I am a University student doing a project and I was wondering if someone would have the answers to some of my questions.

I am required to do a Data Throughput vs Distance test for Dial Up Networking via Bluetooth (Phone acting as modem for the laptop).

What program or method could I use, to best determine the data throughput rate between my phone and my laptop. I need a consistent and fairly accurate way, so I can test the data throughput at different distances.
