Radio Tomography Imaging

Since I conduct research on tomography area, I thought writing a small article as an introduction to many who does not know about this.

Radio Tomography Imaging (RTI) is a technique used to generate 2D images of the change in the electro-magnetic field inside the area covered by the radio transceivers to spot the presence and movements of animates (e.g., people,
large animals) or large metallic objects (e.g., cars).

Below are some graphs of the basic experiments I conducted to see this effect. I have plotted two plots per graph. Clear Line of  Sight (LOS) and a man standing in the middle(LOS) disturbing the link which allows us to see the difference clearly. Plot is for a single link, using many distances. Plotted graphs using matplotlib. Here is the link for the code.

Sniffing GSM traffic with hackRF

Image
This post is realted to my previous post , where the tools that should be pre installed are mentioned. Gqrx which is preinstalled in the live DVD can be used to visualize the frequencies. Here are examples of gqrx  tuned to different frequencies observed from channels captured from hackrf_kalibrate. (see my earlier post) Tuned to frequency 950.8MHz. Tuned to 959.6MHz. Then we need to run the grc script airprobe_rtlsdr.grc which is located at gr-gsm/apps folder found in the pre installed gr-gsm. Here is a screen shot of the flowgraph. I set the default value of gain to 40, which increases the packets captured from wireshark which is later explained. Here is a screen shot when I run the flow graph. Then we have to run wireshark from another terminal. Interface is loopback interface (lo). Use the following command, which runs wireshark as root user with icmp and gsmtap filters. sudo wireshark -k -Y 'gsmtap && !icmp' -i lo Here is a sc

Save recorded data with hackRF to a .raw file

Image
HackRF receives data at a very high speed. It produces about 1GB data within 40 seconds of recording. These data can be saved to a file, to process later. I use the .raw file format here. The file can be created separately in .raw format and use a flow graph to record data. But the easiest way is to use the following command which creates the file and save data in one command. hackrf_transfer -r .raw -f  433000000 -s 20000000 Further info about hackRF_transfer command:                      about naming a file: You can use CTRL+C to stop recording data. Flow graph method: Waterfall Sink block allows us to see live data being recorded by HackRF and File Sink block saves data to the file named.
