I have been working with the networks analysis of Android devices for some time now. As many of you know, IPerf is a great utility to characterize the network bandwidth and packet loss on devices.
On Android too, there are quite a few tools that you could use to benchmark your network and your device. IPerf is certainly one of them. It was build by NLANR / DAST (I couldn’t trace back to this organizations website though) and is available for download here :
- For linux : http://sourceforge.net/projects/iperf/
- For windows you can use Cygwin (http://cygwin.com/) and install the iperf package
- For Android this tiny little app is perfect : link here
- IPerf needs a client and server setup. So, in the example that I am going to tell you I am setting up my laptop as the client and my android device as my server.
- Data is sent from client to server!!
- IPerf can only work over a single link. That means you have to get both your device under the same subnet and also ensure that there is at max 1 hop.
- Run IPerf app on your android device
- Enter “-u -s” in the text box that appears saying “Iperf command line arguments”
- Press the button on the left top corner which reads “OFF” and turns “ON” to a green one on touching it.
- Now your Iperf server is running.
- Run Cygwin terminal on your laptop.
- Type “iperf -u -c 192.168.238.101 -b 10M” and press enter
- That should enable you to start experimenting.
