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 | | }}} |

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. |
| 195 | By tweaking the transmit power (values of 0 to 17dBm) of the access point, you should be able to see a difference in throughput of the iPerf stream: |
