Intel CSITool Data Collector

This repository contains modified csitool for data acquisition.
This tool only supports IWL5300-based CSI collection.

These tools are tested with BPI-R2 device.

Preparation

Kernel & Driver

If you are using BPI-R2, please refer this README. If not, please look here.

Install lorcon

• Git clone https://github.com/dhalperi/lorcon-old
• make and sudo make install on ./lorcon-old/

Download this repository

• Git clone https://github.com/wldh-g/iwlwifi-csitool-apps
• cd iwlwifi-csitool-apps

Install firmware

• sudo cp firmware/iwlwifi-5000-2.ucode.sigcomm2010 /lib/firmware/iwlwifi-5000-2.ucode
• Append .disabled on all iwlwifi-5000-*.ucode on /lib/firmware. (e.g. iwlwifi-5000-5.ucode to iwlwifi-5000-5.ucode.disabled)

On transmitter

./prepare_tx.sh
cd ./injection; make
./random_packets [packet_count] [packet_size] 1

On receiver

./prepare_rx.sh
cd ./capture; make
./log_to_file [filename].dat

How to use recorded .dat file

Here is the tools that I used to process dat file: 15na-tools
And here is the tool provided by the author of Intel CSITool, D. Halperin: linux-80211n-csitool-supplementary

About channels, MIMO, MCS

Initially the scripts are configured to use channel 64 in HT40- mode, and to use 1 Tx antenna.

Changing Antennas (MIMO) & MCS

You have to change prepare_tx.sh. In # Set transaction rate part of prepare_tx.sh, there is a strange hex integer: 0x4d01. That may the only part you're going to modify.

Using get_flags.js, you can get proper flag code by giving the data rate and the number of antenna you use.

The detail for the flag is described at here.
