to allow for configuration outside of SB1. There are two paradigms for array management:
+ * Dynamic array management - The user connects to the antenna using {{{connect}}} command, dynamically steers the antenna during the experiment using {{{steer}}} command, and disconnects once the experiment is done.
+ * Static array management - The user can connect, steer, and disconnect in a single command, {{{configure}}}
+We will use mob4-1 as our transmitter. We will enable it to use all ICs and 16 elements with V-polarization. Initially, it will be steered towards broadside (0,0).
+{{{#!shell
+root@mob4-1:~# curl "http://rfdev-mob:3000/array_mgmt/enable?dev_name=Local&ics=all&num_elements=16&txrx=tx&pol=v&theta=0&phi=0"
+}}}
+Now we configure mob4-2 as the receiver with the same parameters.
+{{{#!shell
+root@mob4-2:~# curl "http://rfdev-mob:3000/array_mgmt/enable?dev_name=Local&ics=all&num_elements=16&txrx=rx&pol=v&theta=0&phi=0"
+}}}
+
+==== Run the experiment ====
+Open GNURadio companion on the sessions initialized with {{{-Y}}}
+{{{#!shell
+root@mob4-1:~# gnuradio-companion
+}}}
+{{{#!shell
+root@mob4-2:~# gnuradio-companion
+}}}
+
+On mob4-1, open the TX_OFDM.grc file. On mob4-2, open the RX_OFDM.grc file.

+==== Observe and improve the results ====
