    195 By tweaking the transmit power (values of 0 to 15dBm) of the access point, you should be able to see a difference in throughput of the iPerf stream:
    196 {{{
    197 $ iwconfig wlan0 txpower <0-15>
    198 }}}
    199 
    200 For this tutorial, leave the txpower set to default (15 or 20dBm) for the first experiment runs. If the effect of moving the mobile node is too limited, you can try lowering the txpower.

     200For this tutorial, leave the txpower set to default (17 or 20dBm) for the first experiment runs. If the effect of moving the mobile node is too limited, you can try lowering the txpower.
    201201Note that each antenna at the w-iLab.t is equipped with a 10dB attenuator (so 20dB attenuation per link).
