Hello,

i would like to use the FalconGui for a SDR tech-demo, but unfortunately i am not able to find the cell in FalconGui.

To find the cell frequency and ID i used: https://github.com/JiaoXianjun/LTE-Cell-Scanner with an RTL-SDR:
with the following command:

CellSearch -s 1810e6 -e 1830e6 -p 1

Output:

Detected a FDD cell! At freqeuncy 1815.2MHz, try 0
    cell ID: 376
     PSS ID: 1
    RX power level: -18.6699 dB
    residual frequency offset: -11389.2 Hz
                     k_factor: 1.00001

For FalconGui i used a Ettus B200, that i previously tested with Gqrx.
I used the frequency and CID as input for FalconGui and got the following log:

I have also tried this with several other Cells i have found with LTE-Cell-Scanner. A few times FalconGui found some PDCCH but discarded them without further information.

Can you help me with further information, what i am missing for this setup or how to debug it? May it be related to the usage of a B200?

Best regards,
Joe

I'm interested in getting PRB utilization in TTI level for a cell (1 ms). I saw COLUMNS collected by FALCON contains 'nof_prb', # number of allocated PRBs, but not sure how to convert it to a cell PRB utilization/ms with other COLUMNS. Is it possible in FALCON ? if possible, how to derive the PRB utilization/ms?

Greetings,

I was trying to build falcon in Ubuntu on ARM, but am unable to do so. I think this is because of a bug (#265) in the patched version of srsLTE that the falcon cmake scripts download and compile.

First, I changed the DISABLE_SIMD option in falcon's CMakeLists.txt from OFF to ON, then proceeded to try to build falcon following the instructions. The cmake step completes without errors, but make fails with:

/home/localadm/falcon/build/srsLTE-src/lib/src/phy/fec/turbodecoder.c:170:22: error: ‘sse16_win_impl’ undeclared (first use in this function)
  170 |       h->dec16[0] = &sse16_win_impl;

According to the srsLTE/srsRAN_4G bug I linked above, srsLTE 18.09 does not build correctly when SIMD instructions are unavailable. The recommendation in that thread is to either use srsLTE 18.06 or to wait for the next release after 18.09 (which I believe ended up being 18.12).

Would it be possible to update falcon to build and run against a version of srsLTE 18.06 or 18.12 with your patches applied to it? Or to provide diffs of your patches to 18.09 so I can attempt to patch one of these versions myself?

Thanks in advance, and thanks for all your work on this software!

Firstly, many thanks for developing FALCON, it looks to be a really great way to analyse LTE networks.

I'm trying to use FALCON but have run into an issue: the output from using FalconEye directly differs from when I use FalconCaptureProbe and then analyse the captured file with FalconEye. Specifically, when I use FalconEye directly, several RNTIs are detected, but when I capture with FalconCaptureProbe then run FalconEye on the captured file, no RNTIs are detected.

A bit of background – my laptop is rather old so not particularly suitable for real-time decoding. So I decided to capture to a raw file and process the capture later. However, when I tried this FALCON didn't detect any RNTIs. I then tried FalconEye directly (reading from the USRP directly) and was surprised that several RNTIs were detected.

My setup is as follows: Dell Latitude E5420 laptop running Ubuntu 20.04 LTS, connected to a USRP B210 over USB 2 (I hope to get a USB 3 express card shortly).

To demonstrate the issue I ran two experiments. Both experiments used the same frequency and cell ID, and the second was run a few minutes after the first.

1. Run FalconEye directly. The log file of this is in experiment-1.log, and FALCON detected 20 RNTIs.
2. Run FalconCaptureProbe, then run FalconEye on the captured file. With this experiment, no RNTIs were detected. There are several files from this experiment:

• experiment-2_capture.log is the log from running FalconCaptureProbe
• experiment-2-unknownOperator-cell.csv / experiment-2-unknownOperator-iq.bin / experiment-2-unknownOperator-txpower.csv are the output files from running FalconCaptureProbe
• experiment-2_falconeye.log is the output from running FalconEye on the capture file.

Both experiments captured for 5 seconds, however since there is no way to limit FalconEye capture to 5000ms, I monitored it and manually cancelled it after 5 seconds had passed.

My guess would be that I'm mis-configuring something, or am mis-understanding how FalconEye / FalconCaptureProbe is supposed to work. I'd really appreciate help in understanding how to correctly use FalconCaptureProbe.

Many thanks!

Hey there,

just to leave a comment, I needed to downgrade to SoapySDR 0.7.2 on Archlinux for the AUR package to work.
Also, I needed to install qt5-charts package for falcon to build.

I am using LimeSDR Mini which has different signal paths in the mixer. By default, the high frequency mixer (LNAH) is selected; for LTE bands below 2 GHz, selecting LNAW improves the signal strength massively.

As far as I can see, rf_args is not implemented in the GUI, so cannot be set.

Getting the following error when falcon is trying to build UHD support, probably because my UHD version 4.0.0 is too new?

      |  ^~~~~

Also, tried to set environment variables for srsLTE which I already have built and running fine, but it's unclear which directory they need to point to - I've set them into the srsLTE git source dir:

SRSLTE_LIBRARIES=/home/xxx/LTE/srsLTE/build/lib/
SRSLTE_INCLUDE_DIRS=/home/xxx/LTE/srsLTE/lib/include

but cmake still doesn't find them and downloads your flavour of srsLTE. Any hints on how to resolve greatly appreciated.

I'd like to contribute a Prometheus exporter and Grafana dashboard to see the realtime results of LTE scanning over time.

srsRAN seems to support doing this, but I don't know about srsLTE and I don't know about doing that when it's use in Falcon.

Is this already supported and I've just overlooked how to enable it?

The use case is I'd like to identify the downlinks available and as many metrics about the health of those downlinks as possible.

For example, I'd like to setup a system capturing data for 72 hours and periodically capture data about the LTE network at that location.

Types of data I'd like to capture export:

• Identify what towers and downlinks are present
• Identify the signal strength, quality, and interference for each
• Identify the load, and other available metrics about each downlink
• Stretch goal, measure or estimate the number of client devices present

What metrics could be made available in this tool?

I can't seem to figure out how to run FalconGUI straight from my B200 - for scripted use FalconEye works fine, but for visualisations it would be neat to be able to run FalconGUI in the same way. Is that not supported?

Hello, I am using srsRAN to build eNB. I want falcon to listen from eNB of srsRAN. Can I use ZeroMQ to connect Falcon and eNB.?

Has anyone tried like this? if yes can you please help? or any idea how I can do this?

Many Thanks
